Title: Developing DNA Methods to Monitor Invasive Species and Biodiversity in Estuaries - NERRS/NSC(NERRS Science Collaborative)
Status: Completed
Abstract:

This project tested the use of eDNA methods to identify fish communities, assess biodiversity, and detect invasive crabs in different types of estuaries and connected streams. Samples were collected at Apalachicola, Great Bay, He’eai, Hudson, South Slough and Wells Reserves in 2018 and 2019. The project deployed two methods to analyze DNA in water samples: metabarcoding that identifies a wide range of species, and digital droplet Polymerase Chain Reaction (ddPCR) that identifies a single target organism. The team conducted baseline community assessments for fish at five reserve sites and conducted a survey of anadromous fish in a tributary stream at the sixth reserve. The project found that fish community and biodiversity assessments are well suited to eDNA applications, while invasive crabs are much harder to detect because they

do not shed much DNA. The project developed protocols and recommendations for the collection, filtering, and extraction of eDNA samples at estuarine sites, and provided information which will support the design of sampling programs for fish communities.

Purpose:

Biological monitoring programs are essential foundations for effective management of estuaries and coasts, but they can be expensive to conduct and methods such as the capture of living organisms may be traumatic for some target species. Advancements in DNA methods now make it possible to identify the organisms in an area by the DNA they leave behind, but there are relatively few proven sampling protocols and example datasets from estuaries. This project established a Collaborative Learning Community of Practice around Environmental DNA (eDNA) sampling within the National Estuarine Research Reserve system and explored the potential for eDNA to support estuarine management. Scientists and staff from six reserves worked Dataset Description: eDNA data from 6 NERRs NERRS Science Collaborative collaboratively with researchers, resource agencies, and a technical advisory team to design and

implement eDNA-based monitoring protocols for specific issues and species of interest in estuarine ecosystems.
