There are 150 tonnes of fish in this one haul. It used to take a fishing vessel 1 one whole year to catch this many fish. These are mostly yellow fin 2 tuna, plus some skip jack 3. As they're slower breeders than skip jack, many yellow fin are caught before they're old enough to breed. This makes them more vulnerable to over-fishing. Tuna fishing has grown into an 8-billion-dollar industry. And over 4 million tonnes of tuna are caught worldwide each year, a four-fold increase in as many decades. Almost 2/3 of the catch now comes from the Pacific. In the Atlantic, yellow fin catches have been shrinking since 1990. Now a similar decline has begun in the Pacific. Tuna need to swim constantly to keep water flowing over their gills, otherwise they can't breathe. The fishermen want to get them out of the water as quickly as possible. When starved of oxygen, a build-up of lactic 4 acid in their muscles causes the quality of their meat to deteriorate 5.
