Determination of the degree of use of the natural resource Blue crab Callinectes sapidus based on the analysis of sizes and sexual maturity in the Ciénaga Grande of Santa Marta, Colombia

The objective of this research was to determine the degree of use of the natural resource (blue crab-Callinectes sapidus) in the Ciénaga Grande of Santa Marta (CGSM), in order to generate biological information of interest for the responsible management of the natural resource. A quantitative study was developed. Data is processed through frequency and percentage measurements for each variable (sex, shell length- Lca, shell width- Abel, maturation), The data is processed through frequency measurements and percentages for each variable, regression graphs, frequency tables to know the size structure. 2346 specimens collected, presenting 47% of the catches below the average size at maturity. In 2018 there were increases in catches with a ratio of 9:2; while in 2021 the largest Abel (9.55cm), carapace length in centimeters-Lca (5.74cm) and weight (106gr) were recorded, that they probably present a moderate risk of exploitation.
