| A | 97616 | 165 | Produce Environmental Compliance Documentation | Ensure environmental compliance requirements have been met | Provide BPA with information necessary for environmental clearance for all contract activities during FY12. Submit FY13 SOW and supporting documents as needed for BPA's Environmental Compliance Group to determine environmental compliance status. | $500 | 0.18% | 06/01/2012 | 05/31/2013 |
| B | 97618 | 157 | Collect/Generate/Validate Field and Lab Data | Collect smallmouth bass for abundance estimation | Smallmouth bass will be collected to estimate their abundance in the Hells Canyon Reach of the Snake River. The river will be divided into upper and lower reaches for sampling with the Salmon River confluence serving as the dividing line. A stratified random sampling design, based on river gradients and canyon topography will be used to select shoreline sampling transects in the two sections of the river. The river will be divided into three strata: open, canyon, and chute. The open strata will be defined by gradients >1.50 m/km and longitudinal slopes <25°. The canyon strata have gradients between 1.00-1.50 m/km and slopes of 26-33°. The chute will be defined by gradients >2.00m/km and a slope >34°. We will sample six randomly selected longitudinal, shoreline transects measuring between 325 m and 1,165 m in length in each section, comprising approximately 9% of the length of the upstream section and 8% of the downstream section. In the upstream section, we will sample two longitudinal transects in the open strata (out of a total of 15 longitudinal transects), three longitudinal transects in the canyon strata (out of a total of 23 longitudinal transects), and one longitudinal transect in the chute strata (out of a total of 5 longitudinal transects). In the downstream section, we will sample six longitudinal transects (out of a total of 66 longitudinal transects) using a simple random sampling design, as all of the downstream section is open habitat type. We will collect fish along transects in early fall using boat electrofishing. After fish are tagged (see Work Element C), we will sample again a minimum of 1 week later to recapture tagged fish along the same transects. The goal will be to collect at least 500 fish on the first sampling trip and 100 recaptured tagged fish on the second sampling trip. | $25,000 | 9.15% | 06/01/2012 | 10/30/2012 |
| C | 97617 | 158 | Mark/Tag Animals | Floy tag smallmouth bass in Hells Canyon | Smallmouth bass will be tagged in the Hells Canyon Reach of the Snake River to estimate their abundance using a mark-recapture analysis. Estimating the number of bass in Hells Canyon is a necessary step to subsequently estimating the loss of juvenile fall Chinook salmon to bass predation. Smallmouth bass collected under Work Element B will be externally tagged with a Floy tag along the back at the base of the dorsal fin. The goal will be to tag as many fish as possible with an expected number of 500 fish. | $10,000 | 3.66% | 06/01/2012 | 09/30/2012 |
| D | 97622 | 162 | Analyze/Interpret Data | Estimate smallmouth bass abundance | To estimate the abundance of smallmouth bass, we will use recapture data from tagged smallmouth bass in the program MARK (White and Burnham 1999) to estimate abundance of two size classes of fish (170-249 mm and 250 mm) in each study reach using the Jolly-Seber-Lambda model within the MARK program. We will use an open population model in each reach to account for fish movement, natural and fishing mortality, and recruitment of smaller fish into the 175 mm size class over our study period. We will calculate survival probabilities, capture probabilities, and initial population sizes and corresponding confidence intervals. We will also calculate CPUE and fish densities by dividing population estimates by the surface areas of each study reach. Surface area estimates will be obtained from the Idaho Power Company. We will compare abundance of smallmouth bass between study reaches using analysis of variance. | $27,000 | 9.88% | 06/01/2012 | 01/31/2013 |
| E | 97619 | 157 | Collect/Generate/Validate Field and Lab Data | Collect smallmouth bass diet data | Smallmouth bass will be captured biweekly from late April through mid July in the Hells Canyon Reach from Pittsburg Landing to Asotin, WA. Electrofishing will be used to collect smallmouth bass, and the shocker will be set at 600 V DC (60 pulses/s) to produce 3-4 amps in the water. Smallmouth bass will be collected along the same transects described Work Element B. Fish will be collected in the early morning or in the evening before sunset when smallmouth bass are most likely to move into shoreline areas. Nighttime electrofishing will not be used as it is too hazardous in Hells Canyon. Collected bass will be weighed and have their stomach contents removed by non-lethal lavage. Stomach contents will be preserved for later analysis. Similar sampling conducted in the mid 1990s resulted in about 1,200 smallmouth bass being collected over the same time frame of our proposed sampling. Therefore, we set a goal of collecting 200 fish during each biweekly sampling (N = 6) for a total of 1,200 fish for the season. | $50,000 | 18.30% | 06/01/2012 | 05/31/2013 |
| F | 97623 | 162 | Analyze/Interpret Data | Analyze smallmouth bass diets | Stomach contents of smallmouth bass will be identified to lowest practical taxon using a dissecting microscope. Diet items will be placed into four categories: fish, crayfish, macroinvertebrates, and other prey (e.g., mollusks, plant material). Each prey in each dietary category for each smallmouth bass will be blotted dry and weighed to the nearest 0.01 g. Intact prey fish will be measured (fork length) and original weight will be estimated with a length-weight regression. Prey fish that are too digested to measure will be processed by the methods of Ward et al. (1995) to isolate diagnostic bones for identification and to estimate prey fish size. Diagnostic bones (dentaries, cleithra, and pharyngeal arches) will be examined under a dissecting microscope and fish will be identified to the lowest possible taxon (Hansel et al. 1988). We will count the number of prey fish eaten by adding the number of paired diagnostic bones to remaining unpaired bones. Smallmouth bass diet data will be summarized on a prey weight basis to determine the monthly percentages of each prey taxa consumed. Prey fish will be separated into salmonids and nonsalmonids. Smallmouth bass diets (e.g., proportions of different dietary items) will be compared between reaches (i.e., upper and lower) and months (i.e., April, May, June, July) using chi-square analyses. | $100,000 | 36.59% | 06/01/2012 | 05/31/2013 |
| G | 97624 | 162 | Analyze/Interpret Data | Estimate fall Chinook loss to predation | We will calculate consumption indices (Ward et al. 1995) for smallmouth bass and compare them across study reaches, months, and years using ANOVA. For each study reach and month, we will estimate the total daily ration of smallmouth bass using the methods of Zimmerman (1999).
To estimate subyearling loss to predation by smallmouth bass, we will estimate daily consumption of smallmouth bass using a simple meal turnover-time adapted from Adams et al. (1982) and modified by Naughton et al. (2004):
C = n / N;
where: C = consumption rate of subyearling fall Chinook salmon (prey/smallmouth bass/day),
n = number of subyearling fall Chinook consumed within 24 h of capture, and
N = total number of smallmouth bass sampled (including empty stomachs).
Weights of digested fall Chinook salmon at collection will be compared to estimated weights of live fish derived from regression equations (Vigg et al. 1991) after a 24-h digestion period. Prey weights heavier than estimated live weight after a 24-h digestion period will be included in the calculation of a daily consumption rate. Prey weights lighter than the calculated live weight after 24-h digestion will not be used in the calculation of daily consumption rates, because we will assume those prey fish may have been consumed during a period greater than 24 h. To estimate the portion (g) of the meal evacuated from the stomach of smallmouth bass (E), we will use the algorithm from Rogers and Burley (1991):
E = S• ;
where: E = weight evacuated (g),
t = time (hours),
S = meal weight (g),
T = temperature (°C) at capture, and
W = smallmouth bass weight (g).
The meal weight will be calculated by the method of Vigg et al (1991):
S = Oi + Oj + Dk,
where: S = meal weight (g),
Oi = the calculated original weight of fall Chinook salmon at ingestion,
Oj = the calculated original weight of any other prey fish that was digested that was within 10% of the
original weight,
Dk= the digested weight of other prey items in sample.
We will use a method similar to Rieman et al. (1991) to estimate the total loss of juvenile fall Chinook salmon to two different size classes (175-249 mm and ³250 mm) of smallmouth bass in two sections (above and below the Salmon River) of the Hells Canyon Reach of the Snake River:
Li j = å Nk i C i j P j
where: L i j = the loss of fall Chinook salmon in the section i in biweekly interval j,
Nk i = the number of smallmouth bass in size class k in the section i,
C i j = consumption of fall Chinook salmon in section i in biweekly interval j, and
P j= the number days in biweekly interval j. | $19,286 | 7.06% | 06/01/2012 | 05/31/2013 |
