A 12-week triplicate feeding trials was conducted to assess the use of variousproteins, in combination with glucosamine by asiancat fish, Clarias batrachus (av. wt. 2.2+0.01 to 2.5+0.02 g) fingerling. Six (31.18 to 43.52 % CP, 15.53 to 16.76 kJ/g energy, and crude lipid 0.0 to 6.70%) practical diets were formulated using plant protein (PP) or animal protein (AP) with glucosamine @ 0.0, 0.5, 5.0 and 10.0 % with basal ingredients(F-1, PAG 0:100:0.5; F-2, PAG 0:100:5.0; F-3, PAG 0:100:10.0; F-4, PAG:: 100:0:0.5; F-5, PAG:: 100:0:5.0; F-6, PAG:: 100:0:10.0). The final weight gain was recorded as 21.2+1.4 g, 19.5+0.8 g, 19.6+0.2 g, 18.4+0.7 g, 17.5+0.6 g, 16.9+0.4 g and 13.24+1.2g in control. It is concluded that the growth is better in total animal protein feeds and the best growth (p<0.05) recorded in the feed incorporated with 10% glucosamine. The survival was recorded in between 60+4.1% to 73+ 2.8%. Results indicate that animal protein rich diets with glucosamine were much acceptable than plant protein and/or natural diets for C. batrachus, however, the growth performances and FCR with PPwere also improved, from control feeding trials, in combination with glucosamine
