seine nets, trawlers, long lines and gill nets and is often caught in mixed species fishery with other groundfish species such as cod and whiting. The main fishing grounds in the eastern Atlantic are in the Barents Sea, around Iceland, around the Faeroe Islands, in the North Sea, Celtic Sea, and in the English Channel. Landings in the eastern Atlantic have fluctuated around 200–350 thousand tonnes in the period 1980–2017. During the 1980s, the largest portion of the catch was taken at Rockall but from about 2000, the majority of the catch is caught in the Barents Sea. All the stocks in eastern Atlantic are assessed by ICES which publish a recommendations on an annual basis for Total Allowable Catch. In the western Atlantic the eastern Georges Bank haddock stock is jointly assessed on an annual basis by Canada and the United States and the stock is collaboratively managed through the Canada-United States Transboundary Management Guidance Committee, which was established in 2000. The commercial catch of haddock in North America was approximately 40–60 thousand tonnes per year between 1920 and 1960. This declined sharply in the late 1960s to between 5 and 30 thousand tonnes per year. Despite a few good years post-1970, landings have not returned to historical levels. Haddock currently resides on the Greenpeace seafood red list due to concerns regarding the impact of bottom trawls on the marine environment. In contrast, Monterey Bay Aquarium considers haddock a "good alternative". Many haddock fisheries have been certified as sustainable by the Marine Stewardship Council. All seven stocks assessed in the eastern Atlantic are currently considered by ICES to be harvested sustainably. The haddock populations in the western Atlantic (offshore grounds of Georges Bank off New England and Nova Scotia) are also considered to be harvested sustainably. As food Haddock is very popular as a food fish. It is sold fresh or preserved by smoking, freezing, drying, or to a small extent canning. Haddock, along with Atlantic cod and plaice, is one of the most popular fish used in British fish and chips. When fresh, the flesh of haddock is clean and white and its cooking is often similar to that of cod. A fresh haddock fillet will be firm and translucent and hold together well but less fresh fillets will become nearly opaque. Young, fresh haddock and cod fillets are often sold as scrod in Boston, Massachusetts; this refers
