Abstract:
Phospholipids play a critical role in fish overall physiology and the role played in reproduction and its seasonal changes in different age groups and sexes have not been reported in common carp. The study was carried out to assess the seasonal change in phospholipid (PHO) lipoprotein concentration in amur common carp during four seasons (spring, summer, autumn and winter) among different age groups and sexes with relationship to breeding behaviour. The assumption on the homogeneity of variances was tested for serum, muscle, gonadal and hepatic PHO was tested and was not satisfy based on Levene’s F test. ANOVA (2-way) for serum, muscle, gonadal and hepatic PHO level were analysed for different age groups and sexes and observed significant effect among different age and seasons. Similar observations can also be seen between age and seasonal interactions. Similar observation could be seen between all seasons and target samples while conducting Tukey’s HSD post-hoc test for checking the means differences which correlates with the gonadal development and maturity. The above findings revealed that age and seasons directly correlates with the PHO level which forms an integral component for egg development and thus the gonadal cycle. Judicious selection of matured brood and dietary PHO supplement could help achieve better reproductive operation.
