Use of metaldehyde as molluscicide in milkfish ponds
MetadataShow full item record
METAR metaldehyde formulations were tested under laboratory and faild conditions againts brackishwater pond snails (certhium so.). Under laboratory conditions the LC50 and LC99 3 days after treatment ranged from 2 - 3.5 and 4.8 - 5.4 kg/ha, respectively. However. these levels proved inffection when applied directly under actual pond conditions. In ponds with snail populatin of about 300/m2, a higher application rate of 30 kg/ha is recommended. Application of META metaldehyde concentrations of 0 - 175 kg/ha did not affect milkfish juveniles (1 - 3g body weight) 7 days after treatment. Results suggest that META metaldehyde formulations were effective for pond snail control without detrimental effect on juvenile milkfish.

Conference paperEO Tan, DL de Guzman, LC Darvin & MC Balgos - In JV Juario, RP Ferraris & LV Benitez (Eds.), Advances in milkfish biology and culture: Proceedings of the Second International Milkfish Aquaculture Conference, 4-8 October 1983, Iloilo City, Philippines, 1984 - Published by Island Pub. House in association with the Aquaculture Dept., Southeast Asian Fisheries Development Center and the International Development Research CentreDevelopment and directions in milkfish (Chanos chanos ) research in the Philippines from 1976 to the present are reviewed and analyzed. The problems of milkfish culture are dichotomous: low productivity vis-a-vis seasons of glut and price fluctuations. To intensify fish production extensive research has been conducted on fertilizer management, reclamation of acid sulfate soils, and pond construction and engineering. Research efforts have also been heavily directed toward increasing fry production through artificial propagation, improvement of fry collecting gear, and increasing fry survival through nutrition, control of parasites, and proper handling. Research on improved icing, packaging, and processing techniques along with market analysis are necessary for maximizing economic returns.
