애기물달팽이의 먹이인 조류(藻類)의 실험실 배양(培養)

Laboratory cultivation of blue-green algae for use as a food for Lymnaeids the intermediate host of Fasciola hepatica

In the present experiment, the blue-green algae, the principal food of the vector snail of Fasciola hepatica were cultured. Mud from good natural habitats was sterilized, made slopes, inoculated with algae from the habitats and maintained in a saturated atmosphere. Under the fluorescent-mercury lamp(100W) at about $20^{\circ}C$ the algal growth was optimal, taking 8 days to fully grow and to be ready for feeding the snails. The algae collected from the habitats and cultured in the laboratory were mainly green.
