Developing detoxification and purification technologies of ponds with pesticide residue for organic tiger shrimp farming development

Abstract

The technological improvement of marginal land was conducted through examination on three treatments; land soaking and washing (A), land remediation (B) and land reclamation (C). The highest average closure rate of klekap (66.667±5.774 %) was gained from B, and the highest average closure rate of Chaetomorpha sp (88.667±8.083 %) was derived from A. The Apocyclopas discovery through the study can become preliminary information to reveal the existence of Phronima Suppa, the indicator of tiger shrimp farming success. The land remediation (B), followed with contaminants detoxification employing plankton, is more effective in eliminating pesticide residue, depressing bacteria population and creating quality water and pond bottom soil according to the organic tiger shrimp production standard.
