APPENDIX C 

 RESEARCH PROBLEMS IDENTIFIED BY BAY SCIENTISTS 



1. Relate commercial harvest of menhaden to that of other species. 



2. What is the sustainable yield for Bay fisheries, and where should it be cropped? 



3. More information is needed about fish food species, Atlantic menhaden, anchovies, penaeid 

 shrimp, mysids. 



4. What eats hogchokers? 



5. What are the food web pathways for phytoplankton production if zooplankton only consume 

 10% of daily net production? 



6. What is the Bay nutrient budget, including benthic regeneration? 



7. How are changes in nutrient inputs and primary productivity transferred up the food chain? 



8. What are food chain consequence of species changes in phytoplankton? 



9. What will happen to the ecosystem if nutrient loading is (is not) cleaned up? 



10. What is the N vs. P limitation for primary production— seasonal and spatial variations? 



1 1. What are the effects of land-use policies on the Bay? 



12. What are the nutrient uptake kinetics in the estuary, or how can productivity be kept down? 



13. What is the abundance and distribution of benthic organisms and plankton? 



14. Better fisheries monitoring data is needed, both of commercial and recreational catch. 



15. What are the synergistic effects of pollutants? 



16. Large-scale regional studies are needed rather than very localized studies in the Bay. 



1 7. What is the impact of agricultural pesticides and herbicides? 



18. Generally more quantitative work is needed. 



19. What are the impacts of PCBs, toxins?
