Taxonomically, Argentine mackerels were first considered as Scomber japonicus marplatensis and later as Scomber japonicus Houttuyn 1782, although, in the last years, different studies have suggested that South Atlantic mackerel species belongs to Scomber colias Gmelin 1789. These latter results, incorporated in the main fish databases (FishBase and Catalog of Fishes), promoted a phylogenetic st...

Population genetic structures of the mackerel (Scomber scombrus) and chub mackerel (Scomber japonicus) were studied in the Mediterranean Sea. Fragments of 272 bp (S. scomber) and 387 bp (S. japonicus) of the 5'-end of the mitochondrial control region were sequenced from spawning individuals collected off the coasts of Greece, Italy, Spain, and Portugal. High levels of mitochondrial control regi...

Chub mackerel (Scomber japonicus Houttuyn, 1782) were obtained from the commercial fishermen in Çanakkale, Turkey, July, 2017. We examined a total of 40 fish (20 non-infested and 20 infested) assessed biometric indices, haematological parameters serum biochemical variables. The hepatosomatic index gonadosomatic infested chub lower than those fish. Blood haematocrit ratio haemoglobin concentrati...

Chub mackerel (Scomber japonicus Houttuyn, 1782), is a coastal pelagic fish species that usually lives between the surface and depths of 250 or 300 m (BAuCHOt, 1987). It is a geographically widespread species that inhabits the moderate and warm waters of the Atlantic, Pacific and Indian Oceans (COllEtE & NAuEN, 1983). It is also rather frequent in the Mediterranean and its adjacent seas (Black ...

The systematic status and the evolutionary biology of chub mackerel (Scomber japonicus) in the South West Atlantic Ocean is confusing with an unknown degree of genetic differentiation and reproductive isolation between units. Simultaneous genetic and morphologic analyses were made on 227 fish collected from two areas of the South West Atlantic Ocean and one from the Mediterranean Sea. The genet...

Abstract This study was carried out in April - June 2014 to determine absolute fecundity (F) of the chub mackerel (Scomber japonicus Houttuyn, 1782) Saros Bay (Aegean Sea, Turkey). The relations between and total length, weight age females were estimated as F=0.0318TL4.81, F=1573.9TW- 42858 F=109607A-136129, respectively. aims contribute reproductive biology S. by reporting first findings about...
