Salmonid angling – application to Tasman District Council Neil Deans, Fish and Game Nelson-Marlborough, 2009
Salmonid Fisheries • Provided guidance for developing methodology • Includes fisheries derived from • trout (brown, rainbow, lake and brook char) • salmon (chinook, sockeye) • No salmon in Tasman DC but criteria applicable
Personnel • Mary-Anne Baker, Trevor James, TDC • Neil Deans, FGNZ • Martin Unwin, NIWA • Kay Booth, Lindis Consulting • Peer Review • Chris Arbuckle, MAF • John Hayes, Cawthron
Method • Define River Value Categories and River Segments • Identify potential attributes • Select primary attributes • Choose indicators of primary attributes • Determine Indicator Thresholds • Apply indicators and thresholds
Method contd 7. Weight primary attributes (if appropriate) 8. Determine River Significance 9. Outline other relevant factors 10. Review and assess future requirements
Applying the Method • Attributes to reflect social, economic, environmental, cultural wellbeing • easier said than done • A key concept was the Recreational Opportunity Spectrum. • Provided rationale and context for this activity • Need for discipline in language and terminology • Wilderness/scenic attractiveness
Lucky to have good national data (NAS) • For 1150 angling waters, c. 800 rivers • Angling use data, angler perceptions • Water quality thresholds already determined • salmonids well studied • Cawthron Report 1205 for Horizons
Primary Attributes • Level of use • Origin of NZ users • Proportion of overseas use • Mean Free Distance (Angler Density)* • Anticipated catch rate • Anticipated chance of catching large fish • Water Quality • Scenic Attractiveness • Wilderness Character • Angler perceptions of River’s Importance
Data Gaps • Recent user perceptions about • the importance of the river, • scenic value • wilderness value • Overall evaluation of the fishery • Fish & Game pilot survey available • River labelling
Analysis • More robust analysis than already in Plan • Consistency with WCO and WONI outputs • Intuitively accurate • Comprehensive • Implications for management • Better understanding of where issues may arise
Gaps • Attributes not included; • Contribution to a collective value • Scarcity • Access • Future/potential value • Past value • Existence value • Relevance for management decisions
Issues • Importance of trialling in more than one region • Question of how many regions before method is ‘standardised’ for national application • Original regional analysis may need review before ‘final’ acceptance • What to do about data gaps?
