We ended up catching 5. None of them were very big, but we had fun none the less. I tried using senkos, surface lures, tube jigs, and had nothing happing. My son put on a bass coloured Rattlin' Rap and caught one immediately, so we switched to those and the seemed to do the trick. One largemouth as well, but he jumped at the kayak and threw the hook.
Thanks for the advice all.
