Abstract: Three colorimetric reagents, Nash reagent (ammonia + acetyl acetone), AHMT reagent (4-amino-3-hydrazino-5-mercapto-1,2,4-triazole) and MBTH reagent (N-methylbenzothiazolinone-2-hydrazone) were compared for spectrophotometric determination of formaldehyde (FA) in fresh fish samples. The fish extracts were obtained through trichloroacetic acid (TCA) extraction of the fish samples. Post Hoc test analysis for multiple comparisons using Tukey HSD at p = 0.05 indicated that the amount of FA between the fish species differed from each other. All the three reagents have comparable accuracy and precision in determining FA in fish samples. Among the three reagents used, any of them could be used for FA determination in fish according to ANOVA, however, the MBTH reagent was the most sensitive and accurate followed by the AHMT and the Nash reagent.
