The joy of fishing in Hawai'i is that there isn't really a season; it's good year-round. Sure, the bigger yellowfin tuna ('ahi) are generally caught in summer, and the coveted spearfish are more frequent in winter, but you can still catch them any day of the year. You can also find dolphin fish (mahimahi), wahoo (ono), skip jacks, and the king -- Pacific blue marlin -- ripe for the picking on any given day.
When choosing a fishing boat in the Islands, keep in mind the immensity of the surrounding ocean. Look for the older, grizzled captains who have been trolling these waters for half a century. All the fancy gizmos in the world can't match an old tar's knowledge of the waters.
The general rule for the catch is an even split with the crew. Unfortunately, there are no "freeze-and-ship" providers in the state, so, unless you plan to eat the fish while you're here, you'll probably want to leave it with the boat. Most boats do offer mounting services for trophy fish; ask your captain.
Besides the gift of fish, a gratuity of 10% to 20% is standard. It's up to the fisherman; use your own discretion depending on how you felt about the overall experience.
