Prevent their spread
Spiny waterflea can spread by attaching to fishing equipment, including fishing lines and downriggers, anchor rope, and landing nets. Adult spiny waterflea will accumulate as a visible gelatinous glob on fishing lines and other equipment. While adult spiny waterflea will die out of water, under certain conditions the eggs can resist drying and freezing, and thereby establish a new infestation. They also can be unintentionally transported in bilge water, bait buckets, or livewells. Be sure to Clean, Drain, Dispose, and Dry!
