Conservation aquaculture

olympia oyster

Check this new article about conservation aquaculture of native oysters. Also, here is a press release from UCSB and a two-page summary of the results.


“The study published in Plos One, recommends locations and methods for the strategic expansion of conservation aquaculture to bring back Olympia oyster populations…”


“Our collaborative process engaging diverse stakeholders including managers, scientists, Indigenous Tribal representatives, and shellfish growers can be used elsewhere to seek win-win opportunities to expand conservation aquaculture where benefits are maximized for both people and imperiled species.”


“They developed a clear framework for decision making that considered conservation goals and human needs together. The project includes recommendations to strategically use conservation aquaculture where the rewards outweigh the risks.”

WSN Ciencias Marinas special issue

Check out the newest issue of Ciencias Marinas. It has 10 scientific articles that were presented at the 2019 Western Society of Naturalist meeting that was held in Ensenada, Mexico. Also check the editorials about the past, present, and future of international research in northwest Mexico and the history of WSN international meetings.


Predicting changes in structure and function of ecosystems requires large-scale and long-term studies. We integrated kelp forest data from 469 sites/373 species spanning Alaska, USA, to Baja California, Mexico.

Results from a recent publication suggest that coastal communities that are dependent on kelp forests will be more impacted in the southern portion of the California Current region, highlighting the urgency of implementing adaptive strategies to sustain livelihoods and ensure food security.

Collective Action in Northwest Mexico Fisheries

Some sustainable fisheries in northwest Mexico have been collectively developed and implemented by fishers, NGOs, academia, and government. This allows the users to be involved in the decision making, using the best available science, and regulations to be appropriate. This management strategies might make this socioecological systems more resilient to climate change.

California’s Other Gold

Researchers assess how the quality of red sea urchin roe — uni — influences fishermen’s behavior

They explored how sea urchin quality could be quantified and used to predict fishermen’s behavior. She and her colleagues found that understanding the local dynamics of this fished resource can make management strategy evaluation and planning more effective. The findings appear in the journal PLoS ONE.

Tijuana River Valley Historical Ecology Investigation

The Tijuana River Valley Historical Investigation Report is out. It highlights the changes the Tijuana River Valley has gone trough since the mid 1800s. It presents a historical perspective on how the valleys ecosystems used to function, which will help managers steer restoration and management efforts.
