Estimation of Fish Biomass Using Environmental DNA
Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass. We developed an eDNA method to estimate the biomass of common carp (Cyprinus carpio L.) usin...
متن کاملEvaluating a Fish Monitoring Protocol Using State-Space Hierarchical Models
Using data collected from three river reaches in Montana, we evaluated our ability to detect population trends and predict fish future fish abundance. Data were collected as part of a long-term monitoring program conducted by Montana Fish, Wildlife and Parks to primarily estimate rainbow (Oncorhynchus mykiss) and brown trout (Salmo trutta) abundance in numerous rivers across Montana. We used a ...
متن کاملEnvironmental DNA for freshwater fish monitoring: insights for conservation within a protected area
Background Many fish species have been introduced in wild ecosystems around the world to provide food or leisure, deliberately or from farm escapes. Some of those introductions have had large ecological effects. The north American native rainbow trout (Oncorhynchus mykiss Walbaum, 1792) is one of the most widely farmed fish species in the world. It was first introduced in Spain in the late 19th...
متن کاملMonitoring endangered freshwater biodiversity using environmental DNA.
Freshwater ecosystems are among the most endangered habitats on Earth, with thousands of animal species known to be threatened or already extinct. Reliable monitoring of threatened organisms is crucial for data-driven conservation actions but remains a challenge owing to nonstandardized methods that depend on practical and taxonomic expertise, which is rapidly declining. Here, we show that a di...
متن کاملMonitoring environmental effects of marine fish aquaculture
As mariculture production increases in both northern and southern Europe its conflict with other users of the marine environment, for space and other environmental services, becomes ever greater. Implications of these increases and conflicts require that careful environmental management of aquaculture practices be considered, which rely heavily on the process of monitoring. Monitoring studies f...
