Ibler, Benjamin
The author gives a survey about keeping and breeding of sea squirts (Ascidiacea) at both Zoo-Aquarium Berlin and Tierpark Berlin. Eight different species from different families could be presented, mostly solitary ascidia. Two pacific sea squirt species (H. aurantium and H. roretzi) have been imported from the Bay Peter the Great from the Japanese Sea to the Tierpark via Moscow. The Mediterranean species Halocynthia papillosa belongs to the stock since the times of director Werner Schröder. Ciona instestinalis reproduces very well by division of individuals forming clones. Only two tropical ascidias have been kept on evidence. Botryllus schlosseri belongs to the synascidia and has been acquired 1968. It was present until 1976.
