Efficacy of Bayluscide against Cerithidea cingulata, a snail known as the significant pest to a semi-intensive shrimp farms were performed under laboratory trial. Ten liter aquarium containing 5 cm dept of mud, 2 liters of 25 ppt seawater and 300 snails were set with 2 replications. Six levels of the compound's concentration ranging from 0 1 2 4 6 and 8 ppm were tested with each group of the snails. The retention time of these solutions were determined after 3 4 and 5 days of application using mudcrab (Scylla serrata) and blood cockle (Anadara granosa) as the indicators. The results showed that 65 percent of the snails were killed at 8 ppm of Bayluscide within 24 h and hundred percent of the tested snails were killed under this concentration at 48 h. Nor mortality was observed in mudcrab and blood cockle which were exposed to 5 days retentive Bayluscide for 120 h.
