Resumen

Sandy beaches, despite of not having a high complexity of habitat, they are used as nurseries by juvenile fishes due to the availability of food. The aim of this work is to study the fish fauna at five beaches on the coast of the Gulf of Cadiz. For this purpose were surveys between December 2016 and November 2017 using a beach seine net in five samples separate 25 meter each other. The size range of the fish found was, mostly, between 2 and 6 cm. The most abundant species were Atherina presbyter, Dicentrarchus punctatus, Engraulis encrasicolus, Sardina pilchardus and Trachinotus ovatus. The abundance of the most important groups of fish is correlated with the season and the water temperature. In three of the beaches the highest values of diversity occurred in the summer season. Monitoring and conducting samplings with a larger beach seine would better determine the fish community in the area.
