Relaciones morfométricas de Pinctada mazatlanica (Bivalvia: Pteriidae) en Puntarenas, Costa Rica

Abstract

Se trabajó con 229 especímenes de ostra perlera (Pinctada mazatlanica), recolectados por medio de buceo scuba en Isla Pájaros, Golfo de Nicoya, Costa Rica, entre abril y agosto de 1993. A cada individuo se midió longitud total, diámetro, altura y peso con una precisión de 0.01 mm y 0.05 g respectivamente. La altura máxima fue de 147.00 mm y la mínima de 21.4 mm. Las relaciones altura-peso y altura- diámetro se rigen por las ecuaciones A=O.1904 Pt+52.6354 y A=2.547 Di+ 12.5734. El crecimiento de esta especie es de tipo isométrico para la relación longitud-altura y de tipo alométrico para el resto de las variables (t-student, p

Pearl oysters (Pinctada mazatlanica) were collected by SCUBA and skin diving in a unexploited bed off Pájaros Island, Golfo de Nicoya, Costa Rica (n=229), from April to August 1993. Shell height was 21.4-147 mm. The relationships shell height: weight, and shell height: width were: A=0.1904 Pt+ 52.6354 and A=2.5734, respectively. The relationship between shell length and height was isometric, whereas the other relationships indicate allometric growth.
