Is there a social hierarchy among salmon fry?



  1. 0 Votes

    Salmon fry don’t appear to exhibit any kind of hierarchical behavior until they become juvenile salmonids, at which point they establish territories in their stream habitats. The larger individuals get the preferred habitats, meaning better protection and food possibilities, and thus better chance to continue growing larger. At this point a juvenile salmonid will move only to defend its territory to grab food, resting on the bottom at night.
