... mackerel Scomber japonicus (20-26cm fork length, FL ), swimming steadily in a recirculating flow tank at cruising speeds of 1.2 and 2.2 FL s -1 . Thrust was calculated from wake measurements made separately in the horizontal (frontal) plane and vertical (parasagittal) planes using digital particle image...

...Kathryn A. Dickson; Jeanine M. Donley; Chugey Sepulveda; Lisa Bhoopat SUMMARY The effects of a 6°C difference in water temperature on maximum sustained swimming speed, swimming energetics and swimming kinematics were measured in the chub mackerel Scomber japonicus (Teleostei:Scombridae...

..., continuous gait powered by the aerobic myotomal muscle) and the net cost of transport ( COT net ) were compared at 24 °C in similar-sized (116–255 mm fork length) juvenile scombrids, an endothermic tuna, the kawakawa ( Euthynnus affinis ) and the ectothermic chub mackerel ( Scomber japonicus ). U max and COT...

... less lateral movement in comparison with the chub mackerel ( Scomber japonicus ), which uses the carangiform swimming mode. This study, the first quantitative kinematic comparison of size-matched scombrids, confirmed significantly different swimming kinematics in the two species. Ten kawakawa (15.1...

... 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 triangular finlets (the fifth finlet is a pair of finlets acting in concert). Slips of muscle that insert onto the base of each finlet indicate the potential...

... fins function as predicted by the homocercal tail model. According to that model, the caudal fin moves in a dorso–ventrally symmetrical manner and produces no vertical lift during steady swimming. To test this hypothesis, we examined the tail kinematics of chub mackerel, Scomber japonicus (24.8±1.3 cm...
