The commission consists of representatives from the fishing, scientific, business, and environmental communities as well as a commissioner's designee from the Department of Marine Resources.

It does not consider any multiplier effects that would come from an iMaine State LibraryMaine State DocumentsMarine Resources DocumentsMarine Resources34335A Report to the Joint Standing Committee on Marine Resources Re A Report to the Joint Standing Committee on Marine Resources Regal of Maine's fishing industry, by Briggs, Townsend and Wilson (see Marine Fisheries Review, January 1982) additional fish landings result in an added benefit to both the harvesting sector and processing sector. The multipliers for incomes generated from additional landings are 1.32 for harvesters an A Report to the Joint Standing Committee on Marine Resources Regad 1.33 for processors.
