Fishing from underwater domes

It makes sense to me that the best food in an underwater dome complex would be fish. Considering the massive amounts of aquatic life in the vicinity, it could work pretty well.

However, I can't think of how the people would actually catch the fish. They need to be able to breathe, so an airlock leading into a section of ocean wouldn't be useful (assume there is no underwater breathing technology nor submersibles available).

I've thought about some sort of net to catch them, but I'm not sure how the fish could be moved into the dome from there without flooding the place. If there were a way to catch fish on the sea floor (lobsters, crabs, etc.) easily, that would also work.

Assume the technology level when building the domes is that of today, but there will be no communication or supply deliveries from anywhere outside the domes (so nothing that would require extensive maintenance or consume too many non-renewable supplies).

Any ideas?
