Digestibility of fermented copra meal for fish as plant protein source in the Saline tilapia (Oreochromis niloticus) Seeds

Abstract

Copra meal is an alternative protein source as fish meal in fish feed because the nutritional value is almost the same. However, copra meal has a relatively high crude fiber content, so efforts are needed to reduce crude fiber content through the fermentation process using the microbe Rizopus sp. which produces cellulase enzymes. This study aims to determine the digestibility level of fermented copra meal in feed as a source of vegetable protein in the maintenance of saline tilapia (Oreochromis niloticus) seeds. The research were conducted with the addition of fermented, dried and powdered copra meal to the feed with a concentration of: (A) 0%; (B) 15%; (C) 30% and (D) 45%. The fish were given test feed on a daily basis with a feeding frequency of once per day. The results showed that giving 15% of the fermented copra meal as plant protein source in the feed gave a better total feed digestibility compared to the addition of unfermented copra meal.

Systematic review and meta-analysis of the growth performance and carcass composition of Nile tilapia (Oreochromis niloticus) fed dietary copra meal

“…The method/s used for feed and/or ingredient preparation can affect fish performance. For instance, fermentation of copra meal can increase its efficiency as a fishmeal replacement (Dileep et al, 2021) since the additional fermentation step degrades some of the non-nutritional contents in copra meal, including high dietary fiber (Harlina et al, 2021).…”

“…Additionally, fermented copra was added up to 30% in diets of rohu fingerlings and 14% of rabbitfish ( Siganus javus ) diets 118 without compromising performance and survival. Fermented copra meal at an inclusion rate of 15% in the maintenance diets of tilapia seeds also had higher digestibility than raw copra meal 119 …”

“…Additionally, copra meal hydrolysate, which contains mannan polysaccharide produced by the enzyme mannanase, shows promise as a prebiotic in food and feed applications 9 . The use of fermented copra meal as a plant protein source in fish feed has also been studied 10 . Furthermore, copra meal is being investigated for its potential as a biosorbent in the remediation of heavy metals 11 .…”

“…9 The use of fermented copra meal as a plant protein source in fish feed has also been studied. 10 Furthermore, copra meal is being investigated for its potential as a biosorbent in the remediation of heavy metals. 11 These findings highlight the diverse applications of copra meal and the high value addition possible.…”
