Maps of Adipose Marked Releases Preliminary Data for 2000

The following maps depict preliminary data for releases of hatchery reared salmon during calendar year 2000 that were mass marked with an adipose fin clip. These data were compiled at the request of the Northwest Power Planning Council, who wanted to know how much progress had been made toward marking hatchery fish so that they would be recognizable in a selective fishery. Initial Data were compiled during Spring, 2001, and then revised in August 2001. Official release data are not yet available from all agencies. Therefore, these figures should be considered preliminary and changes or corrections may occur. Fish may have been marked for purposes other than to facilitate selective fisheries, and some groups were intentionally not marked for specific reasons.

Fin clipping data are not part of the standard StreamNet database. StreamNet coordinated development of these maps at the request of the Power Planning Council because the Regional Mark Information System's new database version that will access this information had not been completed and formally adopted, and release data for calendar year 2000 had not been completed and submitted to RMIS by all agencies at the time of the request. Also, RMIS staff was short due to vacation leave, so StreamNet undertook compilation of the information.
