A total of 47 variables (please refer to column 2 of Table 1) wereused for the analysis. Data gathered were mostly binary (yes/no)except for months of stocking or harvest, mangrove to pond area ratio(MPR), proximity to the sea or road (km), pond size (ha), water levelinside the pond (cm), and number of croppings/year. No scaling wasused in the case of the non-binary data. Data analysis was done in twosteps: variable reduction to increase model stability and binarylogistic regression to identify the protective and risk factors. WSSVincidence was used as the dependent variable that needs to beexplained. The procedure was applied to the entire dataset and to twosub-sets of the data: farms into monoculture, and farms intopolyculture. All the statistical analyses were done with SPS
