Aquaculture Monitoring Standard (PDF 138 KB)

Introduction

This Aquaculture Monitoring Standard (monitoring standard) will support the monitoring and sampling requirements of the Aquaculture Activities Regulations (AAR) under the Fisheries Act. This document provides the necessary level of detail to enable the owner or operator of an aquacul-ture facility to produce to the greatest extent possible, consistent and high quality data to support the implementation of the AAR.

This monitoring standard will be amended (in consultation with provinces) from time to time.

Definitions

Containment array
means an assembly of interconnected cages used to cultivate fish.
Marine worms
mean aggregates of opportunistic polychaetes that colonize organically enriched substrates
Reference station
means a sampling station chosen to represent a background or natural state. Reference stations may be chosen as discrete sampling locations or contained along a transect representing a traditional “gradient” to “background” approach.
Sampling station
means the location where recording is carried out and any samples are collected.
Soft bottom
site means, further to definition in AAR, a site where acceptable samples can be taken from the benthic substrate based on the grab acceptability criteria and sampler options re-lated to oceanographic conditions and substrate type or classified as soft bottom based on pro-vincial criteria.
Transect
means a directional line, along which sampling stations are established or visual observations are made.
