Spiny Waterfleas confirmed in Shagawa Lake, Ely MN

Spiny waterfleas, an invasive species, have been confirmed in Shagawa lake as reported by the Ely Echo newspaper September 14.

Here are a few notable points made in the article;

Samples were confirmed by the MN DNR. Spiny Waterflea is a small planktonic crustacean that competes with small fish for food of microscopic animal plankton. The waterflea is not eaten by small fish.

Rich Rezanka, DNR aquatic invasive species specialist said "It is critical for anglers to remove spiny waterfleas from all equipment because their eggs can live out of water for more than 12 hours and be transported to other waters." When populations are high, anglers can experience frustration with masses of spiny waterfleas clogging fishing and downrigging lines and other equipment

Burntside lake, upstream from Shagawa, was designated infested in 2010. Shagawa and Fall Lakes will now be added to the list of infested waters. There is the likelihood of infestation spread.

Due to the discovery of spiny waterfleas bait harvest for any purpose is prohibited in Shagawa and Fall lakes.

Be sure to remove all aquatic plants, zebra mussels, and other prohibited invasive species, drain water from all water equipment including bait containers, drain bilges and livewells by removing the drain plug before leaving the boat landing.
