Sub-theme Economics of Fisheries and Aquaculture: macro aspects.
Name Annual coastal subsistence fish catch by value ($US’000)
Definition Coastal fisheries are defined as fisheries that target fish, crustaceans and invertebrates that are typically associated with coastal marine and reef environments. That is, we exclude pelagic fish species. A subsistence fishery is a fishery where the catch is shared and consumed directly by the families and kin of the fishers rather than being sold.
Calculation/Formula Average coastal subsistence catch volume (t) per fishing trip (or event) x total coastal subsistence fishing trips (or events) per annum x average farm-gate price (USD per tonne)
Unit of Measure US$
Purpose/Rationale To estimate the total coastal subsistence catch by value and estimate the contribution of coastal subsistence fisheries to GDP.

Preferred Data Sources SPC creel survey
Primary Data Collection System Survey - SPC contacting national ministries and agencies
Frequency of Data Collection Country dependent for creel and market surveys (some ongoing, some never). Gillet publications have occurred twice (2009 & 2011).
Other agencies countries_ must report to: ADB / FAO publications - Fisheries Contribution to the Pacific Island Countries and Territories (written by Robert Gillet in 2009 & 2011)

Notes Pricing subsistence is a problem. Do we adopt a shadow price (i.e. price that would have been paid for fresh fish less transaction costs), the price of substitutes or use the prevailing market price?
