Pêche scientifique au saumon coho dans la rivière Taku, en Colombie-Britannique

Introduction

Coho salmon enumeration using mark-recapture has been conducted on the Taku River for nearly 30 years and provides a long term index of Coho abundance into the Taku River. Tags are applied to returning adult Coho salmon below the Canada-US border and are subsequently recovered in above border Canadian fisheries which are used to generate an abundance estimate. Additionally, juvenile Coho salmon are tagged (CWTs) annually in the spring and returning adult Coho are sampled to recover juvenile tags which are used to generate smolt abundance estimates and exploitation rates on Taku River Coho.

Objectives of the Requirement

The work involves the use of gill nets to capture migrating Coho salmon, recovering a statistically significant number of tags, and to conduct biological sampling of the catch (including tag/tag scar information) on the Taku River upstream of the Canada/US border, British Columbia. The work is to be performed during the annual Coho run, which occurs from approximately late august through to mid-October.

Contract Period
