try wading out to the sand bars near the sky way bridge ,just keep an eye on where yo step sting rays are common here .if you do happen to see a sting ray stay still and you will be fine.
be sure to take your catch to shore though sharks ar not as common during day they are still around
don’t go out on the grass beds be for dawn and be off by dusk as many of the sharks are more active at nite
try the peir out to the ana marie island as well
as curtis said shrimp and squid are exelent bait
for fresh water you will need to go inland ,i believe there is a fishing area at miatica st park
