Biología reproductiva del langostino y del camarón de las aguas marinas argentinas.

Abstract

Este trabajo reune información publicada e inédita sobre la biología reproductiva del camarón Artemesia longinaris (Penaeidae), el langostino Pleoticus muelleri (Solenoceridae) y el sergéstido Peisos petrunkevitchi (Sergestidae) de aguas marinas argentinas. Se caracterizan los estadios de desarrollo gonadal y diferencian, a nivel específico, los estadios larvales y postlarvales. Se indican la talla y edad de madurez sexual morfológica y fisiológica estimadas y se caracterizan los espermatozoides y espermatóforos. Se esquematiza el ciclo de vida de cada especie y se muestra el rol que desempeña la comunidad de macroalgas como área de cría para el camarón A. longinaris frente a la Provincia de Buenos Aires (Mar Argentino). This work is summarizes published and unpublished information on the reproductive biology of Argentine stiletto shrimp Artemesia longinaris (Penaeidae), Argentine red shrimp Pleoticus muelleri (Solenoceridae) and sergestid Peisos petrunkevitchi (Sergestidae) of Argentine marine waters. The gonadal developmental stages are characterized and, at specific level, larval and postlarval stages differentiated. The estimated size and age at morphological and physiological sexual maturity are indicated and spermatozoids and spermatophores characterized. The life cycle of each species is schematized and the role the macroalgae community plays as nursery ground for Argentine stiletto shrimp A. longinaris in front of the Province of Buenos Aires (Argentine Sea).
