-6- <br />The USFWS position states that the Federal service has only responsibility for <br />federal impacts as far as mitigation. <br />Lee Mills is interested in reconvening the warmwater hatchery task force, possibly <br />in conjunction with Colorado River Wildlife Council Technical Committee meetings <br />with the objective that a plan could be developed in which each state could <br />participate. <br />Action: Recommend Council endorse a standing committee to continue work on this <br />subject. Committee should consist of members from Utah, Colorado, Arizona, Nevada, <br />and New Mexico. <br />Grass Carp - Tom Jackson, USFWS <br />A slide presentation was given regarding the feeding and requirements of the grass <br />carp, a species on the Council's recommended prohibited list. Jackson presented <br />data to demonstrate that specific requirements for reproduction were not present <br />in the Colorado River. <br />During the discussion following the presentation it was pointed out that promoting <br />grass carp results in pressure by water districts to introduce the fish, believing <br />it to be the panacea for weed control. It was also pointed out to Jackson that <br />once an exotic such as grass carp is released, there is no way to take it back, <br />and we are now experiencing the prolific spread of an introduced exotic (tilapia) <br />in the Colorado River that researchers had "demonstrated" could not reproduce in <br />` the river. <br />Iilapia - J. A. St. Amant <br />A report was given on the known status of tilapia in California. Today's classic <br />example of what can happen when an exotic is released is starting to be revealed. <br />An unidentified species of tilapia has become well established in the Salton Sea. <br />Despite winter kills of thousands of tons of these fish, it continues to provide <br />a thriving sportfishery and an illegal commercial fishery. However, it has displaced <br />the only native fish (desert pupfish) in many areas. Another species of tilapia <br />has displaced native fishes in at least several coastal waters. Various species <br />of tilapia are well established in the lower Colorado River and appear to be <br />spreading north. The impact to the Colorado River ecosystem has yet to be determined <br />(report enclosed). <br />The P and P Committee has been assigned by the Technical Committee to investigate <br />the status and impacts of tilapia and provide recommendations. A meeting of the <br />Committee is scheduled prior to the next Subtechnical Committee meeting. <br />Summary of Actions to.Council <br />1. Presentation to Council from Bill Parsons, Nevada, regarding Interstate <br />Boundary Waters Enforcement Problems. Summary report to accompany Task minutes. <br />2. Summary report presentation from Rod Stone to Council on Acid Rain in Upper <br />basin.
