Conditions: 34 F, Cloudy, Wind: light and variable, visibility: 10 mi, patchy snow and ice on the water, and 3 inches of snow accumulation on land. At 10:00 a.m. on 8, January 2008, Washington State Department of Fish and Wildlife (WDFW) received a report from John O’laughan, a resident of the Potlatch area. Mr. O’laughan reported seeing numerous dead anchovies in Hood Canal near resident’s docks in the Potlatch area. A WDFW biologist responded to the call, finding that the fish kill extended along Hood Canal’s west shoreline for a total of 15 miles. The observations were made from shorelines and docks in that area between 1100 and 1300 on January 8th. The sites investigated were Potlatch State Park, two private residence docks, Glen Ayr Resort dock, and two shoreline locations north of Hoodsport. In all areas where the anchovies were observed, there was patchy ice and snow on the water. There were abundant feeding seagulls, and seals in these areas as well. All anchovies WDFW observed were dead, some on ice/snow, and others floating on the surface of the water. No other dead fish species were observed in this area. A total of five specimens were collected. The fish were from 15-17 cm fork length. The fish were transported to the WDFW laboratory, and examined by a pathologist for signs of disease or other clues as to the cause of this fish kill. Some of the fish exhibited marks indicating predation, and all had hemorrhaging at the bottom of the eye (Figure 1). All of the fish had empty stomachs. Preliminary results showed no signs of infection, or other health problems, but the final test results may take up to a month.

The water temperature was 8-10C. There were no indications of a spill or other release of toxic chemicals in the area of the kill. On January 9, 2008, there were no additional reports of ongoing mortality. A B Figure 1: Two of the anchovy specimen collected on January 8, 2008 in Potlatch.
