Fisheries Biologist

Chrissy Sonke is a fisheries biologist with 15 years of research, project management, and database management experience in inland fisheries. Chrissy regularly develops and manages databases for complex projects that require extensive coordination with federal, state, and local governments; consultants; landowners; and recreational groups. She also has experience in obtaining a variety of regulatory permits, expertise in GIS data management, and experience in web and graphic design.

Chrissy has constructed multiple bilingual Access databases to support fisheries work in the Mekong Basin and has coordinated Lao staff to follow data quality assurance/quality control procedures. She has also worked with remote sensing data from projects using Vaki Riverwatcher fish counters and PIT tag antennas, and has co-authored associated technical reports. Chrissy is experienced with several methods commonly used to monitor fish populations, including rotary screw trapping, electrofishing, seining, gill netting, acoustic tracking, and SCUBA surveys.
