Atlantic Cod Actively Avoid CO2 and Predator Odour, Even After Long-term CO2 Exposure
The rising atmospheric CO2 level is continuously driving the dissolution of more CO2 into the oceans, and some emission scenarios project that the surface waters may reach 1000 ?atm by the end of the century, write Fredrik Jutfelt and Maria Hedgärde,...
Salt Stratification Determines the Fate of Fish Stocks in the Baltic Sea
In the Baltic Sea, two cod stocks evolve independently. Also the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possibly due to the irregular distribution of water masses of different...
Catching, Handling and Transport: The Implications for Fish Welfare
For many farming practices, the capture, handling and transport of fish is an essential requirement; however with each of these activities found to be a stressful process, what are the implications for fish welfare? Hannah Chilvers, writing for TheFishSite.com,...
Breeding Cod More Adapted to Aquaculture
Terrestrial livestock are so different that they often have nicknames, but thousands of farmed fish look so similar that many are surprised to learn that biologists claim that fish may have different “personalities” too. Scientists at Nofima have...
Lobster, Cod Benefit from Small-scale Northern Marine Protected Areas
Marine protected areas (MPAs) are increasingly implemented as tools to conserve and manage fisheries and target species. Because there are opportunity costs to conservation, there is a need for science-based assessment of MPAs. Here, Even Moland, Flødevigen...
The Regulation of Puberty and Maturation in Cod
FSH and LH are two important hormones which regulate the processes of puberty and maturation. These hormones are secreted by the pituitary gland and are transported in the blood to the genitalia, where they regulate maturation....
Wild-Caught Cod – the Juveniles of the Future in Cod Farming
During earlier trials involving wild cod in captivity, scientists at Nofima have experienced problems getting the cod to eat pellet feed. Nofima, in collaboration with the Institute of Marine Research and SINTEF Fisheries and Aquaculture, has now demonstrated...
Temperature Effect on Spleen Transcriptome Response to Intraperitoneal Viral Mimic Injection in Cod
This report by Tiago S Hor et al, Memorial University of Newfoundland, looks at how a moderate increase in ambient temperature modulates the Atlantic cod (Gadus morhua) spleen transcriptome response to intraperitoneal viral mimic injection....
Link Between Carbon Dioxide and Blindness in Cod Explored
Based on extensive studies carried out in the last five years, University of Maine Ph.D. student Kevin Neves and the University of Maine’s Center for Cooperative Aquaculture Research (CCAR) Director Nick Brown have determined that cod living at high...
How Fresh is Fresh? Perceptions, Experience When Buying, Consuming Fresh Cod
Most of us do not buy fresh fish that was caught more than three days ago. But if we do not know the date of capture, we are devouring fish that is often far older, says Nofima Scientist Jens Østli, and colleagues, who invited over 400 fishing customers...
Cultured Aquatic Species - Atlantic Cod
Information on the culture of the Atlantic Cod from the FAO Cultured Aquatic Species Information Programme....
Polar and Atlantic Cod Share Habitat, not Diet
Despite Atlantic cod and haddock extending further into Arctic waters, a new study reveals there is little competition for food between the invaders and native polar cod. However, it is uncertain whether climate change will increase competition between...
Climate Warming May Enhance Polar Cod Survival
Researchers have demonstrated that hatching in polar cod can begin as early as January in Arctic seas that receive large freshwater input, compared to April-July in seas with little freshwater input. Since early hatching leads to higher survival rates,...
“Healthy” Farmed Cod Undergo Extensive Pathological Changes
Doctoral research carried out by Mona Gjessing from the Norwegian School of Veterinary Science shows that pathological changes in cod differ from those found in diseased salmon, and cod that appear clinically healthy can nevertheless be affected by extensive...
Reducing Salt In Already Desalted Cod
A team of researchers from the Universitat Politècnica de València’s CUINA group has achieved a 50 per cent reduction in the amount of salt in already desalted cod, thus obtaining a final product that preserves all its sensory properties and is particularly...
