New paper out describing method for tagging fish Satellite tags are a method to track the movements of animals in the ocean. However, they have mostly been used on larger animals, due to the relatively large size of the tags. In a new paper (LINK), a method is described using a new generation, and smaller, satellite tag on adult sheepshead, a relatively small species of fish for this approach. Andrew and Jim are coauthors on the paper, with colleagues from UNC and NCSU. |

New project on the trophic impacts of invasive blue catfish Blue catfish are invasive within many systems along the Atlantic coastal plain, where they can become one of the most abundant predators. Their broad diet, long life span, and large size means they have the potential to negatively impact native species, including important resource species. The Fisheries Lab, along with collaborator Fred Scharf (UNC-Wilmington), have been awarded funds by the NC Commercial Fishing Resource Fund to estimate trophic impacts (predatory and competition) of blue catfish in the Albemarle Sound ecosystem. |

How do fish respond to oyster sanctuaries in Pamlico Sound? This summer, CSI hosted a group of undergraduate researchers for an NSF sponsored program. The Marine Fisheries Lab worked with one of these students, Diandre' Richie, to assess how fish abundance might be enhanced at oyster sanctuary sites in Pamlico Sound. We used acoustic imaging technology to measure fish density and size distributions at many positions inside and outside of two different oyster sanctuaries. We found that mean fish densities were over twice as high in sanctuaries compared to the surrounding area. See Diandre's poster here (LINK). |

JULY 2022 Chloe joins the lab to research the parasite that causes black gill Black gill is a condition caused by a parasite, which infects multiple species of shrimp in the southeast U.S. In other states, this parasite is thought to have negative consequences for shrimp populations, which are of major economic and ecological importance. However, the dynamics of this host-parasite relationship have not been investigated in North Carolina. Chloe will be using microscopy and genetic markers to determine seasonal and spatial patterns of infection in Pamlico Sound, for grass shrimp, brown shrimp and white shrimp. Her project has already received attention, as the Southern Shrimp Alliance awarded Chloe with funds to help support her work. Chloe will be co-advised by Jim and April Blakeslee. |

Caid participating in study on Atlantic tunas Correctly identifying closely related species from recreational and commercial fisheries catches is important for effective management, because it affects the data that analysts use to assess fish stocks. Caid is helping researchers from Michigan State University, who are using genetic markers and fish morphometrics to classify tuna species. Caid is taking pictures of tuna that are landed along the Outer Banks. |

Andrew accepted as a Coastal Community Environmental Data Scholar The Coastal Community Environmental Data Scholars (CCEDS) program is an NSF funded Research Traineeship for graduate students at ECU. The goal of this 3-year program is to enhance data science based approaches among graduate students, and to engage students in stakeholder involvement and communication with the public. Andrew will be applying his use of sonar technology in coastal inlets to the CCEDS program. Coastal inlets represent areas of intense overlap between human-use and marine organism dependency, but human-ecosystem dynamics are poorly understood in these areas. |

Diandre' Richie examining habitat enhancement of oyster sanctuaries The Coastal Studies Institute is hosting undergraduates from across the U.S. to participate in summer research as part of the REU program. Diandre' Richie, a junior from the University of North Carolina-Wilmington, will be working with the Fisheries Lab to measure how fish densities and lengths are enhanced by oyster sanctuaries in Pamlico Sound. He will be using acoustic imaging sonar to collect novel data in these artificially enhanced habitats. |

Dylan Whitt to study seagrass assemblages The fishes and invertebrates that use seagrass habitat in the northern Pamlico Sound region have received little scientific attention. However, this area might be unique among seagrass habitats in North Carolina, because it is adjacent to the only coastal inlet that is north of Cape Hatteras, which is a major geographic dividing line among marine fauna. Dylan Whitt is a senior biology major in the Honors College at ECU. For his undergraduate thesis he will be examining spatial and seasonal species dynamics in seagrass habitat by conducting a monthly beach seine survey with the Fish Lab at CSI. |

Community outreach at CSI Open House The Fisheries Lab participated in the Open House event at the Coastal Studies Institute this month, where the public was invited to tour the facility and meet researchers at CSI. Our group spoke with over a hundred interested people from the community. We had three demonstrations that described the use of different marine acoustics technologies in marine ecology, including an area were folks could see live acoustic imaging video (picture at left). In the lab, we also had a live critter cam, where kids could see live grass shrimp and juvenile blue crabs under magnification. |

Do oyster farms have enriched soundscapes? As part of an independent research project during the summer of 2021, Ray Delvillar recorded the soundscapes of five different oyster farms in Pamlico Sound and compared them to nearby control areas. After filtering out a great deal of boat noise, he found that there is a lot more biological activity around oyster farms, compared to controls, including evidence for spawning aggregations (silver perch) and nesting behavior (oyster toadfish). See his poster here (LINK). |
