NOT even the wet weather and cool change could stop St George Fishing and Restocking Club members from performing their annual duty at the weekend.
About 40,000 yellowbelly and 10,000 silver perch were released throughout parts of the Balonne River.
Ordinarily Murray cod are released as well, however the supplier was out of stock.
The club hopes to release Murray cod at next year's restock, as the fish can grow to 45kg.
It is hoped 50 per cent of the released fingerlings will mature to adulthood.
The lack of water and feed and the prevalence of carp throughout the Balonne river system causes a 50 per cent mortality rate.
The club purchases the fingerlings from the profits and proceeds of its annual fishing competition in October
Club president Warren Whitaker thanked sponsors for their support with the release and their ongoing support throughout the year.
"Without that support, the event would not be possible,” he said.
"And thank you to all who assisted in the release.”
