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...

"Aquamanna" cleared customs yesterday, and will soon be anchored at the Atlantic Marine Aquaculture Center's offshore demonstration site. Constructed according to UNH specifications in Canada, the remotely operable, 80-ton automated fish feeding buoy holds 20 tons of food, and can feed four different crops of fish at a time. Its development has been a priority for the Center's offshore aquaculture research, and it will be used to feed the Center's current crop of cod, and 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....

MALAYSIA - According to the operations manager of the fisheries graduates group, Nik Mohd Firdaus Nik Daud, the Omega 3 content of Omega 3 catfish is about 2.3-2.5 percent as compared to only 0.02 percent in the other catfish breeds. "The Omega 3 catfish is different as we formulated its feed by using a special mix of fish feed, starch pellets, soya bean, fish oil and a mix of minerals, vitamins and palm oil." Nik Mohd Firdaus said the group collaborates with...

Farmed fish from Asia can provide Norwegian fish with tough competition in the European market place, according to a report prepared by Fiskeriforskning. Sales of skinless and boneless pangasius fillets are rising rapidly in Europe. It is in particular the farmed fish species pangasius - also known as Vietnamese pangasius catfish - that is showing strong growth in Europe. Vietnam is the largest producer of this white fish species. The white flesh and low price results in...

Thermo Fisher Scientific Inc., the world leader in serving science, today announced that the company has developed three food testing methods in response to recent concerns over contamination of imported seafood. On June 28, the U.S. Food and Drug Administration (FDA) banned the import of certain fish species from China because of possible contamination with drugs and unsafe food additives — including nitrofuran, malachite green and chloramphenicol — which are prohibited in food...

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...

A new Glitnir Seafood Industry Report shows that the global catch of tuna has stagnated and the stocks of the most popular subspecies are currently either fully exploited or even in a stage of depletion. The future of the tuna industry depends largely on the development of successful aquaculture. Glitnir, the globally leading supplier of financial services to the seafood industry, releases its new report on the tuna industry today. The report provides an analytical overview of the...

Bluefin tuna use three times as much oxygen as other fish their size, making them more difficult to culture, according to new research at the University of Adelaide. The findings have been made by Earth & Environmental Sciences PhD student Quinn Fitzgibbon and colleagues, in a study where they monitored live tuna swimming inside a 350-tonne "waterbed". The research team also found that tuna use twice as much energy processing their food as any other fish, and so need to eat...

Aqua Gen AS was Tuesday night awarded the Nor-Fishing Foundation Innovation Prize 2007 of NOK 100,000. The company won the Prize for its salmon and trout egg grading machine. This is how the Jury describes this year’s winner: It has taken one year, in co-operation with research communities, to develop a completely new machine in a field where similar equipment does not exist. This is a very bold initiative involving top expertise. The product has a global market. Grading eggs is...

The implications of breeding between farmed and wild salmon will be investigated in a new project led by scientists at the University of East Anglia. For the first time researchers will measure the fertilisation compatibility between farmed and wild salmon, and therefore the risk of farmed genes entering wild populations, which are in severe decline. Wild Atlantic salmon stocks have fallen by more than 50pc, mainly through poorly-managed fisheries and deterioration of feeding and...

The Marine Products Export Development Authority (MPEDA) is developing pathogen-free shrimp at Port Blair in the Andamans. Its is the first such project in the country.
According to Seafood Exporters Association of India (SEAI) sources, the MPEDA aims at matching the growing demand for shrimp broodstock (adult shrimp for breeding) for aquaculture farms across the country.
With Indian shrimp exports accounting for over half of its export earnings of $1.8 billion, the MPEDA is...

So what does an underwater cage full of white sea bass miles out in the ocean have to do with a sugar beet farm in northern Utah? Everything, as far as Donald Kent is concerned. It was a sugar beet farm that sustained Kent's father, Sidney Kent, and his family during the Great Depression. And though the elder Kent eventually left the farm and moved to San Diego to become a physical therapist, the farm never really left him. “He loved working the land and taught us about food...
