Apparently there’s not a lot to do in Yuma, Arizona.That’s the only explanation I can come up with for why someone would throw odd fish, including a dead shark, into one of the city’s canals - aside from stupidity of course.The first bout of fish dumping began back in September when authorities discovered some adult peacock bass in the Welton-Mohawk canal system near Yuma.  As peacock bass aren’t native to Arizona, someone had to have put them there. Why, isn’t known. What is known is that if left in the canals peacock bass would eventually cause all sort of problems. As Officer Richard Myers of Arizona Game and Fish explained, the fish could "… have detrimental biological consequences to our aquatic ecosystem by introduction of a non-native fish species as well as bring unknown diseases and parasites in our waterways."
