Resumen

MUJICA, Armando; NAVA, María Luisa  y  ARAYA, Andrea. Larvae of Sergestes arcticus Kroyer, 1855, Neotrypaea uncinata (H. Milne-Edwards, 1837), and Munida gregaria (Fabricius, 1793) between Seno Reloncaví and Boca del Guafo, southern Chile. Lat. Am. J. Aquat. Res. [online]. 2011, vol.39, n.1, pp.33-42. ISSN 0718-560X.

The distribution of developmental stages of Sergestes arcticus, Neotrypaea uncinata and Munida gregaria larvae caught between Seno Reloncaví and Boca del Guafo in November 2004 was analyzed. Three oceanographic zones were distinguished according to records showing the degree of participation of continental and oceanic waters. Significant differences were determined between larval distribution and development stages for these species with respect to oceanographic characteristics; said differences might be related to the spawning sites and the habitat of the spawning stock in the study area.
