From Efish To Recfish - Progress Towards Developing An App That Engages Recreational Anglers As Community Scientists, M. Lisa Kellogg

Reports

The success of the Cornell Lab of Ornithology with eBird and its associated apps demonstrates the potential value in engaging recreational enthusiasts as community scientists through the use of a cell phone application (hereafter “app”). However, significant differences exist between the recreational angler community and the birding community making it necessary to further investigate the feasibility of engaging recreational anglers as community scientists using an app. The funds awarded through the VIMS Dean and Director’s Innovation Fund were used to: 1) assess the existing landscape of for-profit fishing apps and not-for-profit efforts to use recreational anglers as community scientists, 2) …

Contemporary And Future Distributions Of Cobia, Rachycentron Canadum, Dp Crear, Be Watkins, Vs Saba, Je Graves, Dr Jensen, Aj Hobday, Kevin C. Weng

VIMS Articles

Climate change has influenced the distribution and phenology of marine species, globally. However, knowledge of the impacts of climate change is lacking for many species that support valuable recreational fisheries. Cobia (Rachycentron canadum) are the target of an important recreational fishery along the U.S. east coast that is currently the subject of a management controversy regarding allocation and stock structure. Further, the current and probable future distributions of this migratory species are unclear, further complicating decision-making. The objectives of this study are to better define the contemporary distribution of cobia along the U.S. east coast and to project potential shifts …

Sublethal Effects Of Salinity And Temperature On Non-Native Blue Catfish: Implications For Establishment In Atlantic Slope Drainages, Vaskar Nepal, Mary C. Fabrizio

VIMS Articles

The distribution and further range expansion of non-native blue catfish Ictalurus furcatus in coastal waters throughout the United States Atlantic slope depend, in part, on the salinity tolerance of the fish. However, temperature-mediated sublethal effects of increased salinities on blue catfish biology are not yet known. We assessed the effects of salinity and temperature on growth, body condition, body composition and food consumption of juvenile blue catfish in a controlled laboratory experiment. Temperature and salinity had an interactive effect on blue catfish biology, although most fish survived 112 days in salinities up to 10 psu. At salinities 9 psu) likely …

2020 Annual Report Estimating Relative Juvenile Abundance Of Ecologically Important Finfish In The Virginia Portion Of Chesapeake Bay (1 July 2019 – 30 June 2020), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Trawl Survey provides crucial data to state, regional, and national fisheries management agencies, including the Virginia Marine Resources Commission (VMRC), the Atlantic States Marine Fisheries Commission (ASMFC), the Mid‐Atlantic Fisheries Management Council (MAFMC), and the National Marine Fisheries Service (NMFS). The MAFMC recognizes the juvenile trawl survey as one of the key predictors of Summer Flounder recruitment. Annual indices of juvenile abundance have been generated from trawl survey data for species of key recreational and ecological importance in the Virginia portion of Chesapeake Bay. These include Spot, Atlantic Croaker, Weakfish, Summer Flounder, Black Sea Bass, Scup, Striped Bass, White …

Dichotomous Keys: An Essential Tool For Fish Detectives, Jackson Martinez

Reports

Grades: 6-8 Subjects: Life Science | Biology

How do scientists identify an unknown fish?

In this activity, students will utilize a dichotomous key to identify unknown fishes from the Chesapeake Bay and will then characterize their trophic levels based on feeding preferences and adaptations. Students will gain an understanding of organism classification, trophic level interactions, and how fishes may play different trophic roles throughout their lives.
