          Abstract

          Se analiza la distribución de los estados de desarrollo de las larvas de Sergestes arcticus, Neotrypaea uncinata y Munida gregaria, capturadas entre el seno Reloncaví y la Boca del Guafo, durante noviembre de 2004. Se distinguieron tres zonas oceanógraficas, de acuerdo a los antecedentes relacionados con el grado de participación de aguas continentales y oceánicas. La distribución de las larvas de estas especies y sus estados de desarrollo, permitieron establecer diferencias significativas entre ellas respecto de las características oceanógraficas, lo que estaría relacionado con los lugares de desove y habitat de las poblaciones desovantes en el área de estudio.

          Translated abstract

          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.
