Abstract
The study deals with the seasonal variation in relative abundance of natural diet, Gastro-somatic index (GaSI) and relative gut length (RLG) values of different age groups viz. 0+,1+,2+,3+ & 4+ of Garra gotyla gotyla ranging from 4.2 to 14.7 cm TL, captured from different sections of River Tawi. (Latitude 32° 02' 20.23" N & Longitude 75° 16' 56.14" E) The result revealed that fish is planktyherbivorous and bottom feeder feeding on approximately 75.03%, 76.13 %, 78.82 %, 79.88%, and 81.52% phytoplanktons in 0+, 1+, 2+, 3+ & 4+age groups respectively. The RLG values was observed to increase from 0+ (5.51) age group to 4+ (6.82) age group while GaSI was maximum (12.65) in immature 0+ age group and decreases with increase in the fish age.
