By Tammy C. Norgard, Graham E. Gillespie and Michelle I. Bigg
Abstract
This document evaluates the assessment and management frameworks utilized by the BC Ministry of Agriculture (BC MoA) for the commercial harvest of wild Pacific Oyster (Crassostrea gigas) in B.C. and proposes an assessment protocol for use by Fisheries and Oceans Canada (DFO) and Industry to guide DFOs management and regulation of the fishery which was delegated in 2012. The primary results of the study include the recommendation to utilize a stratified random sampling survey design on high density discrete Pacific Oyster beds using a square quadrat size of 75 cm x 75 cm or greater. The recommended sampling intensity is 10 quadrats per hectare with a minimum sample size of 5 quadrats per stratum.
