Anyone with experience setting up spawning habitat for species that spawn in vegetation? I have several bodies of water supporting Brook Silverside where I can easily see breeding. Our study site differs in that the vegetation occuring in other areas is grazed down by an incredibly abundant crayfish population making so I see no evidence of the Brook Silversides breeding. I would like to setup up some sort of raft that can be floated some distance from shore so crayfish will not be at such high densities as to consume all the Brook Silverside embryos. Materials I use for breeding Goldfish and Golden Shiners is apparently not enticing for the Brook Silversides.
