Information on the biology and ecology of the species, diet, in particular, is still scattered. Here, we explore the feeding habit, feeding intensity, and food composition of the squaretail mullet. A total of 942 fish (526 males and 416 females) were collected from November 2020 to October 2021 at four coastal sites in the Mekong Delta, Vietnam. The squaretail mullet is an algi\u2010omnivorous fish, as their relative gut length (1.81) falls into the range 1\u20133, and the diet is mostly based on algae. The feeding intensity is high due to the high value of the fullness index (4.39\u2009\u00b1\u20090.08%). The fullness index did not vary by sampling site and month, while RGL and FI changed depending on sex. Bacillariophyta (49.13%), detritus derived from organic matter (30.37%), and Cyanophyta (18.39%) are the dominant food items in the diet composition of <jats:italic>E. vaigiensis<\/jats:italic>, in which detritus is the most important food with the highest IRI index. Besides, Euglenophyta (1.00%), Chlorophyta (0.95%), Paramecium (0.06%), Copepoda (0.04%), Rotatoria (0.03%), Polychaeta (0.02%), and Cladocera (0.01%) are also recorded and ranked based on their biovolume. Some differences in diet composition are observed between immature and mature at different seasons and their interactions. Our results increase the knowledge about the feeding ecology of squaretail mullet and can help the sustainable management of this commercially important fish species.<\/jats:p>","DOI":"10.1002\/ece3.9352","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T05:53:47Z","timestamp":1663739627000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Feeding ecology of <i>Ellochelon vaigiensis<\/i> (Quoy &amp; Gaimard, 1825) living in the Mekong Delta, Vietnam"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9895-2039","authenticated-orcid":false,"given":"Quang Minh","family":"Dinh","sequence":"first","affiliation":[{"name":"Department of Biology, School of Education Can Tho University  Can Tho Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ngon Trong","family":"Truong","sequence":"additional","affiliation":[{"name":"Department of Molecular Biotechnology, Biotechnology Research and Development Institute Can Tho University  Can Tho Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7187-1896","authenticated-orcid":false,"given":"Ton Huu Duc","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Biology, School of Education Can Tho University  Can Tho Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3116-5599","authenticated-orcid":false,"given":"Tran Thi Huyen","family":"Lam","sequence":"additional","affiliation":[{"name":"Department of Molecular Biotechnology, Biotechnology Research and Development Institute Can Tho University  Can Tho Vietnam"},{"name":"Institute of High Quality Biotechnology\u2010Food Technology Cuu Long University  Vinh Long Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4603-4164","authenticated-orcid":false,"given":"Tien Thi Kieu","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Biology An Khanh High School  Can Tho Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5951-6816","authenticated-orcid":false,"given":"Dung Quang","family":"Le","sequence":"additional","affiliation":[{"name":"Institute for Circular Economy Development Vietnam National University \u2010 Ho Chi Minh City  Thu Duc City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0628-9995","authenticated-orcid":false,"given":"Simon Kumar","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences and Environment, Faculty of Science and Technology Universiti Kebangsaan Malaysia  Bangi Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"1","article-title":"The feeding habits and the morphology of the alimentary tract of some teleosts living in the neighbourhood of the Marine Biological Station, Ghardaqa, Red Sea","volume":"5","author":"Al\u2010Hussaini A.
