Factors affecting reproductive performance of captive and wild broodstock prawns

Project number: 1992-051
Project Status:
Completed
Budget expenditure: $717,563.00
Principal Investigator: Peter Rothlisberg
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 26 Sep 1992 - 18 Mar 1997
:

Objectives

1. To identify the causes of the seasonal variability in reproductive performance in wild caught and captive broodstock
2. To develop methods for assessing the nutritional condition of broodstock and monitor seasonal variation in prawns' diet and nutritional condition
3. To assess whether conditioning broodstock prawns in ponds prior to inducing spawning may be used to provide good quality spawners regardless of season or source of supply
4. Develop and evaluate formulations for a cost effective artificial diet for pre-spawning conditioning of broodstock prawns

Seafood CRC: optimisation of viral clearance from broodstock prawns using targeted RNA interference

Economic losses due to diseases mostly caused by viruses remain a major obstacle to realizing the production potential of prawn aquaculture industries in many parts of the world. Broodstock used in prawn hatcheries in Australia are generally managed quite intensively and numbers used are generally...

Seafood CRC: increasing seedstock production of domesticated giant tiger prawns (Penaeus monodon) through improved male fertility

Given the rationale that pond systems are likely the most cost-effective system for large-scale production of Giant Tiger Prawn (Penaeus monodon) broodstock, this project aimed to determine whether pond-rearing poses a significant risk for broodstock production. The gross reproductive development of...

DNA microsatellite variation in Atlantic salmon

The aquaculture of Atlantic salmon began in Australia in the mid-1960' s with an importation of ova from Canada to New South Wales. Anecdotal evidence suggested that the Australian population went through a severe bottleneck event during the early years due to poor survival and subsequent small...

Seafood CRC: genetic selection for Amoebic Gill Disease (AGD) resilience in the Tasmanian Atlantic salmon (Salmo salar) breeding program

Amoebic gill disease (AGD) continues to have a significant economic impact upon production of sea-farmed Atlantic salmon in Tasmania. Reducing mortality is economically important for the fish farmer and is equally important from an animal welfare perspective. The process of freshwater bathing...

BCA: DNA microsatellite variation in Atlantic salmon

This report carries out ex-post cost/benefit analysis on three Tasmania Atlantic salmon research projects carried out by CSIRO Marine Research, Hobart. The three projects are analysed together as all are concerned with examining genetic diversity in Tasmanian Atlantic salmon. In addition to the...

Development of the aquaculture capability of the brown tiger prawn (Penaeus esculentus)

In order to provide for future growth of the Australian prawn aquaculture industry, there is a need to take a longer-term strategic view and develop production technology for alternative species that can support an export market but do not have the intense overseas competition of the current major...

Atlantic Salmon Aquaculture Subprogram: molecular genetic tools for the Tasmanian Atlantic salmon industry – development and application

Archived DNA was successfully extracted from 30-year-old dried scales collected in 1971 and 1972 from wild Atlantic salmon from the River Philip, Canada. Genetic variation was assessed at 11 nuclear DNA microsatellite loci (three tetra- and eight di-nucleotide repeats) in two samples from the River...

Identification of a Y-chromosome marker in Atlantic salmon (extension to FRDC 95/80)
