Differential population structuring of two closely related fish species, the mackerel (Scomber scombrus) and the chub mackerel (Scomber japonicus), in the Mediterranean Sea.
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...
متن کاملBiometry markers of chub mackerel, Scomber japonicus Houttuyn, 1782, in the Adriatic Sea
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 ...
متن کاملGenetic Diversity and Population Structure of a Pelagic Fish, Jack Mackerel (Trachurus japonicus), Based on AFLP Analysis
Trachurus japonicus is a commercially important species in the East Asia, especially in China, Japan and Korea. We estimated the gene flow among six populations of T. japonicus from Chinese and Japanese coastal waters by using amplified fragment length polymorphism (AFLP) technology. A total of 531 bands were amplified for 81 individuals of 6 populations by 4 pair selective primers, 89.27% of w...
متن کاملLocomotion in scombrid fishes: morphology and kinematics of the finlets of the chub mackerel Scomber japonicus.
Finlets are small non-retractable fins located on the dorsal and ventral margins of the body between the second dorsal and anal fins and the tail of scombrid fishes. The morphology of the finlets, and finlet kinematics during swimming in a flow tank at speeds of 0.8-3. 0 fork lengths s(-1), were examined in the chub mackerel Scomber japonicus. Functionally, S. japonicus has five dorsal and anal...
متن کاملSteroidogenic and maturation-inducing potency of native gonadotropic hormones in female chub mackerel, Scomber japonicus
BACKGROUND The gonadotropins (GtHs), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are produced in the pituitary gland and regulates gametogenesis through production of gonadal steroids. However, respective roles of two GtHs in the teleosts are still incompletely characterized due to technical difficulties in the purification of native GtHs. METHODS Native FSH and LH were pu...
