Marine Species Monitoring

Occurrence of Green Sturgeon in Inland Waters (historical tag analysis)

Introduction & Objectives

The southern distinct population segment (DPS) of the green sturgeon is listed as threatened under the Endangered Species Act.  The green sturgeon’s occurrence and habitat use is not well known.  Therefore it is currently unknown if the green sturgeon occurs and uses areas where the Navy conducts training and testing activities.  Over the past 15 years, hundreds of green sturgeon have been tagged with acoustic pinger tags which may have been detected by receivers deployed in the Puget Sound area.  The objectives of this project are to compile and review existing databases of green sturgeon acoustic tag detections in Puget Sound and the Straits of Juan de Fuca, analyze the data for distribution and seasonality of distribution, and identify any key physical nearshore habitat and water quality conditions that might explain the distribution. 

Technical Approach

Data will be compiled from green sturgeon acoustic tag deployments and acoustic receiver deployments from west coast databases and scientists. 

Progress & Results
