Nutritional Quality of Artemia salina as a Living Feed for Fish Larvae

Abstract

Nauplii of Anemia saliva from Brazil, San Francisco and China in 1981 were analyzed for nutritive components in order to clarify their food value to fish.
There was no appreciable difference in the proximate compositions of nauplii of Anemia saliva among the three locations. Calcium content of Anemia nauplii from China was about twice as much as that from Brazil and phosphorus content was about a half of that from Brazil. Vitamin B₆ content in nauplii of Artemia from China was lower than that from San Francisco and from Brazil. However, there was no remarkable difference in the contents of niacin, biotin, pantothenic acid and ascorbic acid in nauplii of Anemia among the different locations. Artemia nauplii from San Francisco, Brazil and China were found to be high in contents of ascorbic acid and ascorbic acid 2-sulfate. No conversion of ascorbic acid 2-sulfate into ascorbic acid was observed after starvation of newly hatched Artemia for 42h. Fatty acid composition of Anemia from San Francisco was found to be high in the content of linolenic acid and quite low inthe contents of eicosapentaenoic acid and docosahexaenoic acid.
