摘要：
Three groups of 40 perch breeders were reared in order to study the effects of 3 different levels of dietary n-3 and n-6 fatty acids on egg quality. Two experimental diets, R1 and R2 (n-3/n-6 = 0.13 and 35.54, respectively), were compared to one commercial food, R3 (n-3/n-6 = 3.48.). Spawning and fertilization rates were high for diets R I and R3, which displayed a n-3/n-6 ratio of 0.77 and 2.34 in the eggs, respectively, by comparison with R2 (n-3/n-6 = 4.87), which produced low reproductive performances. We can conclude that dietary n-3 and n-6 FA levels influence egg and larval quality of Eurasian perch.
