Among other important characters, the food should be of suitable size to the small mouth bore of the predacious stages. Representatives of different Protozoa were found, among other preyed organisms, in stomach contents of fish larvae. Many Protozoa are known to have a high metabolic rate and a short generation time, and are therefore promising as a good potential food for fish fry. Presently under investigation are ciliates, 40- 700 µm in length, which were isolated from seawater and salt marsh: <i>Condylostoma sp., Fabrea salina</i> and <i>Keronopsis rubra</i>. Experiments for isolation and purification of these were carried out by combination of washing and antibiotic methods. A suspension of a mixture of organisms: <i>Tetraselmis suecica, Phaeodactylum tricornutum, Dunaliella primolecta, D. salina, Isochrysis sp., Monochrysis sp., Oxyrrhis marina</i> as well as different bacteria were added as food. The generation time varied with the temperature and salinity. Optimal growth values were 30-40 hr for the benthic ciliate <i>K. rubra</i> and <i>Condylostoma</i> and 12-20 hr for the planktonic ciliate <i>F. salina</i>. The latter also gave the highest yield of 500-1,000 cells/ml. These species demonstrated also a wide range of tolerance to salinity and temperature which is of advantage for their use as food organisms.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Cultivation of marine Protozoa","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-08 01:30:36.158493","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1976,"MonPub":null,"DateUpdate":"2019-06-14","DateCreate":"2000-11-22","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":4808,"PubliDate":1976,"Pagination":"241","XtraPublOfAnaID":null,"ISBN":"90-6281-001-2","Volume":"10","Issue":"1","BRefMon":4775,"BRefMonRR":"<b>Persoone, G.; Jaspers, E.
