<br />a Abundance estimate was not calculated due to lack of depletion attributed to increased sampling
<br />efficiency during removal sampling. The survival estimates are based on the total number of razorback
<br />suckers captured.
<br />Bonytail Survival and Growth
<br />Larval bonytail escaped from the two enclosures into the surrounding wetland and
<br />other enclosures due to water overtopping of the enclosures during unexpected high water
<br />in 2003. However, upon sampling the enclosures, survival of bonytail was confirmed.
<br />Ten bonytail were captured in eight of the twelve enclosures during evaluation sampling.
