The study used traditional hook and line techniques to deploy over 100 archival tags off the coast of Baja California Sur, Mexico. The study revealed relatively high short-term recapture rates, and documented depth trends for this poorly studied species. The work was performed in collaboration with Dr. Sofia Ortega from CICIMAR in La Paz. Read more about PIER wahoo research. Collaborative studies with researchers from Scripps Institution of Oceanography have also focused on the respiratory physiology of the wahoo. These...
Rooster Fish
[vc_row][vc_column][mkd_section_title title="PIER has several projects focused on the movements, post-release survivorship and general biology of roosterfish.

The findings from this work suggest that roosterfish are resilient and that they can, when handled properly, survive the acute effects of capture and release. The work has also revealed that roosterfish have relatively large home ranges with fish routinely moving over 30 kilometers per day. Additional studies on growth and reproduction are being conducted in conjunction with the...
Thresher Sharks

Off California, the bigeye and common thresher sharks are typically the most prevalent, but in some years we can also find pelagic threshers here as well. Below you can find areas in PIER has worked on this group of pelagic sharks and links to additional pages that describe the studies in more detail.

White Seabass

Over the past 100 years of exploitation, it has become apparent that white seabass are highly susceptible to overfishing, with stocks plummeting on at least three different occasions. This susceptibility is likely due to a combination...
Swordfish

Collaborative researchers: Diego Bernal, Ph.D. (University of Mass., Dartmouth) Ashley Stoer, doctoral candidate (UMD) Jeanine Sepulveda, PhD (MiraCosta College) Doug Syme, PhD (University of Calgary) PIER researchers are collaboratively working with several laboratories to investigate several aspects of swordfish physiology. Given the PIER teams access to live swordfish, ongoing studies range from examining heat balance and vascular specialization to the effects of temperature on muscle performance. Thermal Studies This work uses a...
