First are the trawlers. They drop a huge net off behind their ship and drag it around, scooping up whatever is in front of it.
The second are pot catchers – which are the ships also used for crab. They drop off a huge “pot” (a wire cage) that is baited and the cod swim in to get the bait. I was told by one of the pot cod ship’s crew that cod caught this way are a better product as they are fresher (they don’t die in a net) and the flesh is in better condition (they are being mashed by thousands of pounds of other fish in the same net). To my eye, they definitely looked to be of better quality.
For a drawing of these methods, go to this link at the Trident web site:
The catcher ships come to the Independence to drop off their catch. It is stored in the ship’s hold in sea water to keep it VERY cool. A huge hose is put over from the Indy into the holds and the fish are pumped out.
At the first station, which is up on the deck, the fish are sorted with the messed up ones and any by-catch (fish who were in the wrong place at the wrong time) being put into different bins. Records are kept of all this. And yes, they are sorting during a blizzard.
