We report on juvenile steelhead rearing and release activities for the 2002 brood year (BY) released in 2003. Included are collection, spawning, and adult characteristics for the 2003 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. In general, the data in this report were derived from hatchery inventories and standard databases (i.e., Pacific States Marine Fisheries Commission Regional Mark Information System (RMIS), ODFW mark recovery) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in the 2003 work statement (Carmichael et al. 2003). Coded-wire tag (CWT) data that were collected from 2003 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2003, experimental treatments from which fish returned included forced vs. volitional release, and a pre-smolt release strategy. In 2003, the experimental fish were released to evaluate acclimated vs. direct stream release strategies. We also released non-clipped, blank-wire tagged, and unmarked, untagged steelhead. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment, which will be published in special reports. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River Basin.

We report on juvenile steelhead rearing and release activities for the 2004 brood year (BY) released in 2005. Included are collection, spawning, and adult characteristics for the 2005 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. In general, the data in this report were derived from hatchery inventories and standard databases (e.g., Pacific States Marine Fisheries Commission Regional Mark Information System (RMIS), ODFW mark recovery) or through standard measuring techniques.

Additional descriptions of protocols can be found in our work statements (Carmichael and Hoffnagle 2004, Carmichael et al. 2005c, Carmichael et al. 2005d). Coded-wire tag (CWT) data that were collected from 2005 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2005, experimental treatments from which fish returned included forced vs. volitional release, a pre-smolt release, non-clipped, blank-wire tagged release, and off-station direct-stream release strategies. In 2005, experimental fish were released to evaluate progeny from early returning (fall-collected) broodstock vs. production broodstock. We also released non-clipped, blank-wire tagged smolts, and two groups (marked and unmarked/untagged) of off-station direct stream release smolts, to compare to production releases. Analysis of specific survival studies will be completed and published in separate reports once all brood years have returned and CWT data are complete for a given experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River Basin.

We report on juvenile steelhead rearing and release activities for the 2010 brood year (BY) released in 2011. Included are collection, spawning, and adult characteristics for the 2011 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. In general, the data in this report were derived from hatchery inventories and standard databases (e.g., Pacific States Marine Fisheries Commission Regional Mark Information System (RMIS), ODFW mark recovery) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in our work statements (Carmichael et al. 2009, Carmichael et al. 2010). Coded-wire tag (CWT) data collected from 2011 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2011, experimental treatments from which fish returned included unmarked releases, off-station direct-stream releases, and progeny from early returning (fall-collected) broodstock release strategies. In 2011, experimental fish were released at Wallowa Hatchery to continue evaluation of progeny from early returning (fall-collected) broodstock vs. production broodstock. Methods for the fall broodstock experiment are described in Warren et al. (2011). Analysis of specific survival studies will be completed and published in separate reports once all brood years have returned and CWT data are complete for each experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin.

  Citation × Citation Citation Abstract Copy Title: Catherine Creek Spring Chinook Salmon Hatchery Program Review - 2011 Abstract -- This paper provides background information, program development history, and an assessment of program performance for the Catherine Creek spring Chinook salmon hatchery program. We cover the time period from initiation of the program in the mid-1990s to present. General background information and pre mid-1990s hatchery program performance were previously presented in Grande Ronde Basin Spring Chinook Salmon Hatchery Review: Introduction and the Early Years. The Catherine Creek spring Chinook hatchery program was initiated with collection of wild parr for the Captive Broodstock Program in 1995 due to the depressed status of this population (Figure 1). Adult trapping and smolt acclimation facilities were constructed to implement the program and are operated by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). These facilities function as satellite facilities of Lookingglass Fish Hatchery (Figure 2). Lookingglass Fish Hatchery (LFH) serves as the adult holding, spawning, incubation, and rearing facility for the program. Smolts are transported from LFH to the Catherine Creek acclimation ponds for a short period of acclimation in the spring prior to release. Annual adult mitigation, smolt production, and brood year specific smolt-to-adult return goals were developed for the Catherine Creek program to represent 16.67% of the total Grande Ronde River basin goals (Table 1).

  Citation × Citation Citation Abstract Copy Title: Migration Characteristics of Hatchery and Natural Spring Chinook Salmon Smolts from the Grande Ronde River Basin, Oregon, to Lower Granite Dam on the Snake River Abstract -- Smolts of spring Chinook salmon Oncorhynchus tshawytscha experience substantial mortality while migrating through free-flowing reaches of the Snake River basin before reaching Lower Granite Dam, the first dam encountered in the Columbia–Snake river hydrosystem. We investigated the patterns of travel time and survival of hatchery and natural smolts fitted with passive integrated transponder (PIT) tags through specific reaches of the migration corridor during the 2000–2006 migration years for two populations originating in the Grande Ronde River basin (Lostine River and Catherine Creek). For both populations, median travel times for natural smolts were significantly longer in the upper reaches of the migration corridor but shorter in the lower reaches than for their hatchery counterparts. Also, among both hatchery and natural smolts, smaller individuals spent more time in the upper reaches, presumably feeding to attain a larger size before continuing their migration. Within populations, both hatchery and natural smolts showed similar patterns of survival through the reaches of the migration corridor above Lower Granite Dam. Size-selective mortality was evident for hatchery and natural smolts from both populations, especially in the upper reaches, larger individuals experiencing higher survival. The Catherine Creek population experienced the majority of natural and hatchery smolt mortality (32.8–65.8%) in a relatively short (91-km), low-gradient reach immediately below the summer rearing habitat. In contrast, the Lostine River natural and hatchery smolts experienced lower mortality (3.6–46.1%) in a 174-km reach below the summer rearing habitat. The results of this study demonstrate the dynamic nature of survival and migration rate among spring Chinook salmon smolts during their initial seaward migration from tributaries.
