| Abstract: | A ten-week feeding trial was carried out to evaluate animal proteins, either alone or in combination (1:1:1), on the growth performances and economic benefit of climbing perch, Anabas testudineus. Four iso-proteinous (40%) diets were prepared, using fishmeal, protein concentrate, and meat and bone meal as major protein source in diets 1, 2 and 3, respectively, while diet 4 consisted of an equal proportion (1:1:1) of the above protein sources. Triplicate groups of fish (0.53 ± 0.02 g) were randomly stocked in 12 earthen ponds at a stocking density of 40,000 ha?1. Fish fed diet 4 had significantly (P < 0.05) higher percent weight gain and SGR % per day?1 compared to the fish fed diets 1, 2, or 3. Significantly higher apparent protein efficiency ratio (1.25) and lower apparent feed conversion ratio (2.00) were also observed in fish fed diet 4. Total yield (1,123 kg ha?1) and net profit (Tk. 116,569 ha?1) were also higher in fish fed diet 4. It can be concluded that the combination of fishmeal, protein concentrate, and meat and bone meal is more effective for climbing perch than any of the three protein sources alone. |
