Mortality rates are generally high and size-dependent. At the species level, these mortality rates are usually accompanied by correspondingly high growth rates. Here we provide examples from experimental studies with Atlantic cod (Gadus morhua) and Atlantic herring (Clupea harengus) larvae, in which multiple cohorts were followed over time. Body size, prey concentrations, and temperature are shown to influence growth rates. We present a method based on Cumulative size distributions (CSDs) for visualizing variability of sizes within cohorts over time. Analysis of CSDs revealed size-selective mortality and variations among populations in size- and temperature-dependent growth throughout ontogeny. We found that cod larvae consistently exhibit higher growth rates than herring larvae. While cod larvae may have an advantage over herring larvae when food availability is high, herring were more able to survive at low food concentrations than cod. Cod and herring seem to represent two growth strategies: cod larvae are relatively small at hatching and a high growth rate appears to be a prerequisite for success, whereas herring larvae are initially large, but grow more slowly.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"What can size distributions within cohorts tell us about ecological processes in fish larvae?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-24 01:31:50.295004","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"growth strategies; life history; mortality; prey concentration; sizedistribution; temperature; trade-off","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2009-11-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000271157200011","VABBcode":null,"OpenAcc":1,"DOI":"10.3989/scimar.2009.73s1119"},"refs":null,"anarec":{"AnaID":142184,"PubliDate":2009,"Pagination":"119-130","XtraPublOfAnaID":null,"ISBN":null,"Volume":"73","Issue":"Suppl. 1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43791,"SerRR":"Scientia Marina (Barcelona).
