I'm of the opinion that all mammal/avian slaughter, for whatever legal reason, should only be carried out by trained professionals in a controlled as possible enviroment.
Ritual slaughter is unavoidable but steps ensure thats as quick as it can be. The knife used there is as sharp as it can be and the edge unblemished. Particular attention is paid to that aspect. The hand is practised.
I'm not for fishing, don't like fish, but it's a blood sport, no matter how popular a pastime it is. As a source of free food in times gone past is understandable as an origin, but these days thats not the primary reason.
Fishing in industry can involve butchering while the fish are still alive. I accept that 200 miles out to sea the job cannot be involve waiting.
I've not been involved in culling or stalking for that matter, and Venison is a product we use so I can accept a need for us to kill them for food. I will say though that the sale of the animals life to an amateur, out for the weekend. should be discontinued and the job left to those who slaughter and are trained and licensed to do so.
The killing of foxes should also therefore be left in the hands of these professionals, with shooting being the preferred method. Running an animal to a horrific death is wholly unacceptable.
