The straight line represents a ratio of 1 to 1. SEAWARD MIGRATIONS The seaward migration of Karluk River red salmon takes place during the last week of May and the first 2 weeks of June each year. A few fish migrate sometimes a day or two earlier or later than this period but the major part of the migration, and frequently the entire migration, takes place during these 3 weeks. During the migration period the seaward migrants can be observed in front of the counting weir where they congregate in schools of a few hundred to tens of thousands. Only occasionally can they be seen going through the weir during the daytime, but just at dusk the schools above the weir drop downstream and begin to pass through the spaces between the pickets. Where there is any appreciable current, the fish always head upstream even when migrating downstream. Seaward migrants are present in the river above the weir for only 10 to 16 days each year, although the migration period may extend over a period of 3 weeks. They may be quite abundant one day, entirely absent the next, and present again the following day. The percentage occurrence of the various age groups in the random samples of seaward migrants collected at the weir site is presented in table 26. Samples were not collected every day that migrants were present in the river, but since 1930 samples have been taken every day that fish were abundant. /
