Selectivity and catch composition among gears were determined by studying the species richness, diversity, size and mean trophic level of the catches for each gear type, to develop gear-based management recommendations for this artisanal reef lagoon fishery. One hundred and sixty-three reef and reef-associated species from 37 families were recorded in the catch. Beach seines and small traps accounted for the highest number of fish landed (34-35 individuals per fisherman per day). These gears also caught smaller fish than big traps, spears and gill nets. Beach seines caught the highest number of species (14 +/- 7 species per day) while most other gears caught four to five species per day with no differences between gears. Predatory species with a mean trophic level of 3.6 dominated catches from hand lines, while the mean trophic level of the other gears was low and ranged from 2.6 to 2.9 with no differences between the gears. The high diversity and small size of fish caught in beach seines indicates that its selectivity overlapped most with large traps and gill nets. Spears and small traps also showed high similarity in species selectivity and small traps captured the smaller mean size of fish, indicating that they are likely to pre-empt the resource of spears. Large traps, hand lines and spears catch the largest individuals and the species composition of the catch differed sufficiently such that their selectivity should overlap the least and may, therefore, be the preferred mix of gears. The elimination or reduction of beach seines and small traps should reduce the catch of small fish and overlap in selectivity among the existing gears.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Gear-based management of a tropical artisanal fishery based on species selectivity and capture size","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":"Artisanal fishing, coral reefs, gear selectivity, multi-species fishery, nets, seagrass, traps","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2013-08-02","DateCreate":"2012-12-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000188353800007","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/j.1365-2400.2004.00358.x"},"refs":null,"anarec":{"AnaID":221069,"PubliDate":2004,"Pagination":"51-60","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42700,"SerRR":"Fisheries Management and Ecology.
