Evaluation of Growth Performance in Mugil cephalus l. Juveniles Fed Diets Incorporated with Fermented Plant Feedstuffs Replacing Fishmeal or Diets Supplemented with Fish Gut Bacteria

Growth performance, digestive enzyme activity, non‐specific immune response and stress enzyme status in early stages of grey mullet reared in a biofloc system

“…This may be attributed to higher conversion of biofloc nutrient to fish carcass nutrient, as shown by lower FCR and higher PER in this group (De et al, 2015; Ghoshal & Kundu, 2012). The same results were observed by De et al, (2018) after feeding grey mullet with bacterial supplemented diet. There was no significant difference in ash content of fish between the biofloc and control treatment observed by Romano et al, (2018) and Long et al, (2015).…”

Effects of dietary protein on growth performance, nutrient utilization, digestive enzymes and physiological status of grey mullet,Mugil cephalusL. fingerlings reared in inland saline water

“…Alterations in blood haematological parameters express the adaptability of fish to different dietary compositions and environmental conditions which reflects the immunological potential of fish (Bahmami, Kazemi, & Donskaya, ; De et al, ). In this study, the RBC count is positively related to the dietary protein level, which may be due to release of erythrocytes from spleen as dietary protein does affect spleen activity (Abdel‐Tawwab, ).…”

“…This could be due to that fish try to maximize the utilization of available protein by increasing the digestive capacity. Further, this also explains the good utilization capacity of plant protein‐based diet by grey mullet fingerlings as previously demonstrated by Jana et al (), Gisbert et al (), Kalla et al () and De et al () in the same species. The increasing protease activity might have driven maximum protein synthesis in optimum protein level as supported by the highest RNA:DNA ratio and growth.…”

“…Taking advantage of the feeding preference of grey mullets towards benthic and detritus microalgae, artificial low-cost feeds can be formulated using alternate plant protein source ingredients (De, Ghoshal, Biswas, Mukherjee, & Kumar, 2018;El-Dahhar, Salama, Moustafa, & Elmorshedy, 2014;Gisbert, Mozanzadeh, Kotzamanis, & Estévez, 2016;Jana, Sudesh, Garg, Sabhlok, & Bhatnagar, 2012;Kalla, Garg, Kaushik, Arasu, & Dinodia, 2003;Wassef, El Masry, & Mikhail, 2001). In this context, leaf meal or plant protein sources can be the cheapest source of protein in the fish diet, which is often economically and environmentally sustainable (Adewolu, Adeniji, & Adejobi, 2008).…”

Sustainable Aquafeed with Marine Periphyton to Reduce Production Costs of Grey Mullet, Mugil cephalus

“…The production of aquatic animals for human consumption is increasing rapidly at an annual rate of 5.3% y −1 (2001-2018), surpassing capture fisheries [1]. Consequently, reliance on formulated feed is also rising [2] and may reach a production yield of over 58 million tons by 2025 [3]. Since aquafeed comprises 50-75% of total fish production costs [4], the sustainability of feed ingredients is of significant concern.…”
