Invasive Crab Species Search and Identification- Asian Shore Crab

Using a bucket, net, and bare hands, the group searched the intertidal and spray zones to find the Asian Shore Crab invasive species. Many of the crabs were found under rocks and wooden planks. They were then catalogued based on visual characteristics to identify them to the correct species. The group also took pictures for more evidence of the species. The Vital Signs field guide was also used to properly identify the species. The distinct stripes made the Asian Shore Crab very easy to identify. Out of 48 crabs, 43 Asian Shore Crabs were found. Of those 43, 25 were male and 18 were female.
