Haddock and cod are staple wholesale groundfish products, and although remarkably similar, contain several distinguishing features. Among these differences, throughout the history of fishing the two species, has been the availability.
Haddock is often more expensive than cod, and one of the main reasons for this is because of its relative scarcity compared to the availability of cod. In fact, worldwide cod catches peaked in 1970 at three-million tons, though the cod stocks since then have suffered significantly. Therefore, in 1992, Canada initiated a moratorium to in hopes to sustainably rebuild depleted cod stocks.
Haddock stocks, on the other hand, appear to be steady and in good shape. The United States and Norway, two name two, have conducted experiments to farm haddock, and the results have concluded this as a possibility.
Seafood in this category is abundant, well-managed and caught or farmed in environmentally friendly ways.
These items are an option, but there are concerns with how they're caught or farmed-or with the health of their habitat due to other human impacts.
Take a pass on these items for now. They are caught or farmed in ways that harm other marine life or the environment.
