    Parámetros meteorológicos, represamiento fluvial y huracanes. Variaciones en la hidrología del golfo de Batabanó, Cuba. (2020)

    Description: The Gulf of Batabanó (GB), is the region of the Cuban marine platform of greater extension and fishing importance. Habitat effects of marine species have been reported as a consequence of natural and anthropic factors. The objective was to determine significant spatio-temporal variations in the hydrology of GB in different periods and environmental situations. For this, the variability of rainfall and air temperature was analyzed in 1975-1995 and 1996-2015 periods of low and high cyclonic activity, the thermohaline characteristics of the GB before (1959-1970) and after (2006-2016) the river damming, and the effect of two hurricanes almost simultaneous in 2008 (“Gustav” and “Ike”). Significant differences in the interannual variability of meteorological parameters between the north and south of the GB corresponded to local characteristics, and changes occurred in the distribution of the months of maximum rainfall. The perennial impact of the damming, coupled with temporary precipitation deficits in spring, summer and winter, caused thermohaline increases in 2006-2016, with an increase of 0.7 °C in water temperature and 2.3 in average salinity of the GB, with respect to 1959-1970. Salinity showed an increase in the distribution of hypersaline values, and an average 〉 36 in months of high rainfall, with a general average of 35.4 in 1959 -1970 and 37.7 in 2006-2016, this suggests that damming has been a major factor in the increase in salinity. The thermohaline impact in the GB of two hurricanes in 2008 was restored in the short term, with greater inertia in turbidity.

    Distribución espacial de la pesquería de camarón (Farfantepenaeus notialis) en el Golfo de Ana María, aplicando Sistema de Información Geográfica. (2013)

    Publication Date: 2021-05-19
    Description: Se representa la distribución del esfuerzo y rendimiento pesquero en la pesca de camarón durante el periodo de 2003 – 2005 para el Golfo de Ana María aplicando Sistema de Información Geográfica. Las salidas espaciales en los mapas obtenidos permitieron mostrar que la región de mayor esfuerzo pesquero fue la zona de Manuel Gómez, de empresas de Cienfuegos (EPICIEN), y las cuadrículas pertenecientes a la empresa de Santa Cruz del Sur (EPISUR). Los máximos de rendimiento pesquero reflejados espacialmente, pertenecen a la sub-zona Este de Manatí, al noreste de las cuadrículas de EPISUR y las sub-zonas de Manuel Gómez y Palomo. La representación gráfica de los resultados muestra que no existe una correspondencia entre el esfuerzo y la captura por unidad de esfuerzo (CPUE) obtenida por las empresas durante los tres años analizados. El programa Surfer (9.8) constituye una herramienta eficiente en la disponibilidad rápida del resultado. Además, proporciona elementos para establecer medidas de manejo espacio-temporal, por estar basado en la capacidad para almacenar y expresar los resultados con representación espacial.
    Description: The distribution of fishing effort and yield in shrimp fishery during the period 2003 - 2005 for the Gulf of Ana Maria is represented in this work applying Geographic Information System. The spatial outputs in the obtained maps allowed showing that the region of greatest effort was that of Manuel Gomez, belonging to Cienfuegos fishing companies (EPICIEN), and the grids corresponding to Santa Cruz del Sur company (EPISUR). The spatially reflected maximum fishing yields belong to the sub-area east of Manati, northeast of EPISUR grids and Manuel Gomez and Palomo sub-zones. The graphical representation of results shows that there is no consistency between the fishing effort and catch per effort unit (CPEU) by these companies during the three years analyzed. Surfer 9.8 software is an efficient tool in the rapid availability of results. It also provides elements for establishing spatial-temporal management measures, based on its ability to store and express results with spatial representation
