摘要: AbstractThe objectives of this study were to (1) evaluate if dietary lysine (Lys) has an effect on the free amino acid (FAA) pool Yellow Perch Perca flavescens eggs, and (2) determine how Lys influences reproductive performance eggs fertilization rate (embryo survival) female Perch. Two-year-old initial size approximately 75 g randomly distributed into six 400-L tanks at 32±1 fish per tank. This experiment included two wheat gluten-based diets in triplicate Lys-deficient ([−]Lys) Lys-supplemented ([+]Lys; 2.23% dry feed) diets. Females from reference group fed a commercial diet. reference, (+)Lys, (−)Lys groups stripped their divided 0.4–1.2-g portions mixed with sperm (21.4±4.3 μL) either or males. The mean weight females total ovulated greatest compared both (+)Lys groups. There ...
