An average of 25 individuals of all sizes were collected each month. Using microscopic characteristics of the gonads three gonadal stages were described: (1) immature; (2) mature, and (3) spent. Mature individuals showed statistically different morphometric characteristics. I. fuscus was continuously sexually mature throughout the year independent of changes in sea water temperature. Mean oocyte diameter indicated planktotrophic larval development. Mean fecundity for this species was 567,884 (±95,528 SE) eggs per gonad. Size at first maturity was between 161.0 and 170.9 g drained weight and the smallest individual found with mature gonads had a drained weight between 121.0 and 130.9 g. The population sampled ranged between 13 and 31 cm (81.0–400.0 g) with less than 10% of the population of individuals =25 cm (=300.0 g). No juveniles were recorded.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reproductive biology and population structure of the sea cucumber <i>Isostichopus fuscus</i> (Ludwig, 1875) (Holothuroidea) in Caamaño, Galápagos Islands, Ecuador","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-20 01:32:46.884530","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2016-07-06","DateCreate":"2016-07-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000247308000007","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-007-0640-1"},"refs":null,"anarec":{"AnaID":259651,"PubliDate":2007,"Pagination":"2091-2098","XtraPublOfAnaID":null,"ISBN":null,"Volume":"151","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
