Goldfish

 Welcome!

This is the first post relating to invasive species themselves, starting off with a well known fish: The Goldfish.

Goldfish are common as first pets in households across the world, but unfortunately some families flush them away before the fish has actually passed away. 

Goldfish can be more harmful to ecosystems than you might think, the reason they are so harmful is the way they feel, they come from the carp/minnow family and actually make the waters their in less susceptible to light and in turn decreasing the sunlight native plants have and need to survive. On top of that they also target fish eggs, larvae and native plants which escalates how bad they are for our environment.

Goldfish were brought from Asia and introduced as early as the 1600’s! As of today Goldfish are currently all across Canadian waters and even in Ontario. Goldfish can grow to massive sizes compared to their household brothers, apparently they can get as big as a football.

This is important to know for anyone who may have pet fishes, as improper disposal methods have harm to Canadian waters and some people may not be aware that there actually is a proper way to dispose of fish. 

Thanks for reading!!

    Thank you for sharing this. I'm always amazed to see these little orange creatures in our Ontario waters. :\

Asian Carp

 Asian Carp Brought to Canada by fishermen hoping to add more game fish, the Asian Carp has become a nuisance since the early 1900’s after discovering just how competitive this fish are, except these Common Carps were discovered to be terrible edible fish as they are bottom feeders and are incredibly boney. They’ve affected fishing industries and sport fisherman alike and eat everything they can fit in their mouth, once again just adding to how bad they are as a whole. They don’t create toxins like Round Goby’s but they are every bit invasive. Asian Carps sometimes reside in bodies of water that are un-checked as again they are bottom feeders, and can hide in cut off parts like golf ponds and more. Taken by: Stefan Amaral

Round Goby

 The Round Goby The Round Goby is a prominent invasive species swimming around Canada’s freshwater lakes, since 1990 gobies have spread competing against native bottom feeders for food and affecting sport fish by eating native fishes eggs. Gobies are a huge problem as they eat basically everything, including Zebra mussels! But just as good as it may seem, there’s been research linking a strain of botulism type-E to gobies as after eating Zebra Mussels the toxin is created and birds of prey and predator fish die out due to this botulism strain.  CC:  https://commons.m.wikimedia.org/wiki/File:Round_goby.jpg Furthermore here’s a short minute long video from Clevelands Aquarium of those up close, and closed captioned information about the Round Goby:  https://youtu.be/tEVUGfFw0Z4?si=IVI94mOc_m480hDr
