Data Characteristics Data Characteristics Periodicity PeriodicityThe annual period used is the calendar year (1 January-31 December), with the exceptions of some countries for which a split-year is used. Split-year data are shown under the calendar year in which the split-year ends.
Unit of measure used Unit of measure usedCatches of fish, crustaceans and molluscs are expressed in live weight, that is the nominal weight of the aquatic organisms at the time of capture. The harvest of aquatic plants is given in wet weight. Data are given in tonnes (=1000 kg).
Population & Scope Population & Scope Statistical population Statistical populationThe statistical population is the group of OECD members, plus some partner countries (non OECD members).
In order to facilitate analysis and comparisons over time, historical data for OECD members have been provided over as long a period as possible, often even before a country became a member of the Organisation.
Information on the membership dates of all OECD countries can be found at OECD Ratification Dates.
Concepts & Classifications Concepts & Classifications Classification(s) used Classification(s) usedFish, crustaceans, molluscs and all other aquatic organisms included in the database have been classified according to approximately 300 commercial species items, further arranged within the 50 groups of species constituting the nine divisions of the FAO International Standard Statistical Classification of Aquatic Animals and Plants (ISSCAAP). The taxonomic code descriptors are taken from the "ASFIS list of species for fishery statistics purposes".
Standard ISO 3-alpha codes are used for countries and currencies.
Key statistical concept Key statistical conceptData relate to nominal catch of fish, crustaceans and molluscs, the production of other aquatic animals, residues and plants and catches of aquatic mammals, taken for commercial, industrial, recreational and subsistence purposes from inland waters. The harvest from mariculture, aquaculture and other kinds of fish farming is excluded. Data include all quantities caught and landed for both food and feed purposes but exclude discards.
The methodological reference document for fisheries and aquaculture statistics is the CWP Handbook of Fishery Statistics.
Other Aspects Other Aspects Quality comments Quality commentsSeveral countries still report their catches by large groups of species. In these circumstances the catch data presented by individual species items are likely to be underestimated. Therefore, when examining the statistics for a particular species, it should be noted that an unknown proportion of the catches for that species might have been reported by the national office under the generic, family or order name of the species, or even more roughly as "fishes not identified". Consequently, species item totals frequently underestimate the real catch of the individual species.
Where necessary, any data published in previous releases of this dataset have been revised. Where the figures in the current release differ from those previously published, the amended data represent the most recent version. Some statistics provided to FAO by national offices, in particular those for the last year, are provisional and may be amended in future editions.
Recommended uses and limitations Recommended uses and limitationsFigures flagged with 'E' corresponds to FAO estimate from available sources of information.
