Aellen (common name: sea purslane) is an edible saltmarsh halophyte traditionally consumed by humans living near coastal wetlands and is considered a promising extractive species for IMTA. To better understand its potential for IMTA applications, the present study investigates how artificial lighting and plant density affect its productivity and capacity to extract nitrogen and phosphorous in hydroponic conditions that mimic aquaculture effluents. Plant growth was unaffected by the type of artificial lighting employed—white fluorescent lights vs. blue-white LEDs—but LED systems were more energy-efficient, with a 17% reduction in light energy costs. Considering planting density, high-density units of 220 plants m<sup>−2</sup> produced more biomass per unit of area (54.0–56.6 g m<sup>−2</sup> day<sup>−1</sup>) than did low-density units (110 plants m<sup>−2</sup>; 34.4–37.1 g m<sup>−2</sup> day<sup>−1</sup>) and extracted more dissolved inorganic nitrogen and phosphorus. Overall, <span class=\"html-italic\">H. portulacoides</span> can be easily cultivated hydroponically using nutrient-rich saline effluents, where LEDs can be employed as an alternative to fluorescent lighting and high-density planting can promote higher yields and extraction efficiencies.","AbstractOtherLang":" sea purslane; hydroponics; aquaponics; light-emitting diodes; sustainable aquaculture; nature-based solutions; saline farming","BibLvlCode":"AS","StandardTitle":"LED lighting and high-density planting enhance the cost-efficiency of <i>Halimione portulacoides</i> extraction units for integrated aquaculture","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"sea purslane; hydroponics; aquaponics; light-emitting diodes; sustainable aquaculture; nature-based solutions; saline farming","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-01-14","DateCreate":"2021-05-31","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000659647700001","VABBcode":null,"OpenAcc":1,"Handle":"10.3390/app11114995"},"refs":null,"anarec":{"AnaID":338562,"PubliDate":2021,"Pagination":"4995","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":"11","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":263662,"SerRR":"Applied Sciences-Basel.
