Of all the fish caught worldwide nearly half are from scientifically monitored stocks and, on average, these stocks are increasing. An international project led by the University of Washington has compiled and analysed data from fisheries around the world and effective management seems to be the main reason why these stocks are at sustainable levels or successfully rebuilding. “There is a narrative that fish stocks are declining around the world, that fisheries management is failing and we need new solutions — and it’s totally wrong,” said Ray Hilborn, lead author and a professor in the University of Washington School of Aquatic and Fishery Sciences. “Fish stocks are not all declining around the world. They are increasing in many places, and we already know how to solve problems through effective fisheries management.”

Maine is undoubtedly the most productive lobster fishing state in the United States and catches has been high for the last few years.…

Falling fish population across the world are prompting innovators to look to the lab to find new ways at producing inexpensive fish products. Globally, demand for salmon has skyrocketed, along with demand for all fish, fueling overfishing and threatening the stocks of many fisheries. Fish and seafood now account for almost a fifth of the animal protein people consume making the need for a solution to a potential seafood shortage urgent. Maynard, United States based AquaBounty Technologies is hoping its genetically modified version of Atlantic salmon, which is says grows twice as fast as normal salmon, will soon become a top consumer choice. The company raises the salmon in land-based production systems that eliminate the various risks to wild fish, humans and the environment posed by farmed salmon.

The world’s oceans will likely lose one-sixth of their fish and other marine life by the end of the century if climate change continues its current trajectory, a new study finds. Every degree Celsius that the world’s oceans warm, the total mass of sea animals is projected to drop by 5% according to a comprehensive computer-based study by an international team of marine biologists at the American National Academy of Sciences. The Intergovernmental Panel on Climate Changes special report on global warming already estimates that as of 2017, human activities were responsible for global mean temperature rise of one degree Celsius above preindustrial levels. Unless reductions are made by the world’s leading carbon emitters the world will likely warm by two degrees Celsius above preindustrial levels by 2100.
