Abstract

La crianza de animales es un fenómeno asociado a los orígenes del hombre moderno. Sin embargo, la crianza de especies marinas está relacionada con la producción intensiva en cultivo con fines comerciales. Este estudio tiene como objetivo determinar la factibilidad de crianza de Schroederichthys chilensis, la pintarroja común, a través de experiencias preliminares en ambiente controlado. Esta especie, endémica del Pacífico Sur-oriental, habita desde Perú (Ancón) hasta Chile Austral, preferentemente en aguas someras. Se colectaron cápsulas con huevos de pintarroja del medio natural, los cuales fueron mantenidos en un laboratorio húmedo. Después de la eclosión, las pintarrojas fueron criadas en estanques de 200, 500 y 1000 L de agua de mar, con flujo de agua constante y temperatura ambiente. Las dimensiones de los estanques utilizados dependieron del número y de la talla de los individuos. Durante el período de crianza en cautiverio las pintarrojas fueron alimentadas con una dieta húmeda, basada en una mezcla de harina de pescado, camarones, jibia y carne de pescado fresco, enriquecida con vitaminas y minerales. Nuestros resultados preliminares sugieren que las pintarrojas pueden ser criadas en cautiverio. La crianza de S. chilensis en cautiverio es un precedente para el cultivo de tiburones, los cuales pueden ser dirigidos, entre otras áreas y objetivos, a la investigación, a la conservación de poblaciones nativas y a la educación ambientalBreeding animals is a phenomenon associated to the origins of the modern man. Nevertheless, breeding marine species is related to the productive scope through intensive cultures in captivity to mainly commercial aims. This study aims to determine the feasibility of culture of the red spotted catshark, Schroederichthys chilensis, through preliminary controlled environment experiences. This species is endemic of the South-Eastern Pacific and lives from Peru (Ancon) to Southern Chile. The egg capsules of red spotted catshark were collected from its natural environment and then were maintained in the wet laboratory. After the hatching of the embryos, the red spotted catshark were maintained in tanks of 200, 500, and 1000 L of seawater with constant water flow and room temperature. The dimensions of the tanks depended on the number and size of the individuals. During the period of captivity, the red spotted catshark were fed with a moisten diet cradle in a mixture of shrimp, squid and meat of fresh fish, enriched with vitamins and minerals. Our preliminary results suggest that the red spotted catshark can be able to breed in captivity. The breeding of S. chilensis in captivity is a precedent for the culture of sharks, which can be directed to research, conservation of native populations, and environmental education, among other areas
