Resumen

VEGA-VILLASANTE, F. et al. Growth and survival of prawn (Macrobrachium tenellum) in experimental cultures during summer and autumn in the tropical Mexican Pacific coast. Trop. subtrop. agroecosyt [online]. 2011, vol.14, n.2, pp.581-588. ISSN 1870-0462.

For aquaculture purposes, Macrobrachium íenellum is considered as a good candidate, is not aggressive nor presents cannibalism and can tolerate an ample interval of temperatures, salinities and oxygen concentrations. The present work evaluates the semi-intensive culture of M. íenellum under environmental conditions of summer and autumn with special attention to water temperature. The results of the experimental cultures in the tropical Mexican Pacific coast, suggest this species demonstrates better growth during the end of the spring, summer and the beginning of the autumn, time at which the average temperature of the water is near 30°C. The experimental cultures of end of autumn and beginnings of winter demonstrate minimum growth, with an average temperature of the culture water of 27°C. Other parameters like pH, O2 concentration and turbidity in the culture water were similar in all the experimental cultures reason why temperature is suggested the factor was the determinant in the differences found in growth.

Palabras llave : prawn; temperature; development; Macrobrachium; environmental conditions.
