A report upon the Grand Coulee Fish Maintenance Project 1939-1947
The construction or Grand Coulee Dam, on the upper Columbia River, involved the loss of 1,140 lineal miles of spawning and rearing stream to the production of anadromous fishes. The fact that the annual value of these fish runs to the nation was estimated at $250,000 justified reasonable expenditures to assure their perpetuation. It was found economically infeasible to safely collect and pass adul

Removal of excess nitrogen in a hatchery water supply
The water system at the U. S. Fish Cultural Station, Leavenworth, Washington, has been supplemented with two wells that were to be used to increase the temperature of the water during the winter and to cool the Water in the summer if necessary. The well water proved to be unsuitable for hatchery purposes because it was supersaturated with nitrogen, causing "gas-bubble" disease among fish subjected

Effect of bait in live trapping Peromyscus
SUMMARY: Evidence from live trapping tests indicated that Peromyscus leucopus did not leave their home ranges because of the attraction of trap bait in nearby areas. A trap line down the center of a heavily live-trapped area caught as many mice before the area trapping as afterward. Thus, there was reason to believe that the area trapping did not serve to pre-bait the mice. Two unbait

The trap line as a measure of small mammal populations
SUMMARY: The value of a line of traps as a measure of relative abundance of small mammals was studied by field trials on Peromyscus leucopus populations. Comparisons were made between the numbers of mice captured by a line of live traps and the numbers captured in intensive live trapping of a larger area surrounding the line. Trials were made in bottomland woods where mice were numerous and in
