... because it is a performance trait for which inter-individual variation may determine individual survival. The temporal stability of such variation is, however, largely unexplored. We quantified individual variation of various components of the escape response in a population of European sea bass...

... swimming performance by wild European sea bass in a constant acceleration test (CAT). Fish were challenged with four consecutive CATs with 5 min rest between trials. We measured maximum anaerobic speed at exhaustion ( U CAT ), gait transition speed from steady aerobic to unsteady anaerobic swimming ( U gt...

...Anthony P. Farrell; Michael Axelsson; Jordi Altimiras; Erik Sandblom; Guy Claireaux We examined maximum cardiac performance of sea bass Dicentrarchus labrax acclimated to 18°C and 22°C, temperatures near the optimum for growth of this species. Our aim was to study whether cardiac performance...

...Guy Claireaux; Christine Couturier; Anne-Laure Groison SUMMARY This study is an attempt to gain an integrated understanding of the interactions between temperature, locomotion activity and metabolism in the European sea bass ( Dicentrarchus labrax ). To our knowledge this study is among the few...

... of lordosis on the strain distribution in sea bass( Dicentrarchus labrax L.) vertebrae are assessed using finite element modelling. The response of the local tissue is analyzed spatially and ontogenetically in terms of bone volume. Lordotic vertebrae show a significantly increased strain energy due...

...Erik Sandblom; Anthony P. Farrell; Jordi Altimiras; Michael Axelsson; Guy Claireaux SUMMARY Cardiac preload (central venous pressure, P cv ), mean circulatory filling pressure (MCFP), dorsal aortic blood pressure( P da ) and relative cardiac output( Q̇ ) were measured in sea bass( Dicentrarchus...

... chain (MyHC) were studied during early larval development in rainbow trout and sea bass. Phosphoimager analysis of northern blots indicated that there is an optimum temperature for the RNA transcript levels of MRF and MyHC RNA in trout and in sea bass larvae. In the trout strain studied, the highest...
