The timing of theront emission is highly variable, normally up to 28 days, but depending

The front end of the life cycle has the least variation of time for each stage and it begins with the trophont.

The stage where the parasite is attached to a fish is called a trophont. The trophont will spend three to seven days (depending on temperature) feeding on the fish and that is what you see symptomatically
