Goby Traditional Cache

This one is a quick park and grab. The container is a medicine bottle wrapped in camo tape. There is only a log and a small pencil inside. This can be a busy location during the work week, there are office buildings looking on, and construction occuring nearby. Please be discrete in your visit.

This park and grab is the fifth in my sealife series. 

The round goby is a small, bottom-dwelling, invasive fish, brought to N America in the ballast tanks of cargo ships. Round goby prefer waters with rocky and sandy bottoms. They feed aggressively on insects and other small organisms found on lake and river bottoms. Adult round goby eat large quantities of zebra and quagga mussels, and occasionally small fish and fish eggs. Their aggressive eating habits and ability to spawn several times each season have helped them multiply and spread quickly. 

• Round goby have reduced populations of sport fish by eating their eggs and young and competing for food sources.
• Researchers believe the round goby is linked to outbreaks of botulism type E in Great Lakes fish and fish-eating birds. The disease is caused by a toxin that may be passed from zebra mussels, to goby, to birds, resulting in large die-offs of fish and birds.
