Swordfish Research 

PIER researchers have several studies focused on swordfish ranging from gear development trials and tagging to physiological studies on swimming performance.  

Video describing the gear development work that is ongoing at PIER.  

The team is now working with cooperative fishers to trial deep-set buoy gear (DSBG) as well as Linked Buoy Gear in the Southern California bight.  The gear types were designed by the PIER team in cooperation with NOAA and supporting partners. The deep-set techniques are designed to selectively target swordfish at depth during the day and simultaneously avoid sensitive bycatch species like sea turtles and marine mammals.  

DSBG is now in exempted status with five vessels permitted to perform the trials through the 2017 swordfish season.  This work continues to partner with the NOAA South Coast Region, the NOAA Bycatch Reduction and Engineering Program, the Pew Foundation and The Nature Conservancy.  

Tagging Research

PIER researchers have recently been awarded federal funding from the NOAA Saltonstall-Kennedy Program to investigate swordfish stock structure in the Eastern North Pacific. The study couples electronic tagging with recent genetic advancements to piece together annual migration patterns, identify spawning areas and differentiate stock structure.  The work is being performed in collaboration with the Alvarado-Bremer Laboratory at Texas A&M as well as colleagues from CICESE in Ensenada, Baja California.

White Seabass Stock Assessment


PIER researchers team up the Center for the Advancement of Population Assessment Methodology (CAPAM) and the California Department of Fish and Wildlife to produce the first, formal stock assessment for the white seabass.  The work was headed up by Dr. Juan Valero and SIO doctoral student Lynn Waterhouse. The full assessment as well as summary information can now be found online.  Read more about this.
