If studies indicate remnant populations are too small or isolated to respond to habitat modifications then explore additional management options, including augmentation, to expand current wild populations. 3.3 RECOVERY AND CONSERV A TION OF RAZORBACK SUCKER IN THE SAN JUAN RIVER AS A VIABLE PART OF THE NATIVE FISH COMMUNITY. 3.3.1 AVOID EXTIRPATION Preclude further adverse modification of rawrback sucker habitats and establish refugia. 3.3.2 RESTORE POPULATIONS If studies indicate augmentation is feasible, stock razorback suckers of appropriate lineage to establish a viable population in Ihe San Juan River. 3.3.3 REPRODUCfION Spawning of sufficient frequency and magnitude must occur to produce adequate numbers of offspring for recruitment to the adult population. Conditions must be provided for annual reproduction. Reproduction will be documented by capture of young-of-year specimens. 3.3.4 RECRUITMENT Regular recruitment of individuals to the reproductively active population is required for recovery and conservation. 3.3.5 RANGE AND ABUNDANCE Range and abundance must be increased above current levels to secure occupation of designated critical habitat and other suitable areas. 4.0 WNG RANGE PLAN OBJECTIVES Achievement of the objectives of the Long Range Plan are dependent upon successful accomplishment of identified research and management activities. While the endangered fish species are the focus of these needs, the overall status and health of the entire native fish 6
