Table 1. Projected number of fish, by size group, needed to evaluate the
relation between survival of razorback sucker by size at release into the
Gunnison and Colorado rivers, FY-96 through FY-2000. Priority will be given
to stocking the Gunnison River if sufficient numbers of fish are not available
to stock both rivers.

Number of fish may have to be adjusted depending upon the number of fish
produced from paired matings, survival to stocking, and available space
b Additional propagation facilities will be available by FY-98 for increased
production of captive-reared razorback suckers.
