A catch limit of 620,000 tonnes covers the waters where krill fishing takes place, a figure set well below the level scientists believed would harm the overall stock. For 15 years, that total was divided between four active fishing zones, meaning the catch could not be concentrated entirely in one area. Then the zone-by-zone limits were allowed to lapse, and in the 2024/25 season more than 57 per cent of the entire annual catch came from a single zone – the waters around the Antarctic Peninsula – faster than it had ever been taken before.
