Muscle activity at slaughter: I. Changes in flesh colour and gaping in rainbow trout

High activity at slaughter is known to cause changes to the muscle biochemistry in terms of . muscle pH and adenosine triphosphate ATP content. This experiment looked at how the muscle activity may affect the flesh quality of fish. Electro-stimulation of a carcass immediately after death can be used as a model for high levels of muscle activity prior to death. This experiment . showed that electro-stimulation of 1.5 kg rainbow trout Oncorhynchus mykiss immediately after slaughter not only resulted in short times to rigor, but that the flesh colour was affected. The flesh . .
