“…Inferior growth performance (weight gain and SGR) of abalone fed the CBM100 diet compared to abalone fed the CBM0 diet in the present study might indicate that an excessive amount of FM substitution with CBM in abalone feed may bring about reduced growth performance. Analogous results were also observed in other studies (Falaye et al, 2011; Kim et al, 2021; Wu, Zhang, et al, 2022) showing that high substitution level of FM with CBM in diets led to the reduced growth performance of fish. This could attribute to the fact that relatively low essential AA (lysine and methionine) content in CBM compared to FM for the growth of aquatic animals could not satisfy dietary needs for their normal growth (Lasekan et al, 2013; Lloyd, 2016; Seong et al, 2015).…”

This study aims to assess the effect of replacing anchovy meal with chicken by‐product meal (CBM) in juvenile abalone (Haliotis discus hannai) feed. Five diets were formulated to contain 0 (CBM0), 25 (CBM25), 50 (CBM 50), 75 (CBM75), and 100% (CBM100) CBM in replacement to 24% fish meal (FM). Dried Saccharina japonica, which is the natural food for this species of abalone was also prepared. Each diet was fed to triplicate groups of abalone. 1260 abalone assigned into eighteen cages were fed for 16 weeks. After the 16‐week feeding trial, 30 abalones from each cage were exposed to air for 24 h, and survival was monitored for 7 days. Results showed that weight gain and specific growth rate of abalone fed the CBM0 (185.4 ± 12.83% and 0.93 ± 0.040%/day, respectively) diet were significantly (p < 0.04 for both) higher than those of abalone fed the CBM100 (139.0 ± 6.36% and 0.78 ± 0.024%/day, respectively) diet. Shell length and width of abalone fed the CBM0 diet were significantly (p < 0.003 and p < 0.02, respectively) longer and wider than those of abalone fed the CBM75 and CBM100 diets. Survival of abalone during the 7‐day post‐observation period after the 24‐h air exposure exhibited no remarkable (p > 0.1 for Log Rank and Wilcoxon tests) difference among all formulated diets according to the analysis of the Kaplan–Meier survival curve. In conclusion, CBM can replace FM up to 50% in an abalone diet without compromising growth performance and survival.

“…Results from other trials on PM in diets for African catfish are mostly in line with the results of the present study. Authors testing up to 100% FM replacement with PM at an absolute level of PM inclusion of 6-47% (versus 56.4% in this study) generally recorded growth reduction and feed conversion impairment at the highest replacement levels in comparison to their control diets [75][76][77][78][79][80][81][82] and recommend FM replacement levels of 65% (30.6% PM inclusion) [82], 56% [80], 40% (17% PM inclusion) [78] and 30% (6.3% PM inclusion) [79]. However, [77] did not find significant differences in growth performance and feed conversion at 75-100% FM replacement (26-34.5% PM inclusion) compared to the FM control diet.…”

Toward Feeds for Circular Multitrophic Food Production Systems: Holistically Evaluating Growth Performance and Nutrient Excretion of African Catfish Fed Fish Meal-Free Diets in Comparison to Nile Tilapia

In aquaponics and circular multitrophic food production systems, dietary protein source, as well as fish species choice, particularly in cases of different nutritional physiology, could be factors affecting excreted nutrient profiles. Accordingly, growth performance, dissolved nutrient accumulation and feces nutrient profiles were evaluated for African catfish (Clarias gariepinus) reared in recirculating aquaculture systems (RAS) and fed single protein source diets based on black soldier fly larvae meal (BSF), poultry by-product meal (PM), poultry blood meal (PBM) and fish meal (FM) and the results were compared to previous findings for Nile tilapia (Oreochromis niloticus). All diets resulted in significantly different growth performances of African catfish, with FM producing the best growth performance, followed by PM, BSF and PBM. PM resulted in the highest soluble reactive phosphorus concentrations (SRP) in the RAS water; whereas, BSF resulted in the highest K, Mg and Cu concentrations. The highest feces nutrient density was recorded for PBM; whereas, FM and PM yielded the lowest feces nutrient density. Comparing African catfish to Nile tilapia revealed that the former showed significantly better growth performance with FM and PM, however, significantly weaker performance with BSF. Although dissolved K accumulation was similar between species across diets, significant differences were recorded for total inorganic nitrogen and SRP production per unit of feed for individual diets. Despite similar feces nutrient profiles, African catfish produce significantly less feces dry matter per unit of feed for each diet compared to Nile tilapia. Findings are discussed regarding their implications for aquafeed development in the context of circular multitrophic food production systems.

This study evaluates the nutrient utilization and growth performance of African catfish (Clarias gariepinus) fed alternative animal protein composite meal for 42 days. The composite meal is composed of feather meal, blood meal, tilapia meal, and maggot meal each in a 25% proportion. Five isonitrogenous diets (T1, T2, T3, T4, and T5) containing 40% crude protein were formulated with the composite meal replacing fish meal at 0% control (T1), 25% (T2), 50% (T3), 75% (T4) and 100%(T5) respectively. The weight gain, protein intake, protein efficiency ratio, and specific growth rate in the 75% and 100% inclusion levels were not significantly different from the control diet. Fish survival ranged between 90-95% with the highest weight gain of 10.57g observed in the 100% inclusion level. The Feed conversion ratio varied between (1.17 and 1.37). The results from growth, feed utilization, and survival levels showed an overall good growth of the fish in the experimental diets, and this indicates that the composite meal is a potential replacement for fish meal in the diets of Clarias gariepinus fingerlings.
