Zooplankton is the most nutritious option, but its controlled mass production has not yet been achieved. In this context, we have developed a monoalgal ‘green water’ closed-loop bioreactor with the microalgae <i>Tetraselmis chui</i> that continuously produced the harpacticoid copepod <i>Tigriopus californicus</i>. During 145&nbsp;days of operation, the 2.2 m<sup>3</sup> bioreactor produced 3.9&nbsp;kg (wet weight) of <i>Tigriopus</i> with (dry weight) 0.79 ± 0.29% eicosapentaenoic acid (EPA), 0.82 ± 0.26% docosahexaenoic acid (DHA), 1.89 ± 0,60% 3S,3’S-astaxanthin and an essential amino acid index (EAAI) of 97% for juvenile Atlantic salmon. The reactor kept the pH stable over the operation time (pH 8.81 ± 0.40 in the algae phase and pH 8.22 ± 2.96 in the zooplankton phase), while constantly removed nitrate (322.6&nbsp;mg L<sup>−1</sup>) and phosphate (20.4&nbsp;mg L<sup>−1</sup>) from the water. As a result of the stable pH and nutrient removal, the bioreactor achieved zero effluent discharges. The upscaling of monoalgal, closed-loop ‘green water’ bioreactors could help standardize zooplankton mass production to supply the aquafeeds industry.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Intensive production of the harpacticoid copepod <i>Tigriopus californicus</i> in a zero-effluent ‘green water’ bioreactor","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:32:10.523050","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-01-11","DateCreate":"2022-01-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000741645800163","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-021-04516-w"},"refs":null,"anarec":{"AnaID":348877,"PubliDate":2022,"Pagination":"466","XtraPublOfAnaID":null,"ISBN":null,"Volume":"12","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
