Improving mortality rate estimates for management of the Queensland Saucer Scallop fishery

This research was undertaken on the Queensland saucer scallop (Ylistrum balloti) fishery in southeast Queensland, which is an important component of the Queensland East Coast Otter Trawl Fishery (QECOTF). The research was undertaken by a collaborative team from the Queensland Department...

Establishment of a Coastal Habitat Resources Information System for Qld (CHRIS)

More than 100 key datasets relevant to coastal habitat management and for monitoring the condition and trend of fisheries habitats in Queensland have been integrated into the Coastal Habitat Resources Information System (CHRIS) during this establishment phase. Design of this geographic information...

A study of seagrass prawn nursery grounds and juvenile prawn populations in north Queensland

Seagrasses are of immense ecological importance in marine ecosystems. Primary production rates for seagrass beds are amongst the highest recorded for marine and terrestrial systems. They have a well documented role as animal habitat, nursery grounds, and as substrate stabilizers. The proximity of...

Barramundi origins: determining the contribution of stocking to the Barramundi catch on Queensland's east coast

Researchers from Queensland’s Department of Agriculture and Fisheries, James Cook University, and the University of Western Australia tested a range of otolith-based and genetic methods to identify hatchery-born from wild-born Barramundi. The project took place in the Dry Tropics region, where...

Diagnosis and prevention of the mid-crop mortality syndrome of pond-reared black tiger prawns (Penaeus monodon)

Objectives

1. To refine the detection system (hybridisation and PCR) to ensure the best sensitivity and specificity for a test to detect the MCMS agent
2. To clearly identify the risk factors which aggravate the expression of clinical MCMS, including the role of blue green algae
3. To establish a model screening program which allows hatchery and farm production with virus-free prawns
4. To deterine a cost effective, environmentally sensitive disinfection program to eradicate the MCMS agent from farms and hatcheries which will be a model for future disease emergencies

Summary

The project has created knowledge which has led to the outcome of better health management on Australian prawn farms. Changes to farm practices have occurred where whole-farm destocking and pond disinfection are applied as a hygiene practice following a season where crop declines or failures are seen. During, and subsequent to, the project prawn farmers now understand that infectious disease can affect cultured marine prawns in earthen ponds. As a consequence many farmers will submit sick prawns for diagnostic analysis soon after stressed prawns are seen in ponds, not assuming the problems are due to pond environment factors.

The project has contributed to the recovery of the Queensland prawn farm industry from the low production seen in the 1995/96 season of 1,294 tonnes (worth $28.2m) to 1855 tonnes (worth $32.4m) reported in 1998/99. A similar outcome is reflected when Australian marine prawn production is considered; from a low of 1,400 tonnes in 1994/95 to 2,059 tonnes of production in 1997/98.

The project has shown that a virus associated with Mid-Crop Mortality Syndrome is passed from breeders to their progeny. The project has created the knowledge of a detection test and that application of that test can be used by hatcheries to reduce the effect of the virus on productivity in the hatchery and farms.

Assessment of Queensland inshore net fisheries

Most of the world’s marine fish harvest still comes from coastal waters despite the rapid development of distant water fishing fleets (McHugh, 1967). Fish yields from estuaries and lagoons are generally high, due to factors including shallowness, inflow of nutrients from rivers, and the...

Aquaculture Diet Development Subprogram - Replacement of fishmeal in diets for barramundi - improving nutritive value of alternative feedstuffs using crystalline amino acids

Australia has an abundant supply of terrestrial animal and vegetable protein feeds which has the potential to at least partly if not fully replace the fishmeal presently used in compounded aquaculture diets. A major difference between marine and terrestrial protein sources is the marked difference...
