Rapids Student Data Collection
The name given to an effort to teach students about fisheries technician work and get data collected on issues important to fishermen at the same time. This is Rapids Research Center at it’s best.
This project has been an extension of Rapids video fishwheel monitoring since 2001. During the first years, video project operation and data provided much of the focus of the students. Since then the project has taken on it's own valuable data collection by taking sex, length, girth, weight, Ichthyophonus, and fall chum ID data on approximately 1000 subsistence Chinook, 1000 chum salmon plus whitefish species info each year. Major funding for the first five years of operation was provided by the USFWS Office of Subsistence Management. Much equipment and resources available through the funding of the video project by the Yukon River Panel, and donations and loans from private individuals, YRDFA, local schools and tribal organizations have also kept this project alive. The project lost it’s major funding in 2006, however the Yukon River Drainage Fisheries Association funded a reduced data collection effort that was very successful in 2006. In 2007 Yukon River Panel funding through an ADF&G/YRDFA project plus Rapid Research Center funds again kept the project alive. The project is currently in need of a higher, more secure level of support in order to fairly compensate the student techs who work each summer. Thank you OSM, YRDFA, ADF&G and Yukon River Panel.

Meta Cercarial Trematode
In 2003 this project identified a white spot that was found on some chum and many whitefish hearts simply as “surface white spots” in order to distinguish them from Ichthyophonus (ICH) spores which they were externally similar to. These spots were often mistaken as ICH by many fishermen and the fish sometimes discarded for this reason. While this important information was voiced around the local area and on YRDFA teleconferences it was not until 2005 that the spots were finally identified by name by Joe Sullivan (YRDFA) and Simon Jones (DFO Canada) as meta cercarial trematode, a fluke and harmless to both humans and the fish. As you can see in the video the fluke does not penetrate into the meat of the heart as does ICH but lies just under a thin membrane. Below a picture on left and video on right.
