A machine learning tool for design of behavioral fish barriers in the Sacramento-San Joaquin River Delta

Executive SummarySurvival of out-migrating juvenile salmonids (Oncorhynchus spp.) through the Sacramento-San Joaquin River Delta averages less than 33 percent, depending on water flow through the delta, and is partially governed by the distribution of fish among three Sacramento River distributaries: Sutter, Steamboat, and Georgiana sloughs. Behavioral altering structures in the junctions of the d

Bringing partners together: A symposium on native lampreys and the Pacific Lamprey Conservation Initiative

A symposium at the 2022 American Fisheries Society meeting highlighted collaborations among biologists, policymakers, and Native American tribes addressing conservation for native lampreys. We present key findings from the symposium and related research and an example of grassroots effort to protect and restore Pacific Lamprey.

Shoreline slope influences movements of larval lampreys over dewatered substrate

Larval lampreys are filter feeders that live for several years burrowed in fine sediments in freshwater streams. Stream side channels and edges, where larval lampreys gather, are vulnerable to natural and human-caused dewatering. Water level reductions can strand and kill thousands of larval lampreys, in part because many remain burrowed until their habitats are exposed, at which point larvae must

Development and Refinement of Methods for Early Detection of European Green Crab

European green crabs are one of the most widespread marine invasive species on the planet. Where they are abundant, green crabs compete with other crabs and disturb sediment which can lead to loss of eelgrass and associated habitat essential for commercial, cultural, and ecologically important fish and invertebrate species. Green crab also are a major predator of clams, mussels, and oysters.
