While the European agricultural industry is a heavy consumer of genetically modified products - largely in animal feed - the industry is restricted in what it can grow, writes Chris Harris, TheFishSite senior editor.
Increasing consumer awareness to unsustainable aquaculture practices have made the prospect of organic aquaculture both environmentally and economically fruitful, but strict standards make this goal difficult to achieve. As the US considers by-passing this obs…
Aquaculture is often condemned by many lobby groups because it uses about 43 percent of global fish meal production and 85 percent of fish oil, writes Simon Wilkinson for the Network of Aquaculture Centres in Asia Pacific (NACA).
Grouper farming, especially in Southeast Asia, is still heavily dependent on feeding with trash fish, say Rossita Shapawi, Saleem Mustafa and Wing-Keong Ng of the Network of Aquaculture Centres in Asia-Pacific.
The probiotic bacillus highly increase thegrowth performances and feeding efficiency in Acipenser nudiventris larvae says a report by H. Jafaryan and A. Bagheri of the Department of Fisheries, Gorgan University of Agricultural Sciences and Natural, and R. Asad…
The main ingredients of feeds for farmed carnivorous fish species are fishmeal and fish oil, at levels of about 25 percent and 30 percent, respectively, according to a new report, called Towards Sustainable Aquaculture in Europe.
The use of plant proteins in fish diets is having an increasing effect on global demand and supplies of grains and oilseeds, says R.W. Hardy, University of Idaho, Aquaculture Research Institute.
By Richard D. Miles and Frank A. Chapman 2. Aquaculture feeds characteristically contain a higher percent of protein than feeds used in agriculture for poultry, swine, and beef.
By Mississippi State University Extension Service. Nutrient requirements and feeding characteristics of channel catfish have been extensively researched. This research has provided the basis for the formulation of efficient, economical diets and for the develo…
Gut function and its efficiency is one of the keys to successful commercial production of fish species. TheFishSite Editor, Jane Jordan, looks at a paper by John Sweetman, Arkadios Dimitroglou, Simon Davies and Silvia Torrecillas on gut morphology and how a he…

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.
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 Jeffrey M. Hinshaw, North Carolina State University and published by the Southern Regional Agricultural Center and the Texas Aquaculture Extension Service.
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 …
