摘要: | With the rising demand of ornamental aquatic organisms, there has been an urging request of breeding such species artificially for environmental protection. The major source of Amano shrimp Caridina multidentata, usually kept in freshwater aquarium for its algae-scavenging ability, is wild-caught. In this study, we focused on the larval culture of C. multidentata, which is a critical portion in its aquaculture. It has been known that salinity alteration is required for the growth and developemnt of the larvae of C. multidentata. We demonstrated that the optimal salinity and temperature condition for the larvae to survive is 34ppt and 24℃. Larvae could only accept microalgae as initial food, and Chaetoceros muelleri was better than Tetraselmis chui for its survival. We also found that the density of larvae in the container would not affect the survival rate of the larvae, until it was higher than 20 larvae per 500ml. The result of starvation resistance experiment showed that larvae could survive in a week after hatch without any food intake and fully-darkness condition would not increase the survival rate of larvae. |
