Shrimps are complex, diverse organisms with a wide variety of characteristics. Diversity among shrimp species allows them to occupy several different niches and habitats. Three species of shrimp are found in great abundance in Randall's Island salt marshes. Two habitats at Randall’s Island are the unrestored and restored marshes. In this experiment, we are testing whether the restored marsh has a greater abundance of shrimp than the unrestored one; further, we aim to determine which species are present and their abundance.Using a seine net, we will collect samples from two marshes on Randall’s Island. We will later use these samples to run DNA tests to determine which shrimp species we have collected.
