By means of essencial amino acid index and animal growth experiments, using the amino acid composition of the muscle in black sea bream juvenile as standard EAA requirement model for fish feed, The effects of nine different formulae of feed protein sources were compared. The amino acid balance and the nutritional value of the protein sources in feed for the juvenile of black sea bream were studied. Two formulae of protein sources were selected to be most effective, It suggests EAAI be an effective and simple assessment standard in studies on valuation of amino acid balance in protein sources of fish feed.

Mmol/L to juvenile Japanese sea bass, and 75.86, 63.46, 56.42 mmol/L to black rockfish. When pH is steady at 8.40 + 0.10, the 24-, 48-, 96-hour LC50 of Alk are 72. 79, 65. 28, 57. 92 mmol/L to Japanese sea bass, and 69. 47, 59. 37, 51. 96mmol/L to black rockfish. It is obvious that the toxicity of Alk to fish increases with the progressive increase of Alk or time when pH is at a constant level.3. According to analysis of variance of orthogonal test, pH and Alk have signification effects on the mortality rate of black rockfish.
