Capturing and Tagging Wild Age‐0 and Age‐1 Paddlefish in a Great Plains Reservoir

Over the period 2–15 August 1996, age‐0 and age‐1 paddlefish Polyodon spathula were captured with long‐handled dip nets in Lake Sakakawea, a Missouri River mainstem reservoir in North Dakota. Catch rates varied from about 20 fish/boat‐hour (a boat‐hour is defined as a 1 ‐h effort by a boat driver an...

Description
Summary:Over the period 2–15 August 1996, age‐0 and age‐1 paddlefish Polyodon spathula were captured with long‐handled dip nets in Lake Sakakawea, a Missouri River mainstem reservoir in North Dakota. Catch rates varied from about 20 fish/boat‐hour (a boat‐hour is defined as a 1 ‐h effort by a boat driver and two netters) at the beginning and end of the sampling period to 50 fish/boat‐hour during the middle of the sampling period. Previously untagged age‐0 fish (2,346) were marked with binary coded wire tags implanted in their rostrums. This capture and tagging procedure has promise in Lake Sakakawea and elsewhere as a stock assessment tool for wild paddlefish.
