Abstract

A study evaluating the effects of iodine treatment on the hatching success of turbot eggs wascarried out. A hundred, 500, 1500 and 3000 ppm iodine treatment were performed for 10minutes. The treatment with 3000 ppm iodine presented lower hatching percentage (70.0±6.08%). The control group (97.6 ±1.42%) and disinfected with 100 ppm iodine (91.3 ±4.04%)resulted in slightly higher hatching percentage, and significantly different from the otherdisinfected groups (P < 0.05). The control group and disinfected eggs with 1500 and 3000 ppmiodine were statistically significant in abnormality (P < 0.05). Zero-day-old eggs, 1-day-oldeggs and 3-day-old eggs were treated with a dose of 100 ppm iodine for ten minutes.Differences in abnormalities between 0-day-old eggs (early morula stage) and 1 and 3 day-oldeggs were statistically significant (P < 0.05). In conclusion, 100 ppm iodine appeared suitablefor disinfecting turbot eggs if treatment is applied at the early morula stage.
