Dried Rotifer Sheet: A Novel Live Feed for Rearing First-Feeding Larvae.

Rotifers are now becoming a standard live feed for first-feeding larvae, because of their easy rearing protocol and improved growth and survival rate, compared with other fish feed, paramecia, and processed powder fish feeds. In a group of rotifers, bdelloid rotifer, a freshwater plankton, exerts cryptobiosis (an ametabolic state of life) in response to desiccation and survived for a long time. Here, we created "dried rotifer sheet" for rearing larvae in their early developmental stage.
