Versichele, D.; Bossuyt, E.; Sorgeloos, P. (1979). An inexpensive turbidimeter for the automatic culturing of filter feeders. Europ. Maricult. Soc. Spec. Publ. 4: 415-422

Automatization in the food distribution is necessary for the controlled culturing of filter feeders in high densities. Numerous devices have been described to distribute specific quantities of food suspension at preset time intervals (cf. review in Kinne, 1977). The number of systems which, however, add food whenever a preset critical turbidity of the medium is exceeded are rather limited. They furthermore are either very expensive (sophisticated equipment) or have to be cleaned very often (cf. review in Sorgeloos et al., 1976). We tried to simplify the technological complexity of the existing systems and developed an inexpensive, automatic, self cleaning food distributor. This apparatus measures the turbidity of the culturing medium which is pumped into a glass syringe, at regular time intervals. When a preset optical density is reached, the food distribution system is activated.
