On 25 August 2005, the SA Government closed the SASF in response to results from independent observer coverage in the fishery and concerns associated with encirclement and mortality rates of common dolphin.

The SASF TEPS Code of Practice developed prior to the fishery has been effective in reducing the encirclement and mortality rate initially reported but still requires improvement to ensure the fishery is operating sustainably.

Recent communication between PIRSA and SAMSSIA in relation to interim results from the observer program (July 2006 – June 2007) has highlighted that improvement of the SASF TEPS Code of Practice is an immediate priority.

Investigations by the SASF TEPS WG suggests there is scope to develop an acoustic mitigation signature that will further reduce the encirclement and mortality rate of common dolphins and improve the effectiveness of the TEPS Code of Practice.

Considering the importance the SA Government places on effective TEPS mitigation the development of underwater acoustic mitigation technology presents the greatest potential to improve the SASF’s TEPS Code of Practice.

This project will address FRDC’s strategic challenge to improve the management and use of aquatic natural resources to ensure their sustainability; has a high likelihood of success considering the success of acoustic behavioral modification on similar species(Leeney et al 2007) and in relation to the common dolphin (Morizur et al 2007) and has a high likelihood of adoption by industry as a successful outcome will be incorporated into the TEPS Code of Practice which is adhered to by 100% of the licence holders in the fishery.

The SASF is a key economic driver in the region and all efforts to maintain and secure access rights through the adoption of sustainable fishing practices are warranted.
