Some of the world’s poorest countries will be hit hardest as climate change affects marine fisheries all over the world, according to a new study.

The global fishing industry produces a total catch worth of about $90bn (£71bn) but the warming ocean temperatures are causing many valuable species to shift their usual ranges.

The potential for water to hit temperatures lethal to corals such as Australia’s Great Barrier Reef, which support vast amounts of other marine life, is a particular problem.

The researchers assessed 147 countries based on their vulnerability to the effect of future warming on fishing in their waters and their ability to cope with the changes.
