Re-routing irrigation water away from a reclaimed pond was another NNFC <br />technique used to prevent re-invasion by inlet water laden with larval fish (this pond has <br />spring water as an alternate water source). Unfortunately, nonnative fish were sampled <br />in this pond post-reclamation. The presence of fish either resulted from failure of the <br />reclamation to kill all fish and/or re-invasion from neighboring ponds. <br />f;.li • ? '? J tjY4 <br /> <br />Figure 23. Black plastic was used as an alternative to chemical reclamations. It was <br />spread over the surface of a 0.5 surface acre pond to remove a stunted green sunfish <br />population and excessive filamentous algae. <br />Information and Education <br />Both the Recovery Program and the CDOW recognized the need to disseminate <br />information concerning nonnative fish control due to several misconceptions and <br />concerns held by various publics regarding: 1) the use of fish toxicants and their impact <br />on non-target wildlife; 2) the perceived loss of fishing opportunity; 3) the source of <br />revenue used in the NNFC effort; 4) the feared loss of landowner rights if endangered <br />fish were collected in privately owned ponds; 5) the alleged value of sport fish over that <br />of native fish; and 6) the impact of the recently adopted CDOW west slope nonnative <br />fish stocking regulation on private fish vendors (CDOW et al. 1996). The Recovery <br />Program and CDOW provided funding for the following information and education <br />efforts to address these concerns. <br /> <br />42
