These small pelagic fish feed on plankton and can    compete with each other for food, leading to potentially complexinteractions. Three forage fish species (<i>Sprattus fuegensis</i>,    <i>Strangomera bentincki</i>, and <i>Engraulis ringens</i>) are commonly    found in the inshore waters of Northern Chilean Patagonia, a region with    large spatial variability in oceanographic conditions and in the    zooplankton community. To better understand what factors may explain    coexistence among these three forage fish species, we examined differences    in resource availability (zooplankton community and abundances) in three    locations (Chiloé, Cordillera, and Aysén regions) within Northern    Patagonia. We compared the diet of the three fish species using both stableisotope and stomach content analyses, and we measured their gill rakers.    <i>S. fuegensis</i>, the only species found in all three regions, had    flexible diets which lent it greater success than the other two species at    foraging in waters with fewer prey. We found little diet differentiation    among the three species in the copepod-rich Cordillera region, but the    diverging diets of <i>S. bentincki</i> and <i>S. fuegensis</i> in the    copepod-poor Chiloé region suggest that diet partitioning in areas with    fewer resources is due to competition. The small differences in diet    facilitates coexistence among the three species, which may help explain the    lack of correlation between the three species’ population abundances in the    Cordillera region over the past 6 years. Finally, our results show that the    high degree of oceanographic heterogeneity in Northern Patagonia may    encourage species separation based on their specific environmental    requirements.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Small differences in diet facilitate the coexistence of three forage fish species in an inshore Northern Patagonian habitat","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:32:41.838491","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"trophic ecology; Northern Patagonia; forage fish; stable isotopes; zooplankton; diet partitioning; competition","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-10-06","DateCreate":"2022-03-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000759470400001","VABBcode":null,"OpenAcc":1,"DOI":"10.3389/fmars.2021.792377"},"refs":null,"anarec":{"AnaID":350587,"PubliDate":2022,"Pagination":null,"XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"792377","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":233602,"SerRR":"Frontiers in Marine Science.
