Freshwater shrimp are a valuable aquatic product, in terms of their high economic value, for the people living along the rivers of Laos. However, no freshwater shrimp farming system has thus far been established in Laos. With the aim of developing such technique in Laos, the present study found four local species, Macrobrachium dolatum, M. eriocheirum, M. amplinus, and M. dienbienphuense, inhabiting Luang Prabang province. M. dolatum was selected for further study because of its relatively greater body size and fecundity, which are desirable features for aquacultural purposes. Hatched larvae were obtained from wild broodstock reared in an experimental tank. Next, a larval rearing trial was conducted on M. dolatum, using freshwater and brown pond water, and survival rates were observed for 4 weeks. The survival rate at 4 weeks of rearing was 1.8% and 20.5% when the larvae were reared in freshwater and brown pond water (collected from a fish-rearing pond), respectively. Further studies, such as using salt water as rearing water, are in progress to elucidate preferable rearing conditions for the larvae of M. dolatum. |
