Compilation of Food Balance Sheets for Fish and Fishery Products: current system and future improvementsby Gabriella LaurentiStatistics and Information Service (FIPS)Fisheries and Aquaculture Policy and Economics Division
Structure of Fishery SUA’s • Fishery SUA’s are the result of the aggregation of 3 different databases which have already been consolidated, finalized and disseminated • aggregation of individual species and products (about 1700 for production and 900 items for trade) • currently conveying into 8 main groups of similar biological characteristic, each one containing up to 11 processing/product types
Population SUA’S/FBS FAOSTAT SUA’S/FBS Disposition Integration of different datasets Capture Production: 1700 species FI/FAOSTAT Production: 8 main groups Aquaculture Production: 460 species Commodities: 900 items FI/FAOSTAT Trade: up to 100 items
Items – main groups of species • Freshwater and Diadromous • Demersal • Pelagic • Marine fish nei • Crustaceans • Molluscs • Cephalopods • Other aquatic animals
Product types according to utilization • fresh, whole • frozen, whole • fresh fillets • frozen fillets • cured • canned • prepared • meals • body oils • liver oils • meals from offals
Data sources Capture/Aquaculture: • FAO Production questionnaires • National publications • Reports from Regional Organizations Commodities: • Electronic data provided by ESS • Questionnaires • National publications Classifications used: • FAO ISSCAAP for production • FAO ISSCFC for trade
FAO/FIPS statistical questionnaires for reporting fishery data
Historical outline • Until Dec. 2006 fully integrated in old FAOSTAT system • FAOSTAT2 did not satisfy FI requirements: • difficulty in handling consolidated series • severe limitations and constraints over its practical application for fishery SUA’s and FBS • partial coverage (from 1990 only) • Need to create an independent system Operational in July 2007
Substantial differences with ESS SUA’s • highly aggregated from consolidated db = no data source/history • more simplified structure without automatic trees or shares • frequent historical data revisions, due to changes in species identification and product classification
FIPS FBS System: main features • Updating and maintenance of SUA’s • Production of FBS • Preparation of different formats of output incl. those compatible with external systems (e.g. FAOSTAT feeding) • Integration within FIPS internal workflow (link with FIPS databases, sharing reference tables) • Important role of consistency checking tool between the various parts composing fishery statistics
Data standardization • Balancing of each primary and processed item • Calculation into live-weight equivalent, by using technical conversion factors
Food fish supply Total fishery production (Capture+Aquaculture) + Imports and direct landings of foreign vessels - Exports and direct landings abroad - Reduction of meal and oil - Other non-food uses - Wastage + or - Stock variations
Main problems - possible causes of errors and bias • Reliability of basic data • Subsistence fisheries and unrecorded production • Landings abroad • Foreign landings in domestic ports • Vessels using flags of convenience • Info on species composition • Technical conversion factors • Losses • Utilization • Processed commodities • Stocks
Dissemination of Fishery FBS • formerly as a Fisheries Circular • currently included in FAO Yearbook of Fishery and Aquaculture Statistics • online through FAOSTAT • tables in the State of World Fisheries and Aquaculture – consumption and utilization
Future enhancements • After HS classification change, which had a successful impact over item attribution, other modifications are in the pipeline: • split of “Freshwater and Diadromous Fish” into two separate groups • split of “Pelagic Fish” into “Large Pelagic” and “Small Pelagic” • introduction of accounts for aquatic plants • revision of nutritive factors
