Nereus Alumna and Assistant Professor at East Carolina University Rebecca Asch has been invited to speak at at Horn Point Laboratory (HPL), a part of the University of Maryland’s Center for Environmental Science.
Nereus Fellow Rebecca Asch will be attending this symposium, which has the goal of revitalizing nternational cooperation on investigations of small pelagic fishes, and developing a framework to address unresolved questions, such as the impact of climate and fishing pressure on the resilience of small pelagic populations.
Variations in climate lead to fluctuations and changes in fish stocks; they can have effects on such things as fish behaviour, distributions and growth. Because of this, fisheries management has to respond dynamically to these fluctuations. If management decisions are made primarily on past patterns, the negative impacts can be exacerbated, especially with climate change.
Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an ocean area may seem like a good predictor for the amount of fish that can be caught there, but a new study by Nereus Program researchers finds that this relationship is not so straightforward
According to the FAO, anchovy and sardine made up 13% of global catch in 2012. These small fish are consumed by humans, marine mammals, seabirds, squid, and other fish. They are also used for aquaculture feed, industrial oil, and health supplements. “Climate, Anchovy, and Sardine” a new study in the Annual Review of Marine Science, co-authored by Nereus Alumni Rebecca Asch (Princeton University) and Ryan Rykaczewski (University of South Carolina), reviews the past, present, and future of anchovy and sardine.
In spring, as the plant buds push up through the ground and the days get warmer and longer, the baby salmon fry hatch out of their eggs and start swimming and feeding. At this time, their food – phytoplankton – should also bloom. But due to climate change-induced warming, the fry of many fishes, such as salmon, are coming out earlier or later, as are the phytoplankton blooms, which can cause a mismatch between when the food is available and when the fry need it.

The Ocean Carbon and Biogeochemistry (OCB) Summer Workshop is an annual event where scientists leading research on the carbon cycle and circulation of nutrients in the ocean meet to discuss advances in their field and jointly plan new research initiatives. This year it was held from July 25 to 28 at the Woods Hole Oceanographic Institution in Massachusetts, USA.

“Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods,” co-authored by Nereus Fellow Rebecca Asch (Princeton University), was recently published in Elementa: Science of the Anthropocene. The paper looks at when and how long phytoplankton blooms occur in the North Atlantic. The authors found a correlation between spring bloom start days and the duration of the bloom, with early blooms lasting longer.
