Atlantic salmon the hard way

Atlantic salmon the hard way

Scott McDonald
The first Atlantic salmon eggs used to begin Tasmania's Atlantic salmon aquaculture industry were introduced into Tasmania in 1984. From these humble beginnings a valuable Tasmanian industry has evolved with a worldwide reputation for having a premium disease free product. This industry provides a spin off to all anglers in the form of regular escapes of salmon from the farms.

fisheriesParalytic shellfish toxin (PST) levels in lobster samples collected last week from the Central East and Maria Island rock lobster biotoxin management zones are still very high and well in excess of the regulatory limit of 0.8mg/kg. The highest results were 7.1 and 5.5 mg/kg. Whilst this is a decrease from the peak levels recorded 5 weeks ago (30 October), a much greater reduction will be needed before the zones can be re-opened for fishing.

The algal bloom is continuing to persist around the lower east coast, which is likely to slow the rate at which lobsters can flush out the toxin. Data from previous blooms, as well as the current event and research tank trials, suggests that even when the bloom has disappeared, it is unlikely that lobsters in these zones will return to acceptable levels within a month, given the latest PST results.
Accordingly, it is planned to re-sample lobsters from these zones around 15 January (5 weeks from the previous sample collection).
Lower East Coast Zone is closed pending results
Lobster samples from the Lower East Coast zone are at the Laboratory in Sydney for analysis. The results are anticipated late on Monday 18th December 2018.
