Embryonic development in allis shad Alosa alosa : A baseline for stress studies
Résumé
From experimentations in optimal conditions, we identified the main features of embryogenesis of allis shad Alosa alosa. We propose to use this outcome as endpoints to evaluate the impact of stressors on A. alosa embryogenesis in future studies. Eggs are spherical in shape, transparent and non-adhesive. Mass hatching occurs between 120 and 144 hpf at an incubation temperature of 20°C. Abnormalities of larvae were minor (1.10% of hatched individuals).
