“…Valley confinement and reach type was categorized for each egg box by extracting these attributes from GIS data that were developed by Hill et al (2018). Briefly, Hill et al (2018) categorized the Panther Creek stream network into categories of confinement (unconfined, partly confined, and confined) following the framework that was outlined by O'Brien et al (2017). Reach types were classified by using four primary physical parameters: valley setting, channel planform, floodplain and in-stream geomorphic units, and the caliber of bed material (Rosgen 2002;Brierley and Fryirs 2005;Beechie and Imaki 2014).…”

Supplementing fish populations at the egg stage is a low‐cost alternative to hatchery rearing that is presumed to improve adaptation to local natural conditions. The Shoshone‐Bannock Tribes began supplementing Chinook Salmon Onchorynchus tschwytscha in Panther Creek, Idaho, at the eyed egg stage in 2014. The Chinook Salmon eggs were artificially fertilized and reared to eye‐up in the hatchery and then planted in custom‐made in‐stream incubators (egg boxes) for volitional release and natural rearing. Using data from three brood years, we evaluated the efficacy of this supplementation program solely in terms of juvenile production. We related juvenile production to the placement and retrieval of the egg boxes, assessed the relative contributions of offspring (parr and emigrants) from the egg boxes (HOR) to overall juvenile abundance, and compared the performance (length, condition, dispersal distance, and survival) of HOR versus natural‐origin (NOR) juveniles. Brood year and box placement within the stream (distance upstream) were the best predictors of whether or not an egg box was retrieved from its original location. Meanwhile, the condition of the box (i.e., intact, damaged, or missing) was the best single predictor of juvenile production. Supplemented eggs represented an estimated 42, 50, and 42% of the total egg deposition in Panther Creek in brood years 2014, 2015, and 2016, respectively. A parentage analysis revealed that the egg boxes accounted for 6, 22, and 35%, respectively, of the parr production for the respective brood years when the data were normalized to the estimated egg deposition—less than the egg‐to‐parr production that was estimated for natural redds. As fall parr, the HOR fish differed from the NOR fish in terms of their length and dispersal behavior, but they were of similar length and condition at their emigration from Panther Creek and exhibited no significant difference in downstream survival through the Federal Columbia River Power System (FCRPS). Collectively, our results provide useful insights to fisheries managers who are interested in initiating or refining egg supplementation programs.

“…We use the Brierley and Fryirs (2005) River Styles framework to model reach types, geomorphic condition, and recovery potential (O'brien and O'brien et al, 2017). Similar, promising frameworks could be potentially substituted for at least the reach-typing components (Bizzi and Lerner, Bizzi et al, 2013;Beechie and Imaki, 2014;Gurnell et al, 2015;Demarchi et al, 2016a, b;Kasprak et al, 2016), but here condition assessment and recovery potential are critical to addressing key management questions.…”

With high-resolution topography and imagery in fluvial environments, the potential to quantify physical fish habitat at the reach scale has never been better. Increased availability of hydraulic, temperature and food availability data and models have given rise to a host of species and life stage specific ecohydraulic fish habitat models ranging from simple, empirical habitat suitability curve driven models, to fuzzy inference systems to fully mechanistic bioenergetic models. However, few examples exist where such information has been upscaled appropriately to evaluate entire fish populations. We present a framework for applying such ecohydraulic models from over 905 sites in 12 sub-watersheds of the Columbia River Basin (USA), to assess status and trends in anadromous salmon populations. We automated the simulation of computational engines to drive the hydraulics, and subsequent ecohydraulic models using cloud computing for over 2075 visits from 2011 to 2015 at 905 sites. We also characterize each site's geomorphic reach type, habitat condition, geomorphic unit assemblage, primary production potential and thermal regime. We then independently produce drainage network-scale models to estimate these same parameters from coarser, remotely sensed data available across entire populations within the Columbia River Basin. These variables give us a basis for imputation of reach-scale capacity estimates across drainage networks. Combining capacity estimates with survival estimates from mark-recapture monitoring allows a more robust quantification of capacity for freshwater life stages (i.e. adult spawning, juvenile rearing) of the anadromous life cycle. We use these data to drive life cycle models of populations, which not only include the freshwater life stages but also the marine and migration life stages through the hydropower system. More fundamentally, we can begin to look at more realistic, spatially explicit, tributary habitat restoration scenarios to examine whether the enormous financial investment on such restoration actions can help recover these populations or prevent their extinction.

A network model for primary production highlights linkages between salmonid populations and autochthonous resources

Abstract. Spatial variation in fish densities across river networks suggests that the influence of food and habitat resources on assemblages varies greatly throughout watersheds. Conceptual models predict that in situ primary production should vary with river characteristics, but the influence of autochthonous resource availability on the capacity for river reaches to support fish is poorly understood. We estimated primary production throughout the South Fork and Middle Fork of the John Day River, Oregon, by measuring diel cycles in dissolved oxygen (DO) during July 2013. Using these data, we (1) evaluated the extent to which juvenile salmonid abundance and resource limitation correlated with areas of high gross primary production (GPP), (2) developed models to predict GPP from both site-level measurements and remotely sensed data, and (3) made predictions of GPP across the entirety of the Middle Fork John Day River (MFJD) network and assessed the utility of these spatially continuous predictions for describing variation fish densities at broad scales. We produced reliable estimates of GPP at sites where DO loggers were deployed using measurements of solar exposure, water temperature, and conductivity measured at each site, as well as surrogates for these data estimated from remote sensing data sources. Estimates of GPP across fish sampling sites explained, on average, 58-63% of the variation in juvenile salmonid densities during the summer sampling period, and 51-83% during the fall sampling period, while continuous network predictions of GPP explained 44% of the variation in fish densities across 29 km of the MFJD. Further, GPP explained nearly half of the variation in juvenile steelhead dietary resource limitation, as inferred from bioenergetics modeling results. These results comprise a first effort at quantifying variation in autochthonous production across an entire river network and, importantly, provide a much-needed food-web context for guiding more effective fish and habitat management.
