Technological advances are allowing commercial fishing fleets to double their fishing power every 35 years and put even more pressure on dwindling fish stocks, new research has found.

Researchers from the Sea Around Us initiative at the University of British Columbia analyzed more than 50 studies related to the increase in vessels’ catching power and found that the introduction of mechanisms such as GPS, fishfinders, echo-sounders or acoustic cameras, has led to an average two per cent yearly increase in boats’ capacity to capture fish.

Fish that follow ‘gourmet diet’ more threatened by climate change

Fish that follow a ‘gourmet diet’ may be more threatened by climate change and other environmental variations than those that are not picky eaters, new research from the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries, the University of New Brunswick, and the Fisheries Department at the U.S. National Oceanic and Atmospheric Administration has found.

In a study published in Scientific Reports, researchers found that in the more biodiverse areas of the world’s oceans like the tropics, where there are also a diverse number of habitats and environments, fishes tend to be selective about what and where they eat, choosing areas and foods that match their feeding skills and the place they occupy in the food chain.

Shark and ray species commonly caught in the Mediterranean and Black seas are not being reported in official statistics, new research from the Sea Around Us initiative at the University of British Columbia shows.

A new study published in Marine Policy reveals that 97 per cent of the sharks and rays caught and brought to market domestically by fleets from the European, North African and Middle Eastern countries that surround these seas are not reported by species.
