General pattern of gonadal development in female Trachinotus ovatus was divided into six maturity stages, which are; immature, maturing, nearly ripe, ripe, spawning and spent stages. The maximum value of gonadosomatic index (GSI) was attained in June and July. Total protein content in ovaries varied according to different maturity stages recording maximum value at immature ovaries and minimum at spawning and spent ovaries. The values of GSI in ovaries were inversely correlated to their total protein content at different maturity stages. Seven amino acids (proline, alanine, valine, methionine, isoleucine, leucine and histidine) were found to increase significantly in ripe ovary, followed by a significant decrease in both spawning and completely spent... |
