Growth of the purple snail Plicopurpura pansa in Baja California Sur, Mexico
To study the growth of the purple snail Plicopurpura pansa at the northern limit of its distribution, from 1999 to 2001 monthly random samples were obtained from two beaches in the southern part of the Baja California Peninsula (Mexico): one on the Gulf of California and the other on the w...

Para estimar el crecimiento del caracol de tinte Plicopurpura pansa en el límite norte de su distribución geográfica, de 1999 a 2001 se efectuaron muestreos mensuales en dos playas al sur de la Península de Baja California, una en el Golfo de California y otra en la costa oeste de la península. Además, se realizaron experimentos de marcado y recaptura, y mantenimiento de individuos bajo condiciones de laboratorio. Los valores de la ecuación de crecimiento de von Bertalanffy, estimados a partir del análisis de frecuencias de tallas, fueron K = 0.17 y L∞ = 90 mm, y concuerdan con los derivados de los experimentos de marcado, pero son menores a los calculados en lugares más al sur en la costa del Pacífico mexicano. En condiciones de laboratorio los caracoles presentaron tasas de crecimiento muy bajas. Estos resultados deberán ser considerados en la construcción de modelos para evaluar la posibilidad de explotar o cultivar el caracol de tinte.
