I'm thinking of having some of the ships that drag acoustic arrays work at night, they should be able to triangulate the pingers pretty well, if they are still running.
I'm sure that any ship operating in the area has their passive gear listening 24/7. Dragging the fish can be done in most weather conditions, sometimes it needs to come in for feeding and a nap. Depending on your gear it may be safer and more efficient to bring said fish aboard while daylight is on your side.
