Yesterday we setup to create hybrids between Orangespotted and Green Sunfishes with crosses being made each way. They will be compared to pure Orangespotted and Green Sunfishes grown under similar conditions. Conditions involve 0.25 acre ponds with cages containing adults and nest. Adult will be removed after 3 weeks to limit number of cohorts produced. Fish we acquired from hatcheries (state and commercial) were in exceptional condition. I bet first spawns will be realized within 24 hours.
Orangespotted Sunfish even in bags act differently from any sunfishes I have worked with. Males where attempting to setup nests in shipping bag. I have bred these critters before but never under more natural social conditions where those colors and displays actually come into play.
Extra fish (8 males and 2 females) were setup in a 75-gallon tank to observe breeding behavior. Observations will be on those. Females are good and ripe.
