Sample collection occurred at 66 trawling stations located in the Italian waters of the Northern Adriatic Sea within the framework of the SoleMon project (CNR-IRBIM) between 2008 and 2023. The dataset was compiled, harmonised and published within the CNR project USEit - Using operational synergies for the study and integrated management of invasive alien species in Italy.

The hauls are planned according to a depth-stratified sampling scheme with random allocation of the positions of sampling stations within each stratum. The hauls are performed yearly between October and December during the daylight. SoleMon Handbook Version 4. July 2019. https://dcf-italia.cnr.it/rest/uploads/SOLEMON-Handbook_2019_Ver_4 Biological invasions represent today one of the greatest threats to global biodiversity, with negative impacts on human health and the economy of our country. The USEit project addresses this problem by involving a number of marine and terrestrial institutes of the National Research Council of Italy (CNR). Our main goal is to empower the scientific research on invasive species and to transform this challenge into new opportunities and new growth strategies.
