Greenback horse mackerel are an important commercial species with the main fishing grounds off the west coast of the North of New Zealand. Caught commercially with trawls, purse seines, traps and on line gear. The total catch reported for this species to FAO for 1999 was 15 529 t. The countries with the largest catches were Ukraine (15 306 t) and Russian Federation (223 t).

Commonly found near the bottom, in midwater and occasionally at the surface (Ref. 9258) in continental shelf waters (Ref. 27930). They form pelagic schools for most of the year but may move close to the sea bed during winter (Ref. 27931). Generally found at less than 300 m water depth with temperature less than 16° C (Ref. 9072). Juveniles inhabit coastal and estuarine waters although they may sometimes be found offshore (Ref. 27930). Feed mostly during the day mainly on krill and other planktonic crustaceans, light fish (Sternoptychidae) and lantern fish (Myctophidae) at the edge of the continental shelf (Ref. 27933).Seasonal patterns in the presence of surface schooling jack mackerel are thought to be a response to water temperature rather than evidence of migration, as surface schools are not generally found in water temperature above 17°C (Ref. 27933). Jack mackerel form schools of similar sized fish and there is evidence from demersal trawl surveys that the size of fish tends to increase with increasing depth of water (Ref. 5868).

Eggs and sperm are released amongst schooling fish, possibly deep in the water column near the edge of the continental shelf. Eggs are distributed between the surface and the thermocline and larvae are carried inshore by currents.

Greenback horse mackerel
(
İngilizce

wikipedia EN tarafından sağlandı
The greenback horse mackerel or greenback scad (Trachurus declivis) is a species of jack in the family Carangidae, found around western and southern Australia, and around New Zealand, from the surface to depths of 460 m. Its length is up to 64 cm.[2]
Its common name derives from the legend that other smaller species of fish could ride on its back over great distances. It is an important commercial fish and sports fishing quarry although it has strong tasting flesh.[3]
