anyone got any mangrove tips?

Was down in Fourchon this past weekend and with the weather so calm we decided to hit the first rigs off of the beach for some mangroves. In 2 days we landed 20 nice ones, but probably broke off three times that many. Also we would get them going and then they would go up to the live croaker, mullet, pogy, or whatever and just look at it and turn away. We were only in 50 feet of water and being that all I've got is a 22 foot Bay Boat I don't wanna go out any further than that, but the mangrove thing would be fun to do a few times a year, anyone got any tips on how to catch limits of these things? Every time I have done it, we are happy with 10 or so a morning
