- Efecto de cuatro sustratos en el crecimiento y supervivencia de penaeus vunnumei en dos salinidades William A. Bray Addison L. Lawrence Ciencias de la Tierra The marine shrimp, Pennens varmnnei Boone, was cultured on four substrates at twosalinities for 56 days. Test substrates included three soils (fine sand, toarse sand and clay) and animpermeable substrate (bare fiberglass tank bottoms). Test salinities were 45 ppt and 27 ppt.Juveniles of 0.94 g mean weight were stocked at 15/n? in 1.2 m diameter, outdoor tanks. Resultsindicated that P. varmmri has no soil substrate requirement for the 1 to 15 g size categoty.Significantly higher final weights were observed with impermeablesubstrate than with any soilsubstrate at both salinities tested (15.1 g at 27 pot, 13.2 g at 45 ppt). Shrimp cultured on sandsubstrates had higher final weights than shrimp cuhured on clay, although the difference wasnot statistically significant in thc highcr salinity graup. Average weight gain ranged from 1.55 to1.77 g/week in the 27 ppt treatments and from 1.33 to 1.54 g/week in the 45 ppt treatments. 1993 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48019207 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.19
