Duran, Ayhan (Aksaray, Yazar)We investigated the effects of two different slaughter methods (sudden death and struggle death) on
catalase (CAT) activity and malonedialdehyde (MDA) levels in tissues of rainbow trout
(Oncorhynchus mykiss Walbaum, 1792). We analyzed a group of fish without waiting and other fish
groups after being kept in 8-10°C for 12, 24, 36 hours. Additionally, sensory analyses were studied by
a sensory panel consisting of experienced judges to sensory evaluation. We have been observed
significant increases (p < 0.05) in MDA levels and decreases (p < 0.05) in CAT activity of two groups
(sudden and struggle death). Using sudden death (unstressed) method, rainbow trout groups showed
good quality until to 36th hour, and sensory analyses of struggle death treated groups (stressed)
exhibited good quality up to 24th hour. Consequently, we got importance of storage temperature, time
and different slaughter methods on biochemical parameters and sensory analyses of some rainbow
trout tissues
