Temporal and spatial patterns on serra, Scomberomorus brasiliensis (Teleostei, Scombridae), catches from the fisheries on the Maranhão coast, Brazil.

The displacement pattern of the serra, Scomberomorus brasiliensis, in North-eastern Brazil was analyzed from landing data recorded form the fleet fishing serra. Serra fishery has two seasons: from Septemer to February (demersal species plus serra), and from March to August (almost only large amounts of serra). S. brasilienisis relative abundance increases similarly along the coast from March. but decreases first on the West coast from June. Records indicate that serra is near the coast at least until September/October in Eastern grounds. From October to March (strongest spawning season) there is no record of shoals on the coast. We concluded that the Maranhão coast is just a part of the migration circuit of S. brasilienisis that may exceed 300 nautical miles.
