“…Therefore, if the appropriate temperatures to use in a model of emergence could be determined, the prediction of when the fish will emerge would be fairly straightforward. However, our research over the past several years in the Ives Island area suggests a large difference between river temperature and the temperature at the locations where chum salmon eggs/embryos are placed (Arntzen et al 2008a(Arntzen et al , 2009b. In the Ives Island area, there can be significant variations in riverbed temperature within a fairly small area, and this variation in temperature is a function of the spatial heterogeneity of riverbed sediments, groundwater inputs, and tailwater fluctuations (Geist et al 2002Arntzen et al 2009a).…”

“…The state water quality standard used to provide protection for preemergent chum salmon rearing in the gravel has been to limit TDG to 105% after allowing for depth compensation, i.e., TDG in the river could be as high as 115% assuming three feet of water depth over the redds (NOAA 1995). The results of a 3-year study conducted from 2006 through 2008 suggested that if water depth over redds in the Ives Island area remained greater than 3 feet deep, then depth compensated TDG remained below 105% (Arntzen et al , 2008a(Arntzen et al , 2009b. However, there were times during the study when adequate depth compensation was not always provided, especially to redds spawned at relatively high riverbed elevations.…”

“…The relationship between ATUs and emergence of salmonids is well documented (Piper et al 1989). Specific to chum salmon, the Pacific Northwest National Laboratory (PNNL) has conducted 2 years of laboratory studies with chum salmon in which researchers documented the range of emergence and the ATU values that corresponded to this range of emergence (Arntzen et al 2008a(Arntzen et al , 2009b. In addition, the Washington Department of Fish and Wildlife has considerable information on this subject from its work with lower Columbia River chum salmon (Hillson 2003).…”

“…The 825-ATU value has been used in the past as representative of the earliest onset of emergence in the Ives Island area (personal communication with Todd Hillson, WDFW, as cited in Arntzen and Murray 2011). We chose to use 932 ATUs as the threshold of emergence because it represented when 50% of the fry from a local chum salmon stock emerged in a controlled study conducted in our laboratory in 2007 and 2008 (Arntzen et al 2008a(Arntzen et al , 2009b. In those studies, we documented 50% emergence of untreated fish over a range of 917 to 959 ATUs and 100% emergence of untreated fish over a range of 967 to 975 ATUs (PNNL, unpublished data).…”

“…Our laboratory research from 2007 and 2008 showed that 50% emergence of chum salmon occurred at an average of 932 ATUs (range 917 to 959 ATUs; Arntzen et al 2008aArntzen et al , 2009b. The ATUs measured at the time of emergence were based on studies conducted with hatchery chum salmon in our laboratory where we documented the ATUs to the date (±1 day) when 50% of the embryos emerged from emergence tubes.…”

SummaryThe objective of this project was to develop a conceptual model for the U.S. Army Corps of Engineers, Portland District, that can be used to predict the timing of chum salmon (Oncorhynchus keta) emergence in the Ives Island area. Researchers at the Pacific Northwest National Laboratory developed the model using real-time hourly temperature data from three locations in the Ives Island spawning area that were instrumented with paired hyporheic and river sensors beginning in 2003. These data were supplemented by additional temperature data collected in the Ives Island area during 2006-2007, including 5 additional paired hyporheic and river sensors and 32 hyporheic sensors that measured temperature at approximately 15 cm below the bed surface of the Columbia River.Using these data, we calculated accumulated thermal units (ATUs) for each sensor location; we assumed emergence occurred at 932 ATUs based on the time to 50% emergence in previous laboratory studies. We found that mixing various proportions of hyporheic and river temperature data from the realtime sensors could be used to reproduce the number of days to emergence for the full range of sensor locations in [2006][2007]. The number of days to emergence that were mapped in the Ives Island area were spatially coherent, with much shorter time to emergence in the western part of the channel relative to more easterly parts of the channel. These results are similar to those of earlier studies showing that bed temperatures in the Ives Island area tend to be spatially continuous and mappable and that cooler hyporheic water is found in the eastern part of the channel.A pre-season estimate of emergence dates is determined by interpolating the days to emergence for each redd location from the map of 2006-2007 redds and temperatures. The map is then used to identify the mixture of hyporheic and river temperature data from the real-time system that would provide the closest match for the estimated days to emergence for each redd location. The identified mixture is then used to update the emergence estimates for each redd during the incubation season as new hyporheic and river temperature data become available from the real-time system. This method assumes that the spatial distribution of areas with warm and cool hyporheic temperatures near Ives Island tends to be relatively constant, as suggested by the results of earlier mapping studies. A case study was prepared using redd location data from 2009-2010 to illustrate use of the conceptual model. The case study showed differences in emergence estimates resulting from variations in the river and hyporheic temperatures from year to year.

Several superhigh dams (greater than 200 m in height) and many high dams have been built in the upper Yangtze River basin in recent years, and these dams have made total dissolved gas (TDG) supersaturation a serious environmental problem. A few studies have examined the tolerance and avoidance characteristics of rare and endemic fish in TDG‐supersaturated water in the upper Yangtze River over the past 10 years. These studies focused on specific species and specific sizes and did not identify a regular pattern that can be applied to all resident fish in the upper Yangtze River. However, elucidating this type of pattern is crucial for fishery management and dam operations in the upper Yangtze River. Data on the median lethal time (LT50), horizontal avoidance percentage, and vertical water depth of three rare and endemic species in the upper Yangtze River from previous studies were used in the current work. An exponential relationship was found between LT50 of fish and TDG supersaturation. The avoidance percentage of fish has a linear relationship with TDG supersaturation. Fish in the upper Yangtze River can use depth compensation to avoid the threat of TDG when the saturation is 130% or above but rarely avoid the threat of TDG when the saturation is less than 125%. We also described the tolerance and avoidance characteristics of fish in a TDG‐supersaturated river downstream from a super‐high dam. When the dam discharged a two‐year flood, the LT50 values of fish downstream ranged from 9.1 to 27.5 hr regardless of depth compensation. The avoidance percentage of resident fish ranged from 8.4 to 44.8%. The resident fish swam to a water depth of 2.43–3.33 m to avoid the threat of TDG.

Supersaturated total dissolved gas (STDG) caused by the flood discharge can result in bubble disease and even fish death, posing potential risks to aquatic ecosystems. In order to reduce the impacts of STDG on such ecosystem, a dynamic multi‐objective STDG management model (DMO‐STDGM) with the flood pulse discharge pattern is developed based on the prototype observation and laboratory test analysis, which consists of STDG prediction, fish safety assessment, multi‐objective optimization and 2‐D STDG transport diffusion simulation modules. The proposed model can support generation of flood pulse discharge patterns to reduce the level of STDG and minimize the maximum residence time of STDG water. The developed model is applied to optimize the discharge pattern of Xiluodu project to reduce the effects of STDG on fish. Simulation results of the worst scenario with the flood pulse discharge pattern show that the maximum residence time of STDG for T120%, T125%, T130%, and T140% are 12, 9, 4, 3 and 1 h, which are less than the corresponding LT50s (Mean Lethal Time). It means that the physiological function of fish can recover from the affect of STDG, thus fish can survive in the worst scenario. The established model can also be employed for increasing power generation. Simulation results indicate that the flood pulse discharge pattern with equal weight of ecology and power generation can ensure full load operation of hydropower station with 12,600 MW. The established model is widely applicable and can provide an important theoretical and technical support for water quality and ecosystem management under multiple complexities.
