9000 trout cod fingerlings to be released into the Macquarie River  

Nine thousand trout cod fingerlings were released into the Macquarie River above Burrendong Dam on Thursday 8 December.

The fish were bred at NSW Department of Primary Industries (NSW DPI) Narrandera Fisheries Centre.

Hatchery Manager at the centre, Matthew McLellan, said this was the third of a five-year program stocking this stretch of the Macquarie River under the ‘Species Recovery Plan’ for this threatened species. 

The NSW Government is funding the release, supported by the NSW Recreational Fishing Trusts, which are funded by the recreational fishing licence fee. 

“The fingerlings are 40mm long and have been calcein marked to allow easy identification of the stocked fish in any follow up study,” Mr McLellan said. 

A number of regional volunteers from The Central Acclimatisation Society are helping to coordinate the release of the fingerlings. 

“More than one million trout cod bred at Narrandera Fisheries Centre have been released across the State since 1991,” Mr McLellan said.

“Trout cod are endemic to the southern Murray-Darling river system, including the Murrumbidgee and Murray Rivers, and the Macquarie River in central NSW. 

“The species was once widespread and abundant in these areas, but has undergone dramatic declines in its distribution and abundance during the past century. 

“The last known reproducing population of trout cod is confined to the Murray River below Yarrawonga downstream to Tocumwal.”

Mr McLellan said the reestablishment of trout cod at a small number of locations represents positive signs for future recovery of the species. 

“Trout cod are still considered to be in danger of extinction from factors such as habitat modification and degradation, illegal fishing activities and the adverse impacts of introduced species,” he said. 

“The recovery of trout cod relies on an ongoing concerted effort by government authorities and the wider community.”

Harming trout cod is illegal so it is important that fishers can distinguish trout cod from the similar looking Murray cod

forgive my ignorance but what is 'Calciene' marking and what are it's long term impacts on the health of the fish?

Its a type of die, they put the fingerlings in a tub of it, and basically it stays in the scales for the life of the fish. Shows up under a certain light.

Not to sure how I feel about their rec fishing levee going towards funding this, unless of course the ultimate goal is to actually let people target them!

Should be funded from the Greens budget!  ;D
