The Mission: Research the effect Gobies have on the environment
Andrew Fallone, Charlotte Yoneyama, Iris Wong and Lucy Zhang set out to discover and find out about the local Goby in the TDCH river. Significant research was found and recorded about the ecology and biology of the invasive Goby.
Goby is a local fish that has established itself in North America that was originated in Europe and eventually discovered as an invasive species in Windsor in 1990. The supposed cause of this was the European ships transporting/dropping off the Goby in lakes. Unfortunately, the Goby started to take over and alter the Canada's environment and jeopardizing the population of many species. Since, the Goby were originally from Europe's environment, this gave goby the unfair advantage of adapting to a simpler and less complex environment. Due to this the Goby's eat and reproduce constantly causing them to take up approximately 100 fish per square meter in some lakes in Ontario; this causes them to infest the Great Lakes, watersheds and lake tributaries all across North America (including our school's lake that connects to the Humber River). Goby can be identified by their rounded snouts, their three horizontal, bumpy dorsal fins with two on their back and one on their stomach. They can also can be identified based on their behaviour; they spend time close to the lake bottom and can be seen eating smaller fish and fish eggs (they can be as small as fish eggs come to as big as the size of gravel). This causes populations of fish like the native trout to have their eggs snatched and eaten, reducing their population. They compete and eat fish similar to themselves like the sculpin fish species. They can also carry botulism type E and cause the fish population and bird population to decline. Overall, the Goby negatively effects the environment and overall native population in Canada. Hopefully, the government of Canada will take action and eventually drive out the invasive Goby species out once and for all.
