[Fishing trip in Bangkok or nearby]

Thank you for your help, impulse. Still looking for any info about fishing trips at Chao Phraya if there are such trips.

[Fishing trip in Bangkok or nearby]

I'm supposed to help organizing a fishing trip in Bangkok or somewhere nearby as a 50th year birthday present. Requirement for the trip is that it should be authentic and possibility to be on a boat. I googled and found some options but all of them seemed to be quite similar. From Bangkok you take minivan to a nearby lake/pond where you do the fishing. It didn't seem to be so authentic but I guess that's not the purpose of those kind of trips. Anyway, could someone recommend these kind of trips? Does someone have personal experience of some company which organizes these trips?

The birthday hero and his family are staying at Ramada Plaza Bangkok Menam Riverside Hotel next to Chao Phraya. I couldn't find any fishing trips that would be organized at Chao Phraya. The purpose is not the get the next world record fish but to enjoy the day fishing with family. I could imagine that own long-tail boat from Bangkok to Ayutthaya and back along the Chao Phraya could be interesting trip. I know that there are cruises from Bangkok to Ayutthaya but never heard of fishing trips. Does anyone know are there such trips or could it be arranged?
