Hello

Dear researcher

Is there a way to remove the parasite spores in the hatchery center?

Last year, our sub-adult broodstocks became infected with this parasite; we had to remove them all and disinfect the entire hatchery center with chlorine.

Unfortunately, this year we faced this problem again and eliminated sub-adult broodstocks again.

These broodstocks were collected from farms; they were reared in the hatchery center itself !!!

- How is pollution caused?

- How can it be eradicated?
