OUR MAIN SPECIES
Spawning time is similar as with golden redfish but the deepsea redfish has more larvae, or from 40,000 to 400,000. The main food is also zooplankton, mostly krill. It is benthopelagic as the golden redfish but differs as there seem to be two stock components; one is along the continental shelf break but the other below 500 m depth in the open ocean, living apparently a pure pelagic lifestyle.
The shrimp are hermaphroditic.
They start out male, but after a year or two, their testicles turn to ovaries and they complete their lives as females.
Unconfirmed sources indicate a maximum size of 180 cm. It can be found all around Iceland, but is much more common in the colder waters in the north and east. It chooses deeper waters than the Atlantic catfish, or a depth of between 100 and 700 m, mostly on mud or sand bottom. It is found in European waters from Spitsbergen in the north to the northern North Sea in the south. It is also around the Faroe Islands, in southern Greenlandic waters and from Labrador to Cape Cod in North America.
Dab probably spawns all around Iceland, earliest spawning starting from the middle of April off the southeast coast then spreading clockwise around the country. The last spawners are along the east coast where spawning probably starts around the middle of June. The diet of the dab is variable, it is an opportunistic feeder and can handle large food items. Various benthic invertebrates are common in the diet, as are sandeels and capelin. Discarded intestines from fishing boats are commonly found in dab stomachs.
It is found in European waters from Murmansk in the north to Ireland in the south. It also occurs around the Faroe Islands, in southern Greenlandic waters and from Newfoundland to Cape Cod in North America.
It has a streamlined shape and is consequently a very good swimmer. It can swim rapidly all over the Icelandic continental shelf and individuals tagged in Icelandic waters have several times been fished along mainland Europe. Fishes tagged in Europe have also been fished in Icelandic waters. The saithe is native to European waters from Murmansk in the north to the English Channel in the south. It is also found around the Faroe Islands, in Greenlandic waters and from Labrador to Cape Cod in North America.
Mostly it occurs over soft bottoms at depths between 10 and 200 m. It is found in European waters from Spitsbergen and the White Sea in the north to the Bay of Biscay in the south. It also occurs around the Faroe Islands, in southern Greenlandic waters and from Labrador to Cape Cod in North America.
It is found over a wide depth range, spanning from 15 to 1000 m depth. Usually the younger fish are in shallower waters. It is found in European waters from northern Norway to the Mediterranean Sea. It also occurs around the Faroe Islands, and has been reported off southern Greenlandic waters and on the Grand Banks off Canada.
It is primarily a deep water fish, found in the depth range of 130 to 1500 m but mostly at a depth of between 300 and 800 m. It is found in European waters from Murmansk and into the Mediterranean Sea. It also occurs around the Faroe Islands, and has been reported in waters off southern Greenland and on the Grand Banks, off Canada.
Plaice is common all around Iceland from the seashore to 200 m depth, on sandy or muddy bottoms. It can also tolerate fresh waters for some time. In European waters it is found from the White Sea and the Barents Sea in the north down to the western part of the Mediterranean Sea in the south. It is not found in North American waters. Previously, flatfishes were considered rather sedentary. Tagging studies on the plaice have, however, shown that this does not hold entirely true. The plaice undertakes large scale feeding and spawning migrations in the waters around Iceland, fishes tagged on one side of the country have even found at the other side.
It mostly occurs on mud or sand bottoms at depths between 40 to 200 m. It is found in European waters from Murmansk in the north to the English Channel in the south. It is also around the Faroe Islands, in southern Greenlandic waters and from Labrador to Cape Cod in North America.
Cod is “the fish” in Iceland. It is by far the most important marine resource in Icelandic waters. Its economic importance has only briefly been surpassed by herring in the 20th century and possibly Greenland shark in the 19th. The cod is also a large, fecund, greedy and rather fast growing fish and therefore has great impact on other marine species in Icelandic waters.
The history of fisheries around Iceland has more or less rotated around the cod. Measures to manage the fisheries by extending the EEZ, closing areas to fishing and controlling the fleet size and the amount fished, have all been primarily aimed at the cod but only later also been applied to other species. The evolution of the fish processing industry has also primarily been because of the cod. The cod fisheries have, therefore, shaped Icelandic society for centuries. The only species that approaches the cod in historical importance has been the herring, but then only during the late 19th and early to mid 20th century.
It occurs in European waters from Murmansk in the north to the Mediterranean Sea in the south but also around the Faroe Islands, in Greenlandic waters and, in small amounts, off North America. A related species, Micromesistius australis, lives in the Southern hemisphere.
The eggs and larvae drift north to the continental shelf of North Iceland or Greenland. It gradually migrates further north as it grows and spends the time before maturity feeding in the Iceland Sea on zooplankton, mainly copepods. Maturity is usually reached at the age of 3, but some become mature one year earlier or later.
At this time they condense into large schools and migrate around Iceland, usually clockwise to the spawning grounds in the south. During these migrations the capelin becomes the main food of many species in Icelandic waters, most importantly the cod. Spawning takes place in very shallow waters and is a very intense behavior. After spawning all the males and most of the females die.
Mostly it occurs on rocky or sandy bottoms at depths between 50 to 350 m. It is found in European waters from Murmansk in the north to the Bay of Biscay in the south. Also around the Faroe Islands, in Greenlandic waters and from Labrador to Cape cod in North America.
