WSSV incidence is reported when white spots were observed on
the shrimp body, with or without laboratory confirmation. Monoculture
farms are those farms that culture Penaeus monodon only.
Polyculture farms culture P. monodon with other species such as
milkfish, crab, and tilapia in the same pond. Entire dataset refers to the
combined monoculture and polyculture farms.
