Working group towards a better understanding of fish contribution to carbon flux - PI: Grace Saba (Rutgers University)
Objective: We will begin to tackle the issue of the carbon flux contribution from upper trophic levels. This contribution is completely ignored in present-day carbon budgets and is likely significant due to high abundances of fish in certain regions (i.e., coastal zones, mesopelagic) and previous documentation of high fish contribution to total carbon flux. Products of the working group meeting will include: 1) a review paper on fish carbon flux with a concluding section on research priorities identified during the meeting; and 2) a science plan for submission of collaborative proposals to funding agencies to expand our knowledge of fish contribution to carbon flux, ranging from single-species laboratory experiments to incorporating fish carbon estimates into regional and global biogeochemical models.
- Synthesize the existing research on fish carbon flux
- Recognize challenges in measuring fish carbon flux and discuss approaches to resolve them
- Develop research priorities to fill in the large gaps in understanding fish carbon flux
- Identify opportunities to obtain resources needed to move this research forward
OCB workshop report: Towards a better understanding of fish contribution to carbon flux
This workshop, held March 4-5, 2019 at Rutgers University, was attended by 14 researchers from 11 different institutions. The workshop focused on synthesizing the existing research on fish carbon flux, discussing challenges in measuring fish carbon flux, and determining approaches for estimating fish contribution to carbon flux on variable scales. Presentations and discussions were specifically targeted toward best approaches for determining: fish biomass on regional and global scales, relative amounts of carbon forms produced from fish (i.e., release of sinking fecal pellets, excretion of particulate inorganic carbon and dissolved organic carbon, respiration of carbon dioxide), and carbon flux estimates from fish biomass (i.e., bioenergetics, size-based allometric relationships, stable isotopes). Planned products resulting from this workshop and ongoing working group efforts include two peer-reviewed manuscripts focused on the synthesis of fish carbon flux research and a quantitative analysis of fish carbon flux. Learn more about the working group and view presentations from this workshop on the project’s web page. A full workshop report will be available in the next few months.
