Name Annual coastal subsistence fish catch by volume (t)
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 fishing trips (or events) per annum x average farm-gate price (USD per tonne)
Unit of Measure Tonnes
Purpose/Rationale To estimate the total coastal subsistence catch by volume. To monitor change in catch over time, which can indicate the health status of the coastal fishery; or to monitor effectiveness of policy to divert fishing effort from the reef.
Policy Linkages SciCoFish project (PROCfish can be used as a baseline). Fish aggregation devices (FAD). Community-based ecosystems approach to fisheries management (CEAFM). Fisheries management plans. Link to F.3.1.
