EU data collection framework (DCF) obligates member states to produce detailed information on national fisheries. This includes the collection of biological, economical and statistical data on fisheries and aquaculture sector. The information is used for e.g. research purposes and scientific advice.
The biological information in DCF includes:
- Biological variables of fish stocks e.g. length, age, growth and maturity in economically important species. Sampling of commercial catch.
- Research survey BIAS (echosounding and experimental trawling of Baltic herring and sprat)
- Monitoring of salmon in the Rivers Simojoki, Tornionjoki, Tenojoki and Näätämöjoki (abundance of migrating adults, parrs and smolts, fisheries surveys)
- Eel monitoring (stock status in the Rivers Kokemäenjoki and Kymijoki, and coastal areas)
- Monitoring the abundance of sea trout parrs by electrofishing in River Isojoki, Ingarskilanjoki and Mustajoki
- The development and maintenance of databases (storing and verification of sample information, stock estimates and EU data calls)

Economic and statistical data collection
In economic and statistical data collection, information on the production, operation, employment and economic development of fisheries (fishing fleet), aquaculture, and fish processing business is collected annually. The economic and statistical part of DCF includes statistics, data delivery ja reporting of the following divisions:
- Commercial fisheries data on capacity, effort and landings (including bycatch data)
- Economic and social data for fisheries
- Economic and social data for aquaculture
- Economic and social data for fish processing
- Recreational fisheries catch
- Data base development concerning previous divisions
Implementation of DCF in Finland is coordinated by separate coordination project inside Finnish DCF program. International cooperation is conducted mainly by ICES, Regional coordination Group RCG Baltic and RCG NANSEA, PGECON and STECF. At EU level DCF is coordinated by Joint Research Centre (JRC ).
The DCF information is delivered to end users (Commission, RCG:s, ICES) via data calls. In addition, several national reports and official statistics are produced, and the ecosystem effects of fisheries are estimated by using environmental indicators based on biological and socioeconomic information.
Finnish researchers and experts take part to several EU and ICES expert and working groups where the contents of DCF and the rules for the application of the databases are defined, and where the data are analyzed. The national programme in Finland fulfills the EU requirements for DCF.
