| Abstract | Juvenile chum salmon (Oncorhynchus keta ) resided in Netarts Bay, a small, shallow estuary at the southern spawning range of chum salmon in the Northeast Pacific, from mid-March until June during each of three years from 1984 to 1986. Early in the spring they were most abundant in beach seine catches during high tide in the upper bay, indicating extensive intertidal excursions. Later in the spring, when temperatures exceeded 14 degree -16 degree C in the upper bay, they were most common in catches at low tide in the lower bay. Based on recaptures of fin-clipped hatchery fish, the residence of juveniles varied inversely with size of fish at release. Large (6.5 g) fish immediately emigrated from the estuary and 3-4 times as many returned as adult fish as 1.0 and 2.2 g juveniles, which had residence half-lives of 5-16 days |
| Notes | Studied juvenile chum salmon in Netarts Bay from mid-March through June from 1984 to 1986. Smaller juveniles were more likely to use the estuary as a safe place to grow larger before entering the ocean. Conducted experimental releases of hatchery-raised chum salmon of differing sizes. Larger juveniles did not stay in the estuary, but migrated into the ocean. Suggest factors that may affect growth and rearing strategies. |
