“…They are also hardy and tolerant to a wide range of stressful environmental conditions (Nwani et al, 2015). They are widely cultured in freshwater ponds because of their ease in reproduction, high growth rate, tolerance to high density culture conditions, resistance to diseases, good flesh quality and ability to accept a wide variety of feed (Nyina-wamwiza et al, 2007;Khan and Abidi, 2011;Chor et al, 2013). C. gariepinus with an average weight of 520±25 g/fish were acclimatized to experimental conditions for seven days in concrete tanks (5×10×1 m).…”

This study was conducted to investigate the effects of replacing commercial feed with vinegar-immersed poultry viscera on growth performance, physiological status and bacterial load of the catfish, Clarias gariepinus. Fish were fed on a commercial diet (T1), poultry viscera (T2) and poultry viscera immersed in commercial vinegar (T3). Catfish with an average body weight of 520g were stocked in circular fiberglass tanks each of 2 m 3 water volume for 98 days. Water quality parameters, growth performance, feed utilization, flesh composition, serum analysis and bacterial load of feed, water and fish, were measured. Ammonia content in rearing water decreased significantly in T3 compared to T2. There were not any significant differences detected (P>0.05) in survival and growth performance, while significant (P≤0.05) differences in feed utilization and wholebody composition were detected among treatments. The quality indices of fish in terms of flesh composition were in favor of T3. A decrease in the serum's total protein and albumin and an increase in the serum's globulin and cholesterol levels were observed when fish was fed on poultry viscera only. Pathogenic bacterial load in feed, rearing water and fish intestine were at their lowest limit in T3. This study shows that C. gariepinus can feed on poultry viscera immersed in commercial vinegar as an alternative feedstuff source to commercial high-priced feed. The ecological impacts of treating environmentally hazardous by-products, like poultry viscera and converting it to a high value by-product are a matter of interest for both aquaculurists and environmentalists alike. More research work is needed to take advantage of the current results in a commercially applicable scale. Egyptians dating back to ancient times consider catfish one of the most favorite fish types. Many images of Catfish appeared on the walls of ancient Pharaonic temples. In 2015, the total catfish production in Egypt was 37,914 tons/year, of which 7,455 tons/year were obtained from aquaculture (GAFRD, 2015). African Catfish require about 40% CP in their diet and the best results have been achieved with crude protein value ranging from 35 to 50% for all African Catfish species (Adebayo and Quadri, 2005). Nutrition is one of the most important factors in fish farming because it contributes to up to 50% of fish production costs (Omoruwou and Edema, 2011). Feeding is one of the major constraints facing aquaculture. The importance of fish meals in the production of animal feeds cannot be disputed, but forms the highest cost and therefore raises the price of the feed exponentially (Olaniyi and Salau, 2013). The feeding can be harmful to the fish's health and may cause a remarkable drop in water quality, reduce growth, decrease feed utilization and increase susceptibility to infection (Priestley et al., 2006). Therefore, there is the need to balance between rapid fish growth and the optimum use of the supplemented feed in order to be economically viable and for the fish to be in good health (Wuraola1 and ...

“…Among the rendered animal protein ingredients, PBM has been demonstrated a quality dietary fish meal substitute for carnivorous fishes, such as largemouth bass Micropterus salmoides (Tidwell, Coyle, Bright, & Yasharian, ), cuneate drum Nibea miichthioides (Wang, Guo, Bureau, & Cui, ), humpback grouper Cromileptes altivelis (Shapawi, Ng, & Mustafa, ), malabar grouper Epinephelus malabaricus (Li et al., ), cobia Rachycentron canadum (Zhou, Zhao, Li, Wang, & Wang, ), Florida pompano Trachinotus carolinus (Rossi & Davis, ) and Japanese sea bass Lateolabrax japonicus (Wang, Wang, Ji, Han, & Li, ). The potential of feather meal to replace dietary fish meal has been evaluated in chinook salmon Oncorhynchus tshawytscha (Fowler, ), Japanese flounder Paralichthys olivaceus (Kikuchi, Furuta, & Honda, ), African catfish Clarias gariepinus (Chor, Lim, & Shapawi, ) and tench Tinca tinca (González‐Rodríguez, Celada, Carral, Sáez‐Royuela, & Fuertes, ). Compared with PBM, FEM is a poor alternative ingredient of fish meal, and high feather meal inclusion results in growth decline of cuneate drum (Wang et al., ).…”

An 8-week feeding trial was conducted to evaluate the potential of replacing fish meal with poultry by-product meal (PBM) and feather meal (FEM) in giant croaker (Nibea japonica) diet. The control diet (C) contained 400 g/kg fish meal, and 20%, 40%, 60% and 80% of the fish meal in diet C was replaced by a blend of PBM and FEM (PBM: FEM = 7:3) in diets B20, B40, B60 and B80, respectively. The weight gain and feed intake of fish fed diet C did not differ from those of fish fed diets B20 and B40 (p > .05), but were higher than those of fish fed diets B60 and B80 (p < .05). Phosphorus retention efficiency was lower in fish fed diets C, B20 and B40 than in fish fed diets R60 and R80 (p < .05). No significant differences were found in feed conversion ratio, nitrogen retention efficiency, condition factor, hepatosomatic index, body composition and nitrogen waste among the treatments (p > .05). Ratio of fish meal consumption to fish production linearly declined with the decrease in dietary fish meal level. This study indicates that dietary fish meal for giant croaker could be reduced to 240 g/kg by inclusion of the blend of PBM and FEM.

“…Several studies exploring the potential of FeM as a substitute for fishmeal in practical fish diets reported a decline in feed intake with increasing levels of dietary FeM(Arunlertaree & Rakyuttithamkul, 2006;Chor, Lim, & Shapawi, 2013;Suloma et al, 2014). Those investigators partially attributed this depression in feed intake and, thus, in growth performance, to an impairment of diet palatability in high-FeM diets caused by the pungent smell of the ingredient(Arunlertaree & Rakyuttithamkul, 2006;Chor et al, 2013;Suloma et al, 2014). It appears plausible that in our study, similar palatability issues negatively affected the voluntary feed intake and growth performances of fish fed the high-FeM and PTFeM diets.The scorched smell detected in FeM1 and PTFeM1 may also indicate heat damage of the amino acid content in the ingredients.…”

A growth trial followed by a digestibility trial were conducted to assess the bioavailability of arginine (Arg) and amino acid digestibility of two feather meals (FeMs) and their pre‐treated counterparts (PTFeMs). Two FeMs, identified as FeM1 and FeM2, were incubated in 200% distilled water (%FeM w/w), with 0.05% of Savinase® 16L (%FeM v/w) and 2% sodium sulphite (%FeM w/w) at 55ºC for 24 hr in a shaking incubator to produce PTFeM1 and PTFeM2 respectively. A basal diet, highly deficient in Arg (12.0 g/kg Arg) was formulated and 10 other diets were formulated to contain 13.5 or 15.0 g/kg Arg by adding increasing amounts of L‐Arg, FeMs or PTFeMs. The experimental diets were fed for 8 weeks using a standard protocol. At 13.5 g/kg Arg, the PTFeMs supported 10.5% to 11.5% higher growth rates (p < 0.05) than their untreated counterparts. The diets formulated with PTFeMs presented 3.5%–4.5% and 2.7%–5.9% higher (p < 0.05) apparent digestibility coefficients of protein when compared to the diets containing the FeM counterparts at 13.5 and 15.0 g/kg Arg respectively. The results from this study demonstrate the potential of the pre‐treatment to improve the nutritive value of FeMs in rainbow trout.
