Research Monitoring, & Reporting Ecological Framework • The EFFM consists of three components: – New regulatory framework – Increased public involvement in decision making process – Monitoring and reporting New Fisheries Management Zones FMZ Advisory Councils Role of the Advisory Council: – advise the MNR – work with existing stewardship groups – help with public consultation Together: – Identify and prioritize issues – Examine of available information – Set goals and objectives – Development management strategies FMZ 17 Advisory Council • One of three pilot councils in Ontario • Established in 2007 • Providing input and advice to aid in the development of a Fisheries Management Strategy for the zone FMZ 17 Advisory Council • OFAH • Bait Industry • Ontario BASS • Tourism (3) Federation • First Nations (3) • Muskies Canada • Peterborough Field Naturalists • Cold Creek Flyfishers • FOCA • Ontario Chinese • Lake Association (1) Anglers Association • Academia • Anglers (3) • Stewardship Councils FMZ 17 Fisheries Management Strategy • Currently working with the FMZ 17 Advisory Council to: – Identify fisheries management objectives – Identify a suite of potential management actions • Ecosystem approach • Targeting early 2009 for broad public consultation – Implementation in 2010 Broad Scale Monitoring of Inland Lakes • For each Fisheries Management Zone (FMZ) – Describe the current and changing state of the resource – Describe the current and changing pressures on the resource – Produce a periodic report on state of the resource “What” we measure State Indicators Pressure Indicators “Fishery” species Habitat Community Exploitation Abundance Bathymetry Fish species Angling effort Size Temperature Zooplankton Age Oxygen Benthos Maturation Water clarity Contaminants Water Disease chemistry Spring water Aerial effort sampling survey Proposed Netting Method • Summer sampling • Two types of gillnets – Large mesh (North American standard) – Small mesh (Ontario standard) • Stratified random sampling – Stratify by depth – Random sites within depth strata • Overnight sets (18+ hour) Fisheries Actions Goals & • Regulations Strategies • Education • Rehabilitation FMZ • Protection Councils & • Stewardship public Adaptive • Stocking participation Management • Enforcement Cycle • Etc.
