Area 4 Chum Enumeration Plan Evaluation

Abstract

Skeena chum are a stock of concern and understanding trends in spawning abundance play an integral role in chum assessments. This project was an evaluation of the Skeena chum escapement survey plan against the requirement to provide representative indices of spawner abundance. The previous core stock assessment chum spawner enumeration plan (English et al 2006) was reviewed and updated. The recommended surveys were completed in 2009 by experienced DFO or First Nations staff. This review makes recommendations on continuing the program with some minor changes.

Note: data from the 2009 chum escapement survey can be viewed here.
