Maximum and minimum mean values, as well as
standard deviation of hydrological parameters were
determined to make seasonality analysis and spatial
distribution. Cuban Standardization NC.25:1999
criteria were taken into a consideration to evaluate
obtained results.
Due to that samplings are punctual and do not cover
all regions, for spatial distribution analysis, ArcGIS
(10.1) program was used. It made possible to have
graphic isolines representations of hydrological
parameters. To develop contour maps,
Kringing
methodology was used because it is one of the main
interpolation techniques (Isaaks and Srivastava, 1989;
Cressie, 1990).
Commercial fishing data of catches (t) were used as
well as cumulate raining (mm) from 1975 to 2009,
obtained from Fishing Enterprise EPIGRAN
(abbreviations from Spanish) and Meteorological
Station of Manzanillo respectively. From data series,
annual and monthly average values were calculated to
determine the seasonal and inter annual pattern in the
Gulf.
Comparison and regression analyses were performed
between surface and bottom hydrological parameters.
A simple correlation test among annual and monthly
total catches of pink shrimp and cumulate raining was
made using the program Statistica 6.0 (StatSoft, Inc.
USA).
