Locks and dams are possible management points to block the spread of invasive Asian carps in the United States. Infusion of carbon dioxide (CO2) into water is one deterrent strategy being considered at navigational structures to reduce upstream fish passage that would not directly interfere with lock and dam operations. The goal of this study was to determine the efficacy of CO2 as a behavioral deterrent to free-swimming fishes. Telemetered bighead carp (Hypophthalmichthys nobilis) and grass carp (Ctenopharyngodon idella) were monitored within a U-shaped pond (30.5 m long x 13.7 m wide x 1 m deep) using a two-dimensional acoustic telemetry array. Gaseous CO2 was administered to one-half of the pond at 30, 75, or...
There is growing interest in the use of carbon dioxide (CO2) as a management tool for controlling invasive fishes. However, there is limited published data on susceptibility of many commonly encountered species to elevated CO2 concentrations. Our objective was to estimate the 24-h LC50 and LC95 of four fishes (Rainbow Trout Oncorhynchus mykiss, Common Carp Cyprinus Carpio, Channel Catfish Ictalurus punctatus, and Westslope Cutthroat Trout Oncorhynchus clarkii lewisi). In the laboratory, we exposed fingerlings to a range of levels of CO2 for 24-h in unpressurized, flow-through tanks. A Bayesian hierarchical model was developed to estimate the dose response relationship for each species of fish with associated uncertainty,...
This dataset includes laboratory data collected to determine the effects of hydrogen peroxide on nitrification processes in biofilters of recirculating aquaculture systems (RAS). Data from the laboratory studies were used to inform methods used to conduct field trials in pilot- and commercial-scale RAS. Biofilter nitrification was monitored by measuring the levels of total ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen in experimental aquaria containing a small biofilter before and after hydrogen peroxide was applied to the test system. There are 4 excel workbooks associated with this data set: RASHP Range finding Trial.csv, RASHP Definitive Trial.csv, Hydrogen Peroxide Lab Studies.csv, and DO after HP...
