Methods, standards and classifications
In response to a growing demand for high-quality and internationally-comparable statistics, FAO develops, implements and promotes methods and standards to guide national data producers in generating and using sound statistics. In particular, the Organization is committed to provide national statistical systems with internationally recognized definitions, concepts and classifications as well as methodological guidance for the production of high quality statistics related to food and agriculture.

Purpose of the Classification | |
|---|---|
Statistical Domain | Fishery and aquaculture statistics |
Purpose | For statistical purposes, particularly for reporting fishery and aquaculture production. FAO Major Fishing Areas for Statistical Purposes are arbitrary areas, the boundaries of which have been determined in consultation with international fishery agencies. The rationale of the FAO Major Fishing Areas has been that the areas should, as far as possible, coincide with the areas of competence of other fishery commissions when existing. This system facilitates comparison of data, and improves the possibilities of cooperation in statistical matters in general. |
Main Applications | To classify capture fisheries and aquaculture production by areas where the fish is caught or harvested. When establishing new regional fishery bodies, FAO Major Areas often becomes a basis to determine the scope of their jurisdiction. |
Main Users | FAO, national fishery and aquaculture statistical offices, international organizations, regional fisheries bodies. |

Criteria for Definition of Levels | The FAO Major Fishing Areas for Statistical Purposes are arbitrary areas the boundaries of which were determined in consultation with international fishery agencies on the basis of various considerations, including: the boundary of natural regions and the natural divisions of oceans and seas; the boundaries of adjacent statistical fisheries bodies that had already been established in intergovernmental conventions and treaties; existing national practices; national boundaries; the longitude and latitude grid system; the distribution of the aquatic fauna; the distribution of resources and the environmental conditions within an area. For statistical purposes, 26 major areas currently exist. These comprise: seven major inland areas covering the inland waters of the continents and 19 major marine areas covering the waters of the Atlantic, Indian, Pacific and Southern Oceans, with their adjacent seas. Until 1990, another area existed for inland area “Former USSR area”. Some FAO major marine areas are further divided into subareas, divisions and subdivisions, according to the needs of the regional fishery management bodies responsible for managing the fisheries and fishery resources of the individual FAO Major Areas. These systems of subareas, divisions and subdivisions have been successfully developed and implemented by relevant regional fishery bodies; any modifications are duly reported to CWP. | ||||||||||||||||||||

Criteria for Definition of Levels | The ISSCAAP comprises 50 groups under nine divisions. The first eight divisions are dedicated to major groups of marine and freshwater animals, the ninth division is for aquatic plants. Species are classified by these groups and divisions on the basis of their taxonomic, ecological and economic characteristics. | ||||||||||||

Purpose of the Classification | |
|---|---|
Statistical Domain | Fishery and aquaculture statistics |
Purpose | This classification is designed to cover the products derived from fish, crustaceans, molluscs, other aquatic animals and plants for which the Food and Agriculture Organization of the United Nations (FAO) collects national statistics on production and trade on a regular basis. It includes live species as well products resulting from further processing of species destined to human consumption or to other purposes including ornamental. |
Main Applications | For collection and dissemination of fisheries commodities production and trade statistics by FAO. One basic purpose of the classification system for fish and fishery products was to improve presentation of comparability of statistics of different types collected from a wide range of sources. It also serves as: a) a basis for statistical collection procedures; b) a framework for compilation and presentation of statistics; c) aggregates and elements for analyses; d) a set of elements (or building blocks) suitable for rearrangement or expansion for special studies or for special purpose classification systems. |
Main Users | Users of the FAO Fisheries commodities production and trade statistics and Fishery statistical offices. |

Scope | The ISSCFC classification is designed to cover fish, crustaceans, molluscs, other aquatic animals, plants and their based products for which FAO collects production and trade statistics on a regular basis. Products are classified according to the species and to the degree of processing. It also includes species for ornamental purposes, for culture (i.e. fingerlins, fry, etc), corals, sponges, residues, seaweeds and other algae. At present, it does not include aquatic mammals, frogs and crocodiles. Fisheries operations and services are also excluded, along with other fishery-based activities. | ||||||||||||||||||||||||||||

Statistical Domain | Fishery statistics |
Purpose | Although this classification was initially designed to improve the compilation of harmonized catch and effort data on the STATLANT B questionnaires and in fish stock assessment exercises, it has also been found very useful for fisheries technology and the training of fishers. It has been used in particular for reference in works dealing with the theory and construction of gear and for the preparation of specialized catalogues on artisanal and industrial fishing methods. |
Main Applications | Identifying the fishing technology in reporting on fishing CATCH and EFFORT; a part of basic definition of different "fisheries". |
Main Users | Fishery statistical offices, fishery scientists, MCS (management, control and surveillance) of fishing activities, fisheries technology and training fishers. |
