European eel Anguilla anguilla to thermal stress
The changes in bacteriolytic and proteolytic activities of skin cathepsins L and B were studied Ž . in thermal-stressed European eel Anguilla anguilla . When fish were kept in 108C water, all activities increased to reach maximum levels at Day 8 with varying increasing rates of 3.0 Ž . Ž . Ž . proteolysis , 4.2 lysis of FlaÕobacterium columnare , 5.7 lysis of Vibrio anguillarum and 7.8 Ž . lysi...
متن کاملGenetic patchiness among recruits in the European eel Anguilla anguilla
Heterogeneity in genetic composition among recruits of marine species is mostly due to a large variance in reproductive success mediated by oceanographic processes. Temporal genetic variation in a population of the European eel was quantified over 2 time scales among glass eel (1) interannual samples (cohorts), and (2) intra-annual samples within cohorts (‘arrival waves’). A total of 789 glass ...

متن کاملTolerance of chronic hypercapnia by the European eel Anguilla anguilla.
European eels were exposed for 6 weeks to water CO(2) partial pressures (P(CO)(2)) from ambient (approx. 0.8 mmHg), through 15+/-1 mmHg and 30+/-1 mmHg to 45+/-1 mmHg in water with a total hardness of 240 mg l(-1) as CaCO(3), pH 8.2, at 23+/-1 degrees C. Arterial plasma P(CO)(2) equilibrated at approximately 2 mmHg above water P(CO)(2) in all groups, and plasma bicarbonate accumulated up to 72 ...
متن کاملOceanic spawning migration of the European eel (Anguilla anguilla).
European eels (Anguilla anguilla) undertake a approximately 5000-kilometer (km) spawning migration from Europe to the Sargasso Sea. The larvae are transported back to European waters by the Gulf Stream and North Atlantic Drift. However, details of the spawning migration remain unknown because tracking eels in the Atlantic Ocean has, so far, eluded study. Recent advances in satellite tracking en...
