An added stipulation requires early notification of intention to fish. Open and closed seasons are imposed where necessary'. A whitefish quota management committee, comprising of members of the industry and national administration officials, meets monthly to undertake detailed analysis of key stocks including Cod, Haddock, Whiting, Hake, Monk, Megrim, Nephrops, Sole and Plaice, as well as deep sea species (see below). The majority of quota fisheries are controlled by means of separate Fishery Management Orders made by the Minister which restrict the fisheries as necessary, by setting catch limits per boat, according to the size of the vessel based on recommendations of the committee. The principal objective is to maintain access on an equitable basis throughout the year.
