The first experiment was designed to test for age-specific starvation with starvation trials at 0, 5, 15, 30, and 45 days after hatching. Mortality, length, and swimming activity data were collected. A second experiment was conducted to determine the effect of non-feeding conditions on the residency of prey in the gut at 5, 15, 30, and 45 days after hatching. The results of experiment 1 indicated that mortality occurred most rapidly at 15 and 30 days and was delayed during the yolk-sac period (day 0). Larvae in non-fed treatments showed significantly lower activity levels, except in the 45-day treatment, and the reduction in activity occurred before the onset of mortality. In experiment 2, gut residencies displayed an age-dependent response, with 5- and 45-day-old larvae having significantly shorter residency times. We conclude that beyond the yolk-sac period, cod larvae exhibit an age-dependent trade-off between growth and starvation risk. Larval age also influences patterns of gut fullness over time, with the fastest rates of gut clearance found at first-feeding and metamorphosis.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The risk of running on empty: the influence of age on starvation and gut fullness in larval Atlantic cod (<i>Gadus morhua</i>)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:25.879044","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2004-02-10","DateCreate":"2004-01-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000186573400010","VABBcode":null,"OpenAcc":0,"DOI":"10.1139/F03-108"},"refs":null,"anarec":{"AnaID":56746,"PubliDate":2003,"Pagination":"1289-1298","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42535,"SerRR":"Canadian Journal of Fisheries and Aquatic Sciences = Journal canadien des sciences halieutiques et aquatiques.
