Abstract :

Fish lipid is regarded as quality lipid being rich in cholesterol, triglyceride and essential fatty acids. Seasonal changes of total lipid content of the liver, testis and muscle were studied in the freshwater male catfish Mystus cavasius. Relatively, the lipid level increase in testes during maturation was related to simultaneous decrease in the liver and muscle. The Gonado Somatic Index also increased during these stages. Different phases of maturation were associated with marked quantitative fluctuation of lipid contents. This quantitative variation of total lipid content in different tissues was discussed with respect to the stages of reproduction.
