Signal Crayfish in Buskin Lake

Signal Crayfish in Buskin Lake

Invasive species are plants, animals and insects that are “not from here”. Often they are also referred to as exotic, non-native, or invasive.  Once an invasive species becomes established, they often out-compete natural vegetation or animals, quickly take over a habitat, and can be quite destructive.

In Kodiak, Signal crayfish (Pacifastacus leniusculus) are not native to the Island and they have the potential to damage salmon habitat throughout Kodiak Island. The STK NRD is working towards learning more about and stopping the spread of this invasive species.

In partnership with the Kodiak Soil and Water Conservation District, the NRD staff are conducting surveys to assess the presence and abundance of crayfish in Buskin Lake, River, and tributaries. Please contact the Sun’aq Tribe of Kodiak at (907) 486-4449 or the Kodiak Soil and Water Conservation District at (907) 486-5574 with any information concerning crayfish sightings and the locations on Kodiak Island.
