Samples were obtained from commercial landings at Rio Grande (1992-97). Age determination for 1159 fish indicated that gill-net and purse-seine fisheries caught 1-5 year-old and 1-7 year-old fish, respectively. Trawlers caught fish from ages 1 to 7. Because of their high degree of selectivity, the gill nets caught the larger individuals of ages 1 and 2, as well as the smaller individuals of ages 3-5. Faster-growing fish captured with gill nets had smaller scales than fish of a similar length caught with purse seines. By contrast, the slower-growing fish captured with gill nets had larger scale size than fish of a similar length caught with purse seines. For gill nets and purse seines, there were differences between the von Bertalanffy growth estimates derived from both mean values of backcalculated length-at-age and individual back-calculated length-at-age. We also recorded differences in growth parameters obtained from back-calculated length-at-age derived from measurements to the last annulus only and from measurements of all annuli up to the sampling age. Selectivity-related bias was incorporated in the estimation of growth parameters, yielding unrealistic estimates of L-infinity and k for the gill-net growth curve.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of gear selectivity and different calculation methods on estimating growth parameters of bluefish, <i>Pomatomus saltatrix</i> (Pisces: Pomatomidae), from southern Brazil","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Back-calculation; Atlantic coast; United-states; Gulf","OtherDescriptors":"BACK-CALCULATION, ATLANTIC COAST, UNITED-STATES, AGE, OTOLITHS, MEXICO, GULF","Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2014-08-20","DateCreate":"2001-09-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000170173200005","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":18014,"PubliDate":2001,"Pagination":"432-442","XtraPublOfAnaID":null,"ISBN":null,"Volume":"99","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44319,"SerRR":"Fishery Bulletin.
