Induced swimming in European seabass (Dicentrarchus labrax): effects on the stress response, immune, and antioxidant status.

ABSTRACT: Suitable swimming conditions can improve the growth and welfare of farmed fish. This study investigated how swimming affects immune and oxidative responses in European seabass (Dicentrarchus labrax), an important farmed fish species in Southern Europe. Thirty-two specimens were assigned into four experimental groups with the following conditions for 6 h: steady low (L, 0.8 body lengths (BL)⋅s^-1); steady high (H, 2.2 BL⋅s^-1); oscillating (O, 0.8-2.2 BL⋅s^-1) swimming speeds; and control non-induced to swim (C, < 0.1 BL⋅s^-1). The H group exhibited higher white blood cell counts and plasma cortisol levels compared to the C and L groups. However, innate immune parameters in plasma and skin mucus showed no differences between groups. Gene expression re
