The current flow will also help clean them off. However this process is best done by the harvester in an onboard pre-rigor processing operation. This causes the least mess and also – if it bothers you – less of a fishy smell in the house. In short, the level of quality that can be achieved using these techniques in an at sea processing operation are unrivaled in the traditional industry model. The tube is removed and the fish is cleaned. Once a clear water stream is visualized, the pressurized water flow can be stopped, the belly cavity opened, and the entrails removed, followed by the same cleaning procedures used in the head-off process.

Once they have bled out, remove them from the bucket or cooler and put them in a clean cooler to chill. Therefore, pre-rigor Intravenous Pressure Bleeding will produce the ultimate bled-out salmon. Like barra, threadfin salmon are protandrous hermaphrodites - meaning they get the best of both worlds. This head-off method is best for a high production processing operation. This device will be made available for purchase by Webber Marine & Mfg., Inc. to salmon harvesters in the 2019 season. Slice through the fish around the gills from the bottom to the top of the fish to cut the main arteries. There are three subsets of pressure bleeding, they are as follows: As the title of this process states, the head is first removed from the salmon.
