The inland fisheries data collection is part of the more comprehensive data gathering carried out on an annual basis by the Fisheries Committee (COFI) of the Trade and Agriculture Directorate (TAD) from OECD members and participating non-OECD economies.

Data on marine landings, aquaculture production, inland fisheries catch, fleet, employment, total allowable catch (TAC) and fisheries support estimate (FSE) are collected from Fisheries Ministries, National Statistics Offices and other institutions designated as an official data source. The surveys used for this exercise are the OECD Fisheries questionnaires.

Inland fisheries include catches of fish, crustaceans, molluscs and other aquatic invertebrates (and animals), residues and seaweeds in lakes, rivers, ponds, inland canals and other land-locked water bodies.

For the purpose of this questionnaire the boundary between inland and marine areas at the river mouth is left to the discretion of the national authority.

Production from aquaculture installations should not be reported on this form. However, catches from fisheries that are managed by stocking should be included.

The methodological reference document for fisheries and aquaculture statistics is the CWP Handbook of Fishery Statistics.

Unit of measure used

Data are collected in tonnes and national currency at current values.

For analytical purposes and data comparisons, value data are converted and published also in US dollars.

Exchange rates are average yearly spot rates, taken from the dataset OECD Economic Outlook: Statistics and Projections.

Data reported in this dataset are expressed in tonnes, in units of national currency and in US dollars.

Data are recorded on a landed weight basis, i.e. the mass (or weight) of a product at the time of landing, regardless of the state in which is landed (i.e. whole, gutted, filleted, meal, etc.). For exceptions, please see the individual notes.

Power code

Value data are expressed in units of local currency and in units of USD, quantity data are expressed in tonnes.

Therefore the data power code is zero.

Periodicity

The data provided by countries and disseminated by OECD are annual data.

The annual time unit normally used in fisheries statistics is the calendar or civil year, i.e. the period between 1 January and 31 December. For exceptions, please see the individual notes.

Statistical population

The statistical population is the set of countries participating in the work of the COFI, i.e. OECD members, excluding landlocked countries, with some exceptions (Czech Republic and Slovakia are included, Israel is not).

The group includes also the following partner countries: Argentina, China, Chinese Taipei, Colombia, Costa Rica, Indonesia, Peru, Philippines, Russian Federation and Thailand.

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.

Classification(s) used

Species are classified according to the ASFIS list, which includes more than 12 000 species items selected according to their interest or relation to fisheries and aquaculture.

For each species item stored in a record, several descriptors are available, including the 3-alpha code identifier. The 3-alpha identifier is a unique code made of three letters that is widely used for the exchange of data with national correspondents and among fishery agencies.

FAO is the depository agency for the 3-alpha codes. Requests for information and for the allocation of a 3-alpha code to new species should be addressed to FAO.

Standard ISO 3-alpha codes are used for countries and currencies.
