Utah Division of Wildlife personnel conducting the scheduled spring monitoring work. This should faci'li'tate broodstock collection with the least amount of effort and duplication of sampling. Sampling by the three agencies will be conducted between Rifle, CO and 'the confluence of the Colorado and Green Rivers. Capture methods will consist of seines, trammel nets, trap nets, electrofishing and/or a combination of these methods. Care should be taken to handle the fish as little as possible. Likewise, the amount of time the fish is out of the water should be kept to an absolute minimum. Upon capture the fish should be placed into an aerated live well or large (100-150 qt.) corder equipped with oxygen, regulator and carbon diffuser. These holding containers in the boat should contain river water and a 0.59 salt solution (by weight of water). The salt solution will help mitigate the loss of blood electrolytes due to handling stress. If more fish are captured than can be adequately held in the holding tanks, the net cribs will be used to hold fish in the river. Likewise, if fish need to be held overnight before the distribution unit arrives, net cribs in the river will again be used. Common sense and good judgment need to be exercised at all times. _F•ield personnel are given complete discretion to determine the feasibility of successfully transporting 'these wild fish. if the researcFier determines that the risks involved in a particular situation are too great, the fish should be returned 'to the river. The Fish and Wildlife Service (Grand Junction CRFP office) will be responsible for hauling fish from the river take-out points to dexter NFFI, Dexter, New Mexico.
