Some rockfish can live to be 100 years or older. Most Rockfish grow very slowly and don’t reproduce until they are at least 10 years old. Believe it or not, rockfish are aged accurately by analyzing the bones in their ears! Some species of rockfish are very territorial and may stay at a ‘home site’ for years. Rockfish often extend their dorsal spines and lean towards an approaching threat.  If this defensive posture fails to discourage an approaching threat, most rockfish will then head for nearby cover. Rockfish have air bladders which allow them to float motionless in the water column. This helps them to sneak up on prey very quietly to strike.
