You choose an eligible dive site, then follow the Dive steps in order: check zone bonuses, move your diver, resolve the site’s bottom bonuses and any site effects — zone and bottom bonuses apply as listed on the board and card. (Rulebook p.6)

School tokens mark grouped fish on the ocean mat and are managed by the school rules, while discarded cards go to your personal discard pile unless a specific ability or schooling rule moves them elsewhere; treat schools and personal discards as separate game areas. (Rulebook p.9)
