Jose Marin JarrinView profile
Associate Professor
Jose Marin Jarrin is an Associate Professor in the Department of Fisheries Biology at Cal Poly Humboldt's College of Natural Resources. Originally from Ecuador, he holds a B.Sc. in Biology from the University of Guayaquil (2002), an M.Sc. in Marine Biology from the Oregon Institute of Marine Biology (2007), and a Ph.D. in Fisheries Science from Oregon State University (2012). Before joining Cal Poly Humboldt, he served as a Senior Fisheries Ecologist at the Charles Darwin Foundation (2016-2018), a Prometeo Research Fellow at Escuela Superior Politecnica del Litoral in Ecuador (2015-2016), and completed postdoctoral research at Central Michigan University (2013-2015). Dr. Marin Jarrin's research focuses on high-use and data-limited fisheries species, with particular emphasis on providing vital early and adult life history data for fishes and crustaceans. His work examines impacts from local fishery pressures and climate change, primarily through the lens of tropical Eastern Pacific ecosystems, especially the Galapagos Islands, and temperate systems along the California coast. He leads the Marine Fisheries Ecology Lab and has developed innovative approaches to studying sandy beach surf zones as critical habitats for juvenile fish species. His research spans multiple methodologies including otolith analysis, population dynamics, trophic ecology, and collaborative fisheries management approaches. Analysis of Dr. Marin Jarrin's recent publications reveals a strong focus on Galapagos Island fisheries, with significant attention to species life history parameters, impacts of climate variability, and marine protected area effectiveness. His work bridges temperate and tropical systems, connecting research in Northern California with Ecuadorian and Galapagos waters. A notable trend is the increasing emphasis on community-based and collaborative research approaches, particularly with tribal communities along the North Coast of California and artisanal fishers in Ecuador. His publications demonstrate expertise in both field ecology and advanced analytical techniques for fisheries assessment. Dr. Marin Jarrin actively mentors graduate students, with several recent theses focusing on surf zone ecology, fisheries management, and species life history. His teaching portfolio includes courses in Ichthyology, Fisheries Science Communication, US and World Fisheries, Advanced Ichthyology (with specialization in Sharks and Rays), Marine Fish Ecology, and Techniques in Fisheries Biology. His research program has secured funding for projects including the Sandy Beach Surf Zone MPA project and the Northern California Tribal Fisheries Collaborative, demonstrating his commitment to applied fisheries science that directly informs management decisions.
