The full rules for aquatic combat can be found on page 478 of the Pathfinder Core Rulebook. For ease of GMing, the most relevant rules are reprinted here.
• You’re flat-footed unless you have a swim Speed.
• You gain resistance 5 to acid and fire.
• You take a –2 circumstance penalty to melee slashing or bludgeoning attacks that pass through water.
• Ranged attacks that deal bludgeoning or slashing damage automatically miss if the attacker or target is underwater, and piercing ranged attacks made by an underwater creature or against an underwater target have their range increments halved.
• You can’t cast fire spells or use actions with the fire trait while underwater.
