 Statistics on social and economic aspects of fisheries are required as part of an ecosystem approach. These data are discussed in section on social and economic fisheries statistics. More

 Documentation that fisheries impact is within sustainable limits is based on fisheries statistics supplemented with and analysis of these data normally summarized in the form of indicators. Such indicators are often related to reference points that have been agreed as... More

 Vessel tonnage In international law, as well as in practice, two measurements of tonnage of ships have existed side by side: Gross Registered Tonnage (GRT) defined by the Oslo Convention (1947), and Gross Tonnage (GT) defined by the London Convention (1969).... More

 Vessel length The most frequently used and preferred measure of the length of a fishing vessel is length overall (LOA) which refers to the maximum length of a vessel from the two points on the hull most distant from each other,... More

 Other measures of the length of vessels are: Waterline length (LWL) which refers to the length of the designed waterline of the vessel. This measure is used in determining certain properties of a vessel for example, the water displacement; Length... More

 Data collection Data on fishery fleet are collected by means of the statistical questionnaire FISHSTAT FF. Form FF1 is used for the collection of data on decked vessels, whereas form FF2 is intended for undecked vessels for which the most important... More

 Fishery production core variables The core variables identified for capture fisheries are restricted to only two items as they are the most widely available. The core variables to be collected are: Gross value of landings Employment More

 Gross value of landings The gross value of the landings is normally collected together with landing statistics (e.g. from fish auctions or from sales slips). In order to establish the link to the catch statistics (refer catch and landings) these data... More

 Employment Employment in fisheries should be collected in sex-disaggregated form. A further note should be made that the term fisher (refer also ILO-2012) should not only include those operating from fishing vessels but also those fishers operating land-based fishing gears... More
