Determinar la madurez sexual en invierno de la jaiba azul callinectes sapidus en la zona norte de la provincia de El Oro

The present investigation one carries out in the North Area of the County d and The Gold in the towns of the Pto. Bolivar and Under High during the months of January to June of the 2006 with the purpose of knowing the times of sexual maturity of the females of the blue Jaiba Callinectes sapidus and their partial distribution during the monitorings. The time of sexual maturity you determines in the female ovadas according to the coloration of their ovocitos, the same ones that differed in 4 types: Orange, Coffee, Black, and Yellow. For the interpretation of the obtained data they were carried out frequency distribution analysis, lineal regression analysis and graphics of percentages. The study allowed to establish that the width and longitude of the cefalotórax don't have any relationship since with its state of sexual maturity females of small and big ovadas they were presented. The classes of widths predominant cefalotoraxicas in the Pto. Bolivar and Under High they were of the range of 8,5-9 cm. During the regression analysis lineal width-longitude of the cefalotórax of the blue Jaiba (Callinectes sàpidus) evades, in Pto Bolivar you estimates that the lineal equation was: 1,5833x + 2,4809 and a r of 0,88. In Under High the regression analysis lineal width-longitude of the cefalotórax of the blue Jaiba (Callinectes sàpidus) ovadas, you estimates that the lineal equation was: 1,5675x + 2,5368 and a r of 0,9. In Pto. Bolívar, the biggest time of female ovadas you presents during the month of January with 45,45% of female ovadas. In a same way, in Under High the biggest number of female ovadas you presents during the month of June with 57,14% followed by the month of May with 55,55%.
