We have analyzed stomach contents obtained in different habitats (mussel rafts, beach and central channel) over a diel cycle. <i>Pisidia longicornis</i> is the dominant species of the raft epifauna, and their megalopae made up over 70% of the diet of <i>L. friesii, T. luscus</i> and <i>C. lyra</i> in the middle ria zone, both in the culture areas and in the central channel. In the inner ria raft station the diet of <i>L. friesii</i> and <i>G. niger</i> was composed mainly of prey from the culture rope epifauna, but no megalopae were present. In the beach zones the diet of <i>G. niger</i> and <i>S. cinereus</i> was dominated by infaunal prey, mainly polychaetes. Due to the abundance of food provided by the associated epifauna, mussel culture influences the feeding habits of demersal fishes in the Ria de Arousa. In general, they fed throughout the day without a main period. However, the spring bloom of <i>P. longicornis</i> larvae changes the diel feeding activity patterns and diet of the demersal fish community. <i>S. cinereus</i> was the only species that showed higher fullness levels during the day in the beach zone, where <i>P. longicornis</i> megalopae were not present.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Diel feeding activity of demersal fishes in the Ría de Arousa (Galicia, NW Spain): an area of intense mussel raft culture","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1995,"MonPub":null,"DateUpdate":"2016-03-11","DateCreate":"2004-09-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1995TB09200006","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":66083,"PubliDate":1995,"Pagination":"141-151","XtraPublOfAnaID":null,"ISBN":null,"Volume":"36","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
