Fishing industry in Denmark for mackerel fish is also the same on one vessel. Additional sprat quota/sandeel quota may be purchased for Baltic Sea sprat and Norway pout fishing. The type of vessels forming the fishing fleets are; trawlers, gill netters and poundnets (50% in this category but with capacity of less than 5GT mostly gill netter); trawlers and purse seiners of 150 GT. A substantial part of the fleet operate under depths of 24 m. After a few prosperous years for Denmark's fishing industry, figures for 2012 were not so good with profits falling to some DKK 600 million from DKK 900 million
Individual fishing quota outside speculation in IFQs by non-fishermen. A lack of regulatory policy or enforcement still results in the prevalence of "armchair fishermen" (those who own quota but do not materially participate in the fishery). Since IFQs began in 1995, the commercial longline fleet has never exceeded these fisheries' TACs. ITQs may have the effect of changing the criteria that fishermen apply to their catch. Highgrading involves catching more fish than the quota allows and dumping specimens that are less valuable because of size, age or other criteria. Many of the discarded fish are already dead or quickly die, increasing fishing's reduction
