Fishing Maps

What are the best deep sea fishing guides that aren't super expensive in Corpus Christi? I am looking to go to Corpus Christi and do a little deep sea fishing with my dad and I was hoping to find someone with personal experience, or just more knowledge than me, about some good guides that don't cost more than 100 dollars. Im not looking for the trip to be more than 5-6 hours

Does anyone know of any good fishing spots in Corpus Christi area? I can't afford to pay for a fishing guide and I want my two sons to have a good time after we visit the aquarium.

How safe is Gulf Shrimp in terms of methylmercury and PCBs? I'm interested in hearing how safe shrimp is compared to cod, orange roughy, farmed salmon, wild alaskan salmon, etc. Is there an online guide that lists all fish according to their safety, especially in terms of PCB levels? I live in Corpus Christi, Texas, so is there an online source that can tell me about methylmercury/PCB levels in the Corpus Christi Bay? Thanks!!
