Off-flavour taint of aquaculture products is a global issue reducing consumer confidence in the farmed produce as they are taken up via the gills of fish,and deposited in the lipids of the *** the fish are not purged,resulting undesirable muddy earthy flavour taint can be tasted by *** undesirable flavour and odour is caused by the terpenoid compounds namely geosmin and 2-methylisoborneol,produced as secondary metabolites by certain bacteria including the cyanobacteria and *** strategies to remediate the problem rely on treating the symptoms not the cause and involve the use of time consuming purging methods and costly *** control using bacteriophages,specific to the problem causing bacteria,offers a natural alternative to chemical control,which might reduce further complications of copper based algaecides and its subsequent implications on water *** an adaptation of such biological control approach streptomycetes isolated from barramundi ponds were tested for their susceptibility to streptophages to understand whether host destruction via phage lysis would subsequently eliminate off-flavour taint productions by these *** the determination of the streptophage susceptibility of the isolates one of the most odourous streptomycete species(USC-14510)was selected to be tested further using different pond simulations resembling real-life *** was tested as the indicator of off-flavour taint production and as it has been previously reported that the cyanobacteria-actinomycete interactions occurring in ponds result in even greater levels of geosmin and 2-methylisoborneol,the geosmin levels for the isolate in the presence of cyanobacteria and streptophages were also *** indicated that the highly odourous Streptomyces species(USC-14510)once infected with streptophages,can lose its capacity to produce off-flavour *** simulation studies also revealed geosmin production
