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...

The National Cod Breeding Centre has produced more cod than ever this year - and with 190 families it's virtually a full house at the facility. It's now five years since the National Cod Breeding Centre was established in Tromsø. Production has increased every half-year and a new record has been achieved again this year. "Our aim was to produce 200 families. We managed 190 and we are extremely satisfied", says Atle Mortensen, who heads the National...

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...

Salmon producers, retailers, scientists, environmental groups and others from throughout the world will meet in Chile in December to review new reports about two of the main impacts of salmon aquaculture production: chemical inputs and nutrient loading/carrying capacity. Information in the reports, it is said, will then be used to guide discussions about developing jointly acceptable global standards for salmon aquaculture. A discussion about the socioeconomic costs and benefits of...

An international team of researchers has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming. With fishing pressures high and stock size low, there is already major concern over the current sustainability of cod and other fisheries. The new findings, published in the journal Proceedings of the Royal Society B, show that natural climate change has previously reduced the range of...

If you're depending on farmed salmon for your daily vitamin D quota, you might rethink your strategy. It's a healthy food, but it doesn't contain the bounty of vitamin D many nutritionists count on. New research shows that popular farmed salmon has only a quarter as much vitamin D as wild caught. Although wild salmon doesn't have quite enough vitamin D to meet new suggested medical guidelines, it's a much better bet. The USDA has long claimed that 3.5 ounces of salmon contains...

The King crab can now be eaten without removing the shell if it is handled and prepared right after moulting when the shell is completely soft. The shell and crab can then be consumed once the mouth, stomach, intestine and gills have been removed. Soft-shell crab is an exclusive product at Asian restaurants, and soft-shell crabs can achieve five times the price than the equivalent crab with a hard shell. Taste testing Soft-shell King crabs...

Scientists in northern Tasmania have found that barramundi grow more quickly when fed lupins rather than smaller fish like anchovies. Professor Chris Carter of the University of Tasmania's School of Aquaculture says the discovery could save the aquaculture industry millions of dollars in fish food costs, ABC News reported. "I've always liked lupin as a replacement; it's got really good nutritional properties," he said. "We've tried it in salmon and trout...
