Maybe it's something about living in a land-locked state, but I'm not a fan of seafood, fish, or generally anything from the water. Generally, the first thing I think of in relation to seafood is the odor. Not just the seafood itself, but the odor around rivers, the odor of thousands of dead mussels, the odor of dead fish, etc.
Then there's the bones, skin/scales, and sometimes an exoskeleton. Lobster, crab, oysters, jumbo shrimp--just too much work for very little substance. Mostly waste products. Unlike my wife, I won't eat the head.
I did used to eat jack mackerel, and have had tina salad. On Fridays, they try to push salmon, and some other stuff on me. I have to scrape off the skin.
Growing up, we used to catch bowfin (a form of gar) at Mingo. Hard to catch, but the bones went down the middle. We also caught a bunch of blue cat and channel cat, along with some bass and sunfish. I guess I've cleaned too many fish. The odor stays on you for days.
