The effect of four substrates on growth and survival of Penaeus vannamei at two salinities

Abstract

Penaeus vannamei has no soil substrate requirement for the 1-15 g size category. Significantly higher final weights were observed with impermeable substrate than with any soil substrate at both salinities tested (15.1 g at 27 ppt, 13.2 g at 45 ppt). Shrimp cultured on sand substrates had higher final weights than shrimp cultured on clay, although the difference was not statistically significant in the higher salinity group. Average weight gain ranged from 1.55-1.77 g/week in the 27 ppt treatments and 1.33-1.54 g/week in the 45 ppt treatments. -from Authors
