New Funding Opportunity – South Atlantic Red Snapper Program Research Project 2

Questions About Previous Project Due: November 2, 2021

Questions Received and Responses

Question: On page 1, paragraph 2,  the Project 2 RFP states “Proposals should advance data collection for the distribution and density, Bayesian modeling, and close-kin mark recapture methods used in Project 1 which strives to generate three independent measures of absolute estimate of abundance by age class with accompanying measures of uncertainty for the entire South Atlantic Red Snapper stock.” And again in p.7 no. 1,, “Provide or support three estimates of the absolute abundance of age-2 and older Red Snapper in the U.S. South Atlantic region, and a measure of the uncertainty of this estimate using methods previously used and decreasing uncertainty with additional funding.” In Project 1 the objectives, below, lead to two independent estimates. Please clarify.

  • Estimate the distribution and density of Red Snapper across the U.S. Atlantic shelf from North Carolina through the Florida Keys with ROVs in unknown or unconsolidated habitats
  • Conduct genetic close-kin mark recapture (CKMR) analysis to estimate age-2+ Red Snapper population size
  • Develop a hierarchical Bayesian integrated abundance model to estimate age-2+ Red Snapper population size based on SERFS trap-camera and ROV survey data
  • Integrate/reconcile study results with the Atlantic Red Snapper stock assessment model

Response: The objectives from Project 1 lead to two independent estimates of abundance and the distribution and density on unknown and unconsolidated habitats which are requirements for the Project 2 RFP. These three elements are required. The RPP should state “two independent estimates of abundance and distribution” and has been corrected. Proposals should advance data collection for the distribution and density, Bayesian modeling, and close-kin mark recapture methods used in Project 1 which strives to generate  independent measures of absolute estimate of abundance by age class with accompanying measures of uncertainty for the entire South Atlantic Red Snapper stock.

About the Program

The South Atlantic Red Snapper Research Program supports the goal of generating an absolute estimate of abundance with an accompanying measure of uncertainty for the entire South Atlantic Red Snapper stock. This estimate will serve as an independent benchmark to inform the 2021 stock assessment and future stock assessments, as it will provide a metric of abundance on what the size of the stock is in the South Atlantic at the present time. The South Atlantic Red Snapper Research Program is sponsored by the Sea Grant programs of Florida, Georgia, South Carolina and North Carolina, with generous support provided by the NOAA National Marine Fisheries Service. Questions about the program should be addressed to Living Marine Resources Specialist, Graham Gaines.

South Atlantic Red Snapper Program Research Projects

Project 1 – Started March 2021

The objectives in the first project funded in this program, PI William Patterson’s Estimation of US Atlantic Red Snapper Abundance, include:

  • Estimate the distribution and density of Red Snapper across the U.S. Atlantic shelf from North Carolina through the Florida Keys with ROVs in unknown or unconsolidated habitats
  • Conduct genetic close-kin mark recapture (CKMR) analysis to estimate age-2+ Red Snapper population size
  • Develop a hierarchical Bayesian integrated abundance model to estimate age-2+ Red Snapper population size based on SERFS trap-camera and ROV survey data
  • Integrate/reconcile study results with the Atlantic Red Snapper stock assessment model

Project 2 – Announced October 2021

The goal of this grant opportunity, is to propose a framework for expanding the current Project 1 to augment the data that will be used for management advice of Red Snapper in the South Atlantic. Proposals should improve data collection for the distribution and density, Bayesian modeling, and close-kin mark recapture methods used in Project 1 which strives to generate three independent measures of absolute estimate of abundance by age class with accompanying measures of uncertainty for the entire South Atlantic Red Snapper stock.
