Seafood is available at any time, but it is not necessarily fresh. Just got off the fishing boat, and the seafood just caught in the sea is relatively fresh. But now it's a closed fishing season, unless it's just bought from a marine farm, it's still fresh. Most of what is dumped from other places is the stock in the refrigerator pulled by refrigerated trucks. Eating Donghai seafood is not too bad, as long as you don't have diarrhea, don't drink more beer, and put more onion, ginger, garlic, vinegar and mustard, you can make do.
