Third incident in weeks.
In November, the Tasmanian salmon farmer Huon Aquaculture was hit by a fire which resulted in the loss of 52,000 salmon.
ABC reports that another blaze has hit a Huon site, but the cage, at Hideaway Farm, was empty of salmon.
Jillaine Williams told the publication that she was on a boat passing Huon Aquaculture’s pens at Hideaway Bay, in southern Tasmania, when she saw the fire break out.
She filmed and uploaded the footage to Facebook on Tuesday.
“[It was] quite a large blaze, quite high flames, a metre and a half,” Williams said.
“The smoke was thick and black, [Huon] had a few vessels there, they seemed to put it out in about 15 minutes,” she added.
In a statement, Huon said that the incident was down to a “small electrical fire caused minor damage to the railing on an outer pen”.
