Evaluation of Partial Replacement of Dietary Animal Protein from Plant Protein Blended with Glucosamine on Growth and Body Indices of Asian Catfish (Clarias Batrachus) Fingerlings

Abstract

A 12-week feeding trials was conducted to evaluate the use of animal and plant protein, in combination with Glucosamine source for Asian Catfish, Clarias batrachus (av. wt. 2.2+0.009 to 2.6+0.03 g). This study was performed to evaluate the effect on fish growth performance by replacing animal protein with vegetable protein sources. In experiment, six (37.40 to 43.52 % crude protein, 16.15 to 16.76 kJ/g energy, and crude lipid 3.33 to 6.69%) practical diets were formulated. The animal and plant protein component of the diets was progressively added with glucosamine 0.5, 5.0 and 10.0% with fish meal, silkworm pupae, soybean meal and casein (F

Length–weight relationship and growth performance of different life stages of hatchery‐produced magur,Clarias magur(Hamilton, 1822)

“…Furthermore, salinity affects the growth and survival of the magur fingerlings; growth rate was directly affected by increasing salinity concentration (Sahoo, Giri, Maharathi, & Sahu, ; Sarma, Prabakaran, Krishnan, Grinson, & Kumar, ). The animal protein diet fed juveniles of C. batrachus attained the body weight of 12.5 g than the plant protein diet (Chowdhary et al, ). All reported studies had both lower or similar body length and weight as compared to the present findings which strongly suggest that the length–weight relation of the present study can be used to assess the growth of C. magur in captive and wild condition.…”

Growth responses on major replacement of animal protein with plant protein and graded levels of dietary supplement amino sugar, glucosamine in threatened Magur (Clarias batrachus, Linnaeus, 1758) fry

“…Soybean products as dietary protein source has been reported to affect the growth and feed utilization of many fish species including channel catfish [46,47], tilapia [24,48], rainbow trout [49,66,68,69], red drum [67,70], seabream [71], Asian catfish [27], cobia [72] and cuneate drum [73]. Amongst the animal proteins, fish meal, meat-meal, goat liver, fish and poultry offal's used as fish diet in case of catfishes particularly in C. batrachus, fish meal has always been considered to perform better in terms of survival, growth and general well-being [74,75,76,77].…”

“…Hence, the dietary requirement of protein is different in various fish species [20,21,22,23,24] reported that partial replacement of FM protein with SBM protein in tilapia diet did not compromise growth of the fish. Substitution of various soy products have shown better growth in many fishes including catfishes [8,25,26,27]. Recently, Sarowar et al [28] have studied the impacts of different diets on survival and growth in C. batrachus grow-outs.…”
