Field Notes
Our group went on an amazing field trip to Reid State Park. The weather there was very depressing and cloudy, we thought it was going to pour. The first thing that our group and the other groups did was to pull the green crab trap out of the water. We saw lots of green crabs and also saw some native crabs like rock crabs, small lobsters, and a small fish, but there were no Asian shore crabs. When we got to Reid State Park it was still very cloudy, it was 68F. We caught 12 green crabs, but no Asian shores. The tide was low so we could find crabs more easily on the shore then in the water. We found them under rocks, in seaweeds, and in the water. Everywhere we looked there were Periwinkles in the water or on rocks. We also caught a native crab, but we let it back into the water instead of putting it in the bucket.
