Gonadal Maturation, Fecundity and Reproductive Potential of the Indoor Cultured Grunt, Hapalogenys nitens

The condition factor (CF) were calculated by the morphometric data, and gonadal maturation and reproductive potential associated with fecundities of indoor cultured Hapalogenys nitens were investigated by microscopic and morphometric analysis from August 2011 to October 2012. Monthly changes in the GSI and CF were closely related to gonadal maturation and spawning. The ovary consisted of a pair of saccular structure with many ovarian lobules, the testis is a pair of lobular structure with many testicular lobules. The relationship between total fecundity (F) and total length (TL) of fish was expressed as F=0.0449TL 2.7926 (r 2 =0.0653), and body weight (BW) was expressed as F=1.4492BW 0.8964 (r 2 =0.0863). In this study, some exceptional special cases and phenomena were observed: absolute and relative fecundities were not increased with the increases of total length and body weight, respectively. Absolute and relative fecundities were no concerned with the increases of age classes of total length (cm) and of body weight (g).
