In addition to the conventional conservation measures at the nature reserve, we suggest additional conservation actions to better protect juvenile Chinese sturgeon residing in the estuary; namely: (1) expanding the protected area and adding a seasonal component, from April to August, to afford better protection of juvenile Chinese sturgeon in the whole estuary, but particularly just upstream of the estuary mouth and in nearshore waters; and (2) banning all fishing activities and extending protection to the food resources (such as zoobenthos and small-sized fishes) of juvenile Chinese sturgeon in coastal shallows.</li>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Migration and feeding habits of juvenile Chinese sturgeon (<i>Acipenser sinensis</i> Gray 1835) in the Yangtze Estuary: Implications for conservation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-12 01:32:17.391636","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"conservation management, diet, nature reserve, stable isotope","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2023-07-24","DateCreate":"2023-07-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000453874900007","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/aqc.2935"},"refs":null,"anarec":{"AnaID":365814,"PubliDate":2018,"Pagination":"1329-1336","XtraPublOfAnaID":null,"ISBN":null,"Volume":"28","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42196,"SerRR":"Aquatic Conservation: Marine and Freshwater Ecosystems.
