treatments and one untreated contro

treatments and one untreated control were assigned randomly with 12 replicates (pans) each. For Agnique, 10, 24, and 48.5 ml was added to each enamel pan, approximately equivalent to the label rate range of 1.89, 4.73, and 9.45 liters/ha. Similarly, three treatments and one untreated control were assigned randomly with 12 replicates each. After treatment, the rearing pans were held in the insectary at 25-28° C and a photoperiod of 16:8 (L:D). Carapace length as a growth parameter was measured and mortality was recorded daily until all shrimp died, and the size at death as indicated by CL was determined. After the death of all TPS, rearing water was slowly drained, soil at the bottom of the enamel pans containing fresh TPS eggs was dried at 28-30° C, and eggs in the dried soil were then counted according to the procedures of Su and Mulla (2001). The daily growth was charted, and comparisons in size at death, longevity, and fecundity were
