Does any culture make something like a hotdog, but made from seafood, rather than whatever hotdogs are made of?
Are you asking about a fish sausage, fish on a bun, or both? Fried fish sandwiches are common, and fish tacos are made from flaked or chopped fish, but there’s no casing and a tortilla instead of bun. There are sushi rolls that are similar, but again no casing and rice instead of a bun. Tuna salad sandwiches and other seafood salads on a hot dog roll are common also. Fish skin could be used as a casing as in gefilte fish, but I’ve never seen that served on a bun, could be though.
ETA: In a sushi roll the nori would serve as a casing, it’s not fish itself though.
ETA2: My son used to make squid tubes stuffed with crabmeat. I suppose if you ate one on a bun you’d have something like a hotdog equivalent.
Not a culture but there was an episode of Diners, Drive-ins and Dives that featured a made from scratch lobster sausage.
I worked at a seafood processor in Alaska that made salmon hotdogs. Quite good, salmon is fatty enough to pull it off, with the right spices and light smoking.
Here are some salmon hotdogs: http://www.groceryheadquarters.com/2012/07/wild-alaskan-smoked-salmon-franks/
Seafood sausage (Boudins De Fruits De Mer) is pretty common in French cuisine.
Not seafood, but fish: Whitefish Sausage is pretty common around here.
And I have recipes for all kinds of shrimp and scallop and lobster sausages. Not uncommon at all.
Fish sausage is big in Japan. Horrible plastic tubes of peachy pink guck! My kids like them.
Back in the 1950s here in the US they sold a canned fish hot dog called Tunies. Not good tasting.
I’ve seen seafood sausages (ground up raw fish, scallops, crab, whatever, stuffed in casings) once in a while in a fish store here. It’s very perishable, so not a lot is made at one time.
I could swear I’ve seen shrimp wieners here in Trinidad at a stand, shrimp burgers are also common at burger joints and grocery stores.
Sounds also like you describe a type of * guédille*.
Crawfish or shrimp boudin around the Gulf. It’s like a big spicy seafood bratwurst with rice in it too–very tasty! A lot of people dump the filling out of the casings after cooking, but I like to eat it in a roll, like a hotdog, dressed in slaw if you got it.
I believe there’s also a type of longanitsa made with fish, but I’ve never tried it. That’s a Filipino link sausage that’s sort of like a wetter, sweeter chorizo. Probably my favorite sausage next to cevapi.
(Ok, I’m a sausage addict.)
Ahh, brings back memories, that does. Actually, aside from the gawdawful fake coloring, they don’t taste bad, rather like fishcake (i.e. bland and only faintly fishy) if I recall correctly.

Koreans eat “eomuk”, which depending on how they’re made can be more like meatballs or more like hotdogs.
There’s a local hot dog shop that offers both veggie dogs and fish dogs in addition to the standard beef dogs. I’m told they taste pretty much like a hot dog.
