An updated checklist of YOY fish occurrence in the shallow perimetral areas of the Mar Menor (Western Mediterranean Sea)

The Mar Menor is one of the largest coastal lagoons in the Mediterranean basin. This study provides an updated checklist of the fish species inhabiting its shallow areas as young of the year in the period 2018-2019. A total of 43 taxa in 19 families were detected. This information should be useful to establish environmental monitoring programmes, as well as the implementation of management actions.
