Preliminary results from sea trials on an Orkney fishing vessel using a new net design developed by its skipper has shown a significant reduction in the amount of small cod caught, signalling its potential as an important tool for conserving stocks.
The trials highlight the pioneering role that Scottish fishermen are taking in developing new initiatives to aid in the conservation of fish stocks.
The results also come just ahead of crucial fish talks later this month in...

How marine animals find their way back to their birthplace to reproduce after migrating across thousands of miles of open ocean has mystified scientists for more than a century. But marine biologists at the University of North Carolina at Chapel Hill think they might finally have unraveled the secret.
At the beginning of their lives, salmon and sea turtles may read the magnetic field of their home area and "imprint" on it, according to a new theory in the latest issue of the journal...

To succeed on a long-term basis, companies must discover and utilise opportunities and handle threats. This is particularly critical in turbulent environments like the salmon industry.
But what actually are "opportunities" and "threats"? How do they arise? And how can they best be exploited or handled by the companies?
To shed light on these questions, scientists at Nofima Market have studied which opportunities and threats management in a selection of salmon companies...

NIFES has examined the levels of dioxins, dioxin-like PCBs and other PCBs in certain fish oils. In addition, a limited number of filet samples of mackerel, Greenland halibut and Atlantic halibut have been analyzed for dioxins and dioxin-like PCB, brominated flame-retardants and heavy metals. The analyses were done for the Norwegian Food Safety Authority.
The amount of data with respect to dioxins and dioxin-like PCBs in food is very limited in both Norway and the EU....

Since 1999 the National Institute of Nutrition and Seafood Research (NIFES) has annually (spring and autumn) analysed blue mussels from around 50 locations along the Norwegian coast in order to monitor the level of metals and other chemical components. The analysis are related to the Norwegian Food Safety Authorities surveillance programme.
The results show that blue mussels from some locations in the Sogne Fjord and the Hardanger Fjord have had a high level of total arsenic,...

To meet the growing demand for local food supply and emerging markets for marine products, the aquaculture sector is turning to biotechnology for ways to develop better fish spawns and even develop biofuel from marine algae. "Aquaculture production should increase to meet the demand for fisheries products," Evelyn Grace T. de Jesus-Ayson, scientist from the Aquaculture Department of the Southeast Asian Fisheries Development Center, said. In Southeast...

A trio of new Genome BC research projects is taking a genomics-based approach to tackle specific challenges within the Province's fisheries and aquaculture industry - and could mean significant environmental and economic benefits for fisheries management and the health of our oceans.
The research will provide scientific data to inform Fisheries and Oceans Canada's (DFO) fisheries management decisions and support the long-term sustainability of aquatic resources in BC...

Mercury levels in fish are prompting widespread consumption advisories and uncertainty among consumers over which species are safe to eat. Now researchers at North Carolina State University have developed a model that will help scientists and regulators around the country predict which areas are likely to have fish with high mercury levels - a breakthrough that should help officials address public uncertainty by developing health advisories for specific water bodies and fish...

Scientists at the University of Toronto analysed Canadian fisheries data to determine the effect of the "keep the large ones" policy that is typical of fisheries. What they found is that the effect of this policy is an unsustainable fishery.
In fact, the opposite policy (keep the small young ones and throw back the large old ones) would result in a more sustainable fishery. In short -- a big fish in the water is worth two in the net.
Put simply, a fish population will produce...

Imported land-based aquaculture products such as shrimp, prawns and crabs that were tested by the New Zealand Food Safety Authority (NZFSA) as part of a new survey contained no detectable levels of residues from antimicrobial drugs.
The survey was part of NZFSA's Food Residue Surveillance Programme (FRSP) to ensure New Zealand's food safety controls are working effectively and that those selling food meet their legal responsibilities to ensure it is safe, says Dr Paul Dansted, NZFSA...

Fishery experts have known for years that shrimp trawling operations in the Gulf of Mexico are contributing to sharp declines in the ranks of Red Snapper, one of the most delicious and popular marine fish on the seafood menu.
While it's clear that thousands of young snapper are killed and wasted after being inadvertently "by-caught" in shrimp nets, new research from Texas Christian and Louisiana State universities finds shrimp trawling also may be raising the level of toxic mercury...

The project to develop an instrument to measure the well-being of farmed fish has been awarded a NOK 25,000 prize from TTO Nord AS.
Nofima Marine in Tromsø, in collaboration with equipment manufacturer Thelma AS, developed technology to measure the well-being of farmed fish.
"We used to monitor the environment around farmed fish, but now we can ask the fish themselves how they are getting on. This is a pioneering innovation that we wish to honour," says...

Herring milt to fight malnutrition in Africa and better utilisation of Norwegian raw materials in omega-3 products are among the discussion topics.
This annual seminar has become an important meeting place for scientists and industries utilising marine raw materials in their products.
This year's seminar focuses on the topics process technology, feed ingredients and marine oils.
"How do we increase the value of the raw materials we harvest from...

VTT Technical Research Centre of Finland and its partners have launched ENERFISH, a three-year project concerned with producing biodiesel from the waste generated at a fish processing plant. To ensure the viability and rapid commercialisation of the technology, the partners are constructing a biodiesel production plant next to the Vietnamese fish processing plant Hiep Thanh Seafood JSC.
The project team is also developing a cooling system based on the use of carbon dioxide and a...

Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue. University of Utah bioengineers have made a synthetic version of this seaworthy superglue, and hope it will be used within several years to repair shattered bones in knees, other joints and the face.
"You would glue some of the small pieces together," says Russell Stewart, associate professor of bioengineering and senior author of the...

There are no large pelagic fish populations in the Southern Ocean. That is one of the conclusions after the Institute of Marine Research sent the research vessel “G.O. Sars” on a six-month mission to the southern hemisphere. Krill, on the other hand, is abundant in the Southern Ocean. We are busy analysing the findings of the mission in order to calculate the quantities more accurately.

Fluorogenic detector glows bright green when in contact with mercury and could be used onsite. Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. The technique involves a fluorescent substance that glows bright green when it comes into contact with oxidized mercury, the researchers report in the...

The first cardiovascular health study in China investigating the effect of seafood consumption on health parameters, shows a 20% decrease in disease markers in patients consuming salmon for lunch 5 times per week, for 8 weeks. The results were recently announced in a Chinese-Norwegian seafood seminar during a fisheries fair in Qingdao, China. Globally, many countries are battling lifestyle diseases and the trend is rising, also in China and Norway. Both countries sees an increase of...

Just after Americans have headed to the polls to elect their next president, a new report in the November 13th issue of Current Biology, a Cell Press publication, reveals how one species of fish picks its leaders: Most of the time they reach a consensus to go for the more attractive of two candidates. "It turned out that stickleback fish preferred to follow larger over smaller leaders," said Ashley Ward of Sydney University. "Not only that, but they also preferred fat...
