Data to Support Efficacy Studies of Injectable Tulathromycin for Reduction of Vertical Transmission of Renibacterium salmoninarum in Spring Chinook Salmon (Oncorhynchus tshawytscha)

Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum (Rs) occurs nearly worldwide where wild or cultured salmonid fishes are present. Control of BKD is confounded by its two modes of transmission, horizontal (fish-to-fish) and vertical (from female parent to progeny via the eggs). A highly successful BKD control strategy employed in Pacific Northwest hatcheries cu

Susceptibility of Nanophyetus salmonicola cercariae to formalin, hydrogen peroxide and seawater

The ability of formalin, PEROX-AID® (hydrogen peroxide), and seawater to kill waterborne Nanophyetus salmincola cercariae was evaluated in vitro. Newly emerged waterborne cercariae survived for extended periods in freshwater, with 50-74% survival occurring in negative control groups after 24 hr. Exposure to dilutions of formalin reduced this survival time, with 0% of cerca

Earthquake Alerts: Early and Often? Or Possibly Late?

The choice when issuing earthquake warnings is to: 1) issue alerts for weak shaking and potentially provide long warning times, but risk sending alerts for the many events that do not go on to produce damaging ground shaking, or 2) issue alerts only when ground shaking is expected to be damaging, with the tradeoff that the alert will be sent much later, reducing the
