Effects of two culture models on the fresh quality of Oplegnathus punctatus

The effects of cage culture and industrial mariculture on fresh quality of Oplegnathus punctatus were studied. The hardness,springness,cohesiveness,gumminess,chewiness and recovery among the flesh of different body parts were evaluated and compared with the texture analyzer. And the p H,water activity and conductivity of the flesh from the fish under two models were determined as well. The results showed that there was significant difference between the two culture models( P 0. 05),while there were no difference in p H and water activity( P 0. 05). For the texture parameters,there were significant difference in hardness,springness and gumminess between two culture models( P 0. 05). While there was no significant difference in cohesiveness,chewiness and resilience( P 0. 05). After comprehensive analysis,it indicates that there is significant difference between the two culture models and generally the flesh quality from the cage culture is better than that from the industrial mariculture.
