The high cost of fish feed has affected the culturing tilapias and sharptooth catfish in Africa. However, Africa is well endowed with terrestrial insects that can potentially replace fishmeal diets fish. In this paper, nutritional index, availability, selected insect meals are compared. SOLVER function Excel was used to formulate least-cost Musca domestica, Gryllotalpa africana, Schistocerca gr...

Producing organic fish diets requires that the use of both fishmeal and fish oil (FO) be minimized and replaced by sustainable, organic sources. The purpose of the present study was to replace FO with organic oils and evaluate the effects on feed intake, feed conversion ratio (FCR), daily specific growth rate (SGR) and nutrient digestibility in diets in which fishmeal protein was partly substit...

This study presents the availability of fish feed ingredients and their nutritive value in Lakshmipur region, southern Bangladesh considering the presence of large number of fish farms in those areas. A survey was conducted to collect the ingredients from the local markets and fish farms of the area. A range of commonly used feed ingredients for fish farming was available in the markets that in...

The strong growth of aquaculture in Senegal has led to a significant use fishmeal, which is becoming rarified and expensive. In order make the feed accessible small-scale producers, it became necessary find substitute for fish meal mainly used feeds, due its high content balanced proteins. Therefore, three feeds were formulated rearing comparison an industrial feed. study was conducted 45 days ...

Clostridium perfringens can induce necrotic enteritis of chickens, which causes large economic losses every year. Bacillus licheniformis, a probiotic, can inhibit the growth of pathogenic bacteria such as Clostridium perfringens, thereby improving the health status of chickens. However, from a microbial ecology perspective, the mechanisms by which alterations to the gut microbiota improve healt...

Yeast is frequently used as a probiotic in aquaculture with the potential to substitute for antibiotics. In this study, the involvement and extent to which the viability of yeast cells and thus the secretory metabolites released from the yeast contribute to effects of baker's yeast was investigated in Nile tilapia. No yeast, live yeast or heat-inactivated baker's yeast were added to basal diets...

In the context of limited marine resources, the exponential growth of aquaculture requires the substitution of fish oil and fishmeal, the traditional components of fish feeds by terrestrial plant ingredients. High levels of such substitution are known to negatively impact fish performance such as growth and survival in rainbow trout (Oncorhynchus mykiss) as in other salmonids. In this respect, ...

Abstract In Europe, turbot aquaculture has a high potential for sustainable production, but the low tolerance to fishmeal replacement in diet represents big issue. Therefore, this study investigated effects of more feed formulations on growth and performance, as well nutritional status juvenile recirculating systems. 16-week feeding trial with 20 g turbot, one control containing traditional fis...
