Modification of nutritional properties of microalgae for Artemia breeding

Artemia (brine shrimp) is used as a live-feed stuff for seed fish in fish hatcheries and aquarium fisheries. Nutritional properties of Artemia are in close relationship with the nutritional facts of the microalgae it is fed by. In this study, 20 different microalgae and cyanobacteria (indigenous strains from Dunaliella, Isochrysis, Phaeodactylum, Tetraselmis, Nannochloropsis, Spirulina, Synechocystis, Synechococcus, Chlamydomonas, Chlorella, and Scenedesmus genus) were supplied to A. franciscana as food source and growth characteristics of A. franciscana and were followed during 10 days of growth. Seven microalgae strains were selected for Artemia breeding and dry weight, total protein, starch and lipid contents of microalgae and A. franciscana were recorded. Then, microalgae were exposed to N-, S-, P-deprivation and high salt stress for 5 days of incubation. Total lipid, protein and carbohydrate contents of those strains were recorded and 5-days stress exposed microalgae were supplied to A. franciscana as only food source. Lastly total lipid, protein and carbohydrate content of A. franciscana was followed during 10 days of growth. In most cases, feeding A. franciscana with D. tertiolecta was superior to other strains studied.
