Effect of totally or partially replacing fish meal by alternative protein sources on growth of African catfish Clarias gariepinus (Burchell, 1822) reared in concrete tanks

Abstract

A 12‐week feeding trial was carried out in concrete tanks to examine complete and partial replacement (75%) of fish meal (FM) with poultry by‐product meal (PBM), meat and bone meal (MBM) and soybean meal (SBM) in practical feeds for African catfish Clarias gariepinus. Triplicate groups of fish (initial body weight ranged from 90.33 to 93.93 g fish−1) were fed seven isonitrogenous and isocaloric diets of 20% digestible protein and 300 kcal 100 g−1 of digestible energy. The control contained 25% herring meal, whereas in the other six diets, PBM, MBM and SBM replaced 75% or 100% of the FM. Final body weight (FBW) and specific growth rate (SGR) of the fish fed diets containing PBM (75% and 100%), SBM (75% and 100%) and MBM (75%) were all higher, but not significantly different than those for fish fed the control diet. Replacing 100% of the FM by MBM significantly lowered FBW and SGR. Concerning whole body composition, there were no significant differences in ash and gross energy content of whole‐body among fish; fish fed diets containing PBM‐100% recorded significantly lower protein content compared with the control diet, while fish fed diet SBM‐100% recorded significantly lower moisture content compared with the control diet. Also fish fed diets SBM‐100% and PBM‐75% recorded higher lipid and gross energy contents compared with the control diet. The study revealed that satisfactory growth and feed utilization responses could be achieved through the replacement of FM by PBM, SBM and MBM in the diet of African catfish.

Fontes protéicas vegetais na alimentação da carpa húngara

“…A farinha de carne é fonte de origem animal com grande potencial para a aquicultura, pelo alto nível de proteína (45-55%), menor preço, comparada à farinha de peixe, palatabilidade e equilíbrio de aminoácidos essenciais (GODA et al, 2007). Entretanto, variações na composição, alto teor de gordura e matéria mineral dificultam sua utilização em rações.…”

Responsible Fishmeal Consumption and Alternatives in the Face of Climate Changes

“…Increasing fishmeal cost, irregular supply, decreasing availability, and poor quality of fishmeal have put forward highlighting on its partial or complete substitution with other alternative protein sources (Ramachandran and Ray, 2007). Currently, a lot of studies have been conducted to assess the partial or complete substitution of fishmeal in feed diets for tilapia with less expensive as well as locally available plant and animal protein sources (Fasakin et al, 2005;Borgeson et al, 2006;Gaber, 2006;Goda et al, 2007;Schuchardt et al, 2008;Soltan et al, 2008;Ali et al, 2008;Metwally and El-Gellal, 2009;Mohammad and Abdel-Tawwab, 2011;Labib et al, 2012;Abo-State et al, 2014;Hassan et al, 2015;Labib et al, 2015;Yones and Metwalli, 2015;Sharawya et al, 2016;Al-Asgah et al, 2016;. The review in hands aims to appraise the diverse types of fishmeal substituents and draw attention to the most proper alternatives in fish diets.…”
