For the last 8 years, myself and a group of trained citizen scientist have been monitoring marine invasive species on docks, rocky shores, and tide pools as part of the Marine Invader Monitoring and Information Collaborative, or MIMIC.

European Rock Shrimp and penny scaleWhile monitoring for invasive species this week with the MIMIC program, I came across a species of shrimp I have not seen in my 4 years of monitoring at this site. The species is Palaemon elegans, the European Rock Shrimp, and is quite different in appearance from our native species of "estuarine" shrimp, Crangon septemspinosa (sand shrimp) and Palaemonetes pugio (grass shrimp).

Marine InvasivesThe Marine Invader Monitoring and Information Collaborative (MIMIC) is a network of trained volunteers, scientists, and state and federal workers who monitor marine invasive species along the Gulf of Maine. The collaborative provides an opportunity for the general public to actively participate in an invasive species early detection network, identify new invaders before they spread out of control, and help improve our understanding of the behavior of established invaders. More than 100 volunteers are monitoring 38 sites in Rhode Island, Massachusetts, New Hampshire, and Maine.

Marine invasives rapid assessment team at work in Wells HarborLast Friday a science team marched to Wells Harbor and began a rapid assessment of marine invertebrates on and around the dock. The taxonomic specialists from MIT, Sea Grant, and the Massachusetts Coastal Zone Management Program were joined by Reserve research director Michele Dionne and associate Jeremy Miller, who facilitated the Wells Harbor survey.
