I just got back from the Burnet Rd Farmer's Market. There is a seafood vendor there now.....he trucks fresh, never frozen, seafood in from his contacts in Kemah. I bought four pounds of cleaned blue crab - they sell blue crab in two pound bags for $8. They also have fresh snapper (filet and whole), whole flounder, and shrimp with heads and without. Oysters should come next week. There were some other items that I can't remember. Everything smelled great.
So, if you need some fresh seafood, this is the spot.
