These are <i>Gracilariopsis longissima</i> and <i>Gracilaria gigas</i>. To evaluate species performance under the relevant range of salinities, we performed replicate laboratory experiments in which both species were exposed to different salinities ranging from 5 ppt to 30ppt under semi-controlled conditions. Highest growth rates were observed for <i>G. longissima</i> at a salinity of 10ppt. while for <i>G. gigas</i> similar highest growth rates were observed at 10ppt and 15ppt. However, <i>G. gigas</i> growth was less sensitive to small salinity differences at the lower salinity range whereas <i>G. longissima</i> performed better and more stable than <i>G. gigas</i> at the higher salinity range of 15 – 20 ppt. Apart from a few notable exceptions, <i>G. longissima</i> had a generally higher agar content than <i>G. gigas</i>, whereas <i>G. gigas</i> had a generally higher gel strength than, <i>G. longissima</i>. Our results show that neither species was superior in growth and quality criteria than the other species along the whole range of brackish water salinity conditions and farmers need to choose between them depending on their pond conditions and market quality criteria.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effect of salinity on growth, agar content and gel strength for two agaroid seaweed species: <i>Gracilariopsis longissima</i> and <i>Gracilaria gigas</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:33:21.997301","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Brackish; Pond; Hydrocolloid","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-12-17","DateCreate":"2025-12-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.ejar.2025.07.004"},"refs":null,"anarec":{"AnaID":436676,"PubliDate":2025,"Pagination":"524-528","XtraPublOfAnaID":null,"ISBN":null,"Volume":"51","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":226053,"SerRR":"Egyptian Journal of Aquatic Research.
