Welcome to the Chapple Big Fish Lab
In the Chapple Big Fish Lab, we study sharks and other large marine predators around the world focusing on their movements, behaviors and population dynamics. From South Africa to Australia to California, using state-of-the-art technology and techniques, we sample and electronically tag animals to gain insights into their lives when we aren’t there to observe them. In Oregon, we leverage partnerships with industry, management, science and local communities to study the sharks off our coasts to better understand the roles these animals play in our marine ecosystems and economies. Relatively little is known about how sharks affect our coastal ecosystems and communities in the Pacific Northwest, but here in the Chapple Big Fish Lab, we are changing that.
Did you know?
The Pacific Northwest is home to at least 15 species of sharks?! They range in size from the Brown Catshark (~2.2 ft or 65cm) to the Basking shark (>30 ft or 10m), with lots of sharks in between. To learn more about the sharks of the PNW visit our Sharks of Oregon page and explore the different species off our coast.
Shark Sighting in Oregon or Washington?
Tell us all about it on our Shark Sighting page to help us better understand when and where sharks are along the PNW coasts.
Chapple Big Fish Lab DEI Statement
In the Chapple Big Fish Lab we acknowledge there are systemic barriers and inequality in STEM fields- especially in shark science- and are committed to increasing representation of historically underrepresented groups in science. We are committed to inclusivity and strive to make access to research, opportunity and experience more equitable. We value diverse thought, experience, preferences and skills and feel we are stronger and more powerful as an inclusive community. We also acknowledge that we still do not fully understand the impact of historic and systematic inequality and as a lab we continue to actively evolve and work to fully represent the diversity of the broader global community.
As a largely field-based lab, we appreciate that field work can be intimidating and unwelcoming and we strive to create safe and accessible work space for all. We also participate in the FieldSafe program at OSU, to ensure that field work is safe to people of all identities.
Our Specific Actions
- We acknowledge the diverse cultural context of our work and integrate various types of knowledge and value in our interpretations and presentations
- We strive to offer opportunities to recruit and mentor students from diverse backgrounds and experiences.
- We use science communication to make science and research more accessible to people of all abilities Learn more about our ORSEA and OCEANTRACKS curriculum.

Vouchers are now on sale for a new specialty Oregon license plate that researchers hope will inspire people to think differently about the sharks living just off the Oregon Coast.

Using a monitoring gadget akin to a FitBit, paired with a camera, researchers gathered data that gave them a rare chance to understand how collisions with vessels affect massive sea creatures. These accidents are becoming a bigger issue...

“It’s more often than not a shark is going to see you than you are going to see the shark. I’m sure this fisherman has had a shark around them before,” said Oregon State University professor Taylor Chapple.

Taylor Chapple, an assistant professor at Oregon State University and white shark expert, explains how the diet of these animals – which probably comprises tuna and small fish – is also very different from that of other white sharks around the...

Tag and catch data suggest that salmon sharks exhibit "sexual segregation" in the Pacific, with females dominating the Northeast (up near Alaska) and males in the Northwest (Japan, Russia, Bering Sea)

Sharks can detect electrical fields through the use of the Ampullae of Lorenzini, sense organs that form tube like structures under the skin.

Before vitamin A was synthesized in a lab Soupfin sharks were harvested for their livers naturally rich in vitamin A. This fishery was highly exploitative and led to the collapse of the Northeast Pacific population.
