The Environment and Sustainable Development Directorate are letting us know about their cod encouraging reef balls:
“Over the past 10 years Yerrabi Pond has been stocked with over 50,000 native fish to help improve the health of the waterway and assist recreational fisherman to enjoy the pond.
“The site is a popular spot amongst local fishermen. However; monitoring has shown that the Pond seems to lack large numbers of larger cod despite having good numbers of small cod under the legal minimum size limit of 60 cm.
“These reef balls will give the larger cod somewhere to live and the smaller cod somewhere to grow and develop over time, creating a healthy, sustainable population in the pond,” Mr Beitzel said. This is the second reef ball project in the ACT following the Murray Cod breeding balls in the Molonglo River. The ACT Government will monitor the pond as part of its regular fisheries monitoring program.
