Three size groups of golden pompano were analyzed, including 600 - 800 g/fish, 800 - 1,000 g/fish, and 1,000 - 1,200 g/fish. The results showed that the total length and body depth of the 1,000- 1,200 g/fish group were in the range of 27.50-31.40 cm and 12.67-14.8 cm, respectively. The edible portion rate of the 800 - 1,000 g/fish group and the 1,000 - 1,200 g/fish were 53.36% and 53.34%, respectively, while that of the group 600 - 800 g/fish was only 50.09%. The proportion of non-edible parts of golden pompano was relatively high (over 45%), and the head occupied nearly 25% of the total fish weight. Golden pompano muscle contained 17.59% - 18.21% protein, a high lipid content of 8.37-9.9%, and 0.95 - 0.99% of ash. The initial total viable count in fish muscle fluctuated between 10 2 and 10 3 cfu/g, which was lower than that in the samples with skin (10 3 ÷10 4 cfu/g)
The amount of total volatile basic nitrogen in the raw material was 15.64 ± 0.27 mgN/lOOg, and the flesh pH was 6.27 ± 0.05.
