WHAT ARE THE THREATS FACING COD AND HADDOCK?

Overfishing has decimated cod and haddock stocks a number of times. Most recently, haddock from three North Sea and west of Scotland fisheries were removed from sustainable seafood lists because stocks had fallen below acceptable levels in 2017. During the 1990s, Newfoundland in Canada was forced to ban cod fishing because stocks were nearly wiped out.

While rising sea temperatures reduces the size of cod and haddock, it also forces the fish further north in search of cooler waters. Other fish not traditionally found in UK waters will appear more frequently too - with mixed consequences. For example, cuttlefish and sardines are being caught in increasing numbers, but researchers have warned slipper limpets could ruin oyster and mussel beds.
