SS 10/95 (alternative identifier: SS199510)
Period: 1995-10-10 00:00 to 1995-11-05 00:00 UTC
Duration: 26.00 days
Region: Gulf of Carpentaria
Ship: Southern Surveyor [details]
Description:
Southern Surveyor cruise SS 10/95 was undertaken to test devices for the Bycatch Reduction in Prawn Trawls project in the area of the tiger prawn fishery west of Weipa, Gulf of Carpentaria. Aims of the cruise were to conduct prawn and fish bycatch reduction/video comparison trawls; EFN (environmentally friendly net) trawls, shark longlining, and to collect samples for the Hobart genetics group.
The night time prawn trawling was carried out 5 nm west of Duyfken Point and day time trawling in waters further west. Five bycatch reduction devices (BRDs) and a control or standard prawn net codend were tested and four of these BRDs were compared intensively. Daytime fish trawling with the EFN were carried out in waters 25 nm west of Duyfken Point. Video images were obtained of fish behaviour in the BRD codends of the prawn net and the EFN, and of the performance of the EFN over benthic structure. Samples collected included bycatch species for reference specimens and saurids for the Hobart genetics group. Longlining was successfully used to demonstrate its effectiveness at obtaining large numbers of sharks over short time intervals including dyed bait experiments.
