Die Zucht von niederen marinen Wirbellosen und ihre Anwendung in der experimentellen Zoologie

Abstract

This paper summarizes the present status of our knowledge concerning the cultivation of lower marine invertebrates. On the basis of the author's own work and experience, the term "culture" is defined and the advantages of continuous laboratory cultivation for experimental investigations are considered. The prerequisites for successful cultivation and containers, suitable for cultivating small marine invertebrates, are discussed. Special attention is paid to the selection of species for culture work and to the major factors known to be important in regard to culture techniques (seawater, O2-supply, water movement, food, temperature, light). Further points considered are: provisions for maintenance of a biological steady-state system in cultures; mono- and polyxenic cultures. Some examples of scientific results obtained by cultivation of marine invertebrates are presented. © 1970 Biologischen Anstalt Helgoland.
