Abstract

The Temperate Demersal Gillnet and Demersal Longline Fisheries (TDGDLF) are one of the main commercial shark fisheries in Australia. Most fishers in the TDGDLF use demersal gillnets to target sharks with scalefish taken in smaller amounts. Demersal longlines are also permitted but are not widely used. Demersal gillnets are size selective, but they do not necessarily discriminate among species, catching target and non-target species.

The Western Australian Fishing Industry Council (WAFIC) received funding as part of the Australian Government’s Our Marine Parks Grants Program to undertake research on the TDGDLF. This project was administered under the direction of a steering group consisting of WAFIC, the Department of Primary Industries and Regional Development (DPIRD), and the Southern Seafood Producers WA Association (SSPA).

This project addressed key questions (Is electronic monitoring a viable option for monitoring this fishery? Is the transition from gillnets to manual longlines viable? What are the socio-economic characteristics of this fishery?) relating to the use of demersal gillnets and demersal longlines by TDGDLF fishers. There were three parts to this project, (i) a desktop study, (ii) a 55-day field study using onboard observers and cameras mounted on demersal gillnets and demersal longlines, and (iii) a socio-economic survey.
