Campaigners say fish farmed in England, Wales and Scotland face cruelty, with no repercussions for those who fail to meet welfare needs
The government has admitted there are no routine check-ups on fish welfare at slaughter after an investigation found no department would take responsibility.
Campaigners have said this means fish face cruelty with no repercussions for those who fail to meet their welfare needs, and have asked that fish are given the same oversight as other farmed animals.
