Demand
12. Standardize key terminology and processes (e.g., cost of producing various sizes and
species of fish, data about the existing aquatic habitat base, angler use, etc.) to minimize
confusion about key data and how they were derived and used.
13. Undertake an economics-based study that examines the cost, benefits, and anglers'
willingness to pay for hatchery-reared fish in Colorado. This should also incorporate results
to enable an understanding of "angler satisfaction" and the estimation of angler success and
demand by category. The study should be done on a broad scale so that the results can be
applied to the entire hatchery system.
14. Implement user pay mechanisms to determine the demand for catchable trout and to enable
DOW to index hatchery production.
Hatcheries
15. Initiate research to determine if UV light, sand filtration, or other screening materials
provide a viable methodology for eliminating WD spores from hatchery supply waters.
16. Eliminate all production of WD+ trout from state hatcheries and accept the associated loss
of stocking and recreation days.
17. Reduce or eliminate the WD pathogen from existing state production facilities.
18. Buy or lease WD- trout hatcheries.
19. Buy WD- trout from the private sector.
20. Modify existing WD- state hatcheries to produce more fish.
21. Trade for WD- trout from federal hatcheries.
22. Produce only fry and fingerling trout at WD- state hatcheries.
