Reproductive strategies and rockfish: A life history traits framework for fisheries management

Any trip to an aquarium or seafood market reveals the incredible variety of fishes. These fishes not only differ in how they look, but in traits related to life history. Life history traits include maximum body size, longevity, age at maturity, and fecundity – the number of eggs produced. Fishes that have the same phylogeny, or evolutionary history, share similar traits. Conversely, unrelated fishes occasionally evolve similar traits independently.

Colleen Petrik wins PICES 2016 Science Board Best Presentation Award

Nereus Fellow at Princeton University Colleen Petrik won the Science Board Best Presentation Award at the North Pacific Marine Science Organization (PICES) annual meeting, held in San Diego, from November 2 to 11. She gave a plenary presentation on “The response of fisheries production to natural and anthropogenic forcing: past, present and future”, using the results of the model she developed with her Nereus research.

25 Years of PICES: Celebrating the Past, Imaging the Future annual meeting

From November 2 to 13, the North Pacific Marine Science Organization (PICES) held their annual meeting in San Diego, USA. The meeting celebrated the 25th anniversary of PICES with the theme of looking at the past 25 years and imagining the next 25. Some of the topics of interest included coastal ecosystem stressors, loss or changes of marine biodiversity, changing productivity and species distributions in response to climate change, developing outlooks or forecasts of future ocean ecosystems, and examining climate change impacts on ocean ecosystems and human society.

PICES Annual Meeting

Nereus Fellow at Princeton Colleen Petrik will be giving a plenary talk entitled “The Response of Fisheries Production to Natural and Anthropogenic Forcing: Past, Present and Future” at the PICES Annual Meeting in San Diego. The talk presents a mechanistic model to represent immature and mature stages of forage fishes, large pelagic fishes, and large demersal fishes, as well as preliminary of fish biomass under (1) pristine non-anthropogenic historical forcing (no anthropogenic CO2, no fishing), (2) historical climate without fishing, (3) historical climate with fishing, (4) and projected business-as-usual climate and fishing.

Nereus Program researchers will be attending the Ocean Sciences Meeting 2016, in New Orleans, Louisiana. The theme for the 2016 meeting is: Ocean Sciences at the Interface. The 2016 Ocean…

Collaboration with Stockholm Resilience Centre on global fish biomass distribution model

Colleen Petrik, Senior Nereus Fellow at Princeton, visited the Stockholm Resilience Centre at the University of Stockholm from October 26 to 30 to collaborate with former Nereus Fellow James Watson. While with the Nereus Program, Watson developed a simulation model of global fish biomass distribution. This model demonstrated that the ability of fish to swim towards high food and growth environments had a drastic effect on the spatial distribution of fish biomass, especially that of top predators.
