Experimental settings
In order to assess whether P. delicatissima have an impact on the
physiological performance of sea bass, a 45-day exposure experiment
was carried out in controlled conditions.
Juvenile sea bass (160 individuals) were supplied by the Gravelines
Marine Hatchery (Ecloserie Marine de Gravelines, France). For 14 days,
the fish were placed in two 160 L tanks (80 individuals in each)
filled with filtered seawater (1.2 μm Whatman GF/C; Table 1), and
acclimatized at 15 °C in a thermoregulated room under a 12 h:12 h
light:dark cycle.
