dc.description.abstract | The European sea bass (Dicentrarchus labrax) is a euryhaline marine teleost that can often be found in brackish and freshwater or even in hypersaline environments. Here, we exposed sea bass juveniles to sustained salinity challenges for 15 days, simulating one hypoosmotic (3¿), one isosmotic (12¿) and one hyperosmotic (50¿) environment, in addition to control (35¿). We analyzed parameters of skin mucus exudation and mucus biomarkers, as a minimally invasive tool, and plasma biomarkers. Additionally, Na+/K+-ATPase activity was measured, as well as the gill mucous cell distribution, type and shape. The volume of exuded mucus increased significantly under all the salinity challenges, increasing by 130% at 50¿ condition. Significantly greater amounts of soluble protein (3.9 ± 0.6 mg at 50¿ vs. 1.1 ± 0.2 mg at 35¿, p < 0.05) and lactate (4.0 ± 1.0 µg at 50¿ vs. 1.2 ± 0.3 µg at 35¿, p < 0.05) were released, with clear energy expenditure. Gill ATPase activity was significantly higher at the extreme salinities, and the gill mucous cell distribution was rearranged, with more acid and neutral mucin mucous cells at 50¿. Skin mucus osmolality suggested an osmoregulatory function as an ion-trap layer in hypoosmotic conditions, retaining osmosis-related ions. Overall, when sea bass cope with different salinities, the hyperosmotic condition (50¿) demanded more energy than the extreme hypoosmotic condition. | - |
