Abstract
Investigation of effect of a proposed hydro‐electric development on the salmon spawning grounds in Jones Creek, British Columbia in 1949 indicated spawning areas would be so affected that only a small portion of existing runs could be maintained. Methods for preserving the run were suggested and one selected that involved the construction of an artificial spawning channel capable of supporting the existing runs with provision for controlling the flow in the channel and by‐passing surplus flows. Behavior studies of pink salmon (Oncorbynchus gorbuscha) and chum salmon (O. keta) spawning in the channel were made in 1955 and the survival from egg to fry was determined in 1956 when there was survival of 37 percent of the 428,000 pink salmon eggs calculated to have been available for deposition and 30 percent of the 251,000 chum salmon eggs calculated to have been available for deposition.This publication has 0 references indexed in Scilit:
