As 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 (20-26 cm fork length, FL), swimming steadily in a recirculating flow tank at cruising speeds of 1.2 and 2.2FL s(-1)....

This study was performed to evaluate the effects of chicken breast meat on the quality of mackerel sausages. The mackerel sausages were manufactured by additions of 5%, 7%, and 10% of chicken breast meat. The lightness of mackerel sausages showed no significant differences between the control and addition groups. The redness increased in a dose-dependent manner, but the yellowness decreased sig...

The swimming kinematics of two active pelagic fishes from the family Scombridae were compared to test the hypothesis that the kawakawa tuna (Euthynnus affinis) uses the thunniform mode of locomotion, in which the body is held more rigid and undergoes less lateral movement in comparison with the chub mackerel (Scomber japonicus), which uses the carangiform swimming mode. This study, the first qu...

We aimed to understand the effect of biological interactions on distribution small pelagic fishes. Surveys were conducted during 2003-2019 using sea surface trawl nets in western and central North Pacific Ocean, covering an area between 143° E 165° W, estimate distributions 4 fishes: saury Cololabis saira , Japanese sardine Sardinops melanostictus chub mackerel Scomber japonicus anchovy Engraul...

we examined the diet and trophic level of sphyrna lewini in the gulf of california (gc) during 2001 and in the gulf of tehuantepec (gt) during 2005 using data from stomach content and stable isotope analysis of δ15n and δ13c. s. lewini diet was represented by pelagic and benthic prey species where the most important in weight was scomber japonicus (27.70±4.54%) in gc, while in gt it was auxis s...
