So I'm not a very experienced saltwater guy but the more I do it, the more I want to ditch the bass tackle and head to the salt. The family and I are heading to the keys in a few weeks and I'm looking for any advice y'all could give me for fishing around Marathon. We will have a 25' center console for the week. Im wondering if anyone can give me info on how/where to catch some bait? Also any advice on places to take the family to do some bottom fishing so we can catch some dinner? Or areas to troll for some bigger fish. Any advice y'all could give me would be greatly appreciated! Thank you in advance!

PS- I'd love to catch a tarpon and I hear Bahia Honda is the place to be. Any advice on tackle for the tarpon as far as line/hook size??
