The total weight of by-catch caught in the fishery was estimated at 6930 t (±900 t) in 1985 and 4630 t (±710 t) in 1986. A wide range of marine organisms including cephalo- pods, crabs, rock lobsters, scallops, sharks, rays, snakes and turtles were caught, but teleost fishes were the largest component: 5520 t (±970 t) in 1985 and 2910 t (±510 t) in 1986. Nemipteridae and Synodontidae, the main teleost families, made up 15% and 13% of the teleost catch by weight, respectively. Apart from small quantities of shovel-nose lobsters (Thenus orientalis), rock lobsters (Panulirus ornatus) and squid, all the by-catch (approximately 99%) was discarded. There was little change in the composition of the fish by-catch between the 2 years but there was a noticeable change in the fish : prawn ratio from 5.1 : 1 in 1985 to 3.3 : 1 in 1986. Samples of the Torres Strait trawl by-catch from trawl surveys in 1988 were used to estimate the component of the by-catch which floated (available to surface predators) and that which sank (available to mid-water and demersal predators and scavengers). Most of the discards sank (-70%) but an estimated 40% of the teleost catch (1200-2200 t) floated. Of the teleosts, over 75% of the Apogonidae, Nemipteridae, and Monacanthidae floated, whereas all Synodontidae, Mullidae and Bothidae sank. Although for five fish families there was a difference in the proportion that floated when shallow water (= < 25 m) trawls were compared with deeper water (26-55 m) trawls, this did not affect the estimates of by-catch that floated or sank.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"By-catch of the prawn fishery of Torres Strait; composition and partitioning of the discards into components that float or sink","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:31:08.676906","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2016-09-22","DateCreate":"2016-09-22","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1071/mf9900037"},"refs":null,"anarec":{"AnaID":261510,"PubliDate":1990,"Pagination":"37-52","XtraPublOfAnaID":null,"ISBN":null,"Volume":"41","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45097,"SerRR":"Australian Journal of Marine and Freshwater Research.
