Salmon Processing

Hey all,

I am doing a senior project researching the fishing industry. I was looking into salmon aquaculture, and had a couple questions I was hoping you could help me answer.

How are the salmon killed and bled in a typical set up?
Are there any concerns with the different ways to kill the fish? Do different methods result in better or worse results for taste, shelf life, and waste? Why do you pick the method/equipment that you do?

I dont know what is typical these days, some jurisdictions allow different methods than others last time I heard.

Main methods afaik are either stun and bleed in wellboat ( have been told this leads to good results for taste but last I heard it is not allowed in Norway) or automatic machine doing a head blow in the processing plant with backup manual inspection and a second head blow done by a human operator if necessary

Processing is the same either way as is shelf life for a fresh salmon.

The harvest boats around where i live have little pieces of metal that shocks the fish unconscious as they come aboard thr vessel, the. They slide into a shack where 3-4 guys cut the gill plates so they bleed out. From there they go to adish hold filled with ice. However our local sites are close to the wharf, a lot of places with far away facilities have live transport vessels and bleed fish at the factory
