Population structure, effort and dye yielding of the snail Plicopurpura pansa (Gould, 1853) in the Mexican Pacific

Abstract

Introducción El caracol púrpura o del tinte Plicopurpura pansa (Gould, 1853; Sinónimo: Purpura pansa), es una especie conspicua de la zona intermareal del Pacífico tropical oriental (Keen, 1971). Los caracoles se encuentran comúnmente fijos a sustratos rocosos expuestos al oleaje en la zona intermareal. Su máxima

Demografía del caracol Plicopurpura pansa (Neotaenioglossa: Muricidae) y constitución de la comunidad malacológica asociada en Guerrero, México

“…Lo hallado en este trabajo en cuanto al reclutamiento coincide con lo observado por Michel-Morfín et al (2000) para Jalisco y Enciso et al (1998) para Sinaloa. Por otra parte Álvarez (1989), menciona que la aparición de los reclutas en Michoacán fue en agosto, además de que existen reclutamientos extratemporales.…”

Density, Sex Ratio, Size, Weight, and Recruitment of <i>Plicopurpura pansa</i> (Gastropoda: Muricidae) in Costa Chica, Guerrero, México

“…Because of the inappropriate management of the purple snail, its population status was severely affected, this created biological, ecological, and social problems that were analyzed from studies like the ones based on analysis of population structure and on reproductive aspects, among those of Hernández and Acevedo [9], Acevedo et al [10], Álvarez [11], León [4], Acevedo et al [12], Castillo-Rodríguez and Amezcua-Linares [13], Acevedo and Escalante [14], Holguín [15], Ramos-Cruz [16], Reyes [17], Flores [18], Acevedo et al [19], Enciso et al [20], Michel [21], Michel-Morfin et al [22], Michel-Morfín et al [23], Ramírez-Rodríguez and Naegel [24], García et al [25], Michel-Morfin et al [26].…”

Estimation of the Abundance and Population Structure of the Purple Snail Plicopurpura pansa (Gould, 1853) Comparing Two Methods

“…The linear transects has been the most commonly used method in previous studies among the different groups of investigators, to determine the relative density of the species [1,[7][8][9][10][11][12], however, some other different methods have also been applied [13][14][15][16][17][18]. There is a possibility that some of the organisms stayed out of our reach while we made our sample, therefore this method might sub estimate the abundant population.…”
