“Bailing water” is the water that is used to pump the fish from the net into the fishholds. It is separated from the fish with screens and discharged over the starboard side after the fish have been elevated and are being dropped into the holds.
Refrigeration water is kept, ideally, at about 33 degees and is recirculated through the fish. This time of year it’s not too difficult to keep the refrigeration water cold, but in the heat of summer, every time you pump a bunch of fish, the temperature of the refrigeration water rises dramatically. Sometimes it causes a relief valve on the amonia refrigeration system to pop. You really want to be upwind when that happens. A face full of that stuff will get your attention…momentarily.
Then there is the “wash water” that is used to remove the fish from the boats. The wash water and residual “soluables” are hauled offshore and pumped overboard. It’s completely organic and completely legal, and it makes a hell of a chum slick!
Pogy fishing…it’s not for the weak of stomach!
