| From October to April the growth of spat of <i>Ostrea edulis, Crassostrea gigas</i> and <i>Venerupis semidecussata</i> in an onshore nursery was recorded as a function of water temperature and food level. The results of this study indicate that even very eutrophic water, such as that of the Sluice Dock at Ostend, Belgium, does not provide enough microalgae to sustain growth of bivalve spat during winter, irrespective of whether the water is heated or not. It is necessary to supply additional food (cultured live algae). Food shortage for three months at higher temperature induced a stress situation resulting in high mortality rates, even after transferring all the spat into an optimal combination of temperature and food availability. |

| The controlled nursery culturing of mollusc spat produced to date by millions in commercial hatcheries is an intermediate step in mollusc farming which is receiving more and more attention. Different technologies for nursery culturing indoors as well as outdoors have been developed at different places.The principles are always basically the same and consist of culturing postlarvae of a few millimeters to a size of a few centimeters in densities as high as possible in specific devices containing seawater which is eventually enriched with live unicellular algae or inert foods. This paper reports on the first results obtained in Belgium in an indoor experimental nursery with spat of <i>Ostrea edulis, Crassostrea gigas</i> and <i>Venerupis... |
