Light is a key environmental factor that affects every life stage of crustaceans, especially during the larval stage. In early development, after hatching from the egg, crustaceans exist as larvae that float in the water column and are particularly susceptible to light exposure. This short review aims to compile existing findings regarding the effects of light on crustacean larvae. Overall, current findings suggest that a long photoperiod (more than 18 hours of light), higher light intensity, and white light may be particularly beneficial for the survival and growth of crustacean larvae. The collected information may be useful in optimizing rearing protocols in hatchery settings. However, further studies are needed to gain a more comprehensive understanding of how lisght affects crustacean larvae as a whole.
