title: Fish scale-loss caused by simulated hydraulic shear stress

description: Riverine fishes found within streams impacted by hydropower also often pass through hydropower turbines during annual downstream migrations. During turbine passage events, fish may experience a suite of stressors including rapid pressure changes, impacts from turbine blades, and exposure to hydraulic shear. Scale-loss is often observed in fish collected below dams and hydraulic shear is the most likely cause of this trauma. While exposure to shear may cause other injuries, scale-loss appears to be the most common non-lethal injury observed to date. We sought to quantify how hydraulic shear may cause scale-loss in rainbow trout, gizzard shad, and hybrid striped bass by precisely controlling the exposure level (velocity) and duration (seconds) of a water jet. We targeted the same area for all three species found between the operculum and dorsal fin on the left, lateral surface. Exposure velocities ranged from 0 (controls) to 11.0 meters/second but fish were only exposed to the water jet for 1.5 seconds. A 0.2 milligram/milliliter solution of fluorescein was used to stain the areas of scale-loss by submerging each fish in this solution for at least 6 minutes. Fluorescein was used because it interacts with epithelial tissue that has been damaged and it fluoresces under ultraviolet lighting. Fish were photographed under short- and longwave ultraviolet lighting in a dark chamber to capture fluorescence. Fish photographs were analyzed using ImageJ and the proportion of descaled area was estimated for each fish within a 35 by 35-millimeter square. In general, these data highlight how exposure to hydraulic shear may lead to significant levels of descaling in riverine fishes.

title: Fish injury and mortality caused by simulated impacts from turbine blades

description: Riverine fishes impacted by hydroelectric dams often pass through hydropower turbines during annual downstream migrations. During turbine passage, fish may experience a suite of stressors including rapid pressure changes, exposure to hydraulic shear, and impacts from turbine blades or collisions with stationary structures. To better understand the effects of blade strike impact on rates of fish injury and mortality, we conducted controlled experiments on nine species of riverine fishes. Two main treatment effects were investigated relative to 1) aspects of the turbine blade and 2) changes relative to where the strike impacted the fish itself. Blade impact velocity (meters per second) ranged from 4.7 to 13.6 and blade leading edge thicknesses of 19, 26, 52, or 76 millimeters were also used in these experiments. Impacts with the fish could vary by location (head, mid-body, or tail), orientation (dorsal, lateral, or ventral surfaces), and angle of strike (45, 90, or 135°). Exact treatment conditions varied by groups of 20 to 25 individuals and also included 3 to 5 control fish. Anesthetized fish (including controls) were placed in the simulated blade strike apparatus, struck (if a treatment fish), tagged for identification, and were observed for one-hour post-strike to assess survival. Following observation, all fish were euthanized to perform detailed external and internal examinations for injuries. Other characteristics of the fish reported in these data are standard or total length (centimeters), wet mass (grams), and sex (for some species). Simulated impact testing was successfully performed on more than 2500 individual fish nine species (gizzard shad, rainbow trout, hybrid striped bass, bluegill sunfish, American eel, American paddlefish, brook trout, American shad, and blueback herring) over a five-year period. In general, these data have confirmed impacts may be severely injurious and cause direct mortality if riverine fishes are exposed to strikes from hydropower turbine blades.
