Kosterhavet National Park is home to Sweden's largest seal colony.[5]


The environment in the park is unique to Swedish waters. Over 6,000 marine species have been identified, about 200 of them can not to be found elsewhere in Sweden. The Kosterfjord (English: Koster Fjord)[6][7] is 200 m (660 ft) deep with relatively low temperature – 5 to 7 °C (41 to 45 °F) – and high salinity (about 35%). Brachiopod, sponge and coral larvae are brought in by currents from the Atlantic. Rare seabirds, such as Arctic terns and skuas, along with a large population of harbor seals have their habitat here. Plaice, cod and sea trout breed in the more shallow waters closer to the shore.[8][9]

Professional fishing is allowed although special regulations apply. The waters of the park is significant for the fishing of northern prawn and Norwegian lobster. Fishing is not subject to environmental protection, and are instead regulated by fishery laws and an agreement from 2000.[10]
