Seriola quiqueradiata is a species from the family of jacks (Carangidae), which is distributed in the northwestern Pacific from Japan to Hawaii . It is a species that is coveted as a food fish in Japan and there in the fish trade u. a. occurs under the name Japanese 鰤 buri .
description
Seriola quiqueradiata has an elongated, laterally flattened body with a yellow longitudinal line. The sideline is free of flakes. The pectoral and pelvic fins are about the same length. Two spines stand in front of the anal fin, which is shorter than the rear dorsal fin with soft rays. The spines of the anterior dorsal fin are connected to one another by a skin.
The largest individual was caught with a length of 150 centimeters, the heaviest with a weight of 40 kilograms.
Way of life
The mackerel is a fast swimmer in the pelagic and during the day chases other, smaller fish such as mackerel , horse mackerel and sardines , while squids are also part of the prey spectrum.
The published maximum age of the species is 6 years, the animals reach sexual maturity from 3 years. Young animals migrate northwards in early summer using the Tsushima and Kuroshio currents to reach their feeding grounds. In late autumn the animals move south again to the wintering areas. Occasional cannibalism has been observed among young animals.
Economical meaning
It is practiced in the Far East aquaculture with this species. The first facilities were established in Kagawa Prefecture in 1927 . Young animals caught in the wild were raised in enclosures near the beach. This method was abandoned because the maintenance of the required water quality and the removal of waste from the system could not be guaranteed. Commercial rearing began in the 1940s. From the 1960s onwards, production increased rapidly, exceeding 43,000 tons in 1970. An all-time high of almost 170,000 tons was in 1995, and between 1996 and 2003 the amount farmed fluctuated between 139,000 and 162,000 tons. No further growth can be observed, but the results of the fish farms are stable despite a decrease in the number of young animals caught in the wild. Most aquaculture takes place in Japan, the only other country where the species is cultivated is South Korea . Adult animals caught in the wild come from the western central Pacific ( FAO area 71). The species makes up 57 percent of the total amount of aquaculture marine finfish produced in Japan.
