Abstract:
Very-low-density lipoprotein (VLDL) is one of the major groups of lipoproteins made by the liver from triglycerides, cholesterol and apolipoproteins that enable them to move within the water-based solution of the bloodstream and help deliver endogenously synthesized triacylglycerols to adipose tissue thus converting the residue to low-density lipoprotein (LDL) and vice-versa for de novo cholesterol synthesis at peripheral tissues. The study was carried out to assess the seasonal profile of VLDL in amur common carp during four seasons (spring, summer, autumn and winter) among different age groups and sexes. The assumption on the homogeneity of variances was tested for serum, muscle, gonadal and hepatic VLDL and found not satisfy based on Levene’s F test. ANOVA (2-way) for serum, muscle, gonadal and hepatic VLDL 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. The above findings revealed age and seasons have profound effect on the general well-being and reproductive physiology of amur common carp as indicated by the gonadal cycle and changes which undertakes the importance of this lipoprotein in fish gross welfare regime.
