Impact of Seasonal and Habitat variation on composition of Total Lipid content in Muscle and Liver of Labeo gonius ( Ham )

Fish lipid is regarded as quality lipid being rich in cholesterol, triglyceride and essential fatty acids. The changes in habitat and seasonal variation have a significant impact on the quality and quantity of different components of lipid profile. The present paper reports on the seasonal differences in the quantitative compositions of total lipid of Labeo gonius in lotic and lentic habitats. These nutrients were determined in muscle and liver tissues in four different seasons of the year (premonsoon, monsoon, retreating monsoon and winter). In lotic habitat the highest amount of total lipid (301.00 ± 2.73mg/g) was observed in retreating monsoon in the muscle tissue . Similarly in liver tissue the highest amount of total lipid was observed in winter (208.50 ± 1.84mg/g). Though apparently similar trend was observed in lentic habitat, but some amount of differences with higher values were observed in muscle tissue. The present study with comparative analysis of total lipid components reveals a significant impact of habitat and seasonal variation on the nutritional quality of lipid in Labeo gonius.
