SS 03/98

[details]
J. Salini (CSIRO) Southern Surveyor cruise SS 03/98 is the final of three cruises for the Bycatch Sustainability project in the region of the northern prawn fishery in the Gulf of Carpentaria, north-east of Mornington and around Groote Eylandt. The objectives of this cruise are to identify all vertebrate and invertebrate bycatch species in prawn trawls inside and outside closed areas of the fishery; to sort one total catch from each area; and to collect RoxAnn and EK500 acoustic data on bottom environments, complemented by dredge tows, grab samples and abiotic data. The survival of trawl-caught sea snakes will also be monitored.
SS 08/97

[details]
J. Salini (CSIRO) Southern Surveyor cruise SS 08/97 was the second in a series of three cruises for the Bycatch Sustainability project in the areas of the northern prawn fishery of the Torres Strait and the Gulf of Carpentaria. The aims of the cruise were to identify all vertebrate and invertebrate bycatch species in 468 prawn trawls in the northern prawn fishery and the Torres Strait; to sort one total catch from each of nine areas (seven were successfully sampled); to sample inside and outside prawn closure areas north west of groote Eylandt; and to collect RoxAnn and EK500 acoustic data to help discriminate bottom environments, accompanied by dredge tows and abiotic samples. Sea snakes were also tested for post-trawl survival, and leiognathids (ponyfish) chemically treated for otolith marking.
SS 02/97

[details]
J. Salini (CSIRO) Southern Surveyor cruise SS 02/97 was the first in a series of three cruises for the Bycatch Sustainability project in the areas of the northern prawn fishery of the Torres Strait and the Gulf of Carpentaria. The aims of the cruise were to identify all vertebrate and invertebrate bycatch species in prawn trawls in the northern prawn fishery and the Torres Strait; to sort one total catch from each of nine areas; to complete subsampling prawn trawl experiments; to collect RoxAnn and EK500 acoustic data to help discriminate bottom environments, accompanied by dredge tows and abiotic samples; to collect saurid specimens for phylogenetic analyses; and to collect and photograph specimens of commercial fishes. Sea snakes were also tested for post-trawl survival, and leiognathids (ponyfish) chemically treated for otolith marking.
