-18- <br />A small number of Eagle Lake strain rainbow trout were barged into <br />the Wyoming portion of the open hills area during the first week of <br />October. These fish were approximately 75 mm (3.0 in) TL when planted <br />and were marked with an adipose fin-clip. <br />Largemouth bass and threadfin shad were not stocked in 1977 because <br />of the poor results obtained from the previous plants. <br />Results <br />Stocking of salmonids in Flaming Gorge Reservoir has continued <br />because of insufficient natural reproduction. During 1977, a total of <br />4,119,190 advanced fingerling trout were stocked (Table 7). Of this <br />total, 3,719,606 were rainbow trout fingerlings averaging 130 mm (5.1 in). <br />TL. A total of 399,584 brown trout averaging 140 mm (5.5 in) were stock- <br />ed mainly in the inflow area at a rate of 60/acre in September. Distri- <br />bution of rainbow trout by areas was 37.8% canyon, 55.4% open hills and <br />6.7% inflow. This compares with average surface areas in 1977 as follows: <br />canyon 9,505 a (31%), open hills 15,330 a (50%) and inflow 5,825 a <br />(19%). Stocking rates (No/a ) for each area are presented in Table 7. <br />A total of 179922 Eagle Lake strain rainbow trout were included in the <br />rainbow plants in the open hills area. These were surplus rainbow from <br />the Wyoming State stocking program. <br />Approximately 80% of the fingerling planted in 1977 were barged <br />from seven boat ramps. Most of the fingerlings were stocked along the <br />shoreline of the lake in shallow water. Mortality due to transportation <br />and stocking the fingerlings was less than one percent. Losses to sea- <br />gulls and fish-eating ducks after planting probably equaled transporting <br />and stocking losses.
