However, it is unknown whether the demarcated zones correspond to the genetic stock structure of the world's most commercially important prawn, the giant tiger prawn (<i>Penaeus monodon</i>). Thus, this study used partial mitochondrial control region sequences (534 base pairs) to test the hypotheses that (1) giant tiger prawns in Tanzania's demarcated prawn fishing zones are a single stock and (2) the giant tiger prawns on the Tanzanian coast experienced a recent demographic expansion. The sequences showed high haplotype diversity (<i>h</i>&nbsp;=&nbsp;0.998–1.0) and low nucleotide diversity (θ<sub>π</sub>&nbsp;=&nbsp;1.89%–2.24%). The neutrality test and mismatch analysis showed that the hypothesis of recent demographic expansion could not be rejected. The analysis of molecular variance revealed low and insignificant fixation indices between the zones (<i>F</i><sub>ST</sub>&nbsp;=&nbsp;0.00025, <i>p</i> &gt; 0.05; Φ<sub>ST</sub>&nbsp;=&nbsp;−0.00027, <i>p</i> &gt; 0.05), suggesting that the three demarcated fishing zones constitute a single stock and that fishers may be targeting the same stock. Furthermore, it was discovered that Zone 2 has the potential to replenish depleted areas; thus, it should be prioritised in future conservation planning.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Genetic evidence for a single stock of giant tiger prawns <i>Penaeus monodon</i> in demarcated prawn fishing zones of Tanzania","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:32:29.872833","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"gene flow; genetic connectivity; genetic population structure; Giant tiger shrimp; mitochondrial displacement loop (D-loop)","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-02-27","DateCreate":"2023-02-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000874496400001","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/fme.12598"},"refs":null,"anarec":{"AnaID":361521,"PubliDate":2023,"Pagination":"36-43","XtraPublOfAnaID":null,"ISBN":null,"Volume":"30","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42700,"SerRR":"Fisheries Management and Ecology.
