Show Springville hatchery takes part in walleye spawn eaq hatching taken during spawning operations opera-tions was less than 50rr, this initial effort is encouraging. A local source of walleye may be on its way to being developed de-veloped following moderately successful hatching of walleye eggs taken from spawning fish in Willard Bay by the Utah Division of Fish and Game. Development of proper techniques tech-niques of getting the eggs from the "green" stage to the "eyed" stage is the biggest problem facing technicians in developing the methods of hatching out walleye eggs under conditions at Utah hatcheries. Fishery workers took about four million eggs from spawning spawn-ing fish at Willard Bay and the eggs were taken to Scott Avenue Ave-nue Hatchery and Springville Hatchery where they were put into special hatchery containers.. contain-ers.. It was about seven days before be-fore the eggs developed to the "eyed" stage and six days to hatch, for about 13 days total time from delivery to the hatchery to hatching. Over 800,000 walleye were stocked in the lower Bear River Ri-ver from the Scott Avenue Hatchery and 700,000 stocked in Yuba Reservoir from the Springville Hatchery. Walleye are stocked immediately immed-iately after hatching because of losses which occur from these fish feeding on each other when crowded up in hatcheries. Although the percentage of eggs hatching out of the total |
