Marine farmed Atlantic salmon (Salmo salar) are susceptible to recurrent amoebic gill disease (AGD) caused by the ectoparasite Neoparamoeba perurans over the growout production cycle. The parasite elicits a highly localized response within the gill epithelium resulting in multifocal mucoid patches at the site of parasite attachment.

Phenotypic sex in salmonids is determined primarily by a genetic male heterogametic system; yet, sex reversal can be accomplished via hormonal treatment. In Tasmanian Atlantic salmon aquaculture, to overcome problems associated with early sexual maturation in males, sex-reversed females are crossed with normal females to produce all female stock.

We studied the expression of 28 genes that are involved in vertebrate sex-determination or sex-differentiation pathways, in male and female Atlantic salmon (Salmo salar) in 11 stages of development from fertilization to after first feeding. Gene expression was measured in half-sibs that shared the same dam.

Farmed Atlantic salmon (Salmo salar) is a globally important production species, including inAustralia where breeding and selection has been in progress since the 1960s. The recentdevelopment of SNP genotyping platforms means genome-wide association and genomicprediction can now be implemented to speed genetic gain.

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 broodstock numbers.

This project primarily addresses physiological "robustness" in Atlantic salmon. Critical issues for the Tasmanian salmon industry include understanding the physiological response of salmon to hypoxia due to decreased dissolved oxygen (DO) and increases in other dissolved metabolic wastes.

One of the primary breeding goals of the Saltas selective breeding program is resistance to amoebic gill disease (AGD), which is the main health issue affecting production of Atlantic salmon (Salmo salar) in Tasmania.

The main health issue affecting Atlantic salmon marine aquaculture in Tasmania is amoebic gill disease (AGD), a parasitic disease which causes extensive gill pathology. AGD is treated by proactively bathing fish in freshwater, based upon regular assessment of the intensity and frequency of gross gill signs (“gill score”) in each caged population.

To identify the level of decline in genetic variation in Tasmanian stock of farmed Atlantic salmon

An outcome to date is the use of molecular markers by a member of the Atlantic salmon industry to pedigree and estimate relatedness of broodstock for the commencement of a selective breeding program.
