Solo human casts fishing line into sea from a rocky cliff

Can a little bit of a good thing be worse than nothing at all?

The world’s oceans are increasingly managed as Marine Protected Areas (MPAs) where human activities are carefully regulated to support ocean health. But the amount of protection in a marine protected area varies widely. A recent study begs the question — is partial protection actually worse than no protection at all? Ellie OldachHello! I’m a third-year […]

Sea-farming our way to a better future

The rise of aquaculture promises to support coastal economies. But in a recent paper, authors argue that the economy is only part of the question— community well-being is just as important. If done right, aquaculture has the potential to grow not just economies, but strong communities, too. Ellie OldachHello! I’m a third-year PhD student at […]

How to Plan a Marine Protected Area

The start of a new decade offers a chance to reflect on the past. We’ve missed our target conservation goals for global marine protected areas (MPAs), but maybe — just maybe — we’ve learned some important lessons about ocean governance along the way. In a recent paper, authors trace the history of MPA development in […]

Seafood market with distancing

No Time to Waste for U.S. Seafood

Impacts of COVID-19 are rippling through U.S. seafood systems. Understanding those impacts is critical for directing aid. But typical research can lag years behind a crisis, and conclusions can come too late to help. Recognizing the need for speed, a team of seafood researchers took a creative approach to track COVID-19 impacts in (almost) real-time… […]

Fisheries and COVID-19: It’s stormy out there

As the pandemic continues to ripple across communities, the commercial fishing industry faces a number of particular challenges. There’s a lot we still don’t know, but it’s already clear that navigating COVID-19 will be no simple feat. Ellie OldachHello! I’m a third-year PhD student at University of California, Davis, in the Center for Environmental Policy […]

Surf’s up! Drones are, too

Australia’s coast is a beloved spot for surfing and swimming. It’s also home to sharks, and these ocean activities can bring people into unwanted contact with the toothy ocean giants. Drone surveillance offers a shark-friendly way to keep swimmers safe. But does this strategy have the public support it needs to get off the ground? […]

Who do you talk to about marine biosecurity, mate? Social networks matter in managing Australia’s ocean pests

Scientists in Australia recently mapped the nation’s biosecurity community as a social network, revealing key characteristics that help and hinder marine pest control. Ellie OldachHello! I’m a third-year PhD student at University of California, Davis, in the Center for Environmental Policy and Behavior. My research focuses on how coastal communities make decisions around climate change […]

Be careful what you fish for: Using protected areas to save lobster claw size

Fishing doesn’t just remove fish from the sea– it can also change the evolutionary trajectory of a species. For lobster, fishing pressure is driving populations to have smaller and smaller claws. Could marine protected areas (MPAs) rescue the large-clawed trait of the lobsters we love? Ellie OldachHello! I’m a third-year PhD student at University of […]

How do you share an octillion? Ensuring equitable access to the ocean genome

There are 3 octillion species in the ocean. The staggering amount of genetic material these species contain could offer answers to some of society’s great challenges, holding keys to curing cancer or reducing greenhouse gas emissions. The problem? Countries with less access to the financial and technical investment needed to explore this material are left […]

Map with shipping corridors

How do we navigate a climate-changed sea? By getting Inuit perspectives on the map.

Climate change is impacting the waters of Arctic Canada. As ice cover declines, interest in using these routes for international trade and shipping is increasing. However, increasing ship traffic has real implications for the health of the people and wildlife of this area. Inuit communities took part in the Canadian government’s planning process to ensure […]

    Have you ever seen a lobster molt? Because lobsters have exoskeletons, every time they grow they have to climb out of their old shell, leaving them soft and vulnerable for a few days until their new shell hardens. Young, small
