@jabberwookie87 Separate habitats have been a hypothetical solution for 20 years. It’s well demonstrated that the presence of nonnative sportfish leads to the eventual demise of native fishes. https://t.co/A2VPONi7Fj https://t.co/CMwamgUtxd

Thank you for highlighting the razorback sucker, Matt. If you dig a hole in the desert and fill it with water, these critters will spawn & recruit. Add a few nonnatives... failure. Separate habitats have been advocated since 2003 https://t.co/8oWS37s

2/3 ... as the process of manual removal of nonnative sportfish is not realistic in the long term. If you dig a hole and fill it with fresh water, RBS will recruit. But add ONE bluegill, channel cat, largemouth bass, striped bass, or flathead... https://t

@KFeilich @SolomonRDavid And they did/do reproduce in isolated habitats with native fish such as razorback sucker. See Minckley et al 2003 https://t.co/OXzsogZ6Sc
