Fry of Atlantic salmon (Salmo salar) fed a diet containing isolated fish protein grew significantly faster than those fed a diet containing casein without supplemental amino acids, and had improved feed conversion and lower mortality. Supplementing the casein diet with essential amino acids to the levels in the isolated fish protein diet significantly increased growth rate, reduced mortality, and improved feed conversion.When fingerling rainbow trout (S. gairdneri) were fed diets containing soybean meal as the sole source of protein, additions of amino acids to simulate those levels of essential amino acids in trout eggs and isolated fish protein significantly improved growth. Additions of methionine, lysine, histidine, and leucine individually and in several combinations had no effect.

The concentrations of major constituents of ovarian fluid were found to be lower than reported values for the same constituents in blood and urine of rainbow trout (Salmo gairdneri). Glucose and total bilirubin were significantly correlated (P < 0.05) to hatchability, whereas LDH was negatively correlated (P < 0.05).Rainbow trout egg proteins are highly nutritional and contain a higher proportion of essential amino acids than do eggs or human or cows' milk.
