Replacement of fish meal with poultry by-product meal in artificial feeds of juvenile tiger grouper, Epinephelus fuscoguttatus

A 16-week feeding trial was done to evaluate the possibility of replacing fish meal (FM) with poultry by-product meal (PBM) at high inclusion levels in the feeds of juvenile tiger grouper, Epinephelus fuscoguttatus. Four isoproteic (50%) and isolipidic (13 %) test feeds were formulated and fed to tr...

Fisheries. Angling A 16-week feeding trial was done to evaluate the possibility of replacing fish meal (FM) with poultry by-product meal (PBM) at high inclusion levels in the feeds of juvenile tiger grouper, Epinephelus fuscoguttatus. Four isoproteic (50%) and isolipidic (13 %) test feeds were formulated and fed to triplicate groups of experimental fish. The control feed was formulated with 100 % local FM (PBM 0) and three other feeds with inclusion levels of PBM 50, 75, and 100 %. Fish with mean body weight of 26.4Â±0.2 g were randomly put into groups of 30 fish in cylindrical mesh cages placed in a 150-ton high density polyethylene (HDPE) tank. Feeding was done close to apparent satiation level, twice daily at 08:00 and 16:00 hours. Growth of fish fed PBM 0 and TF were significantly lower (P<0.05) to those fed with PBM 50, 75 and 100. Weight gain of juveniles ranged from 233 to 338 % at the end of feeding trial. The best feed conversion ratio (FCR) was achieved in PBM 50 (1.1), followed by PBM 100 (1.2), PBM 75 (1.3), and PBM 0 (2.0). Feeding with trash fish had resulted in significantly poorer FCR of 6.6. Survival were not significantly different (P>0.05) among all treatments. Apparent digestibility coefficients (ADCs) for dry matter were not Significantly different among dietary treatments, ranging from 58.7Â±2.03 % to 62.42Â± 0.81 %. ADCs for crude protein were Significantly different (P<0.05) among the dietary treatments except for PBM 50 and 75(87.06Â±0.94 % and 85.85Â±0.12 %, respectively) and the values were decreasing for PBM 100 (74.47Â±3.13 %) followed by PBM 0 (73.37Â±3.42 %). ADCs for crude lipid in PBM 100 shows a significantly lower (P<0.05) value compared with PBM 0, 50 and 75 (84.32Â±0.39 %, 87.00Â±0.32 %, 87.05Â±0.52 % and 84.32Â±0.65 %, respectively). Whole body proximate compositions, body indices and haematological parameters were not affected by dietary composition. The basic cost analysis revealed that a combination of 50 % PBM and FM gives the more cost effective result. The present study shows that PBM is an excellent alternative protein source for the tiger grouper juveniles. 2011 Thesis https://eprints.ums.edu.my/id/eprint/11573/ https://eprints.ums.edu.my/id/eprint/11573/1/mt0000000631.pdf text en public masters Universiti Malaysia Sabah Borneo Marine Research Institute
