Biometry 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 کاملTaxonomic review of Argentine mackerel Scomber japonicus (Houttuyn, 1782) by phylogenetic analysis
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...

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...
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...
