Indicator for Eastern Baltic cod length structure

Time series of indicator for size structure of the Eastern Baltic cod (Gadus morhua) stock in 1991-2021. The index represents length (in mm) at the 95th percentile of the length distribution (L95). The index is calculated using data from Baltic International Bottom Trawl survey in the 1st quarter. Raw data are available from International Council for Exploration of the Sea (https://www.ices.dk/data/data-portals/Pages/DATRAS.aspx)..<br>
