D.5.3 | Rotifer Production: Liquid Microalgal Feeds


Microalgal feeds reduce all rotifer-related costs except the feed cost. Labor, space, management and other resource demands are all reduced. When all factors are considered most hatcheries find that the cost of using microalgal feeds is less, often far less, than alternative feeds.

Further, the nutritional quality of the rotifer and rotifer enrichment are higher, which in turn often translates into higher larval survival. Given the tremendous cost of running a hatchery, even a small increase in larval survival can have a major impact on total costs.
