Main Portion

The spawning runs of pink salmon to McClinton creek, Masset inlet, B.C., in 1930, 1932, 1934, and 1936, differed little in time of appearance of the first migrant and disappearance of the last. The period occupied for the main portion of each run to reach the spawning beds depended chiefly upon rainfall and freshet conditions. Males occurred in greater numbers at the beginning of every run but a subsequent increased influx of females eventually brought about equality of the sexes in two seasons. In the third the males predominated slightly, and in the fourth the females. The average length and weight of males are consistently greater than those for females in the same year. Usually a significant increase in length occurred in both sexes from the commencement to the end of the run. In some cases a similar gain in weight was demonstrated but in others it was apparently masked by loss in weight consequent upon fasting during the spawning migration. The number of eggs per female in a given year increases with increase in length and weight.

The Relationship

Through the medium of specially-designed counting fences, records have been maintained of the adult pink salmon, Oncorhynchus gorbuscha, spawning in McClinton creek, Masset inlet, B.C. from 1930 to 1942, of the eggs available for deposition each season and of the fry resulting from these eggs. A loss of 76.2 to 93.1 per cent of the potential egg deposition occurs between the time of upstream spawning migration and the egress of the fry to sea. This mortality is assigned to a number of factors, some of which are briefly discussed. Within certain limits and under reasonably uniform climatic conditions smaller egg depositions provide greater efficiencies of hatch (percentage relationship of numbers of fry migrants to potential egg deposition). There thus appears a tendency toward rebuilding the run, herein termed "resilience," and believed to be closely bound up with the relationship between the fish and its physical and biological environment.
