By Kiotech and CEFAS. After laboratory tests, the first commercial trials using pheromone-based fish feeding attractants have proved to be very encouraging.

By Richard D. Miles and Frank A. Chapman, University of Florida - Aquaculture feeds characteristically contain a higher percent of protein than feeds used in agriculture for poultry, swine, and beef. A typical commercial production diet formulated for tilapia …

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…

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.

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

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 Edwin H. Robinson, Menghe H. Li, and Bruce B. Manning, Thad Cochran National Warmwater Aquaculture Center and published by the Mississippi Agriculture and Forestry Experiment Station - This is the 2nd revision of this report on the status of catfish nutriti…

By Mississippi State University - Since feed is the most expensive part of catfish production, feeding a nutritious feed that converts efficiently and promotesgrowth without hurting water quality should increase production and profit.

By Fiskeriforskning - Analyses done by Fiskeriforskning show that the use of natural antioxidants in fish oil and fishmeal works almost as good as the synthetic ones that are being used by feed manufacturers today.

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…

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…

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…

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…
