By Fiskeriforskning - The quality of extruded fish feed is a complicated interaction between raw material properties and feed processing conditions. Through increased basic understanding Fiskeriforskning is seeking to develop new quality criteria and control p…

By Trine Ytrestyl, AKVAFORSK - This thesis focuses on factors that influence the bioavailability of carotenoids primarily in salmonid fishes. Atlantic cod (Gadus morhua) was used in one experiment to study uptake in a white-fleshed species.

By Fiskeriforskning - Blue whiting (Micromesistius poutassou) is a small, lean cod fish of high importance as rawmaterial for fish meal production in Norway. Fish meal produced from blue whiting generates lower growth and feed efficiency in salmon, halibut and…

From the University of Adelaide - South Australian researchers are unlocking the secrets to faster fish growth rates.

In a new book, The Benefits of Fish Meal in Aquaculture Diets, RD Miles and FA Chapman, from the University of Florida, explain the value of fishmeal in feeds for fish and shrimp.

Since cultured catfish get only a small portion of their food nutrients naturally, they must be fed a complete feed, according to scientists from Mississippi State University.

By the Mississippi State University - Todays catfish producer feeds a nutritionallycomplete diet that has all the necessary nutrients at the right levels and the energy the fish need in a water-stable, readily digestible form. Producers must feed this kind of …

Given the nutritional value and profile (comparability of amino acids, EFA, and micronutrients) of maggot meal (MM), this study, by Emilie Devic et al, University of Stirling, evaluates strategies for the substitution of fish meal (FM) by MM, different method…

This study by Yukinori Mukai, International Islamic University Malaysia, and Leong Seng Lim, University Malaysia Sabah, examined the retinomotor responses and prey ingestion rates of 10-, 15-, 20- and 30-day-old Asian seabass Lates calcarifer under different l…

The performance of the aquafeed industry in Egypt is not well understood, as the value chain structure has not yet been mapped. This study aims to assess the status of the fish feed sector in Egypt, with an emphasis on: mapping and understanding fish feed valu…

A significant part of the Philippine production is achieved semi-intensively, or even intensively, which creates a demand for supplemental feed. Optimizing of the feeding and nutrition of milkfish is therefore of great interest. Dietary potassium diformate (KD…

Taurine is not considered an essential amino acid for fish, but many studies indicated that it is conditionally essential, especially if fish are fed plant protein-based diets. In response to these studies, Abdel-Fattah M. El-Sayed, Alexandria University, Egyp…
