Aellen is a candidate extractive species for coastal Integrated Multi-Trophic Aquaculture (IMTA) to recycle the dissolved inorganic nitrogen (DIN) and phosphorus (DIP) wasted by excretive species. To test its suitability, saline aquaculture effluents were simulated in the laboratory using a hydroponics approach to cultivate the plants. Nutrient extraction efficiency, growth performance and nutritional profile were assessed under a range of DIN and DIP concentrations representing three different aquaculture intensification regimes and using Hoagland's solution as a control. Over a 10-week period, hydroponic units under non-limited N and P conditions displayed daily extraction rates between 1.5 and 2.8&nbsp;mg DIN-N&nbsp;L<sup>−1</sup>&nbsp;day<sup>−1</sup> and 0.1–0.2&nbsp;mg&nbsp;DIP-P&nbsp;L<sup>−1</sup>&nbsp;day<sup>−1</sup> and yielded between 63.0 and 73.0&nbsp;g&nbsp;m<sup>−2</sup>&nbsp;day<sup>−1</sup> of <em>H. portulacoides</em> biomass. Relatively to biomass produced, <em>H. portulacoides</em> extracted between 2.6 and 4.2&nbsp;mg&nbsp;DIN-N&nbsp;g<sup>−1</sup> and 0.1–0.4&nbsp;mg&nbsp;DIP-P&nbsp;g<sup>−1</sup>. The treatment with low-input of DIN and DIP (6.4&nbsp;mg&nbsp;N&nbsp;L<sup>−1</sup> and 0.7&nbsp;mg&nbsp;P&nbsp;L<sup>−1</sup>) induced some degree of nutrient limitation, as suggested by the extremely high extraction efficiencies of DIN extraction (99%) in parallel with lower productivity. The nutritional profile of <em>H. portulacoides</em> leaves is comparable to that of other edible halophytes and leafy greens and could be a low-sodium alternative to salt in its lyophilized form. From the present study, we conclude that the edible halophyte <em>H. portulacoides</em> can be highly productive in hydroponics using saline water irrigation with non-limiting concentrations of DIN and DIP and is, therefore, a suitable extractive species for coastal IMTA in brackish waters.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Testing the hydroponic performance of the edible halophyte <i>Halimione portulacoides</i>, a potential extractive species for coastal Integrated Multi-Trophic Aquaculture","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-25 01:33:17.474387","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sustainable aquaculture; Hydroponics; Halophytes; Nutrients; Plant nutrition; Remediation","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-05-12","DateCreate":"2021-05-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000617676800089","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.scitotenv.2020.144378","Handle":"10.1016/j.scitotenv.2020.144378"},"refs":null,"anarec":{"AnaID":337129,"PubliDate":2021,"Pagination":"144378","XtraPublOfAnaID":null,"ISBN":null,"Volume":"766","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43780,"SerRR":"Science of the Total Environment.
