Prawns stocked in Lake Tyers

LAST month 300,000 eastern king prawns were stocked into Victoria’s Lake Tyers to improve recreational fishing opportunities. It is the first time that prawns have ever been stocked into a Victorian water.

The project was funded entirely by recreational fishing licence fees.

The first batch of 300,000 prawn larvae were released in February with another million prawn larvae expected to be released in October 2013.

Lake Tyers was identified as an ideal candidate for prawn stocking based on its environmental and physical attributes through consultation with researchers, anglers and other government agencies.

Prawn stocking in estuaries elsewhere along the south-eastern NSW coast successfully improved fishing opportunities. Fisheries Victoria believes similar results can be achieved at Lake Tyers.

Lake Tyers will be temporarily closed to commercial bait fishing until 31 January 2014 to allow the stocked prawns to grow and be available to recreational fishers.

The release of these prawns is accompanied by a monitoring program to determine how the prawn larvae survive and contribute to the fishery.

The monitoring program will help us understand the environmental conditions favourable for stocking and clarify the contribution that the released prawns make to the overall population in Lake Tyers.

Researchers, with the help of recreational anglers, will differentiate the stocked prawns from wild ones that naturally occur in the lake through genetic profiling.

Hopefully, anglers can look forward to great prawn fishing at Lake Tyers towards Christmas 2013 when the first 300,000 prawn larvae will reach a table size of around 10 cm.

Fisheries Victoria will assess the success of this project to inform further marine stocking endeavours of this kind, which may include marine and estuarine fish species.
