This data represents research conducted as part of a PhD project on captive Striped Trumpeter (Latris lineata). Trials were conducted to investigate hormonal induction of spawning using LHRHa and the effects on testosterone and estradiol in wild and captive fish. Data was also collected on the number and quality of eggs, sperm counts and photo thermal data to record the effect on reproduction.
-
This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). Recorded taxonomy of copopod parasites and investigated potential treatments over the lifecycle of two parasites: caligus and condracantha, in hatchery reared Striped Trumpeter.
-
A comparison was made of sediments and associated macrobenthos at sites sampled within 42 fish farm leases distributed across Tasmania. Several key biotic and abiotic metrics recommended in previous studies for assessing environmental impacts of fish farm waste were investigated.
-
Data collected includes growth, survival, development (swim bladder inflation, flexion, metamorphosis), health, water quality, systems (tank size etc), nutrition (live feeds, lipids, vitamins) for hatchery reared striped trumpeter (Latris lineata).
-
Recorded details of visual field ontology (video images recording feeding response and histology of eye and jaw development), behaviour, feeding and jaw development and malformation in larval striped trumpeter (Latris lineata).
-
This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). As the culture of striped trumpeter moves towards commercial scale grow-out, knowledge of the immune system as it relates to disease resistance and vaccination is becoming more important. This study began at the basic level of immunoglobulin (Ig) characterisation and then moved onto the creation of anti-serum, which was used as an immunological tool to investigate the onset of the antibody response in the striped trumpeter. Information recorded included, the characterisation and immune response of hatchery reared striped trumpeter.
-
This data represents research conducted as part of a PhD project on Greenback flounder (Rhombosolea tapirina). Larvae were reared in either green water (Tetraselmis suecica) or clear water tanks during short-term feeding trials to investigate the effect of larval culture history, live prey density, and turbidity level on feeding performance.
-
For hatchery reared striped trumpeter (Latris lineata) data has been collected on length, weight, age, growth, size at metamorphosis, survival in relation to fish density, nutrition, health and system operation (tank size, water volume and quality, oxygen content).
-
This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). Recorded the prevalence of Kudoa neurophila (a myxozoan parasite formerly known as Pentacapsula neurophila) in relation to age for hatchery reared Striped Trumpeter using histology and PCR testing. Histology and in situ hybridisation techniques were incorporated into the study of the histopathology of the disease caused by this parasite to elucidate its entry point on the fish host and migratory pathway to terminal stage sporulation.
-
Data is primarily volume of eggs (naturally spawned and stripped) taken from different photo-thermal held brood stock groups of Striped Trumpeter (Latris lineata). Supporting data includes feeding, animal health and weight and environmental parameters (water quality).
