• Description:
  Straying was studied in the fall of 1977 by the capture of adult
  
  salmon in traps built into weirs constructed at the mouths of Jolly
  
  Giant Creek (home stream) and Jacoby Creek (adjacent stream). No salmon could pass the weir on Jolly Giant Creek, but in Jacoby Creek salmon could pass the weir during periods of high water Escapement to
  
  Jolly Giant Creek was 0.30 percent of smolts released. An estimated 0.25 percent of the smolts released into Jolly Giant migrated to Jacoby Creek as determined from adult fish trapped at the weir and recovered by electrofishing. These data showed a rate of straying of about 45
  
  percent as based on adults recovered in the two streams. A majority of the 3-year-old coho returning to Jacoby Creek in the fall of 1977 came from smolts released into Jolly Giant Creek. Improvement in the homing of smolts in the Jolly Giant Creek area may be improved by use of organic fractions in domestic wastewaters to be passed through two marshes and a lake to operate "imprinting ponds."
