Juvenile Chinook Salmon Oncorhynchus tshawytscha moving downstream through tributaries of the upper Willamette River basin can spend months in reservoirs created by dams. While residing in the reservoirs, they often obtain heavy infections of the freshwater parasitic copepod Salmincola physiologic effect these parasites have on salmonids is poorly understood. Chinook delay downstream migration (Buchanan and Skalski ). Estimates of juvenile survival based on this model consider the joint probability of migration and survival; however, for fall Chinook salmon, the probability of migration is unknown. These juveniles may migrate throughout the year, but detection systems at the dams are.
It has recently been demonstrated that a large percentage of yearling Chinook salmon Oncorhynchus tshawytscha smolts released from a production‐scale hatchery on the Yakima River display an underappreciated life history strategy. Instead of migrating to the ocean for long‐term rearing and growth, males may instead undertake a short‐term migration downstream, turn around, and migrate back. A new acoustic telemetry system tracks the migration of juvenile salmon using one-tenth as many fish as comparable methods, suggests a .
conditions for adult and juvenile Chinook salmon, including continued trap, transport and release of adult salmon into above-dam habitats (Reasonable and Prudent Alternative [RPA] ), and studies to investigate the feasibility of improving downstream fish passage at . While many Chinook salmon fry migrate rapidly to tidal delta and nearshore habitats to rear, trapping studies have shown that on a given year 20% to 60% of Chinook salmon fry spend enough time rearing in freshwater habitats to exhibit growth (see Figure below).

At the downstream RST (GOLF), the first juvenile Chinook salmon was captured on 19 January Thirteen trap efficiency tests using hatchery produced and naturally produced Chinook salmon were conducted at GOLF during the monitoring period. Eight of those tests were used to calculate the total estimated abundance of naturally produced.

This report provides data and assessment of the downstream migration of juvenile fall-run chinook salmon and steelhead, physiological smolt indices, and mark-recapture experiments of hatchery-reared juvenile salmon migrating through the Sacramento-San Joaquin Delta during the winter, spring, and summer seasons of During the spring and summer of –04, we sampled the downstream migrations of fishes in the Yukon River mainstem near the Canada-U.S.
border, using a rotary auger trap. Age-0 juvenile chinook salmon, Oncorhynchus tshawytscha, were the most common fish in the catch, and they peaked in abundance in mid-June.

Juvenile Chinook salmon were captured each winter and spring using a m diameter rotary screw trap (RSTR) located near the base of the Yolo Bypass floodplain from to (Fig.

Juvenile migration and residency We established a mark and recapture program during e to monitor the downstream migration of juvenile salmon and the upriver origin of individuals in the estuary. Fish traps were placed immediately downstream of three principal Chinook salmon spawn-ing areas to capture and mark juveniles (Fig.

Subjecting yearling spring chinook salmon to advanced photoperiods for 3 months prior to release resulted in greater smolt development and more rapid downstream migration.

Juvenile salmon are released in the Sacramento and San Joaquin rivers and tributaries (from km from the diversions); however, they are not vulnerable to entrainment until they enter the tidal Delta.
A study of salmon migration with acoustic telemetry indicated juvenile salmon migrated through the Delta in days on average.
Gill Na +,K +-ATPase activity was determined on three occasions (11 May, 30 May, 11 July) from PIT-tagged 2-year-old brown and sea trout (Salmo trutta), whose smolt migration was monitored in an annular flume these three occasions, gill Na +,K +-ATPase activity was highest at the end of May coincidentally with the highest activity of downstream migration.
