Marine Life Protection Act (MLPA) Initiative

Fisheries Uses and Values Project

Survey Design (recreational)

To address differing values of fishing grounds between different recreational user groups, we propose to stratify the recreational fishing fleet according to user type and geographical region or access areas. An initial phase of the research will be to determine the recreational consumptive population and an appropriate classification scheme that will provide useful for stakeholders and decision makers. At a minimum the following primary user types will be assessed.

Kayak and human powered vessels
Motor powered private vessels

Possible stratification by vessel length

Commercial Passenger Fishing Vessels (including "6-packs")
Shore-based anglers
Diving

Due to the unknown size of the recreational fishing community within the SCSR, the first phase of this research will be to accurately design a sampling scheme that is representative of the identified user classes and at the same time feasible to conduct under possible time and budgetary constraints. Regarding feasibility, a classification scheme that determines 1000 interviews will need to be conducted in order for it to be statistically representative, would not be possible logistically. We raise this issue because this is what we observed when determining the sample design for the recreational fleet in the NCCSR. That said, a representative sample from each stratum will be used to estimate relative levels of importance or value for each sub-user group. Existing ancillary data sources will be explored to develop this information. This will provide much needed thematic resolution currently absent from CRFS and other estimation efforts.
