Nope. They need very very small live feed until they can even fit brine shrimp in their mouths. If you want to go to the trouble of an algae culture feeding and producing zooplankton etc. etc. it can be done but not worth the trouble when you can get Mother nature to do it for you unless you are a commercial producer.
There are so many eggs from even one perch I wouldn't worry about survival if that is your concern.
When I went to collage I worked for my uncle. He would raise Angel fish for the home aquarium. We would ship 1500 about the size of a quarter each week. These fish were of the cichlid family. We would hatch their eggs out and feed them brine shrimp as their first feed. I would expect that their mouths would be much much smaller than perch fry.
Well aired water with a touch of blue die to keep the fry shaded. They would eat the brine shrimp till they could take in flake then pellet feed.
Thoughts?
Cheers Don.
