Book excerpt: Excerpt from The Segregation of Red Salmon in the Escapements to the Kvichak River System, Alaska Chi-square tests of the hypothesis of like recovery distributions among four recovery points in 1957 and five recovery points in each of 1958 and 1959 gave values p=o.203, p and p respectively. It is significant that the high levels of p in 1958 and 1959 are associated with the strongest tests, i.e., more areas tested and greater numbers of recoveries. Since the values of p are high in all 3 years, segregation in time of passage at Igiugig is probably minimal. It is important, however, to consider whether these recoveries are representative of the single spawning groups (as defined) utilizing specific spawning grounds. On Copper and Iliamna Rivers the recoveries are surely representative of those systems. Figure 6.-recoveries by experiment, 1958, Kvichak River system. For explanation of figure, see legend to figure 5. Copper River recoveries were virtually all made by fri personnel during stream surveys well above the river mouth; Iliamna River recoveries by fri personnel and by personal use fishermen. Iliamna River is geographically isolated, and personal-use fishing is con ducted well inside the river so there should have been little doubt of the destination of tagged fish taken there.
