..., the present study analyzed several fitness indices and characterized the immune response (in the blood, epigonal organ, liver, spleen and intestine) of temperate adult small-spotted catsharks ( Scyliorhinus canicula ) after a 30 day exposure to a category II MHW. The results indicated that adult small-spotted...

...F. Lou; N. A. Curtin; R. C. Woledge SUMMARY Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4±10.3 kN m -2 ( N =35 fibre bundles); this was significantly less than that produced by white fibres 289.2±8.4 kN m -2 ( N =25...

...W. Gary Anderson; Y. Takei; N. Hazon SUMMARY An increase in drinking rate of two species of marine elasmobranch fish, Scyliorhinus canicula and Triakis scyllia , acclimated to 80% sea water was observed following the introduction of 100 % sea water to experimental tanks. The drinking response...

...F. Lou; W. J. Van Der Laarse; N. A. Curtin; R. C. Woledge ABSTRACT Oxygen consumption and heat production were measured during contraction and recovery of isolated, white muscle fibres from dogfish ( Scyliorhinus canicula ) at 19 °C. The contraction period consisted of 20 isometric twitches at 3 Hz...

... the dogfish Scyliorhinus canicula . Heat production was also measured because the sum of work and heat is equivalent to the energy cost of the contraction (ATP used). These energy fluxes were evaluated in contractions with constant-velocity shortening either during stimulation or during relaxation. The muscle...

... increase was greatly reduced by covering the artificial muscle with a Teflon film. Experiments on living muscle from the dogfish Scyliorhinus canicula showed that muscle temperature was higher 2 min after a series of 20 twitches at 3 Hz if the muscle was not covered by Teflon than if it was covered...

... fibres isolated from dogfish Scyliorhinus canicula were used to characterize the force–velocity relationship of the contractile component (CC) and the stress–strain relationship of the passive, elastic component (SEC) in series with the CC. A simple model of the time course of crossbridge activation...

..., Scyliorhinus canicula (L.), from the Plymouth Marine Laboratory (Plymouth, UK) were used for all experiments. Fish were killed by decapitation followed by destruction of the brain and spinal cord. Bundles of fibres were dissected under saline from thin slices of the white myotomal muscle taken from...

...F. Lou; N. A. Curtin; R. C. Woledge ABSTRACT The energetic cost of activation was measured during an isometric tetanus of white muscle fibres from the dogfish Scyliorhinus canicula . The total heat production by the fibres was taken as a measure of the total energetic cost. This energy consists...
