� Administer all prescribed medications and therapeutants under the strict guidance and<br />
authorisation of the Principal Veterinarian or Senior Fish Pathologist at the WA Fish Health<br />
Laboratories;<br />
� Keep comprehensive records of all prescribed and non-prescribed medications and<br />
therapeutants applied to fish on the aquaculture site including groups medicated, dose<br />
rates and duration; and<br />
� Maintain comprehensive record of all management responses, including alterations to fish<br />
husbandry practice, relating to observation of signs of disease.<br />
8.3 Risk assessment<br />
The risk assessment was conducted in consultation with DoF using the analysis tool outlined<br />
in the National ESD Framework for aquaculture (Fletcher et al. 2004, vom Berg 2008). The<br />
component tree used for identifying potential environmental effects of fish farms, and<br />
findings of the risk assessment are detailed in Appendix A. The risk assessment is used to<br />
evaluate commonly perceived risks of environmental impact that may result from marine<br />
farm operations. The environmental risks identified in this risk assessment were derived<br />
from:<br />
� The component trees outlined in Fisheries Management Paper 229 (vom Berg 2008);<br />
� Concerns arising from public and stakeholder consultation; and<br />
� Report and Recommendations of the OEPA (2008).<br />
The main aim of the risk assessment is to determine if the proposed management is<br />
sufficient, and the management strategies to be considered in determining consequence and<br />
likelihood levels (vom Berg 2008). Figure 8.1 provides an overview of the risks associated<br />
with sea-cage aquaculture as summarised in vom Berg (2008). The risk matrix and risk<br />
matrix outcomes are provided in Table 8.1 and Table 8.2. Results of the risk assessment are<br />
shown in Table 8.3.<br />
