Both inlet- and pond-water were monitored for nitrate, phosphate, chlorophyll and adenosine triphosphate over a 9 day period. The interpreted results suggest that the growth of biomass in the pond became nitrogen limited, after which, at pseudo-steady state, the autotrophic biomass was about 686 mg C/m², and the heterotrophic biomass 288 mg C/m². Net primary production under these conditions was 313 mg C/ m²/day and heterotrophic production was 82 mg C/m²/day. This would indicate that 33% of the net photo-assimilated carbon was being excreted as dissolved organic carbon during this period. The obtained values are considered as minimal because of uncertainty in the C:CHL:ATP ratio used. The conclusion reached is that an efficient system would have to include animals feeding on planktonic heterotrophs as well as on autotrophs and phytodetritus.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Studies on a production system using a large volume floating pond","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-08 01:30:36.439768","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":"2000-11-29","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":4870,"PubliDate":1976,"Pagination":"457-466","XtraPublOfAnaID":null,"ISBN":"90-6281-002-0","Volume":"10","Issue":"2","BRefMon":4844,"BRefMonRR":"<b>Persoone, G.; Jaspers, E.
