Big school of greater amberjack

Do you know why fish form schools? 

  • The main reason is to protect by grouping into a tight, regimented pattern, the fish minimise their chance of being picked up by their predators. 
  • The second is to enhanced foraging success, because the number of eyes looking for food increases  and when one fish demonstrates feeding behaviour, the others follow.
  • The last reason is to increase the success of finding a mate, improve communication and reduce stress.
