Haddock
Most haddock that are caught off the coasts of New England, Canada, Iceland, and Norway are caught using habitat-damaging, high-bycatch bottom trawls. Bycatch is a serious problem in some fisheries because many bottom dwellers are caught along with the Haddock, including overfished cod.
Haddock are under heavy regulatory controls and, as a result, some populations are now at healthy levels of abundance. However, the way that Haddock has been fished seems to have created a situation in which the fish are maturing earlier in their life cycles than in the past. Younger, smaller fish are producing fewer eggs, and this may impact population growth in the future.
