Evaluation of the Efficacy of Fermented By-product of Mushroom, Pleurotus ostreatus, as a Fish Meal Replacer in Juvenile Amur Catfish, Silurus asotus: Effects on Growth, Serological Characteristics and Immune Responses

Abstract

The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus asotus. A total number of 225 fish averaging 5.7±0.1 g (mean±standard deviation) were fed one of the five experimental diets formulated to replace FM with FBPM at 0%, 5%, 10%, 20%, and 30% (FBPM0, FBPM5, FBPM10, FBPM20, and FBPM30, respectively). At the end of eight weeks of the experiment, average weight gain (WG) of fish fed FBPM0 or FBPM5 were significantly higher than those of fish fed FBPM20 or FBPM30 diets (p<0.05). However, there was no significant differences in WG among the fish fed FBPM0, FBPM5 or FBPM10, and between fish fed FBPM10 or FBPM20, and also between those fed FBPM20 or FBPM30 diets. Lysozyme activity of fish fed FBPM0 or FBPM5 were significantly higher than those of fish fed FBPM10, FBPM20 or FBPM30 diets (p<0.05). The chemiluminescent response of fish fed FBPM5 was significantly higher than those of fish fed FBPM0, FBPM20 or FBPM30 diets (p<0.05). Broken line regression analysis of WG suggested that the maximal dietary inclusion level for FBPM as a FM replacer could be 6.3% without any adverse effects on whole body composition and on serological characteristics. Therefore, these results may indicate that the maximal dietary inclusion level of FBPM as a FM replacer could be 6.3% in juvenile Amur catfish.

“…Similar to the LYZ result, post challenge marron that was fed FPBM revealed significantly higher PR than the pre challenge groups. In agreement with some previous studies (Kumar et al, 2014;Elshopakey et al, 2018), the present results proved the immunomodulatory effects of FPBM on marron by elevating the level of THC, DHC, PR, and LYZ.…”

Nephroprotective Effect of Pleurotus ostreatus and Agaricus bisporus Extracts and Carvedilol on Ethylene Glycol-Induced Urolithiasis: Roles of NF-κB, p53, Bcl-2, Bax and Bak

“…Mushrooms have long had a role as a branch of alternative medicine [ 30 ] and as functional diets [ 31 ]. In particular, Pleurotus ostreatus ( P. ostreatus ) has been confirmed to have medicinal effects, spanning anti-carcinogenic, anti-hypercholesterolemic, anti-inflammatory, anti-oxidative, immuno-stimulating and anti-viral properties and ability to regulate blood lipid and glucose levels [ 32 , 33 , 34 , 35 , 36 ]. Another important medicinal mushroom is Agaricus bisporus ( A. bisporus ), which has been demonstrated to possess various valuable biological properties including anti-aromatase, anti-inflammatory, antitumor, antimicrobial, antioxidant and immunomodulatory activities [ 37 , 38 , 39 , 40 ].…”

Efficacy of insect larval meal to replace fish meal in juvenile barramundi, Lates calcarifer reared in freshwater

“…Aquaculture has become the fastest growing food-producing industry around the world; however, the production efficiency of aquaculture could be further increased through the development of nutritious and costeffective alternatives to traditional and finite marine protein feedstuffs such as fish meal (FM) (Suarez et al 2013;Katya et al 2014). Numerous studies have been carried out to replace or reduce the inclusion level of FM and to identify promising alternative protein sources in aquafeeds.…”

“…Numerous studies have been carried out to replace or reduce the inclusion level of FM and to identify promising alternative protein sources in aquafeeds. Some of the thoroughly investigated ingredients to partially replace FM in fish feed include plant protein sources such as soybean meal, corn gluten meal and soy protein concentrate, by-products of mushroom (Carter and Hauler 2000;Refstie et al 2001;Choi et al 2004;Lim et al 2004;Kim et al 2008;Katya et al 2014) and animal protein sources such as meat and bone meal, blood meal, feather meal, poultry by-product meal and lysine by-product (Bai et al , 1998Lee and Bai 1997a, b). However, least attention has been given to access the use of unconventional but promising feedstuffs such as insect meal in commercial fish feed formulation.…”
