I believe the comment about dinks is absurd - NOBODY TARGETS dinks. What really happened is that these captains are so good they found schools of fish. The smaller fish tend to be more aggressive so they bite quicker. Many times the captains will figure out how to trigger the bigger fish by changing lures, adjusting the depth of their lures or tweeking the speed a bit. If they can't get the bigger fish to go they move on to find bigger schools or bigger fish that are actively feeding. Yes they try to get fish for their clients (to make them happy), but to think they sit on schools of dinks is rediculous when they can go catch big fish for the clients (and make them even more happy! duh!). Believe me these guys know how to catch big fish, they don't just circle around dinks all day - most of them I have fished with wouldn't want to catch dinks for fear of jeopardizing the future catch! They need to protect the fishery to continue to provide their clients with a resource going forward.
Don't be jealous if you hear some guys are catching 30 or 40 fish a day. It happens, I have been on some of the boats where that has taken place. Most of the fish were very good fish too. But it is what you don't hear that you should keep in mind. There are 10X as many boats that are not catching a bunch that won't say anything, cause there's nothing to talk about.
