Reflecting on each year’s achievements provides valuable insights for growth and sparks inspiration for the year ahead. Here is a rundown of our numbers from the past year.
In California:
1 fish sorter prototype fabricated and shipped to Finland.
6 Rotary screw traps operated in 3 watersheds.
7 sturgeon captured in the San Joaquin River fyke traps.
9 PIT tag antennas including 4 solar-powered systems installed in Santa Clara County.
9 HOBO data loggers in operation, monitoring temperature and water level in Big Chico Creek.
19 sites across 7 streams assessed as part of the Surface Water Ambient Monitoring Program (SWAMP), which included the collection of 28 benthic macroinvertebrate samples.
23 tagged rainbow trout/steelhead (Oncorhynchus mykiss) recaptured on the Calaveras River.
23 different fish species captured in rotary screw traps.
37 miles of steelhead habitat surveys completed in the Salinas River Basin.
40 locations sampled for tidewater goby in the Salinas Lagoon and nearby watersheds.
40 threatened green sturgeon captured and tagged in the Sacramento River.
100+ eDNA samples collected.
164 predator diet samples analyzed in the San Joaquin rivers.
165 bird species counted digitally and in person at 3 central valley orchards.
688 fish captured and 567 bass, catfish, and pikeminnow PIT tagged for the South San Joaquin Delta Predator Monitoring Study.
1,317 rainbow trout/steelhead (Oncorhynchus mykiss) captured via hook-and-line sampling on the Calaveras and Stanislaus rivers.
2,129 Chinook salmon observed passing through the Tuolumne River weir.
2,884 fish PIT tagged on the San Joaquin, Stanislaus and Calaveras rivers.
3,486 Chinook salmon observed passing through the Stanislaus River weir.
13,006 rainbow trout observed during snorkel surveys of the Stanislaus, Tuolumne, and Calaveras rivers.
17,000 cubic yards of dredged Sacramento River material monitored for fish entrainment in the Sacramento and Stockton Deep Water Ship channels.
18,936 fish captured in the rotary screw traps on the Tuolumne and Calaveras rivers.
In the Mekong Basin:
1 community fisheries co-management system established in Dondeng Village in the Xe Champhone wetlands including:
- 2 no-take fish conservation zone (FCZs)
- 1 sport fishing area
- 1 community fishing license area
5 new FCZs established in the Xe Champhone wetlands.
12 target endemic species surveyed in the Nam Ngiep 1 watershed, with 5 of the 12 species found across five sites.
13 oxbows in the Xe Champhone wetlands surveyed.
34 villages visited during project implementation.
35 individuals trained in FCZ and community fisheries co-management.
195 eDNA samples collected from the Mekong, Irrawaddy, and Salween river basins across 4 countries: Cambodia, Laos, Thailand, and Myanmar.
3,567 fish sampled (34 species from 13 families were identified) in the Xe Champhone wetlands.
Other Notable Accomplishments:

Thank you to our clients, project partners, and staff for the hard work and dedication to fisheries research. We look forward to what 2025 brings!
