    Description: Los giros ciclónicos son lugares donde se concentra una gran cantidad de partículas suspendidas en la columna de agua, entre ellas el fitoplancton que es una parte importante de la cadena trófica. En el sur del golfo de México (GoM) la mayoría de la flota pesquera de altamar suele moverse entre sitios conocidos, debido a la concentración de organismos. Algunos de estos sitios se encuentran ubicados en el área de influencia del giro ciclónico de la bahía de Campeche. Usando datos de satélite de las corrientes geostróficas, se analizó la variación geográfica de la posición del giro de Campeche, con respecto a las zonas de pesca, para los meses de noviembre a febrero del 2014 al 2017. En el golfo de México el pez sierra (Scomberomorus maculatus o Spanish mackerel), que por su captura se localiza en el treceavo lugar a nivel nacional en México, reporta la mayor captura en la zona de Campeche. Esta especie, al igual que otros organismos marinos del sur del GoM, aprovechan de manera indirecta los nutrientes aportados por el giro de Campeche, el cual se desplaza de acuerdo con las condiciones oceánicas y atmosféricas de mesoescala, de ahí la importancia de conocer su ubicación para las pesquerías, tanto de altamar como artesanales. Por tal motivo en este trabajo se pretende describir la relación que existe entre el giro de Campeche, el cual aporta una gran cantidad de nutrientes y la captura del pez sierra.
    Description: Cyclonic gyres are places where a large amount of suspended particles are concentrated, among them the phytoplankton, an important piece of the trophic chain. In the southern Gulf of Mexico (GoM) most of the fishing fleet usually goes to well-known sites. Those are sites where the organisms use to concentrate. Some of these sites are located in the area of influence of the cyclonic gyre of the Bay of Campeche. Using satellite data of the geostrophic currents, we analyzed the geographical variation of the position of the Campeche gyre, with respect to the fishing areas, for the months of November to February 2014 to 2017. In the Gulf of Mexico, the sawfish (Scomberomorus maculatus or Spanish mackerel), which due to its capture is located in the thirteenth place at a national level in Mexico, reports the highest capture in the Campeche area. This species, as well as other marine organisms from the south of GoM, indirectly take advantage of the nutrients provided by the Campeche gyre, which moves according to the oceanic and atmospheric conditions of the mesoscale, hence the importance of knowing its location for fisheries, both offshore and artisanal. For this reason, this paper aims to describe the relationship between the Campeche gyre, which provides a large amount of nutrients, and the capture of sawfish.

    Description: Beach surface temperature is recorded every morning between 7h30 and 8h00 at each coastal station. On figure 2, 3, 4 and 5 it has been plotted daily variation and mean variation computed on 7, 15 and 30 days basis of sea surface temperature. However it seems that variations of dynamic height anomaly are reflecting more accurately the stages of the coastal upwelling than the sea surface temperature.

    Description: The fishing in 1982 has been oriented towards Sardinella aurita stock, which becomes the target species with 11.200 tons over 21.300 tons, taking the place of Sardinella maderensis, which reaches only 4,800 tons. Thehigh abundance of this species explains the decrease of fishing effort.
