Abstract
    The culturing of microscopic algae in sufficient quantities as a live food source for larval mollusks and crustaceans remains a major problem in many hatcheries, not at least from the technological and financial standpoint. Presently, a variety of more or less sophisticated techniques are utilized, depending on the degree of purity and/or algal volumes required. After considerable experimentation with a number of different technologies, the authors adopted a modification of the Salser and Mock algal culturing tank as a very convenient and cheap algal culturing system for small as well as large volumes of algae. For indoor culturing, the use of transparent culturing vessels (glass aquaria) illuminated laterally by fluorescent tubes allows a much better and more economical utilization of the expensive artificial light. PVC air-water lifts, inexpensive and easy to handle, assure a constant and most efficient circulation of the algal suspension, providing the maximal possible photosynthetic activity in indoor as well as outdoor conditions.
