Author(s): Monjeet Sonowal, Santoshkumar Abujam and Shyama Prasad Biswas

Abstract: The present investigation has been carried out from the fish landing sites of Brahmaputra River at Guijan Ghat and Hilika Ghat (downstream of Maguri beel), Tinsukia district of Assam. For which, a total of 270 fish specimens were collected during March, 2015 to February 2016. The lowest value (0.34±0.52) of relative length of gut (RLG) of Glossogobius giuris was found in 5-7 cm length group whereas the highest values (0.47 ±0.14) in 11-13cm. It reveals that the fish falls in the category of carnivorous fishes. Gastro somatic index (GSI) was ranged from 1.88±.9 (January) to (April) to 3.72±1.3 (February) for males whereas, it was from 2.5±1.04 (April) to 3.4±1.5 (July) for female fish. It was noticed that the male feeding intensity was being peak during winter seasons (December to February) while, female feeding intensity was in monsoon season (June-August). Degree of fullness of gut reveals that 44 species were found full with 16.18%, 35 species were ¾ full with 13.1%, 48 species were ½ full with 17.9%, 24 species were ¼ full with 8.9%, 51 species were nearly empty with 18.88% and 68 species were absolutely empty with 25.0%.
