Oxygen consumption (M O2) was measured for gilthead seabream (Sparus aurata) during spontaneous and forced activities. During spontaneous activity, the swimming pattern was analysed for the effect on M O2 on the average speed (U), turning rate () and change in speed (DU). All swimming characteristics contributed significantly to the source of spontaneous(More)
Tail beat frequency as a predictor of swimming speed and oxygen consumption of saithe (Pollachius virens) and whiting (Merlangius merlangus) during forced swimming Abstract Oxygen consumption and tail beat frequency were measured on saithe (Pollachius virens) and whiting (Merlangius merlangus) during steady swimming. Oxygen consumption increased(More)
Decreased critical swimming speed and increased oxygen consumption (M O2) was found for externally tagged Atlantic cod Gadus morhua swimming at a high speed of 0Á9 body length (total length, L T) s À1. No difference was found in the standard metabolic rate, indicating that the higher M O2 for tagged cod was due to drag force rather than increased costs to(More)
Does temperature preference relate to the anaerobic capacity of Atlantic cod (Gadus morhua L.) with different haemoglobin phenotype? Abstract The effect of Hb-I* phenotype on white muscle lactate dehydrogenease (LDH, E. C. activity and buffering capacity was studied in Atlantic cod (Gadus morhua), acclimated and measured at temperatures near their(More)
While it is well known that O2 is directly removed from the water by skin and gill tissues of fish, the mismatch between O2 removal from water (O2 uptake; $$\dot{V}{\text{O}}_{ 2}$$ V ˙ O 2 ) and the O2 delivered to tissues by the primary circulation (O2 consumption; $$\dot{V}{\text{aO}}_{ 2}$$ V ˙ aO 2 ) has never been measured directly. Using data from(More)
This study reports the first results on telemetry of caudal differential pressure during spontaneous swimming activity in cod Gadus morhua and demonstrates that tail-beat pressure may be used as a predictor of activity and swimming costs of free-swimming cod. Tail-beat pressure was monitored using a differential pressure sensor on the caudal peduncle of cod(More)
