Life cycle of Argulus coregoni. a a generalized scheme showing the key stages and sites. The larva hatches from the egg and attaches to a salmonid host, where it grows to adult. Copulation occurs on the host, after which the females detach to deposit eggs on a suitable substrate. b diverse behavioural interactions make the life cycle more complex, with more hosts being involved. Free swimming larvae attach to any available host, grow and then switch to more suitable hosts (salmonids). Adult males, the most mobile members of the population, may transfer between many salmonid hosts in the search for a mate. Gravid females deposit eggs in several different, consecutive clutches, returning to the host in between
