EPA tick for fish hatchery
TASMANIA’S environmental watchdog has given Tassal’s Central Highlands hatchery proposal the green light.
The salmon producer says the $46 million hatchery will allow it to grow larger smolt which need less time at sea to reach harvest size.
The hatchery, about 6km from Hamilton on Woodmoor Rd, will use freshwater from Meadowbank Lake.
Used water will be treated onsite before going into a dam to be used as irrigation on a neighbouring property. Fish waste will be treated to become compost.
A Tassal spokesman said the hatchery would use recirculation technology, with no water returned to the river and a small amount to irrigation.
The Environment Protection Authority said the hatchery, which will be capable of producing smolt up to 600g, will produce up to 1400 tonnes of fish each year.
EPA board chair Warren Jones said the development could be managed in an environmentally sustainable and acceptable manner – provided conditions relating to odour, noise, waste and irrigation of wastewater are complied with.
He said ongoing sampling and modelling would be required to ensure that seasonal variation and wastewater irrigation did not increase the odour risk. The proposal still needs to be approved by the Central Highlands Council.
