Future oysters CRC-P: Species diversification to provide alternatives for commercial production

Pacific Oyster Mortality Syndrome (POMS), the disease caused by OsHV-1 microvariant, results in high and rapid mortality in Pacific Oysters (Crassostrea gigas) and has been responsible for significant economic loss to oyster industries in Australia and around the world. The diversification of...

Habitat modification and its influence on prawn and crab fisheries

Experimental trawling in Gulf St Vincent indicated that epifaunal assemblages experienced substantial trawling mortality, which varied depending on sediment characteristics. Locations with strong currents and coarse sediments experienced minimal effects, whereas those with weak currents and...

Need

The Northern Zone rock lobster fishery of South Australia is extensive covering an area of approximately 207,000 km2. The fishery has been managed under a total allowable commercial catch (TACC) since 2003. The current TACC is 345 tonnes, the majority of which is taken in inshore waters in the eastern region of the zone. The fishing season extends from November 1 to May 31 of the following year, with a closure from June to October inclusive. This project is an industry-led initiative that aims to explore alternative fishery management arrangements at both spatial and temporal scales.

From a spatial perspective, a number management of options are currently being considered for the fishery. Broadly, these options aim to encourage, through financial incentives, higher levels of exploitation in both western and offshore regions. Currently, estimates of biomass in the fishery are non-spatial. Fundamental to any spatial option is the need to generate spatial estimates of biomass to ensure that any increase in catch from peripheral regions is sustainable from a management perspective. This project aims to generate spatial biomass estimates based on historical logbook catch returns using the qR rock lobster fishery model which has been specifically developed for this fishery.

From a temporal viewpoint, industry wish to examine the possibility of an extended fishing season to enhance profitability by providing product during a period of low supply and higher prices. Currently, there are no available fishery or biological data from any of the four regions during the closed season from June to October. In particular, there is a need to attain information on the proportion of ovigerous (spawning females) in the catch during this period. Through a number of dedicated surveys, this project aims to provide a detailed catch breakdown in each fishery region during the current closed season.

Objectives

1. To provide spatial estimates of rock lobster biomass in the Northern Zone rock lobster fishery based on historical catch and effort data.
2. To provide a detailed breakdown of catch composition from dedicated surveys undertaken in the Northern Zone rock lobster fishery from June to October inclusive.

Immuno-staining of a ciliate protozoan causing significant mortalilty of farmed tuna: the development of a rapid identification technique which will enable improved farm management practices to be implemented to minimise fish mortality

An immunofluorescent staining technique for the rapid detection of the ciliate protozoan Uronema sp. was developed during 1995 and 1996. The initial test was developed using seven cultures of Uronema sp. from various sources which were identified as Uronema nigricans by microscopical and...

Identification and management of potential food safety issues in aquaculture-produced yellowtail kingfish (Seriola lalandi)

Hazards such as dioxin (PCDD/F) and PCBs have been identified in manufactured feeds as priorities for further investigation by industry. These issues are now being discussed by the South Australian Marine Finfish Farmers Association Inc (SAMFFA) and Australian feed manufacturers as part of...

King George Whiting spawning dynamics in South Australia’s southern Gulfs: to inform improved assessment and management of the resource

This study investigated the spawning dynamics of King George Whiting (Sillaginodes punctatus) in South Australia’s southern gulfs and Investigator Strait. King George Whiting is one of the most valuable and iconic coastal finfish species of southern Australia. In South...

Seafood CRC: sustainable feeds and feed management for Yellowtail Kingfish

Yeilowtail Kingfish, Seriola lalandi, is the main closed cycle flnfish cultured in South Australia (SA) and this industry has great potential to expand in other states of Australia. One of the major inefficiencies identified by industry was feeds and feed management in Yellowtail Kingfish...
