SEASONAL CHANGES OF CHOLESTEROL IN THE TISSUES OF MALE CATFISH MYSTUS CAVASIUS (HAM) IN BHADRA RESERVOIR, KARNATAKA, INDIAH.M. ASHASHREE AND H.A. SAYESWARA
Seasonal variation in cholesterol of the different tissues of the freshwater catfish Mystus cavasius was investigated from Bhadra Reservoir. The amount of cholesterol in liver, muscle and testes was measured. A decline was recorded during the period when the gonads were passing through the peak ripe stage. The highest value of the cholesterol was however attained before this phase of gonad maturation. Concentration pattern of liver cholesterol seemed related to variations in the cholesterol metabolism of the fish, necessitated, besides other factors, by the demand for sex hormones. A possibility of the influence of feeding intensity on liver cholesterol content has also been indicated.
