The stockfish industry can save millions if fish are handled correctly, resulting in less mucoso. After three years of research, fishermen are being warned to avoid storing gutted fish in seawater. Mucoso is a condition where the fish meat dissolves and becomes gelatinous after rehydration, resulting in a considerably lower quality and therefore lower price. The industry itself estimates that mucoso causes annual loses of around NOK 40 million. Nofima Fiskeriforskning has just...

Alltech, the global biotechnology company based in Jessamine County, made its name by producing food additives for cows, horses, swine, poultry and dogs. But the company hopes to take its knowledge of land animals and see whether the same all-natural products can benefit fish and shrimp raised by man around the world. A year ago, Alltech, the corporate sponsor for the 2010 FEI World Equestrian Games in Kentucky, opened a $1 million aquaculture center up the road from its...

By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. The last fish you ate probably came from the Bering Sea. But during this century, the sea’s rich food web—stretching from Alaska to Russia—could fray as algae adapt to greenhouse conditions. “All the fish that ends up in McDonald’s, fish sandwiches—that’s all Bering Sea fish,” said USC marine ecologist Dave Hutchins,...

Wild-captured Arctic charr farmed at land-based aquaculture facilities grow better if light conditions are adapted to suit winter, new research on environmentally-friendly aquaculture shows. It is normal practice to provide farmed fish continual light so they grow as rapidly as possible. However, wild-captured Arctic charr have adapted to living in arctic conditions with little access to food in winter. As a result, scientists have tested if a period of darkness in winter can...

Aquaculture is the farming of sea creatures for human consumption. It is done in ponds and adjacent to the sea. Shrimp aquaculture has expanded the fastest over the past two decades in Asia and Latin America. It tops the list of favourite sea food. It is important that you know the consequences of eating farmed shrimp. By the time a shrimp arrives in the market, it has been injected with antibiotics, doused in pesticides, and fed chemical-laden food. Shrimp farms are often dirty,...

As countries from around the world met in Bali, Indonesia recently to thrash out a new framework on fighting global warming, the fishing community there is adapting to the looming impact of climate change. Many are turning away from fishing to a small but innovative scheme aimed at reviving the tropical island’s coral reef, which is threatened by rising temperatures and over-exploitation. The scheme, run by environment group WWF, encourages people to give up damaging fishing...

European collaboration will provide answers about which welfare actions can provide good profitability for the aquaculture industry. A group of scientists from six European countries will develop models that will provide answers about the relationships and consequences if the regulating framework for fish welfare changes. With four selected indicators (mortality, fin damages, deviation in feed intake and changes in CO2) as a starting point, the group will look at biological factors...

Old fashioned use of fish waste as fertiliser has provided the inspiration for a win-win project in the north, with waste from the shrimp industry proving to be a first-class ecological fertiliser. "In the old days, people used fish waste as fertiliser and that's where we got the idea," says Halgeir Jakobsen, potato producer, Ottar Board Member and General Manager of Tromspotet. Ottar is the organisation for North Norwegian potato growers. The organisation is...

How has it been handled before it arrived at the shop? Work is now underway so the fish's history can be traced from the seafood counter back to the boat. As consumers, we want information about the products we buy or, at the very least, to know that it is possible to find out how it has been processed. To achieve this, product information must be forwarded between all the companies from the catch via processors and wholesalers until it is finally on the shop shelf. This...

Researchers at NIFES (National Institute of Nutrition and Seafood Research) have demonstrated that mercury accumulates in cod fillets when the fish is fed feed containing methyl mercury. The elimination rate of the accumulated mercury was relatively slow. Research results indicate that about 40 % of the mercury was transferred from feed to fillet. What is methyl mercury? Mercury exists in several different chemical forms in nature. The most common form and...

Several importers have turned their backs on Vietnam’s black tiger shrimp, while shifting to purchase white shrimp (Peneus Vannamei) which have ‘softer prices’. Tran Thi Mieng, Deputy Director of the Planning and Investment Department under the Ministry of Agriculture and Rural Development (MARD), said that Vietnam’s black tiger shrimp now has a very strong competitor, white shrimp. At several international trade fairs, importers canceled the orders on importing Vietnam’s black...

Researchers at the Universitat Jaume I (UJI) and the Spanish Research Council (CSIC) have patented an innovative method to remove organic pollutants, such as pesticide residues, from bivalve molluscs. The new technique increases the rate of removal of organic compounds by a factor of two or, depending on the type of pollutant, even four with respect to other methods used to date. Bivalve molluscs (mussels, oysters, clams and cockles, among others) obtain their food by filtering sea water...

A compound found in oil-rich fish such as salmon reshaped the blood lipid profiles of volunteers in an Agricultural Research Service-led study. Research chemist Darshan S. Kelley of the ARS Western Human Nutrition Research Center in Davis, Calif., and federal and university co-investigators conducted the study of DHA, or docosahexaenoic acid, a polyunsaturated fatty acid thought to improve cardiovascular health. The research, reported earlier this year in the American Journal of...

A review of problems and perspectives Fish species that have external fertilization can be reproduced by induced parthenogenesis to produce homozygous clones. The nuclear content of either the sperm or egg is destroyed by UV or gamma irradiation, and the treated gamete is then fused with an untreated egg or sperm to form a haploid embryo. This is subsequently made diploid by physical inhibition of the first cell division. The resulting individual is a so-called doubled...

An innovative new heavy duty bird net support system developed by Fusion Marine for salmon farm cages is proving popular with some of Scotland’s leading fish farming companies. Dubbed by Fusion Marine as the ‘hamster wheel’ because of its shape, the system offers several advantages over conventional tripod bird net supports. The broad diameter of the ‘hamster wheel’ provides improved support for protective anti-predator netting by holding the shape better and...

In the latest issue of Science, the leading American research journal, scientists from IMR and the University of Bergen together with colleagues across Europe, draw attention to the evolutionary effects of fishing. The article presented in the journal’s Policy Forum emphasizes that fisheries management should consider the evolutionary consequences of fishing, and discusses how evolutionary changes might influence, for example, recruitment processes or pre-cautionary reference points. In...

Prawn shells have the potential to do a lot more than create a fearsome smell in the garbage bin, with a UNSW food science researcher developing a new technique for extracting a powerful antioxidant found in one of Australia’s favourite seafood snacks. The antioxidant is called astaxanthin. It’s the pigment which gives cooked prawns their red colour but is almost all contained in the shells and heads which are thrown away. Antioxidants can play an important role in protecting cells in...

From this study, and for the superiority of th 3 rd treatment, it could be concluded that the fish – cum – duck integration system of production is important in producing meat duck and Nile tilapia fish under semi-intensive production system in earthen ponds. But it may gave attention to moderate stocking rate of ducks (125 - 250 duck / feddan) on fish ponds to safe water quality, particularly at low stocking rate of fish, as in the present study (16.8 thousand fry of 4 – 5 g / feddan)....

"An extremely good product." That is the chefs' verdict after testing fillet of cod processed a short time after the fish was taken from the net cage. The test involved cod caught in the wild which had been fed for three months. "This is the type of fillet we want on our menu," says Magnus Heggman, chef at Store Norske Fiskekompani restaurant in Tromsø. "The results are very positive. We now want to test this with a large quantity of...
