A concerning discovery has been made in Eastern Canada, as experts have found an invasive species of fish known as the Oriental Weatherfish. This fish has the ability to survive out of water for short periods and can carry dangerous pathogens. The confirmation of this species in Nova Scotia by the Department of Oceans Canada has raised alarms among experts.
The Nova Scotia Invasive Species Council revealed in a statement on May 16 that the Oriental Weatherfish was spotted in a waterway in Nova Scotia, thanks to a vigilant individual who reported it to authorities. This marks the first sighting of this invasive species in the Maritimes region, which encompasses New Brunswick, Nova Scotia, and Prince Edward Island in Canada.
According to the council, the Oriental Weatherfish poses a significant threat to native ecosystems. They can diminish aquatic insect biodiversity, compete with native fish for food and spawning areas, and carry harmful parasites and pathogens that can affect both wildlife and humans. It is believed that these fish were introduced into the ecosystem through illegal release, as they are commonly found in aquariums.
The Oriental Weatherfish, also known as the Japanese Dojo Loach, is native to Eastern Asia and can grow up to 11 inches in length. These fish have been found to survive in oxygen-poor waters by using their intestine as an accessory respiratory organ. They are capable of enduring long droughts by burying themselves in muddy or silty environments. Despite their origins in Asia, this invasive species has been discovered in multiple states across the United States.
The resilient nature of the Oriental Weatherfish, as demonstrated by its ability to withstand extreme conditions, makes it a concerning presence in Canadian waters. Researchers and officials are working to address the threat posed by this invasive species to protect the local ecosystems.
