Its average length is only about one centimeter, but its long tail spine (70% of animal's total length) makes it easily distinguishable from other invertebrates and zooplankton. The tail spines of the spiny water flea hook on fishing lines and foul fishing gear. However, due to the life history of the waterfleas, these species may have arrived to the Great Lakes as resting eggs (fertilized eggs that are shed in Autumn to “rest” in the lake bottom sediments and hatch the following Spring). The fishhook waterflea has three pairs of barbs on the tail. Due to the long tail spines, spiny and fishhook waterfleas get tangled on fishing line and foul the fishing gear. Each simulation was designed to replicate slow trolling. The upshot of the research is that anglers now know they can take relatively simple steps to help slow the spread of spiny water fleas. Eggs are released and enter diapause for the winter.3 Economic Impacts: In high numbers, spiny water fleas can catch on fishing line, fish nets, and trawls.

Individual spiny waterfleas are difficult to see but they often collect in masses on fishing line, downrigger cables, anchor ropes, and other tackle. “It’s commonly believed that human recreational activity is the primary vector of spread for spiny water flea, but little is known about the specific pathways they take,” added Dr. Valerie Brady, co-researcher.
