In the news: Genetic mapping may help solve the invasive lamprey dilemma

Posted March 25th, 2013 in Aquatic Invasive Species
Genetic mapping of sea lamprey DNA may provide researchers some insight into controlling the invasive species, and may even lead to human health benefits.

 

From the Great Lakes Echo: 

“Sea lamprey – unlike the silver and American brook species – come from the Atlantic Ocean, accidentally introduced to the Great Lakes through shipping canals.

Like the native silver lamprey, sea lamprey are parasitic, with sharp teeth and a sucking disc mouth that allows them to feed on the blood of host fish. Also like the silver lamprey, they are harmless in their early stages of development. 

Sea lamprey spend the first four years of their life as larvae in the soft bottom and banks of lakes or streams, according to the New York Department of Environmental Conservation. 

As they mature, they change into the harmful predator threatening the Great Lakes today, said Yu-Weng Chung-Davidson, a senior research associate on Li’s team.”

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.

Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.

The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.
