Comparación de la tasa de crecimiento de <i>Penaeus vannamei</i> (Decapoda: Penaeidae) en cultivos semi-intensivos de invierno y de verano

Abstract

The growth rates of Penaeus vannamei in Sinaloa, Mexico, during winter and summer semi-intensive cultures, were compared using a linear regression model that considered age and accumulated temperatures as independent variables. In the first case, the growth curves slope differed significantly, indicating a slower growth in winter; when using accumulated temperatures there was no difference in growth rates indicating that P. vannamei at 12 g (cocktail size) may be harvested when the accumulated weekly temperature reaches 300- 350°C, depending on the initial size of the organisms in culture
