Comparative study on the organoleptic quality of wild and farmed large yellow croaker Larimichthys crocea

To ?ll the blank in systematic study on the organoleptic quality of large yellow croaker Larimichthys crocea, we analyzed the organoleptic quality of the ?sh meat of wild, trash-?sh-fed, and compound-feed-fed large yellow croaker. Six ?sh(weight: 500 g) per group were sampled in the same period, and 89 indices of ?sh organoleptic quality were measured and analyzed. Results reveal signi?cant dif ferences in the body condition factor, skin/muscle color, ?esh texture, odor, and taste aspects between wild and farmed ?sh. Compared with the wild ?sh, farmed ?sh showed fatter body shape, whiter skin or muscle color, tender muscle, higher level of ?shy odor or volatile intensity, but lower delicious taste. In addition, compared with trash-?sh feeding, compound-feed feeding could improve the body shape, skin color, ?esh texture, and ?sh taste of large yellow croaker, but it also increased the ?shy odor. In principle component analysis and cluster analysis, the present study preliminarily established the systematic evaluation with multiple indices to the quality of large yellow croaker. It shall be helpful for the evaluation or improvement of the quality of farmed large yellow croaker.
