“…They are broadly similar to those reported overseas (e.g. Gilderhus et al, 1986Gilderhus et al, , 1988Vasquez et al, 2012), with the half-life being in the order of days and complete dissipation occurring within two months.…”

“…Our results suggest that the dynamic first-order kinetics model is suitable for determining the half-life and days to complete dissipation of rotenone following monitoring of individual operations (Finlayson et al, 2001Vasquez et al, 2012). However, we believe that the gamma model provides significant benefits over the first-order kinetics model.…”

“…Therefore, information about the half-life of rotenone is valuable when applying for approval to use it from consenting authorities (Dawson et al, 1991;Finlayson et al, 2014) and designing water sampling protocols (Gilderhus et al, 1986(Gilderhus et al, , 1988Finlayson et al, 2014). It is also important in determining the correct amount of rotenone to apply and for maintaining public confidence in the use of rotenone by showing that it does not persist in the environment (Finlayson et al, 2001Vasquez et al, 2012).…”

Zooplankton recovery from a whole‐lake disturbance: Examining roles of abiotic factors, biotic interactions, and traits

Community assembly following disturbance is a key process in determining the composition and function of the future community. However, replicated studies of community assembly at whole-ecosystem scales are rare. Here, we describe a series of whole-lake experiments, in which the recovery of zooplankton communities was tracked following an ecosystem-scale disturbance, that is, application of the piscicide, rotenone. Using a before-after-controlimpact design, 14 lakes in eastern Washington were studied: Seven lakes were treated with rotenone, while seven lakes acted as reference systems. Each lake was monitored up to 6 months before and 1-2 years after the rotenone treatments. Zooplankton samples and environmental measurements were collected approximately monthly from each lake. Community responses following disturbance were assessed using metrics of abundance, diversity, and community composition, as well as taxonomic group abundance. Zooplankton recovery was also assessed using species traits related to habitat, feeding mode, trophic level, body size, and life history. In addition to patterns of recovery, potential mechanisms were explored relating to abiotic conditions, biotic interactions, and traits. There were steep declines in the abundance (average across years: 99%) and diversity (average across years: 75%) of the zooplankton community following rotenone treatment. Although abundance had recovered by the second year of the study, community diversity had not fully recovered after 2 years. Communities from rotenone lakes appeared to be compositionally recovered within about 8 months following disturbance. Cyclopoid copepods were typically the first group to recover and remained dominant for a few months, whereas cladocerans recovered more slowly, typically within $6-7 months following rotenone. Calanoid copepods were not fully recovered 2 years after rotenone treatment. Traits related to body size and feeding mode were associated with the zooplankton communities following rotenone treatment. We failed to observe significant spatial synchrony in recovery patterns of zooplankton across lakes, though we did observe significant synchrony of zooplankton taxonomic groups within

In September 2006, Diamond Lake (OR, USA) was treated by the Oregon Department of Fish and Wildlife with a mixture of powdered and liquid rotenone in the successful eradication of invasive tui chub Gila bicolor. During treatment, the lake was in the middle of a phytoplankton (including cyanobacteria Anabaena sp.) bloom, resulting in an elevated pH of 9.7. Dissipation of rotenone and its major metabolite rotenolone from water, sediment, and macrophytes was monitored. Rotenone dissipated quickly from Diamond Lake water; approximately 75% was gone within 2 d, and the average half-life (t½) value, estimated by using first-order kinetics, was 4.5 d. Rotenolone persisted longer (>46 d) with a short-term t½ value of 16.2 d. Neither compound was found in groundwater, sediments, or macrophytes. The dissipation of rotenone and rotenolone appeared to occur in 2 stages, which was possibly the result of a release of both compounds from decaying phytoplankton following their initial dissipation. Fisheries managers applying rotenone for fish eradication in lentic environments should consider the following to maximize efficacy and regulatory compliance: 1) treat at a minimum of twice the minimum dose demonstrated for complete mortality of the target species and possibly higher depending on the site's water pH and algae abundance, and 2) implement a program that closely monitors rotenone concentrations in the posttreatment management of a treated water body.
