Welfare of farmed fish at slaughter

Abstract: Fish being fed in circular cages a few weeks before slaughter. Note the top net support to prevent predation by birds WVelfare of farm~ed fish at slaughter PETER SOUTHGATE AND TONY WALL FISH farming in the UK has grown rapidly over the past 30 years. The combined production of Atlantic salmon and rainbow trout in 1999 was approximately 200,000 tonnes, compared to 30,000 tonnes in the early 1970s. In most instances, productivity and good carcase quality go hand in hand with high welfare standards and, certainly… Show more

“…As some of the receptors in the present study responded to other noxious chemicals, this suggests that high CO 2 levels may be potentially painful in trout. This would account for the strong aversive behaviour and flight reactions observed when fish are placed in CO 2 saturated water (Yue, 2008;Poli et al, 2005;Southgate and Wall, 2001). Alternatively, these externally orientated CO 2 receptors and indeed those that were only responsive to CO 2 may provide the initial detection of elevated dissolved CO 2 so that the fish can make an avoidance response prior to those on the gill arches and orobranchial cavity being stimulated to elicit a cardiovascular reaction.…”

“…Stressors intensity and lasting determine the level of the acute stress exposure at death time. From the fish welfare point of view, the killing method should be fast, efficient in getting fish stunned and slaughtered without avoidable stress and pain (Southgate and Wall, 2001;HSA, 2005). The killing method can also be considered suitable if it is able to cause gradual unconsciousness without pain and stress.…”

“…Minimising pre-slaughter stress and the use of humane slaughter methods also improves product quality (Southgate and Wall, 2001;Skjervold et al, 2001;Robb and Kestin, 2002;Poli et al, 2005) …”
