Evaluating energy flows through jellyfish and gulf menhaden (Brevoortia patronus) and the effects of fishing on the northern Gulf of Mexico ecosystem

Creator:: Robinson, Kelly L., Ruzicka, James J., Hernandez, Frank J., Graham, William M., Decker, Mary Beth, Brodeur, Richard D., and Sutor, Malinda
Abstract:: Fishery management production models tend to stress only the elements directly linked to fish (i.e. fish, fish food, and fish predators). Large coastal jellyfish are major consumers of plankton in heavily fished ecosystems; yet, they are frequently not included as model components. We explore the relationship between gulf menhaden (Brevoortia...

Jellyfish, Forage Fish, and the World’s Major Fisheries

Creator:: Robinson, Kelly L., Ruzicka, James J., Decker, Mary Beth, Brodeur, Richard D., Hernandez, Frank J., Quiñones, Javier, Acha, E. Marcelo, Uye, Shin-ichi, Mianzan, Hermes, and Graham, William M.
Abstract:: A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap...

Abstract:: This report reviews the state of the California Current System (CCS) between winter 2012 and spring 2013, and includes observations from Washington State to Baja California. During 2012, large-scale climate modes indicated the CCS remained in a cool, productive phase present since 2007. The upwelling season was delayed north of...

State of the California Current 2011–2012: Ecosystems Respond To Local Forcing as La Nina Wavers and Wanes

Abstract:: The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:: Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.
Abstract:: The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Columbia River plume fronts. II. Distribution, abundance, and feeding ecology of juvenile salmon

Creator:: De Robertis, Alex, Morgan, Cheryl A., Schabetsberger, Robert A., Zabel, Richard W., Brodeur, Richard D., Emmett, Robert L., Knight, Carolyn M., Krutzikowsky, Gregory K., and Casillas, Edmundo
Abstract:: Well-defined fronts develop at the seaward edge of riverine plumes where suspended materials and planktonic organisms are concentrated by convergent water flows. Riverine plume fronts have been hypothesized to be favorable fish habitats because they can lead to localized prey aggregations. We examined the spatial distribution of juvenile Pacific salmonids...
