YP are doing great. They spawned this spring for the first time. I am not sure if any of the fry made it but time will tell. I have seen a few of the YP from the leftovers from the heron and they are about 10 inches long.
When I pulled up the diffuser this spring in the bucket was one small SMB. He didn't grow much over the winter. ( I put them in late last summer ) I know I have a few that are about 8 inches long but many in the 5 to 7 inch range.
Thus far, I havent had any fish kill. My fatheads are holding their own against the YP and SMB. I did add 2 more pounds in of the FH right around spawning time to help build up what I lost over the winter. I now see clouds of tiny FH fry around the surface.
I have been adding crawfish this spring and have had good luck with them. (Yesterday i found a 7 inch one in the middle of the yard about 200 ft from the pond raising his claws at me. In the pond he went again)
I have tons of frogs and tadpoles and blooms going all the time. The floating Island looks naturalt his year and except for the fact that it moves around based on where the bubbles push it and the length of the cord tieing it to the diffuser you could not tell it is not a real island. The minnows and small fish love the underside of it where the roots come through. The frongs love the wet part of the top of the Island and the wood ducks and others love ladning on it and not being near shore.
All in all I am glad I took things slow and build up the eco system the way I did and the way I was told to here. It is very nice now.
All that is left this year is to enlarge it more and provide some more shallow areas for spawning for all of the fish. Wife willing of course!!
