A well balanced diet rich in all important elements is required to maintain excellent health. In this perspective, fish is a nutritious diet that is high in important nutrients. It is a source of a familiar group of Polyunsaturated Fatty Acids (PUFAs) specifically omega-3 and omega-6, which can avert atherosclerosis and thrombosis. These fatty acids have defensive effects on coronary heart diseases, autoimmune disorders, arrhythmias, lowering plasma triglyceride levels and blood pressure. Aside from that, in tropical regions, fish is more readily accessible and less expensive than that of other animal proteins. Practically all the minerals existing in fish that are obligatory for the human body. The minerals present in fish Fe, Ca, Zn, P, Se, F and iodine as well. These minerals are with maximum bioavailability that can straightforwardly absorb by our body in the count of proteins and amino acids from fish sources became more freshly positive health effects on human health. Fish-derived lipids, which include omega-3 PUFA like EPA and DHA, aid to prevent cardiovascular illnesses in addition to helping to manage blood pressure. Iron aids in the formation of haemoglobin and hence avoids anaemia. Selenium is essential for thyroid gland function. Rickets are prevented by the calcium and vitamin D found naturally in fish. Vitamin A aids in the maintenance of normal eyesight and an immune system. The authors of the current review study made an effort to explain the value of the nutrients found in fish for human health. A campaign to raise awareness of the advantages of eating fish for health is also suggested by the author.


Fish, Nutrition, Minerals, Vitamins, Human health


Fish has been a significant constituent of the eating regimen of people in practically all nations on the planet since the beginning of time. Fish are the only cold-blooded, strictly aqua species with a slender body and dorsal side sensory organs [1]. Fish is often represented as a protein, and is frequently used in human diet. Like additional animal sources for nourishments, for example, eggs, milk and meat, fish has maximum protein value and its edibility surpasses 90% [2]. Due to their role in energy production, repair and regulating functions, nutrients are crucial for optimal health and a higher quality of life. The moisture, proteins, lipids, vitamins and minerals are significant macronutrients and phytochemicals which suggest the fish meat has nutritive significance [3,4]. It contains vital nutrients, particularly proteins with significant biological qualities and fats and is often referred to as "rich food for poor people." Sujatha, et al., are supplied by fish. Fish's nutritious value is determined primarily by its protein and fat content. Fishes provide important nutritive contents such as high quality protein, fats, vitamins and minerals such as magnesium and phosphorus [5]. Fish serves as a food supply and a means of protecting people from various diseases across the world [5,6]. Fish has a healthy amount of protein, ranging from 13% to 20% by fresh weight and all the necessary amino acids. Fish can include a variety of fats. It ranges from 0.2 to 15 percent and depends on the species [7]. Children's maturation and the emergence of cardiovascular disorders like coronary heart disease are both aided by fat from fish species. Calder, et al. noted that they contain PUFA, particularly omega-3 fatty acids, which are polyunsaturated fatty acids [8]. It also ensuring healthy prenatal cognitive development, avoiding premature birth and assuring healthy birth weight [9].

The most significant of these are fish lipids, which for the most part contain a high measure of omega-3 unsaturated fats, principally α-linolenic acid, Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) the suppleness of which isn't adequate to give the suggested consumption levels of these supplements for developing human populaces. In this manner, actions have been made by the farming business to "help" omega-3 unsaturated fat substance of different items, counting milk, egg, and poultry. Omega-3 unsaturated fats have a few helpful effects on human wellbeing. They also secure against different mental issues, gloom, and hyperactivity issue specifically and cancer [10,11].

Furthermore, the significant wellspring of n-3 LC PUFA fish, and other sea foods have adequate number of amino acids, contain high extents of taurine and choline, the vitamins D3 and B12, and the minerals calcium, phosphorus, iodine, and selenium. Besides this, fish and other seafoods providing noteworthy amounts of vitamin A, iron, and zinc to populace if diverse wellsprings of these supplements are limited [12].

Literature Review

Numerous studies conducted in the past several years have demonstrated the value of regular seafood eating for excellent health at any age. The prevalence of major vascular illnesses, diabetes, metabolic syndrome, obesity and neurological disorders have all been shown to be negatively correlated with fish intake [13,14]. Due to these factors, food recommendations are given the including seafood in a balanced diet at least 2 times per week according to U.S. department of agriculture. Fish is an essential nutrient in the human diet and is also present in the global aquatic product industry for consumers. Unfortunately, mostly the aquatic ecosystems and living organisms suffer from environmental impact by emissions of volatile organic substances and pollution of water by oil chemicals and many various hazardous agents. Therefore, we also should to protect our aquatic environment against to pollution on various environmental and ecological effects [15,16]. This viewpoint seeks to present a comprehensive and integrative model that facilitates nutrients, bioactive substances of seafood.

Nutrient profile of fish

The nutrients outlining of fish shows that fish are the significant part of the human eating regime having good natured medical advantages [17]. Fish comprises of proteins and different nitrogenous mixes, lipids, minerals and nutrients and an exceptionally low degree of carbohydrates. Protein substance of fish blows to almost 20%of the body weight. Fish, particularly saltwater fish, is high in omega-3 unsaturated fats, which are heart friendly, saltwater fish comprises significant levels of iodine [18]. The biochemical composition of fish is mentioned in Table 1. In Figure 1, which provides a visual depiction, the key elements of fish/seafood are outlined [19].

Fish as a functional food

The prime micro nutrients recognized as progressively thought and additionally bio available from animal source like iron, zinc, vitamin A, vitamin B12, and calcium are the key nutrients in the human diet [20]. For populaces in Africa and South Asia, fish normally originated from uninhabited sources (either aquatic or domestic), cultivated fish is progressively consumed by the poor folk [21]. This brings up significant issues about the nourishing constituent of that fish, and especially cultivated fish must be observed as a 'functional food'. Functional nourishments are the diet items clearly intended to carry healthfully significant components ready to correct body capacities and reduce the danger of specific ailments [22-24]. In this way, functional nourishments can limit clinical consideration costs while improving our health. Roberfroid, et al. mentioned 5 methodologies for the improvement of functional food items that comprise:

• Exclusion of an alimentary component which is hazardous.
• Supplement of nourishment constituents that aren't normally existing and helpful impact on health.
• Replacement of nutritional constituents that consumption at more significant levels may be destructive with a part that has an advantageous impact on wellbeing.
• An expansion of bio-availability or security of food constituents that are valuable for human.
• A rise in the measure of usually occurring constituent to a level that will have a useful impact on health.

Functional foods appear to have more medical advantages comparative with standard nourishments although it should be underscored that huge numbers of the normal food sources, counting equally animal and plant stuffs, are rewarding for good [25].

The healthful element of fish muscle differs as it inclines to be influenced by species type and the physiological condition of a creature including age, sexual development degree, size and by different hereditary and nutritious components [26-29].

Additionally, the proof demonstrates that the nature of animal based food items mainly related to creatures taking care of does [30]. Fry, et al., proposed a calculated structure that explained possible associations among at present utilized raw resources in aquaculture feedstuff and its impact on ecological wellbeing and human nourishment [31].


Proteins are significant for the development and improvement of the body, upkeep, and fixing of destroyed tissues. Proteins from fish considered taking an extreme health advantage. Sea creature foods having maximum protein levels than most earthly meat [32]. With over 3.3 billion people worldwide receive roughly 20% of its average per capita consumption of animal proteins from seafood, that has a higher protein composition of 18%–20%, Moreover, oceanic protein is extremely absorbable and wealthy in a few peptides and fundamental amino acids that are limited in earthly meat protein, like lysine and methionine recommended by Tacon and Metian, et al.

Fish muscle is a highly nutritious form of protein that may meet the requirements of customers of every age, from young children to elderly people. It is composed of short fibres interwoven with thin barriers of consistently over time collagen. Fish proteins, particularly mostly from lean fish, were demonstrated to improve insulin levels, hence preventing type-2 diabetes [34]. Due to its capacity for healing process, skin anti-aging and osteogenesis, marine collagen, the primary protein of the connective tissue found in fish skin, bones, and scales, is highly sought-after for aesthetic, nutraceutical and pharmaceutical purposes [35]. Fish proteins and protein hydrolysates' bioactive peptides have been demonstrated to have a number of health-promoting properties, including those that are anti-hypertensive, anti-diabetic, anti-coagulant, antiinflammatory, anti-microbial and antioxidant [36-39].

Amino acids serve as the fundamental building blocks for proteins, but they also act in the human body in a number of other ways, including as the control of gene expression, nutrition transport and metabolism, thermogenesis, hunger management, and immune response modulation [40]. Seafood is among the few food components of taurine, a sulfurcontaining free amino acid-derived molecule that protects cells and tissues against free radicals [41]. Taurine is engaged in a variety of physiological functions, including bile salt generation and fat digestion, membrane stability, fluid balance and immune-modulatory, and has a positive impact on digestive, endocrine, immunological, muscular, neurological, reproductive and visual functioning [42].

Dort, et al., discovered cod protein to all the more likely advance development and recovery of skeletal muscle after injury compared with peanut protein and casein proposed likewise to be mostly a result of better goals by an aggravation of cod protein [43]. Calcitonin preserves bone quality and has been utilized for the cure of metabolic bone infections as osteoporosis and Paget's sickness and has likewise indicated potentials in cure of osteoarthritis and to decrease postmenopausal osteoporosis [44].

Drotningsvik, et al., showed that low dietary intake of cod protein (25%) contrasted with casein just eating in routine, enhanced lipid digestion and glucose guideline in obese rats [45]. For people indicated that a month of an eating regimen with 60% of protein from lean-fish decreased serum triacylglycerol concentrations and prevented elevation VLDL molecule in number and contrast with eating in routine without fish proteins [46]. In a subsequent report, the lean-fish consumption appeared to diminish postprandial C-peptide, and lactate focuses just as the TG/HDL-cholesterol proportion [47].

Essential fatty acid

The most well-known and researched benefits of marine fisheries are those attributed to its unique lipid profile, namely its high amount of LC-omega-3-PUFA and low level of saturated fatty acids and cholesterol. Recent research has underlined the necessity of a steady supply of seafood with aging for its function in the protection of cognitive impairment and neurological illnesses [48,49]. The fatty acid content of marine foods varies widely depending on the species as well as a number of intra-specific (independent and make, age, and reproduction stage) and external (catching season, habitat of provenance) variables.

Omega-3s are a group of long-chain polyunsaturated fatty acids that are fundamental elements for health improvement. Research exploration shows that there are two most useful omega-3s are EPA (Eicosapentaenoic corrosive) and DHA (docosahexaenoic corrosive) they have a few valuable effects on human body. These incorporate diminishing the danger of myocardial localized necrosis bringing down pulse and triglyceride concentration in the blood upgrading the resistant system and maintaining brain function [50-52]. They likewise ensure against different mental issues, depression and attention deficit hyperactivity issue specifically in cancer.

The bioavailability of n-3 PUFA from invigorated diets is like pharmaceutical/dietary enhancements [53]. However, human ingestion of n-3 PUFA from food items has been accounted for to happen at quicker rates contrasted with supplements [54]. The unsaturated fat profile of fish muscle can be controlled by adjusting the unsaturated fat structure of fish diet and subsequently, it is basic that cultivated fish for the most part have lower rates of n-3 PUFA contrasted with fish in nature [55]. This is caused to a great extent by the replacement of dietary fish oil principally created from marine species (for example herring, sardine, sand, eel, anchovy, cod, krill) with vegetable oil in the consumption regimes for aquaculture species rendering the nutritious nature of fish meat. Thusly, elective raw materials and added substances are being recognized for consideration in fish feeds to improve fish unsaturated fat profile adding to medical advantages related to the utilization of strengthened fish items [56]. Tocopherol (vitamin E) is a known cancer prevention agent that which prevents fatty acid oxidation in cell membranes and a speculation exist that vitamin E and n-3 PUFA levels are tightly related in tissues. Navarro et al., saw that tilapia took care of diets enhanced with vitamin E (100 mg/kg–150 mg/kg diet) had improved n-3 to n-6 proportion just as a significant level of PUFA in muscle tissue [57]. There have additionally been actions to build certain harvests to gather elevated levels of EPA as well as DHA in its seed oil. Genetically designed Camelina has been accounted for to be a source of n-3 PUFA and in this manner, give significant levels of these unsaturated fats in cultivated fish took care of decreased fish oil withholds from food without weakening their dietary quality [58].



In addition to their valued essential oil and protein composition, fish is similarly a noteworthy source of micronutrients (minerals and vitamins).


All the vitamins are vital for the good soundness of people's health. Fish is an unbelievable source of precise vitamins which hold important volumes in the body that are important in the growth and improvement of child’s body. Fish is a rich source of many vitamins, especially vitamin A, D, and E from oily species, just as thiamine, riboflavin, and niacin (vitamin B1, B2, and B3).

Vitamin A

In people, vitamin A shoulders a fundamental job in resistant system, development and vision [59]. Vitamin A insufficiency stays a significant reason for kid mortality and kid visual impairment (xerophthalmia) in low and middle income countries, albeit numerous nations have half-yearly vitamin A supplementation programs all through the world focusing on youngsters 6-60 months old [60]. Human body can change over provitamin-A carotenoids, accessible from orange and yellow products of the soil and green verdant vegetables, to retinol [61]. In any case, productivity procedure is variable and relies upon numerous components counting the food grid, food planning, utilization of dietary fat and even hereditary elements [62]. Stimulatingly, preformed retinol from animal source diets has more noteworthy integration and bio-availability.

In fish, vitamin A is a basic micronutrient that joined rightfully from the consumption of regime or utilized from carotenoids. Vitamin A has been demonstrated to assume a significant job as an immune stimulant and takes an especially gainful practice in fish cultivating [63]. Moren, et al., announced that expanding levels of carotenoids in the weight control plans were imitated in expanding levels of vitamin A in Atlantic halibut hyoglossus entire body and liver tissue that is by all accounts the capacity organ of nutrient.

Major distinctive vitamin A supplements had no impact on rough protein, lipid, moisture, and ash substance in the entire body. Indications of an excess of supplemental vitamin A, for example, diminished development and depigmentation, expanded death, have been accounted for in other species of fish [64]. Likewise, Hernandez, et al., saw that vitamin A in abundance could effectively affect the liver of Japanese struggle Paralichthys olivaceous [65]. The two examinations showing that dietary vitamin A supplementation might affect fish execution and regime assistance. Certain fish species, especially those expended entire with the head and viscera are known to be plentiful in vitamin A [66]. Indeed, Roos, et al., determined that even little creation of the vitamin A rich fish mola Amblypharyngodon mola in lakes in Bangladesh can meet the yearly vitamin A suggestion of 2 million teenagers. Katsuyama and Matsuno, 1988 detailed that tilapia Oreochromis niloticus, among different species including goldfish Carassius auratus and Atlantic halibut, ready to bioconvert beta carotene to vitamin A, recommending conceivable supplement of tilapia takes care of with beta carotene rich raw materials to improve vitamin A substance of the fish toward human health [67]. Vitamin A in fish liver must be stored when significant levels (above fish necessities) are enhanced in the feed. Be that as it may, raised levels of beta carotene can get harmful to tilapia or other fish and negative consequences for organic films and cell signal conduction have been accounted for [68]. Here are various foods plentiful in beta carotene that might develop vitamin A hotspots for fish counts calories. Omoregie, et al., demonstrated that nutritional consideration of sweet potato up to 15 percent didn't adversely affect the fish's final weighs [69]. Vitamin A supplement in fish regimes might be utilized to build vitamin A substance in few fish species, in the entire body or potentially liver, as long as the enhanced degree in takes care of don't surpass fish prerequisites and henceforth, don't represent a danger of incited poisonousness.

Vitamin D

Vitamin D is required for the strength of bones sickness remembering rickets for kids and osteomalacia in a grown up. Moreover, vitamin D inadequacy is related to a more serious hazard for gestational matured births [70]. People, especially who are existing close to the equator conclude a lot of its vitamin D from presentation to daylight, albeit inside living, air contamination, and skin shading are hazard issues for insufficiency. Fish is the most significant normal dietary source of vitamin D, in certain sceneries giving over 90 percent of nutrition, even though egg, meats, and mushroom are different bases [71].

Next to bones associated matters lack vitamin D has associated with diabetes, expanded forcefulness of specific tumors and expanded event of immune system illnesses just as heart maladies [72,73]. Generally, vitamin D can be photochemically delivered in the skin by the intervention of daylight. Because of worries about skin cancer or different explanations behind low presentation to the sun, as living on northern elevations, maximum paces of vitamin D inadequacy has been accounted for from kids and grown-ups all around the globe. The general proposal is to ingest at any rate of 1000 IU vitamin D for each day, which relates to 25 mg. Vitamin D found in fish is vitamin D3 (cholecalciferol), that is an additional structure actuality delivered in the skin from 7-dehydrocholesterol when presented to bright sunlight and that has as of late appeared to have multiple occasions higher power contrasted with the vitamin D2 that is found an example in mushrooms. Two structures vary by ergocalciferol having one twofold bond and a methyl bond more than cholecalciferol.

In fish, vitamin D assumes a similarly significant job in skeleton genesis and solidification and subsequently, satisfactory degrees of this fat-solvent nutrient ought to be given in the ingestion regime especially because of the photochemicals and non-photochemical creation of vitamin D impossible happens in fish [74]. Like, wild salmon have a 75 percent higher vitamin D level compared with cultivated salmon showing amongst others its useful impact on human health. However, different examinations on fish demonstrated significant levels of vitamin D causing hypervitaminosis, impaired growth, lethargy and discoloration [75]. In rainbow trout no connection was seen between vitamin D levels in muscle and the eating, routine recommending that involvement of substance exists for vitamin D in fish tissue. While an examination performed by Graff, et al., indicated that fish can be tolerant of high doses (up to 57 mg/kg feed) of vitamin D over a significant period [76]. Vitamin D is useful for people yet it can likewise decidedly influence fish affluence.

Vitamin D present in fish liver and oil is vital for bone growth since it is essential for the retention and ingestion of calcium. It additionally assumes a job in invulnerable capacity and may offer assurance against cancer. Slick fish is the best food wellspring of unfortified vitamin D. It isn't seen in numerous nourishments and tends as a nutrient that numerous defenceless gatherings go shy of, for example, high school young ladies and the old.

Vitamin E and K

Fish oil taken with vitamin E lessens levels of inflammation, joint inflammation, pain, and weakness normal for arthritic joint pain. Vitamin K present in fish is answerable for hostile to anti-haemorrhage factor [77]. Vitamin K forestalls interior draining and animates the right coagulation of blood.


Fish is a decent source of practically all the minerals present in seawater and the worth range from 0.4% to 1.5% (wet premise). The minerals present in fish incorporate iron, calcium, zinc (from marine fish), phosphorus, selenium fluorine, iodine. These minerals are with high 'bioavailability' implying that they are smoothly consumed by the body [78]. Accessibility of iodine and selenium in marine fish is of extraordinary importance according to the nourishing perspective. Iodine is significant for hormones thyroxin that manages body digestion and in kids, it is required for development and mental growth. Selenium is a fundamental antioxidant low component. Iron is significant in the combination of haemoglobin in red platelets for shipping oxygen to entire pieces of the body. Calcium is obligatory for solid bones (arrangement and mineralization) and the regular working of muscles and the sensual system. The intake of calcium, phosphorus, and fluorine is higher when little fish are eaten with their bones as opposed to disposing of fish bones.


Iron assumes a basic job in numerous functions of the human physique, utmost outstandingly in the creation of haemoglobin, that liable for the transportation of oxygen all through the body [79]. The worldwide ubiquity of anemia is around 33 percent and keeping in mind that the general commitment of iron versus other nourishing and non-wholesome causes in numerous settings isn't surely known, iron insufficiency is recognized to be a significant supporter [80]. Inadequacy through pregnancy builds the danger of maternal mortality, during youthful youth can influence the psychological turn of events.

Iron is a fundamental element in fish as well. Diverse fish species have distinctive iron necessities that alter contingent upon dietetic iron bio-availability. Iron can be profitable yet may likewise get hurtful to the animals and along these lines, dietary iron degrees for fish essentially firmly directed to give adequate focus to organic responses without the superfluous abundance which might be unsafe (for example oxidative pressure) assembly it hard to focus on the iron fixation that would profit human buyer. In rainbow trout, expanded degrees of nutritional iron caused the height of these micronutrients in blood just as gastrointestinal organs including the liver [81]. Trout, can manage raised iron focuses in the entire body by regulating the degree of iron in the blood and resultant for storage exchange in the liver. Thus, taking care of gilthead ocean bream with consumes fewer calories energised with iron and different metals counting zinc and copper, didn't majorly affect the grouping of these minerals in tissues [82].


Selenium a fundamental component in human and animal food. Selenium assumes a job as an antioxidant and catalyst for the creation of thyroid hormone stimulates working of the immune system, and acts as an antioxidant in cardiovascular disease and cancer prevention avoidance. Selenium works fundamentally in a type of seleno proteins and their job might be auxiliary and enzymatic. The bio-availability of selenium, which is a union of supplement retained and used by a living being to add the necessary physiological capacity, fluctuates significantly amongst various food types. In fish, for example, yellowtail kingfish Seriola lalandi, supplementation of fishmeal-based feeds with selenium in a type of selenocystine, selenomethionine, or business selenium addition, brought about expanded muscles selenium centralization of 0.35, 0.61, and 0.62 mg/kg, separately, contrasted with selenite which had no impact on the muscle selenium levels (0.24 contrasted with 0.21 mg/kg selenium in muscle in the basal-selenium lacking gathering) [83]. All the while, nutrient selenium degrees somewhere in the range of 15 and 21 mg/kg were shown as a limit level for adolescent yellowtail kingfish to forestall diminished feed admission, development, and any neurotic changes in fish tissues.

Selenium is poisonous in huge dosages; however, it is fundamental as a micronutrient in animals and people. In human, selenium capacities as seleno proteins as a cofactor for the decrease of assorted cancer prevention agent catalysts, for example, glutathione peroxidases and is likewise liable for the capacity of the thyroid organ as a cofactor for the three of the four known sorts of thyroid hormone deiodinases [84]. Effectively prior Kaneko and Ralston, et al. proposed an alleged selenium medical advantage esteem (Se-HBV) in light of the supreme sums and relative extents of selenium and mercury in fish as a rule for fish wellbeing [85]. All the more as of late, the gathering refreshed the Se-HBV incentive to not just consider the accessibility of selenium from fish yet additionally if the selenium status is upgraded or lessened. That new worth is condensed HBVSe to recognize from the prior Se-HBV [86].


Calcium is one more significant mineral in human nourishment being significant for bone thickness. Calcium salt gives unbending nature to the skeleton and calcium particles assume a job in numerous. The suggested per day calcium by WHO/FAO is 400 to 500 mg/d for grown-ups. Contrasted and different minerals, calcium absorbance to the body is generally wasteful. By and large, just about 30 percent of dietetic calcium is successfully ingested. Alongside milk and milk kinds of stuff, fish and fish bones are acceptable source of calcium and likewise indicated before that calcium ingestion from fish is similar to for instance skimmed milk.

Malde, et al., stated that salmon bone is described by nearness of profoundly accessible calcium and subsequently [87]. Calcium is for the most part aggregated in fish bones yet as much as possible likewise be put away in scales [88]. In event that the water is wealthy in calcium fish can assimilate calcium from their general condition to accomplish, somewhat, its calcium necessities. Something else, calcium must be gotten from the feed. Calcium necessity in fish may change with a sequential nearness of other dietary supplements, for example, phosphorus, that might influence fish entire body calcium substance [89-93].


Zinc is required for most body forms as it happens along with proteins in basic. Zinc lack is related to poor development, skin issues, and loss of hair among different issues. High-protein foods like meat and fish contain the most noteworthy measure of zinc, and it is effectively ingested from the sources. Shellfish give additional zinc than some other food [94-96]. Different kinds of sleek fish, for example, skate, anchovies, herring, sardines, crab, prawns, shrimps, mussels and winkles likewise give a lot of zinc.


Phosphorus assumes a significant job in bones. Likewise, it is additionally a segment of numerous intra cellular mixes as nucleic acids, nucleoproteins and natural phosphates as creatine phosphate and adenosine triphosphate. Phosphorus in the human body is around 700 g of which 80% are bound in the bones, 10.9% in viscera and 9% in the skeletal muscle tissues [97,98]. Phosphorus inadequacy in the body prompts strength issues, metabolic acidosis, encephalopathy, and modification in bone mineralization just like cardiovascular, respirational, neural, and metabolic disarranges. A few distributions fish are recommended to be a superior wellspring of phosphorus by a normal somewhere in the range of 204 and 230 mg/100 g phosphorus in fish, contrasted with 176 mg/100 g in the meats of an animal [99].


An integrated strategy involving biochemical science, food science, and nutrition should serve as the foundation for a developing and contemporary view of research on seafood, nutrition, and health status. Fisheries and aquaculture are recognized internationally for its contribution to lowering nutritional shortages and health hazards associated to diet. Aquatic foods are a rich source of nutrients and bioactive components essential for human health. In addition to highlighting the significance of taking food safety considerations into account, fish intake and its bioactive components are noted and encouraged for their positive effects on health.

Fish and fish products shoulder an extraordinary job in the wholesome picture since they are a rich source of nutrients and give a decent parity of protein, nutrients and minerals, and a generally low caloric substance. The utilization of uncommon foods, such as seaweeds, together with waste products and by products of the fish industry as sources of value-added compounds is now the next breakthrough in the bio-refinery and cyclical economic paradigms.

Several research have focused on the extraction of natural chemicals from seafood processing by-products, such as omega 3 fatty acids and tocopherol, and its recycling and reuse in the creation of novel food items for human diets in additional to functional ingredients. Around the same time, it is important to consider the applicable laws and safety considerations while applying developing technologies, like nanoscience. The investigation of novel usages is expanding, sparking interest in this scientific topic on a global scale.
