(Fig. 17.2). The main north/south difference is that on the south shores of Alboran,
little tunny is less frequent; in fact in recent years, there is no landing of little tunny
declared by Morocco, with a total of 443 t during the study period that contrasts with
the 915 t declared by Spain at the north of Alborán Sea. On the other hand, plain
bonito is the fourth most important species of tuna in the south with 655 t, while in
the north of Alborán, there are no catches reported. Plain bonito is the target by
fisheries only in the South Alboran Sea (UNEP-MAP-RAC/SPA 2014)

species in the North Alboran Sea, in the open sea, are Atlantic bonito (Sarda sarda), bullet tuna
(Auxis rochei), bluefin tuna (Thunnus thynnus), and little tunny (Euthynnus alletteratus) during the
period 1985–2018. Data sources in IDAPES (2020)
