The parasite's life cycle is '''direct'''. The lice mate on the fish and the female then lays her eggs on surfaces or plants within the habitat. These then progress through a series of '''metamorphic stages''', each of which moults its exoskeleton in order to grow.

After 4 days the hatched crustacean will seek out a host fish to feed on.

After '''4 days''' the hatched adult crustacean will seek out a host fish to feed on.

The total life cycle takes 30-100 days and is temperature dependent. Eggs can undergo latency and delayed hatching if water temperatures are not suitable over Winter.
