Extraction of fish - Sprat extraction (landings) HOLAS 3
The dataset contains the extraction of one of the target species, sprat, for the period 2016-2020. The extraction of sprat data set is based on "Fish extraction - commercial fisheries HOLAS 3". Further information about how this dataset was collected and extracted can be found at: https://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/a0104cfd-d237-459b-84f8-8e9e21d2df9b
Reported per ICES Rectangles, Russian data extracted from ICES annual reports, reported per ICES sub-divisions. Values are redistributed with fishing effort data c-squares (all gears) 2016-2021. Effort values missing from Russia and sub-basin average values given. Extraction of fish species (landings) per ICES c-squares, average of 2016-2020. Landings calculated per km2. Tons/km2 calculated for each species. Log-transformed and normalized.

Data source:
The extraction of herring data set is based on "Fish extraction - commercial fisheries (HOLAS 3)". Further information about how this dataset was collected, the area it covers and how the data was extracted can be found at: https://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/a0104cfd-d237-459b-84f8-8e9e21d2df9b
Spatial extent:
Reported per ICES Rectangles, Russian data extracted from ICES annual reports, reported per ICES sub-divisions. Values are redistributed with fishing effort data c-squares (all gears) 2016-2021. Effort values missing from Russia and sub-basin average values given.
Data processing:
Extraction of fish species (landings) per ICES c-squares, average of 2016-2021. Landings calculated per km2. Aggregation was calculated in Tons/km2 for each species. Log-transformed and normalized.
Data quality:
The commercial landings data is obtained from one source, but there may be gaps or mistakes in the reporting of the landings data.
Attribute information:
Final normalised pressure value (0-1)
Spatial coverage:
Entire Baltic Sea.
Spatial resolution:
Original data reported in ICES statistical rectangles (commercial landings) and ICES c-squares (redistribution). Here 1 km x 1 km grid.
