dc.description.abstract | The moisture content, crude protein level, and amino acid profile of three freshwater zooplank- ton (Moina micrura, Diaphanosoma excisum, Brachionus calyciflorus) commonly used for rear- ing fish larvae were analyzed using standard methods. The moisture contents and crude protein levels were similar, as follows: M. micrura 89% and 52.4%, D. excisum 89.3% and 57.3%, and B. calyciflorus 91.6% and 50.3%, respectively. The samples contained 17 amino acids: nine essential and eight non-essential amino acids. The dominant essential amino acids (per 16 g N) in M. micrura were lysine (10.73 g), arginine (8.17 g), leucine (8.0 g), and histidine (5.09 g); in D. excisum, lysine (9.95 g), leucine (8.0 g), valine (6.23 g), and arginine (4.78 g), and in B. caly- ciflorus, leucine (8.95 g), lysine (8.64 g), arginine (6.37 g), phenylalanine (5.20 g), and valine (4.83 g). In all three species, glutamine and aspartic acid dominated the non-essential amino acid profile, and methionine was the essential amino acid in the smallest concentration. Differences among amino acid profiles were insignificant (p>0.05). | |
