- •
In aquaculture, incubation of eggs under high density leads to hypoxia and elevated ammonia concentration.
- •
Knowledge of the effects of these stressors on the viability of marine species is very limited.
- •
Red snapper embryos and newly hatched larvae were exposed to different levels of hypoxia and elevated ammonia concentrations.
- •
Moderate ammonia concentration (0.37 mg UIA-N L-1) or hypoxia (3 mg DO L-1) affected the survival of embryos and larvae.
- •
The tolerance to hypoxia and elevated ammonia concentration varied significantly among spawns.
