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.

Ongoing research studies on maturation and spawning of milkfish, Chanos chanos at the brackishwater shrimp and milkfish culture applied research and training project, Jepara, Indonesia KH Alikunhi - In Proceedings of the International Milkfish Workshop Conference, May 19-22, 1976, Tigbauan, Iloilo, Philippines, 1976 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe paper gives an account of the research work carried out at Jepara, Indonesia, on induction of maturity of milkfish in ponds and enclosures, and procurement of the spawners from the wild for seed production by hypophysation. Seven to eight years old pond grown milkfish were found sexually immature. Experiments are being conducted for growing and inducing maturity in 1-2 years old milkfish in fertilized ponds with regular tidal flow of water and also under regular hypophysation program. Milkfish spawners collected from sea had a few males in oozing condition and females mostly spent.
