This study has conducted to evaluate the effects of aquamin-T on fungi control, ratio of eyed eggs, hatching rate and survival of rainbow trout eggs during 29 days. Each treatment was triplicates into Californian troughs which contained 1650 eggs. The control treatment without disinfectant (1), UV with using of 60w lamp (2) and 2, 3 and 4 g aquamin-T per liter of water (3 to 5). During the experiment, fungal infection, ratio of eyed eggs, hatching rate and survival were measured. In the end of experiment, results showed significant differences among treatments. Fungal infection in 4g/L Aquamin-T treatment was significantly lower than other treatments (P<0.05). 3g/L Aquamin-T treatment had a higher ratio of eyed eggs, hatching rate and survival other than treatments. The results of this study showed that 3g/L of Aquamin-T is a useful and effective for the disinfection of rainbow trout water hatchery and it is suggested that further studies be conducted with Aquamin-T on other fish egg disinfectant.
