Aquarian Invasive Species In Canada

 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

 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

Zebra Mussels Zebra mussels are a form of mussels that come from the Dreissenidae, native to the Black Sea these mussels attach themselves on cargo ships and boats alike to take them across large bodies of water. Zebra mussels filter out algae from their habitat lessening food supply to native fish and decreasing the quality of its water, also largely known for their sharp shells that cut swimmers feet like razors.  CC: Bob Nichols; U.S. Department Sited :  https://www.invasivespeciescentre.ca/invasive-species/meet-the-species/fish-and-invertebrates/zebra-and-quagga-mussels/
