Lyall is a Senior Fisheries Scientist with the California Oceans Program at The Nature Conservancy, and is based in San Diego at Scripps Institution of Oceanography. Lyall is an avid fisherman, diver, and outdoorsman whose passion for understanding ocean ecosystems led him to a lifelong career in marine science. Lyall’s research is founded in science-industry-agency collaborations with a specific focus on the application of fisheries management models to improve long-term health of ocean ecosystems,fisheries, and fishing communities, particularly in the context of extreme environmental events as a function of climate change.
Prior to working for the Conservancy, Lyall completed a B.S. in Aquatic Biology at the University of California Santa Barbara, M.S. in Marine Biology at CSU Long Beach, Ph.D. in Marine Biology at Scripps Institution of Oceanography, and a National Research Council Postdoctoral Fellowship at the NOAA Southwest Fisheries Science Center in La Jolla, California.

What Lyall is working on now:
Currently, Lyall is leading projects focused on 1) Fishery Disasters in the U.S., 2) climate change impacts to west coast fisheries from Mexico to Alaska, 3) experimentation as a toolfor adaptive fisheries management, 4) management solutionsto minimize whale entanglementsand bycatchin Pacific fisheries, and 5) novel tools and approaches to improve nature and people outcomes in data limited fisheries.

The health of ocean ecosystems is critical to maintaining natural biodiversity and sustainable fisheries, but federally-declared fishery disasters are reflecting devastating impacts to ecosystems, economies, and communities. This study represents the first nationwide synthesis of fishery disasters during the 30-year history of the federal assistance…

Due to decades of heavy fishing pressure and steep population declines worldwide, the conservation status of the soupfin shark was elevated to Critically Endangered globally in 2020 by the IUCN. This species is commercially fished in the United States, but the fishery has not undergone a…

In response to anomalously warm sea-surface temperatures, poleward shifts in the geographic range of hundreds of marine organisms worldwide have been documented. This paper reports on the unusual occurrences of 36 fish species recorded from the Southern California Current System (SCCS) during the period of…

In 2006, The Nature Conservancy of California purchased 13 federal groundfish permits in California with the objective of managing the fishing and reporting activities in a manner that protected sensitive habitats and species. At that time, collecting data for this fishery was done with paper…

Among abalone species that were once harvested along the California coastline, red abalone (Haliotis rufescens) supports the remaining recreational fishery. To support development of a red abalone fishery management plan, non‐governmental organizations have initiated expanded data collection and developed fishery management strategies. In this paper,…

This paper presents how voluntary collective agreements amongst fishermen can be used to reduce risk of bycatch of sensitive species and improve fishery performance in the West Coast groundfish fishery. We describe the challenges and results of designing and implementing an “insurance risk pool” to…
