Catch-and-Release Strategy Could Change Fish Evolution
The practice of catch-and-release in recreational fishing may be permanently changing fish populations, a study from the University of Connecticut shows....
Zebrafish Help with Larger Scale Gene Function Studies
A relatively new method of targeting specific DNA sequences in zebrafish could dramatically accelerate the discovery of gene function and the identification of disease genes in humans, according to scientists at the National Human Genome Research Institute...
How a Box Jellyfish Catches Fish
The first feeding study of tropical Australia's Irukandji box jellyfish has found that they actively fish. They attract larval fish by twitching their extended tentacles, highlighting their nematocyst clusters (stinging structures) and using them as lures....
Environmental, Economic and Social Evaluation of Africa's Small Scale Fisheries
Small-scale fisheries (SSFs) in developing countries are extremely important for local communities, as they are a major source of food, livelihood, and income. This report from the World Bank looks at several case studies of fisheries in Africa and how...
Differences in Metabolic Rates of Exploited and Unexploited Fish Populations
In a paper published June 3, 2015 in the online journal PLOS ONE, University of Connecticut researchers Jan-Michael Hessenauer and Jason C. Vokoun, both in the Department of Natural Resources and the Environment, report on fisheries induced evolution...
GM in Aquaculture
The use of genetically modified organisms in the food industry is a highly controversial topic. In this article, for TheFishSite, Sam Andrews discusses the sustainability aspects of GM in aquaculture but also the questions around what negative effects...
The Role of Women in the Seafood Industry
One in two seafood workers is a woman. This worldwide desktop study by the FAO, the first of its kind, presents what is known, and what remains to be investigated in this crucial component of the seafood industry....
Fish Born in Larger Groups More Sociable
A new study from The University of Cambridge shows that cichlid fish reared in larger social groups from birth display a greater and more extensive range of social interactions....
Mate Competition Weeds out GM Fish from Population
Purdue University research has discovered that wild-type zebrafish consistently beat out genetically modified Glofish in competition for female mates, an advantage that led to the disappearance of the transgene from the fish population over time....
Polystyrene Nanoparticles Affect Fish Behaviour and Metabolism
Fish fed polystyrene nanoparticles are less active and show changes to their brains and metabolism, according to a study by Swedish and Danish researchers. The findings suggest that nanoparticles in the environment could have a major impact on fish...
Warm-Blooded Fish Swim Further and Faster
Fish species capable of warming their body core are able to swim two and a half times faster than those whose body temperature does not change, according to a study from the University of California, Santa Barbara and other institutions....
Coastal, Fishing Lights Found to Alter Marine Ecosystems
Marine ecosystem composition can be changed by night-time artificial lighting from coastal communities, shipping and offshore infrastructure, according to new research....
World Governments Must Take Action to Protect Ocean Economy
Governments around the world must take action to safeguard the contributions of the oceans to the global economy, which are valued at $24 trillion, according to this report from the WWF: 'Reviving the Ocean Economy - The Case for Action - 2015'....
Best Practices in Tuna Longline Fisheries
Bycatch from longline tuna fisheries is a global environmental problem. This report from the Sustainable Fisheries Partnership shares some examples of best practice to avoid harming non-target organisms....
Factors Influencing Ostreid Herpesvirus Mortality of Pacific Oysters
Mortalities of oyster Crassostrea gigas seed associated with ostreid herpesvirus have been observed in many oyster-producing countries since 2008. This report, by Bruno Petton and colleagues from the French Research Institute for Exploitation of the Sea,...
