A) The result indicator formaldehyde (FA) in this species. B) During storage in 0 °C - 20 °C - 40 °C the amount of Formaldehyde increase rapidly. C) The level of formaldehyde concentration obtained in this species have been compared and discussed. D) Fluctuation in formaldehyde concentration in this species does not show fame pattern. E)The largest and shortest were found to be belong to silver pomfret and lizardfish, T.V.N test in this study used as a subsidiary test
