Lagrangian transport as potential transport routes of fish larvae off the National Park of Cabo Pulmo at the entrance of the Gulf of California were analyzed. CTD and zooplankton samples were collected in transects off Cabo Pulmo and oceanic adjacent areas during October, 2022. Preliminary results from satellite and in situ data showed an anticyclonic eddy in front of Cabo Pulmo. A Lagrangian particle tracking model applied at the sampling stations, where the fish larvae were collected, showed that the particles sown in the sampling stations affected by the eddy circulation were trapped by this structure, and the sampling stations closer to the coast were displaced to north trapped in a coast poleward current. It is possible that the mesoscale activity reported off Cabo Pulmo support the recruitment of most fish species close to the spawning areas.
