Steroidogenesis in Ovarian Follicles of Chub Mackerel, Scomber japonicus
Zoological Science, 2005We incubated different radiolabeled steroid precursors with intact chub mackerel ovarian follicles to clarify the synthetic pathways of steroid hormones during vitellogenesis and following final oocyte maturation (FOM). During vitellogenesis, estradiol-17beta (E2) was synthesized from pregnenolone via 17-hydroxypregnenolone, 17-hydroxyprogesterone ...

Fecundity of the Argentinean mackerel Scomber japonicus marplatensis
Marine Biology, 1969Research on the spawning and fecundity of the Argentinean mackerel Scomber japonicus marplatensis was carried out during the spawning season 1966/67. The purpose of the present study was to obtain data for the estimation of the number of eggs which can be produced and spawned by one female of a known size, during one season of reproduction: 152 females

Diet of the chub mackerel Scomber japonicus in the eastern Adriatic Sea
Cahiers de biologie marine, 2012Scomber japonicus is a pelagic fish species that is widely distributed around the world. The sample of chub mackerel (N = 400) in this study was collected during 2007 and 2008, from the commercial purse seine catches in the eastern part of the Adriatic Sea. Nine taxonomic groups of prey were found in the stomachs of chub mackerel.

Marine Pollution Bulletin
Scomber australasicus and Scomber japonicus are species of considerable economic importance in the Northwest Pacific Ocean, playing crucial roles in local food webs and energy flow. We combined stable isotope analysis of muscle tissue with fatty acid profiling to investigate their feeding ecology and interspecific relationship.

Food Science and Biotechnology, 2011
The heavy metal contents and chemical compositions among mackerel species were investigated. Atlantic and chub mackerel had higher mercury, but lower lead than blue mackerel. Chub mackerel had the highest crude fat (18.62%) and the lowest moisture (58.29%), whereas blue mackerel had the highest moisture (70.10%) and the lowest crude fat (2.89 ...

Mitochondrial DNA Part A, 2015
Mackerel is marketed at prices according to the species type, Scomber japonicus and Scomber scombrus. Distinguishing these two species with the naked eye is difficult, and their differentiation becomes more difficult after they are processed by cooking, thereby leading to counterfeiting issues.

Maturation and growth of Pacific Mackerel, Scomber japonicus Houttuyn
2021The maturation of Pacific mackerel has never been documentedclearly. Analysis of data reveals spawning can occur fromMarch through October, but the majority takes place from Aprilthrough August. During this April through August period,22.5%, 65.7%, 75.1%, 84.7%, 84.2%, and 87.5% of the femalefish were mature or maturing for Age Groups I, II, III, IV, V,

Spectral sensitivity of juvenile chub mackerel (Scomber japonicus) in visible and ultraviolet light
Fish Physiology and Biochemistry, 2008Although chub mackerel (Scomber japonicus) is widely distributed all over the world, the relevance of its visual sensitivity to its ecology is not yet fully understood. We investigated spectral sensitivity in juvenile chub mackerel in the range of ultraviolet (UV) to visible light (369-652 nm) by electroretinogram (ERG) using light-emitting diodes ...

Hydrodynamics of caudal fin locomotion by chub mackerel,Scomber japonicus(Scombridae)
Journal of Experimental Biology, 2002SUMMARYAs members of the derived teleost fish clade Scombridae, mackerel exhibit high-performance aquatic locomotion via oscillation of the homocercal forked caudal fin. We present the first quantitative flow visualization of the wake of a scombrid fish, chub mackerel Scomber japonicus (20-26cm fork length, FL), swimming steadily in a recirculating ...

Thirty novel microsatellite markers for the coastal pelagic fish, Scomber japonicus (Scombridae)
Journal of Genetics, 2012Scomber japonicus (Scombridae: Scomber) is a wide-spread pelagic fish in the warm and temperate transition coastal areas and adjacent seas of Atlantic, Pacific and northwest Indian oceans (Collette and Nauen 1983). Although there are few studies on development of microsatellite markers that provide useful tool to evaluate population genetic diversity ...
