This set of experiments compared the growth performance, survival and health of yellowtail kingfish (YTK) sourced from two different hatcheries (Strain 1 and Strain 2) fed on various diets over a commercially relevant time period of 56 weeks (ca. 13 months). Fish health was assessed routinely...

We have demonstrated that yields of 10 tonnes of fish per hectare cannot be sustainably achieved in static, autotrophic saline (14 ppt) ponds (i.e. ponds dominated by photosynthetic organisms) over a 3-4 month production cycle, despite the removal of settable wastes from the SIFTS. The outcome of...

The results of this study show that hatchery-reared Black Bream can be used to enhance the stock of the population of this commercially and recreationally important species in the Blackwood River Estuary in which it has become depleted. An initial trial of different stains demonstrated that alizarin...

High incidences of malformation and low level survival are common during Yellowtail Kingfish larviculture and it has been hypothesised that this is a result of excessive harmful bacterial loads within the culture tanks. The current rate of malformation and survival continues to impact heavily on the...
