KODIAK, Alaska (AP) – A team of biologists is surveying a lake on Kodiak Island for crawfish, an invasive species that has been observed in higher frequency over past several years.

The Kodiak Daily Mirror reports the biologists working for the Sun’aq Tribe of Kodiak began the three-year project this spring, analyzing the distribution, movement and diet of crawfish in Buskin Lake.

Documentation of the crawfish began in 2002. Biologist Kelly Krueger says evidence then appeared in 2015 that indicated the population was breeding. The tribe since has been making efforts to study if the population is increasing and if the species is affecting native wildlife.

The survey is being funded through a $200,000 grant from U.S. Fish and Wildlife Service.

The team will continue working on the project into the late summer.
