A 16‐Year Green Sturgeon Population Survey: Investigating River Discharge, Species Identification, Sampling Technology, Survey Extent and Possible Spawning Cyclic Dominance

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Monitoring and understanding the population structure of anadromous fishes is vital to their conservation. The southern distinct population segment of green sturgeon (Acipenser medirostris) is a threatened long‐lived anadromous fish, for which we have insufficient information about fundamental aspects of population structure.
