What kind of jobs do the Japanese do at fishing docks?

Question:

Besides fishing out at sea. Do they sell fish? Prepare it in a way? I read once that they go out in a small boat and dive for oysters (it was in a different time period a while back though) do they still do that? And anything else? How is this usually run? By whom? How do they prepare for these jobs? THANKS! ^_^

Answer:

Major portion of the fish they land on the harbors will be promptly transported throughout the nation. So, they do all kinds of works necessary for the shipment by refrigerated vehicles. Only a small portion of them are sold at their local fish markets.

Talking about "diving for oysters," you have a slightly wrong information. Production of oysters in oyster-cultivation farms built in calm inlets is pretty much systematized; they do not need to dive in the ocean to "harvest" them. I guess you are talking about women divers who are called "ama" collecting abalones in some small inlets in remote areas.
