Fred Snyder - I doubt predation will affect gobies very soon. Zebras have lots of predators - sheephead and many more and they still increase in numbers. The best hope is that gobies will exceed carrying capacity and collapse like white perch did. We need to prevent new invasions. Fred Snyder - Zebras accumulate toxins by filtering water.
Gobies eat mostly zebras and gain the concentration.
Then smallies and others eat the gobies. Chatman - Unfortunately, I can see the Gobies and Mussels being as prevalent as Carp in the near future. Chatman - And, as wide spread. I've noticed lots of little gobies in the perch I clean, but those haven't accumulated much yet. The perch are still very clean.
