Comparison of volatile bases nitrogen (TVB-N) in Otolithes ruber and Argyrops spinifer stored under the ice (4°C)

This study was conducted to examine TVB-N changes in  O t o lit h e s r u b e r and  Argyrops spinifer stored under the ice (4°C). Changes of volatile nitrogenous bases after fishing on 2, 4, 6, 9, 11, 13, 16 and 18 days of storage in ice were measured by Kejeltac method. The results showed the average amount of volatile nitrogenous bases for Otolithes rub er was 25.731±7.07 mg per 100 g and in Argyrops spinifer was 20.88±5/53 mg per 100 grams. The TVB-N in Otolithes ruber at day 9 and day 13 in Argyrops spinifer were 25.2 mg per 100 g. The TVB-N after 19 days between two species Otolithes ruber and Argyrops spinifer significance different (P<0.05). The volatile nitrogenous bases after 19 days stored in Otolithes ruber was more than in Argyrops spinifer (P<0.05), But it certainly can not say it was any more corrupt and So along with other indicators such as volatile nitrogenous bases Trimethylamine and Formaldehyde are also measured. Otolithes ruber can be kept 9 under ice and Argyrops spinifer 13 days, after this time, the quality is reduce
