Capture-based aquaculture will give Norwegian seafood a competitive advantage. However, uncertainty about profitability means that few fishermen go in for live fish, a Fiskeriforskning study shows. The Norwegian fishing industry can gain a competitive advantage by landing more live fish. There is an increasing demand for fresh fish. However, large seasonal fluctuations in the fisheries mean there are long periods with insufficient supply of fresh fish products....

Scientists have managed to breed trout from salmon using a new technique they hope will allow them to create tuna fish from mackerel. The Japanese researchers hope to produce stocks of valuable, endangered species by injecting their germ cells into sterilised embryos from other species. Goro Yoshizaki, a marine biologist, from the Tokyo University of Marine Science and Technology, Japan, used the method to successfully breed trout from salmon. The embryos they produced...

To protect fish farms and hatcheries from outbreaks of water-borne diseases, water treatment specialist Hanovia Limited has developed a high intensity UV disinfection system. Capable of treating up to 700m3/hr of both fresh or sea water with at least a 99.99% kill rate, the UV system can be used to treat both incoming and recirculation water, allowing flexibility in the choice of site and a rapid payback for farmers. Increased water extraction and lowered water quality can result...

A farmer whose sole product is fish can harvest bigger profits if a vegetable or herb crop is added to the system, said presenters at a conference on aquaculture. This form of agriculture, called aquaponics, is still rare in Alberta, said Nick Savidov, a research scientist with Alberta Agriculture's crop diversification centre in Brooks. Bacteria convert the fish waste to nutrients, which are taken up by plants growing in hydroponic troughs. The plants clean the water, which is...

Recent trials have shown that the salmon harvesting plants can commence using a machine that slaughters salmon quickly and humanely. The current method in use, CO2, will be banned from 1 July next year. Industry-scale trials have been carried out at one of Marine Harvest's salmon farming plants in Rogaland. The salmon are pumped up directly from the pens to a vessel that had been especially outfitted for the trials. Trials were also carried out using a system...

Prawns turn a deeper shade of red if you dunk them in a black bucket of water for a few hours, say Australian scientists. They say the prawns are trying to blend into the dark background, so change their pigmentation to match. As the public tends to favour darker coloured prawns, this simple step will increase the market value of farmed prawns, says CSIRO's Dr Bruce Lee, who was speaking at a recent conference in Sydney. It may also make the prawns more nutritious as the...

Royal DSM N.V. announced last week its newest innovation in carotenoids: CAROPHYLL® Stay-Pink. This concept, adapted from nature, makes a generational step in existing carotenoid technologies. The DSM technology makes use of an improved structure to protect the astaxanthin molecule. Astaxanthin is the carotenoid that provides the typical rich color associated with salmon flesh. Based on the need of today’s customer, the major concern for astaxanthin is its stability during the...

Cow manure and fish guts and maggots. It could all soon be dinner -- if you're an Idaho rainbow trout. University of Idaho and Idaho State University scientists are working on a new maggot-based feed capable of fattening rainbows for the dinner table, while simultaneously helping slash growing mounds of manure and fish entrails. Idaho is America's largest commercial producer of trout, with the industry bringing in more than $35 million annually. And with 500,000 cows, it's...

A new environmental study proves atmospheric mercury emissions end up in fish in as little as three years, and concludes that if mercury emissions from coal-fired power plants and other industrial activities were cut immediately, the amount of mercury in fish would begin to go down within a decade. "Before this study, no one had directly linked atmospheric deposition (mercury emissions) and mercury in fish," said University of Alberta biological sciences professor Vincent St....

JAPAN - Transplanting reproductive cells between fish may help preserve endangered species or resurrect extinct ones, scientists in Japan say. Researchers at Tokyo University of Marine Science and Technology injected immature sperm-creating cells from rainbow trout into salmon embryos with abnormal chromosomes to produce normal trout with healthy offspring. They also froze and thawed reproductive cells, known as spermatogonia, as a way to store genetic material of endangered fish....

Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes’ hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found. Incidents of seasonal low levels of oxygen, known as hypoxia, have increased dramatically in coastal waters throughout the world over the past few decades, largely as a result of increased run-off from human agricultural and industrial activities. Hypoxia’s long-term impact on marine...

You can see and smell if a fish is good, but determining its keeping quality requires more precise methods. At Aqua Nor, Fiskeriforskning demonstrates a freshness gauge that gives the answer at once. To determine how fresh the fish is - and provided it has been properly stored - fish fillet producers work out the time since the fish was caught. Different species of fish have different keeping qualities. For example, fresh salmon can be stored several days longer than fresh cod...

Fish and marine mammals are becoming deaf, failing to reproduce and even dying because of underwater man-made noise pollution, an Italian expert warned on Friday. Fabrizio Borsani, an acoustic resarcher with the Rome-based marine research institute ICRAM, said his fears were shared by many colleagues who gathered in Denmark earlier this month to discuss how the problem is affecting sea life. "Research and studies presented in Nyborg, at the first international conference held...
