On two semi-intensive shrimp farms studied in Mexico, RuizFernández
and Páez-Osuna (2004) reported that pond influent and
effluent BOD2 concentrations varied temporally, mean effluent BOD2
was greater, and no seasonal differences were detected. In a study of
Honduran semi-intensive shrimp farms, Teichert-Coddington et al.
(2000) estimated BOD5 from BOD2 measurements and showed water
exchange resulted in a net discharge of BOD5 of 103 kg ha−1 100 d−1
.
However, we found no published study that evaluated ultimate BOD and
the corresponding decomposition rate constant in semi-intensive
shrimp pond water
