Abstract

DIAZ-IGLESIAS, Eugenio  and  BAEZ-HIDALGO, Marysabel. Relative viable fecundity in the red lobster Panulirus interruptus (Randall, 1840) in Baja California, Mexico. Hidrobiológica [online]. 2010, vol.20, n.1, pp.71-80. ISSN 0188-8897.

The fundamental objective of this work is to estimate the Relative Viable Fecundity as the number of phylosomes born alive during hatching of the spawn, per longitude of the cephalothorax per female, of Panulirus interruptus in Baja California, Mexico, under laboratory conditions, with goals for its application on the culturing of the specie. The zones of origin of the spawning females were: Bahía Todos Santos, Punta Baja and Isla de Cedros, Baja California, México. From the females between 62.0-97.2 Lc (mm), an average of 224,402 live phylosomes were obtained up to 3 days after hatching. The Relative Viable Fecundity resulted between 900.1-6,922.8 phylosomes/Lc (mm), with a mean of 2 795 phylosomes/Lc (mm). The relationship between the cephalothorax length (mm) and the number of phylosomes resulted: Phylosomes = 0.0083 Lc (mm)^3.9046; r² = 0.615. The Relative Viable Fecundity estimated for this work resulted greater than that currently reported in the literature for Jasus edwardsii.
