Historical fish survey datasets from productive aquatic ecosystems in Lithuania

Fish abundance, biomass and sizes were surveyed by national Lithuanian agencies using a range of gillnets and trawls during 1950-1980s. For each survey fish abundances, sizes and biomasses were recorded and stored in archival journals, currently available at Nature Research Centre (Lithuania). In this dataset, the archival journals were digitized and data was standardized using available information on gear types and fishing effort.
