The goal of the parties is' <br />to agree by October 1996. FWS takes the position that if <br />some agreement is not reached by that time, they will <br />operate under the authority provided in the Threatened and <br />Endangered Species Act and issue some decisions. <br />There are about 40 species of non-native fish currently <br />inhabiting the system and approximately 95% of the bio-mass <br />is of non-natives. Concerns of the water and energy <br />organizations in both basins are toward emphasizing this <br />imbalance and away from the environmental and ecological <br />damages caused by diversions, impoundments, water releases, <br />etc. <br />The process of looking at possible control processes <br />was started about 5 years ago. It quickly became apparent <br />that no one agreed what may be possible and, in any case, <br />did not want any control measures in their backyard. The <br />project moved to identify the most important exotic species <br />and principal areas inhabited with the objective of <br />controlling particular species and/or particular habitats. <br />The group has developed a document which should be available <br />in May for outside comment. The document discusses what <br />possible things can be done to prevent non-native fishes <br />from inhabiting or influencing the system. Priority areas <br />that seem to be reaching current consensus includes the <br />"minnow" fish habitat areas in the Middle Green River and <br />Nursery habitat areas in the Grand Valley. The primary <br />specie that is being looked at is the channel catfish. A <br />variety of control options includes commercial fisheries, <br />selective intensive removal in areas, and northern pike <br />removal below particular impoundments. Whatever the areas <br />are, they should be particularly controversial, and in local <br />areas, reach high levels of criticism. The idea is to <br />provide for experimental projects in 1997 depending on the <br />highest priority activities. There is definitive, but far <br />from conclusive, data available that non-natives are a <br />problem to the survival and well being of native fishes of <br />the main stem. <br />Comments from the Council included the position that if <br />non-native fish impacts to endangered fish are raised to the <br />same level as impacts of water release, water temperature, <br />diversions and power generation; the solutions to all these <br />issues must go forward at the same time or, if not, will not <br />result in a measurable increase in the animals. Also, the <br />document must consider who pays, what reasoning would <br />conclude that this would have any long term effect, and <br />especially how and who, as monitor, makes the overall <br />5 <br />1
