Marine BioInvaders -- Salem Sound Coastwatch

Potential Marine Invaders Identification
Marine Introduced Species Monitoring Resource Center
Prevention and early eradication of marine biological invaders are the most effective methods of managing introduced species. Therefore, we are asking the people who live, work, and play along the coastline to be on the watch for new arrivals. We want you to become the eyes on the water. SSCW has created ID cards for seven species that have the potential to invade the New England region. Early detection efforts are most concerned with these “Potential Invaders”. If you believe you have seen one of them, it is important to notify your monitoring organization, the MarineID and/or Hitchhiker Sighting Submission Form immediately. When a "Potential Invader" is found, volunteer monitors will need to have the sighting verified. Careful note of its location, a photograph, and/or a specimen sample should be taken. MIT Sea Grant under its Hitchhiker's Guide Program has developed excellent verification instructions. A taxonomic expert will then confirm the sighting.
