This is a great article about the subject and it was sent to me by Al Hodges, thank you Al - Hodges. http://www.friendlyaquaponics.com/no-more-malaria/ I think everybody should read it. Now I'm thinking about replacing my tilapia with mosquito fish. I like to hear from someone who has the experience with a smaller aquaponic system than the one in the article.
Now that you mention it we didn`t have any mosquitoes eather here in the yard last year. My pond is full of guppies and they were constantly running around tin the duckweed. I never saw any wiggle tails in the pond.
