Temporal development of the Lusitanina/Boreal species ratio (1965-2016), May. 2020

This metadata describes the ICES data on the temporal development of the Lusitanina/Boreal species ratio in the periode from 1965 to 2016.

Key message: The ratio between the number of Lusitanian (warm-favouring) and Boreal (cool-favouring) species are significantly increasing in 6 of the Northern division whereas there is no significant changes in all the (Southern) other divisions.

Blue dots indicates L/A ratios below 1

Yellow dots indicates L/B ratios >=1 and <2

Red dots indicates L/B ratios >=2

The dataset is derived from the ICES data portal 'DATRAS' (the Database of Trawl Surweys). DATRAS is an online database of trawl surveys with access to standard data products. DATRAS stores data collected primarily from bottom trawl fish surveys coordinated by ICES expert groups. The survey data are covering the Baltic Sea, Skagerrak, Kattegat, North Sea, English Channel, Celtic Sea, Irish Sea, Bay of Biscay and the eastern Atlantic from the Shetlands to Gibraltar. At present, there are more than 45 years of continuous time series data in DATRAS, and survey data are continuously updated by national institutions.

The dataset has been used in the EEA Indicator "Changes in fish distribution in European seas" https://www.eea.europa.eu/data-and-maps/indicators/fish-distribution-shifts/assessment-1.

The dataset has been used for this static map: https://www.eea.europa.eu/data-and-maps/figures/temporal-development-of-the-lusitanina included in the "Marine messages II - Navigating the course towards clean, healthy and productive seas through implementation of an ecosystem‑based approach" (EEA Report No 17/2019) https://www.eea.europa.eu/publications/marine-messages-2

Explanation: See the referenced specification

Statement: The dataset is based on the ICES statistical rectangles. ICES statistical rectangles provide a grid covering the area between 36°N and 85°30'N and 44°W and 68°30'E. The dataset describes the center coordinate of the rectangles. More information about the ICES statistical rectangles can be accessed here:

https://www.ices.dk/data/maps/Pages/ICES-statistical-rectangles.aspx

The dataset is extracted from DATRAS which is an online database of trawl surveys with access to standard data products. DATRAS (the Database of Trawl Surveys) has been developed to collate and document the survey data, assure data quality, standardise data formats and calculations, and ease data handling and availability. With the possibility for instant remote access, the data from DATRAS are used for stock assessments and fish community studies by the ICES community and public users. More information about DATRAS can be accessed here: https://www.ices.dk/data/data-portals/Pages/DATRAS.aspx.
