SCRC: PhD : Understanding penaeid prawn sex determination and developing monosex induction strategies for commercial application (Andrew Foote)

Domestication and selective breeding programs in a number of cultured penaeid shrimp species worldwide have substantially improved commercially desirable traits compared to wild stocks. Improvements in growth rates, feed conversion efficiency, disease resistance and survival have been achieved in...

Summary

This study investigated the distribution of the expression of selected members of the peroxiredoxin (Prx) and glutathione peroxidase (GPx) antioxidant enzyme families in YTK (Seriola lalandi), an important finfish aquaculture species in South Australia.

The purpose of investigating the expression of these enzymes was to determine if they played a role in male fertility in fish, as both these families play a role in male fertility in mammals and individual members of these protein families were shown to be highly conserved between mammals and fish.

Experimental production of tetraploid oysters for use as broodstock for commercial hatchery production of triploids

Triploids (3n) are organisms with three sets of chromosomes, while the normal diploid (2n) organisms have only two sets. Over the past two decades, triploids have been studied in more than 20 species of molluscs. The main interests of those studies have primarily focused on their sterility and...

SCRC: PhD 6.06 – Capturing and maintaining genetic variation when initiating selective breeding programs for aquaculture

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market,...

SCRC: SCRC Honours Scholarship H3.1– Impact of commercial hatchery practices on the contribution of broodstock to offspring and genetic diversity in the Yellowtail Kingfish breeding program (Dr Alex Safari: Student Daniel Tan)

Using small numbers of broodstock for breeding often leads to random drift in gene frequencies between generations. Effective population size (Ne) is used as an indicator to assess the rate of inbreeding and loss of genetic variation in small populations. In this study we used six microsatellites,...

SCRC: PDRS: Use of next generation DNA technologies for revealing the genetic impact of fisheries restocking and ranching

Several initiatives by the Australian Seafood CRC’s Future Harvest theme involve some form of stocking or enhancement of fisheries. In Western Australia, populations of Roe’s Abalone (Haliotis roei) are currently being restocked after the occurrence of a catastrophic mortality event,...

Seafood CRC: Development of a genetic management and improvement strategy for Australian cultured Barramundi

The aim of this study was to review existing Barramundi-related genetic knowledge to identify relevant research and where the R&D gaps preventing instigation of Barramundi breeding programs presently exist. They identified and prioritised the research and steps that need to be taken to establish...
