Work Element Usage Report
Title:
D: 190 - Remove and Relocate Fish Predators from Acoustic Telemetry Array
Description:
Prior to conducting the age-0 gear encounter rate experiment (WE G), CTCR biologists and technicians will capture and remove or relocate potential age- Sturgeon predators. Predators will be captured using gill nets and cod traps fished within and around the outside of the telemetry array over a 2 week period prior to releasing the acoustic tagged fish. We will fish 80 overnight sets with 200' experimental gill nets and 80 overnight sets with cod traps. All non-native predators (e.g., Walleye and Bass) will be euthanized and discreetly discarded (sunk) in the reservoir. All native predators (e.g., Burbot) will be trans-located outside of the study area or held in a net pen within the reservoir until the experiment has been completed.
WE Agreement Type:
Contracted
Deliverable Specification:
CTCR Biologists and technicians will remove and euthanize all non-native predators (i.e., Walleye and Bass) and translocate all native predators (i.e., Burbot) from the age-0 White Sturgeon telemetry study area two weeks prior to the age-0 Sturgeon release. The target number of predators to be removed, based on previous survey data, is ~250 Walleye >300 mm FL, ~150 Burbot >300 mm TL, and ~15 Smallmouth Bass >200 mm FL.
