By comparison with the vast sums of money involved in high-tech salmon farming the battle against parasites might seem like small fry, yet sea lice continue to elude modern eradication methods. Adam Anson, reporting for TheFishSite, finds out where the war is …
Saving water is an environmentally responsible goal, especially in the southeastern parts of the country, where droughts are fairly frequent, writes Sharon Durham, Agricultural Research Service Information Staff.
The idea of ethical food is promoted in almost every modern supermarket, but when it comes to producing, catching and eating fish, deciding what ethical means isn't as easy as it seems, writes Adam Anson, reporting for TheFishSite.
Born from the abstract philosophy of ecocentric ideals, aquaponics has emerged at the very frontier of agricultural technology. Yet, many years after the modern concept was first realised it has yet to receive the commercial recognition that might unlock its t…
In this age of economic recession and ever worsening third world food crisis, it is increasingly important that developing countries find profitable industries for their sustained independence. As a source of both food and finance, it is not difficult to see w…
Fish farming is very efficient in terms of the conversion of protein, which means an important ecological advantage in light of the sustainability of fish feed resources, says a report in the CONSENSUS brochure: 'Towards Sustainable Aquaculture in Europe'.
In the third quarter of the year, fishmeal production was characterized by very limited catches, a normal feature for this period of the year, reports FAO Globefish.
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.
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 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…
