Meat and Bone Meal as Partial Substitute for Fish Meal in Nursery Diet for Giant Freshwater Prawn, Macrobrachium rosenbergii (de Man)

Abstract

An experiment was conducted for 60 d in a recirculatory system consisting of 20 glass aquariums (each of size 41 × 41 × 46 cm) to evaluate meat and bone meal (MBM) as partial replacement for fish meal (FM) in Macrobrachium rosenbergii postlarvae (PLs) with a view to develop an inexpensive nursery diet. Three nursery diets were formulated to contain 32% protein and to be as isoenergetic as possible. FM in these diets was progressively replaced with MBM (Diet 1 contained 25% FM and 14% MBM, Diet 2 contained 20% FM and 20% MBM, and Diet 3 contained 15% FM and 26% MBM). Inclusion levels of mustard oilcake and sesame meal in diets were kept fixed at 10%. A commercial shrimp nursery diet (30% protein) from Saudi Bangla Fish Feed Ltd., Mymensingh, was used as the reference diet (Diet 4). Each treatment had three replicates. PLs of M. rosenbergii (26 ± 0.02 mg) were stocked at the rate of 60 PLs (1 PL/L) in each aquarium. At the beginning, PLs were fed three times daily at a rate of 20% of the body weight and it was gradually reduced to 10% at Day 30. The ranges of water quality parameters in the system were as follows: temperature, 27–29 C; dissolved oxygen, 6.5–8.4 mg/L; pH, 6.8–8.3; and total ammonia, 0.01–0.15 mg/L. The result of the study showed that there was no significant difference (P > 0.05) between the weight gains of PLs fed Diet 1 (containing 14% MBM) and Diet 4 (reference diet) but was significantly higher than other dietary groups containing higher levels of MBM. Diets 1 and 4 showed significantly lower (P < 0.05) apparent food conversion ratios (1.74 and 1.73, respectively). The survival (%) of PLs ranged between 62 and 76% with PLs fed Diets 1 and 4 showing significantly higher (P < 0.05) survival. The result of the study demonstrated that the MBM could be included at 14% level in a nursery diet, and a diet containing 25% FM, 14% MBM, 10% sesame meal, and 10% mustard oilcake may be recommended for profitable production of PLs of M. rosenbergii.

Effects of fish meal replacement by meat and bone meal supplemented with garlic (Allium sativum) powder on biological indices, feeding, muscle composition, fatty acid and amino acid profiles of whiteleg shrimp (Litopenaeus vannamei)

“…In this way, the replacement of FM by other protein sources is an important action towards the sustainability of whiteleg shrimp production. Among potential alternative protein sources, MBM has been suitably formulated in whiteleg shrimp diets (Forster et al, 2003;Hernández et al, 2008;Tan et al, 2005) and giant freshwater prawn (Arshad Hossain & Farzana Islam, 2007). Recently, the amount of fishmeal in whiteleg shrimp diet could be declined from 250 g/kg to 100 g/kg without affecting the growth performance (Xie, Niu, Zhou, Liu, & Tian, 2018).…”

“…When garlic was supplemented to the diets, the level of replacement increased up to 50% (227 g/kg FM in diet) without decreasing growth performance. Therefore, the result of some studies who applied less than 300 g/kg FM as a control diet can be called into question (Arshad Hossain & Farzana Islam, 2007;Forster et al, 2003;Xie et al, 2018;Ye, Wang, Li, Sun, & Liu, 2011). However, some other researchers considered this point and thus formulated a diet for shrimp with higher than 400 g/kg FM as a control diet (Hernández et al, 2008;Tan et al, 2005).…”

“…There are some studies that applied MBM in the diet of whiteleg shrimp ( Litopenaeus vannamei ) (Forster, Dominy, Obaldo, & Tacon, ; Hernández, Olvera‐Novoa, Aguilar‐Vejar, González‐Rodríguez, & de la Parra, ; Tan et al, ) and giant freshwater prawn ( Macrobrachium rosenbergii ) (Arshad Hossain & Farzana Islam, ). Foster et al () tested three different MBM so that they could replace 75% of FM in shrimp diet by MBM (530 g/kg protein, 170 g/kg fat and 190 g/kg ash) without impairing growth performance.…”

Optimal Replacement of Soybean Meal with Fermented Palm Kernel Meal as Protein Source in a Fish Meal-Soybean Meal-Based Diet of Sex Reversed Red Tilapia (Oreochromis niloticus × O. mossambicus)

“…Similar to other economic fish species, the cost of main protein ingredients (mainly fish meal) for formulating the pellet diets is continuously increasing [4]. Therefore, the protein sources from plant by-products have been used to replace fish meal in fish diets [5,6], as have low-cost animal by-products [7,8].…”
