The Methodology Of Bryozoa Cultivation In The Laboratory Conditions

The main aim of the study was to develop and verify a methodology for the cultivation of bryozoans in laboratory conditions. For the experiment, the bryozoan of the species Plumatella emarginata was used. The colonies came from the recirculating system of circular tanks located at Mendel University. The colonies of P. emarginata were placed into aquaria in adjusted Petri dishes and started to attach to the dish walls after 2-3 days. A total of 28 adjusted Petri dishes were used in 6 tanks. Majority of colonies (70%) Were attached after 14 days. The colonies were not fed during the first trial while a mixture of green algae was offered to them during the second trial. Although the colonies were cultivated in optimised conditions, they did not grow any further and all colonies in both trials died after one month. We did not succeed in developing and verifying a methodology for the cultivation of bryozoans in laboratory conditions.
