Biological aspects of sailfin dory, Zenopsis conchifer, were studied from 839 individuals obtained from deep-sea commercial bottom trawling off southern Brazil at depths up to 526 m in 2002 and 2003. Samples included fish from 101 mm Lt and 15 g up to 640 mm Lt and 2,9 g. The sex-ratio was 50% at 150 mm Lt and between 300-350 mm Lt, with females outnumbering males in the remaining size classes. Reproductive activity seems to peak between July and August ( austral winter). Size at attainment of 50% maturity (Lt(50)) was 311 mm Lt in females. The mean length and maturity of the specimens increased with depth, suggesting that larger fish concentrate in deeper waters.

[ES] Este artÃculo es un adelanto de los resultados de la Tesis Doctoral que está realizando la autora y la que es dirigida por la Dra. Mª del Pino Palacios DÃaz, del departamento de PatologÃa animal, Producción animal, BromatologÃa y TecnologÃa de los alimentos. La finalidad del presente estudio es comprobar la viabilidad de un sistema de riego enterrado que incremente la seguridad sanitaria en el reuso de aguas depuradas para la producción de forraje en Canarias, disminuya el consumo de este recurso y facilite las operaciones de cultivo en las zonas regadas. Los datos que se presentan a continuación son los correspondientes a una fase de puesta en marcha del sistema. Ha sido financiado con una beca INNOVA dentro de un proyecto bajo convenio entre el Consejo Insular de Aguas y la Granja AgrÃcola Experimental de GC y la ULPGC.
