Lousy life

摘要

When most people think of salmon lice, they picture a parasite attached to the side of a salmon or a trout. However, before this occurs, salmon lice spend around two weeks of their life as passively transported plankton, moving with the currents of the sea.In the first five days or so, nauplii salmon lice do not have the ability to settle on a host and only do so after maturing into infective copepo-dids. They then have about ten days to chance upon a potential host.
