Greetings. I repost this once a year just as an FYI. Here is a quick and easy DIY tilapia egg tumbler design from the North American Journal of Aquaculture. Click on the link to read the paper: http://bit.ly/ZESh8I
This looks really easy to build. Thanks for the re-post. What kind of food do you recommend when the fry are at this stage? I am contemplating starting a spirulina tank and thought it would also work as a great nutrient.
Greetings. No food at first. They must absorb their yolk sacs before they will eat. Afterwards finely crushed tropical fish flakes or dedicated fry food works just fine ;-)
