- Description
- NOTICE OF INTENT TO NEGOTIATE A SOLE-SOURCE CONTRACT EXTENSION National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS) hereby gives public notice of the intent to negotiate a sole-source contract pursuant to the authority of Federal Acquisition Requirements (FAR) 13.501, for a one-year extension to contract 1305M219PNFFN0238 with Commonwealth Scientific and Industrial Research Organization (CSIRO). Southeast Fisheries Science Center (SEFSC) has been to conducting a genetic mark-recapture experiment (termed close-kin mark recapture) of Atlantic bluefin tuna to estimate the absolute abundance of fish spawning in the Gulf of Mexico with CSIRO. So far, the project has advanced in three phases over a period of four (4) years. Phase 1 (FY2019) involved genotyping larvae and adults collected from the Gulf of Mexico and Mediterranean Sea from 2016 and 2017 to measure the relatedness between individuals. This was important to estimate how many spawners can be identified from the genetic information of their offspring (i.e. parent-offspring are termed close-kin). This approach served as a method for tagging individuals known to have recently spawned in the Gulf of Mexico, without the need to handle the large, mature fish prior to capture by fisheries. Phase 2 (FY2020) has genotyped additional individuals from both natal populations (Mediterranean and Gulf of Mexico) and developed statistical models to assign individuals to a stock of origin. This information was critical to accurately assign catches to a spawning population, and principal for accurate stock assessment. Phase 3 (FYs 2021, 2022 and 2023) has genotyped all available fish per year up to 2023 collections for parentage assignment (spawner close-kin mark-recapture) which allowed for the estimation of absolute spawner abundance, and a time series of absolute abundance for the entire study period (2016-2023). An additional year of sampling and analysis has been requested by SEFSC to begin in September 2023.
