Juvenile production of the reshwater prawn Cryphiops caementarius (Decapoda: Palaemonidae) under laboratory conditions in Coquimbo, Chile

Abstract

Two culture experiments from 1995 until 1997 were carried out with larvae obtained from gravid females of Cryphiops caementarius (Molina 1782), to define a methodology in order to produce juvenile using controlled conditions of water temperature, salinity and feeding. Time in culture of larval development and the survival rate were determined. Two distinct types of culture systems were studied. Both systems incorporated a standard alimentation using nauplius of Artemia sp. plus microalgae; however the second system included, in addition, a supplement of fish and chiken eggs. The decrease in survival rate in both cultures systems was related to morphological changes in each stage of development. Juveniles were obtained after 98 days of culture with the first culture system, whereas in the second culture system, the time to reach the first juvenile stage was 62 days. In addition, an increase in the values for metamorphosis synchronism induced a good amount of metamorphosed animals (juveniles) during the time involved in this study.

Evaluación Poblacional del Camarón Cryphiops caementarius en Ríos de la Costa Sur del Perú

“…N.° 312-2006-PRO-DUCE establece medidas referidas al periodo de veda definida del recurso, la que está orientada únicamente a la protección de una fracción de la población (stocks comerciales y precomerciales en el periodo de máxima actividad reproductiva), no habiéndose establecido cuotas de captura. Estudios realizados en Chile (Meruane et al, 2006) muestran que la «crianza» (engorde) de la especie a escala comercial contribuiría a la producción sostenible y bajaría la presión sobre sus stocks.…”

Experiencias y resultados de investigaciones sobre el camarón de río del norte CRYPHIOPS CAEMENTARIUS (MOLINA 1782) (DECAPODA: PALAEMONIDAE): HISTORIA NATURAL Y CULTIVO

“…Rivera et al (1987), logró postlarvas en 220 días, y la descripción de los estados de desarrollo larval alcanza hasta la etapa de zoea 10, considerándola como el estado premetamórfico. Finalmente, Meruane et al (2006) obtuvo juveniles a los 61 días de cultivo con un importante aumento en la sincronía de la metamorfosis.…”

The northern river shrimp Cryphiops caementarius (Decapoda, Palaemonidae), research chronology between 1958 and 2008, II: aquaculture research and development in northern Chile

“…The first descriptions were from Bahamonde & Vila (1971) and this study was the basis for future Chilean and Peruvian studies on reproduction and bioecological conditions for larval development (Miranda & Weinbom, 1972;Sanzana, 1976;Munaylla, 1977;Norambuena, 1977;Viacava et al, 1978;Vegas et al, 1981;Baez et al, 1983;Rivera et al, 1983;Gil, 1988;Meruane et al, 1996;Galleguillos, 1997;Morales, 1997;Meruane et al, 2006a, b). Under natural conditions, the larval stages occur mainly in estuarine environments where marine Zooplankton is available, while the juveniles and adults migrate to the rivers (Rivera et al, 1983;Gil, 1986;Meruane et al, 1996;Galleguillos, 1997;Morales, 1997;Meruane et al, 2006b;Morales et al, 2006).…”
