What you can expect on a day out depends of course of the season.
Barracuda, African Pampano, Cobia, Jacks, Trevally, Queenfish, King Mackerel/Spanish Mackerel, Snapper, Grouper, Sweetlips , Sharks, Sailfish, Marlin, Skates and Rays.

  Day fishing
A typical day depends on the tide and of course the sea conditions.
Often we start just outside Royal Cliff or one of the many reefs out from
Asia hotel and Koh Larn. Depending on the success, weather and tide, we head out to Koh Pai, Koh Luam and/or Koh Lin. This is a 2 hours beautiful ride. We normally use wobblers or skirts on the way out.
If there's season for it, we go for Marlin, Sailfish and Kingfish with
 

balloons and live bait. Then it is bottom fishing with live and dead bait. Most common is Queenfish, Barracudas, Trevally, Jacks, Pampano, Cobia, Snapper and Rays. We normally don't get any sharks out there. They are usually caught in Pattaya bay and around Koh Lin (or Koh Kram outside Bang Saray).

  Night fishing
We often head out to Koh Krok next to Koh Larn to go for Barracuda and Sharks. If the condition is right, it is normally Cobia
and Snapper out there as well.
Depending on the wind and sea we head out to Koh Lin or behind Koh Luam to get to the deeper waters (50 meters). Grouper, Snapper, Cobia, Barracudas and Rays up to 250 kg can be caught there.
