| Table 2. Water quality variables (means of three replicates ± standard errors) for three different systems of shrimp culture: low density (LD), high density (HD), high density with recycling (HDR). Data reported for the HDR treatment represent only the culture pond. The R (treatment column) represents the oxidation pond only of the HDR treatment. Relevant comparisons were run among treatments; significance (S) and no significance (NS) differences are indicated within each column (P < 0.05). |
