AbstractThe North Slope of Alaska contains arctic fish populations that are important for subsistence of local human populations, and are under threat from natural resource extraction and climate change. We designed and evaluated four quantitative PCR assays for the detection of environmental DNA from five Alaskan fish species present on the North Slope of Alaska: burbot (Lota lota), arctic char (Salvelinus alpinus), Dolly Varden (Salvelinus malma), arctic grayling (Thymallus arcticus), and slimy sculpin (Cottus cognatus). All assays were designed and tested for species specificity and sensitivity, and all assays detected target species from filtered water samples collected from the field. These assays will enable efficient and economical detection and monitoring of these species in lakes and rivers. This in turn will provide managers with improved knowledge of current distributions and future range shifts associated with climate and development threats, enabling more timely management.

AbstractWe developed species-specific quantitative PCR assays for the detection of two freshwater mussel species native to the western North America, Anodonta nuttalliana and Anodonta oregonensis, from environmental DNA. These species have experienced dramatic declines over the last century, and are currently threatened in many portions of their range. Improved tools for detecting and monitoring these species are needed. Species-specificity and sensitivity of the assays was empirically tested in the lab, and both assays were also validated with field collected eDNA samples. We found that the assays we designed are species-specific, sensitive, and are effective for detecting Anodonta nuttalliana and Anodonta oregonensis from environmental DNA samples collected from streams and rivers. These assays will aid in the detection, monitoring, management, and conservation of these threatened species.

Tenacibaculum are frequently detected from fish with tenacibaculosis at aquaculture sites; however, information on the ecology of these bacteria is sparse. Quantitative-PCR assays were used to detect T. maritimum and T. dicentrarchi at commercial Atlantic salmon (Salmo salar) netpen sites throughout several tenacibaculosis outbreaks. T. dicentrarchi and T. maritimum were identified in live fish, dead fish, other organisms associated with netpens, water samples and on inanimate substrates, which indicates a ubiquitous distribution around stocked netpen sites. Before an outbreak, T. dicentrarchi was found throughout the environment and from fish, and T. maritimum was infrequently identified. During an outbreak, increases in the bacterial load in were recorded and no differences were recorded after an outbreak supporting the observed recrudescence of mouthrot. More bacteria were recorded in the summer months, with more mortality events and antibiotic treatments, indicating that seasonality may influence tenacibaculosis; however, outbreaks occurred in both seasons. Relationships were identified between fish mortalities and antimicrobial use to water quality parameters (temperature, salinity, dissolved oxygen) (p < 0.05), but with low R2 values (<0.25), other variables are also involved. Furthermore, Tenacibaculum species appear to have a ubiquitous spatial and temporal distribution around stocked netpen sites, and with the potential to induce disease in Atlantic salmon, continued research is needed.
