Salmon strays per stream (males and females combined).
Coho Salmon return 2–7 years after hatching of the first cohort (Fig. 5.5). Coho
Salmon produced the lowest stray densities of the three species examined. Coho
have a shorter life span and return over just a 2-year period. Thus, the stocking
program produces returns over a shorter period of time, and the stray density
cumulative density functions (CDF) show less annual variation. In year 2, all the
