Anserine and free amino acid contents in the egg and fry stages of developing rainbow trout (Oncorhynchus mykiss).
1. Anserine and free amino acid contents were examined in rainbow trout eggs, yolk sac and yolk-free fry before feeding. 2. Free amino acid levels showed little change in eggs and yolk sac and had a tendency to increase in yolk-free fry. 3. No anserine was detected in the eggs and yolk sac, but yolk-free fry significantly increased its concentration after hatching. This continuous increment of anserine was discussed in relation to buffering capacity of adult fish muscle.
