Anaesthetics are used in Tassal’s<br />
marine and freshwater operations in the<br />
following instances:<br />
• Fish sampling for weight check, AGD<br />
check and non-lethal samples<br />
• Euthanising fish in freshwater<br />
operations when there are large<br />
numbers of fish that require culling or<br />
are moribund, and<br />
• General handling, for example,<br />
grading in freshwater.<br />
The anaesthetic we use is Aqui-S<br />
(isoeugenol), which is a registered<br />
product that requires no withdrawal<br />
period. Tassal has an internal fish<br />
anaesthesia protocol for using Aqui-S<br />
to ensure that all fish are anaesthetised<br />
safely. This protocol includes<br />
requirements around preparations<br />
and monitoring of fish as well as<br />
physiological considerations to take into<br />
account when using.<br />
Biosecurity<br />
Biosecurity refers to a set of measures<br />
put in place to minimise the risk of<br />
disease outbreaks and to prevent<br />
the spread of any disease which may<br />
occur. Tassal has a legal obligation and<br />
duty of care to our stock and to other<br />
aquaculture operators to ensure all<br />
possible biosecurity measures are in<br />
place.<br />
Tassal operates within the Tasmanian<br />
State Biosecurity Plan, and our farming<br />
operations span across two very<br />
distinct biosecurity zones. Tassal has<br />
an internal farm disease management<br />
and biosecurity protocol and fish health<br />
management plans are in place for the<br />
south east and Macquarie Harbour.<br />
These plans include measures to avoid<br />
the introduction of new and/or exotic<br />
diseases and to limit the spread and<br />
impact of diseases.<br />
The Tasmanian Salmonid Growers<br />
Association (TSGA) Biosecurity<br />
Management Plan is currently in<br />
development with industry members.<br />
Tassal’s Business Intelligence<br />
supporting Fish Health<br />
A key project for marine operations was<br />
the development of a tool to assist in the<br />
management of Amoebic Gill Disease<br />
(AGD). This combines field data with<br />
modelling from our Selective Breeding<br />
Program (SBP) to deliver a user friendly<br />
interface that can be used to track<br />
disease progression, prioritise on-farm<br />
activities and review the efficacy of<br />
management strategies.<br />
