Abstract

In order to meet the need of increasing yield and reasonable management of marine resources, artificial mass production of aquatic seeds and saplings are required. Accordingly, a great number of microalgae are required to be supplied stably to the seeds and saplings concerned. An experimental facility was developed for achieving a high-density cultivation of microalgae as feed for the seeds and saplings in early growth stages of bivalves, echinoderms and crustaceans. The experimental facility developed an optical radiant environment with culture-solution tank (capacity: 200 l) covered entirely with luminaries, which were composed of compactly single-capped three-band fluorescent lamps 55 W controlled by a dimmer. This set-up was able to produce a high lighting efficiency and a high uniformity ratio of photosynthetic photon flux density (PPFD, more than 300 μmol m^-2s^-1). The facility also had a water-bath to keep culture-solution at a constant temperature and an aeration control for aerating solution, as well as for washing and sterilizing tank based on high work efficiency. This experimental facility could readily become a practical way of achieving a stable supply of microalgae needed for the management of marine resources.
