My buddy was perch fishing Geneva marked what he thought was perch so he put his camera down to find massive school of something that looks like a small translucent squid hes Ben perch fish for yeas and never seen anything like it any one know what there are
Sounds as though it could be the freshwater jellyfish... the freshwater shrimp have been there for years and the perch do actively feed on them but the huge hoards of them don't really resemble jellyfish. A lot of times when you see large schools of perch under the ice and they won't readily bite that is what they are often feeding on (freshwater shrimp).....they sometimes come up puking them and stuffed full.
