Annual Report - 2013 Data Collection And Analysis In Support Of Single And Multispecies Stock Assessments In Chesapeake Bay: The Chesapeake Bay Multispecies Monitoring And Assessment Program, Christopher F. Bonzek, James Gartland, Debra J. Gauthier, Robert J. Latour

Reports

Historically, fisheries management has been based on the results of single-species stock assessment models that focus on the interplay between exploitation level and sustainability. There currently exists a suite of standard and accepted analytical frameworks (e.g., virtual population analysis (VPA), biomass dynamic production modeling, delay difference models, etc.) for assessing the stocks, projecting future stock size, evaluating recovery schedules and rebuilding strategies for overfished stocks, setting allowable catches, and estimating fishing mortality or exploitation rates. A variety of methods also exist to integrate the biological system and the fisheries resource system, thereby enabling the evaluation of alternative management strategies ...

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell Apr 2014

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell

Reports

Proliferation of artificial structures to protect shorelines has introduced novel habitat to most coastal environments and fragmented natural habitats. These changes can result in disrupted connectivity, habitat homogenization, and altered estuarine landscapes, with uncertain implications for estuarine and marine faunal community structure and function. In estuaries, such as Chesapeake Bay, where soft-bottom habitat dominates and rocky shorelines are rare, the introduction of artificial rocky structure may enhance recruitment of species that are limited by the availability of suitable substrate including native and introduced species (Bilkovic & Mitchell 2013). There is a significant lack of empirical data on the types of epibiotic ...

Bonzek, James Gartland, Debra J. Gauthier, Robert J. Latour

Reports

Concerns regarding the status of fishery-independent data collection from continental shelf waters between Cape Hatteras, North Carolina and the U.S. / Canadian border led the Atlantic States Marine Fisheries Commission’s (ASMFC) Management and Science Committee (MSC) to draft a resolution in 1997 calling for the formation of the Northeast Area Monitoring and Assessment Program (NEAMAP) (ASMFC 2002). NEAMAP is a cooperative state-federal program modeled after the Southeast Area Monitoring and Assessment Program (SEAMAP), which has been coordinating fishery-independent data collection south of Cape Hatteras since the mid1980s (Rester 2001). The four main goals of this new program directly address ...

Supplementary Data And Analysis For Estimating Walleye Selectivity, Matthew W. Smith, John M. Hoenig, Neil Kmiecik, Mark A. Luehring, Melissa T. Drake, Patrick J. Schmalz, Greg G. Sass

Reports

This document has been issued as VIMS Data Report 61 and provides data tables and results of exploratory analyses conducted as part of the complete data analysis for Myers et al. 2014 published in the Transactions of the American Fisheries Society. Estimates of size- and sex-specific selectivity of fishing gear are important for making informed management decisions. We distinguish between capture selectivity – the relative catchability of the components of the population – and harvest selectivity, which is the combined effects of capture selectivity and the decision to retain or release a fish of a given population component. We used short-term recaptures ...

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay : Annual Progress Report : January 2013-December 2013, Mary C. Fabrizio, Troy D. Tuckey, Christopher D. Davis Jan 2014

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay : Annual Progress Report : January 2013-December 2013, Mary C. Fabrizio, Troy D. Tuckey, Christopher D. Davis

Reports

The 2013 Striped Bass juvenile abundance index was 10.94 and was significantly higher than the historic average of 7.04. Abundance indices from individual rivers varied compared with their respective historic averages, and significantly higher recruitment was observed in the York River (particularly the Mattaponi River). Average recruitment occurred in the other rivers. Increased catches of young‐of‐the‐year Striped Bass at upriver and downriver auxiliary sites suggest an expansion of Striped Bass nursery grounds in 2013. The evident increase in occurrence of young‐of‐the‐year Striped Bass throughout the tidal tributaries in Virginia further supports the ...
