      <abstract xml:lang="en" contentType="abstract">Fish body shape (including shape of the swimbladder) is essential for calculating Target strength (TS) in the context of fish hydro-acoustic surveys. Correct TS data is required for unbiased abundance estimations and allows for remote target classification. The present work aims at describing the exact individual shape of small pelagic fish specimen in the Baltic Sea, which can be used in shape modelling and TS modelling. The dataset contains morphometric data for individual fish specimen (coordinates along the body and swim bladder) for Clupea harengus, Sprattus sprattus and Gasterosteus aculeatus, sampled in the Baltic Sea (ICES area 27) in 2020 - 2022.</abstract>
      <abstract xml:lang="sv" contentType="abstract">Fiskens kroppsform (inklusive formen på simblåsan) är avgörande för att beräkna målstyrkan (TS) vid hydroakustiska undersökningar av fisk. Korrekta TS-data krävs för korrekta uppskattningar av förekomsten och möjliggör fjärrklassificering av mål. Föreliggande arbete syftar till att beskriva den exakta individuella formen hos små pelagiska fiskexemplar i Östersjön, vilket kan användas i kroppsforms-modellering och TS-modellering. Datasetet innehåller morfometriska data för enskilda fiskexemplar (koordinater längs kroppen och simblåsan) för Clupea harengus, Sprattus sprattus och Gasterosteus aculeatus, provtagna i Östersjön (ICES-område 27) under 2020-2022.</abstract>
