ABSTRACT

Total lipid contents of Puntius sophore (Ham.) were studied during the period of December,2019 to November,2020, from the river Dhansiri, Golaghat, India. The study sites lies between 26°42'11"N (Latitude) and 93°41'14"E (Longitude). The study period was divided into four seasons viz. winter(December-February), pre- monsoon (March-May), monsoon (June-August ), post- monsoon (September- November ). Lipid content varies seasonally at   different habitat ( lotic or lentic). The lipid content is seasonally varies significantly at 0.01 level. The lipid content of the fish is found to be higher in lotic habitat than the lentic habitat. Lipid content was higher during winter than Monsoon and Post monsoon season. In the present investigation it was observed that highest amount of total lipid found in winter in lotic habitat (301.62±14.62mg/g). The lowest value of total lipid in monsoon (107.23±4.67mg/g) and then gradual increase in postmonsoon (287.54± 36.74mg/g). It was osbserved during the study that a drastic difference in the total lipid content between lotic and lentic habitat was an important finding of the study. It may be noted that habitat condition and change of season have a significant impact on fat synthesis of the fish.

Key words: Lipids, habitats, lotic, lentic, monsoon etc.
