Our project intends to identify diversity of sessile invertebrates found in oyster restoration stations in Gowanus Canal, Lower East River and Soundview Park in the Bronx by DNA Barcoding. We would like to compare diversity and population of sessile invertebrates from those three oyster restoration station. Our sampling research can determine the types of invertebrates and we can compare number of live oysters and number of other invertebrates that usually coexist with oysters. This is important because population size of other invertebrates in oyster habitats are indicator for growth and reproduction of oysters in oyster restoration stations. This way our DNA barcode research can give some data to oyster restoration stations, and based on the data, oyster restoration stations can make some improvements to increase oyster population.
