This <br />debate centered around the ISMP's capacity to accurately sample centrarchid relative abundance in riverine <br />habitats, and to provide a reliable index for monitoring changes in centrarchid abundance as part of <br />evaluating the effectiveness of the then proposed Procedum The P-rQgg m , since finalized and adopted in <br />October/November of 1996 (CDOW et al. 1996), are intended to ensure that all future stocking of nonnative <br />fishes in the UCRB is consistent with the recovery of endangered fishes. <br />The Procedures themselves specify that concurrent with implementing their provisions, "the <br />Recovery Program will conduct a peer-review study to evaluate the effectiveness of the ISMP to detect <br />changes in the survivability and/or abundance of routinely stocked fish" (Appendix A, p. 5). This discussion <br />about the detectability of centrairchids in riverine habitats of the UCRB using the ISMP centers around the <br />late summer seine protocol in backwater habitats where centrarchids have been shown to be most prevalent in <br />collections (McAda et al. 1994, 1995). The Procedures provide for the stocking of largemouth bass <br />Micropterus salmoides, bluegill Lepomis macrochirus, and black crappie Pomoxis nigromaculatus into <br />2
