Strong positive correlations were observed among all BOD estimates
during the dry season, and BOD
5
−2
in estuarine
was highly predictive of BOD
or
UBOD (Table 4). Water quality variables (TAN, chlorophyll a, and TSS)
also were positively correlated with dry season BOD estimates, but only
chlorophyll a was predictive of BOD. There also were positive
correlations among TSS and chlorophyll a and TAN. No correlations
were detected during the dry season among any variable and
cumulative feed addition or cumulative N addition. Dry season
estimated shrimp biomass was negatively correlated with water quality
variables, but no correlation was strong enough to be predictive.
