Killing methods, post-slaughter quality, part 2
All methods of slaughter have issues related to animal welfare. However, approaches such as death in air or bleeding without stunning have been particularly cited as unacceptable.
Health & Welfare
Slaughter methods can impact product quality. It is recommended that fish be fasted prior to slaughter to clean their digestive tracts. Instant killing minimizes the degradation of tissue quality. Immediate bleeding is more important than the bleeding method.

Health & Welfare
The methods used to kill fish depend on many factors, including fish size and species, aquaculture production system, fish quantity, market preferences and effects on product quality. Also, some methods may not be approved in some countries, as with the use of anesthetics and regulations concerning the ethical treatment of animals.

The author developed a protocol for the consistent measurement of catfish fillet color using a camera and properly calibrated software.
Health & Welfare
Authors developed a lexicon of sensory properties for pangasius fillets and examined the sensory characteristics of raw fresh and frozen catfish fillets as predictors of the sensory qualities of cooked catfish.
Intelligence
The most important factors in the loss of quality in seafood are nucleotide catabolism and glycolysis. The rates and pathways of nucleotide degradation vary with species and muscle type.
