SK Aquatic Invasive Species Week 2020

Aquatic Invasive Species Canada

According to the DFO Many aquatic invasive species are already established in Canada, including:

  • European green crab
  • Vase tunicate
  • zebra and quagga mussels

Others threaten invading, like the Asian carps.

After habitat loss, aquatic invasive species are the second biggest threat to diversity in our planet’s ecosystems. Aquatic invasive species impact our aquatic resources by:

  • reducing biodiversity and habitat quality
  • outcompeting and endangering native species
  • costing a lot of money to aquatic industries
  • harming recreational activity

Many of Canada’s major aquatic ecosystems are vulnerable to invasion. For instance, species such as the zebra mussel and sea lamprey have permanently altered the Great Lakes ecosystem.

Aquatic Invasive Species Saskatchewan

The government of Saskatchewan has named May 24 to 30 Aquatic Invasive Species Awareness Week to show the threat of invasive species in the province.

Aquatic invasive species (AIS) include plant, animal, and invertebrate species threatening waterways and damaging habitats, along with power generation, irrigation, and municipal water infrastructure.

The province says it’s often impossible to eliminate AIS once they get into a waterbody. Examples include

flowering rush,

Prussian carp,

zebra mussels, and

spiny waterflea.

Saskatchewan monitors for aquatic invasive species and takes the following steps to prevent them from entering the province’s lakes and water bodies.

  • It is illegal to import, possess or transport high-risk aquatic species, including invasive mussels.
  • Provincial regulations allow conservation officers to inspect, quarantine, and decontaminate watercraft known or suspected to contain invasive species.
  • Federal regulations allow Canada Border Security Agency officers to check private and commercial watercraft entering the province from the United States.
  • The province raises public awareness and educates watercraft operators on risks and prevention.
  • Provincial watershed groups help to monitor for zebra mussels and assist with Clean, Drain, Dry education.
  • The province works with other agencies and jurisdictions to coordinate inspection and other prevention measures.
