Fish stocks in Myponga Reservoir have been boosted with more than 90,000 natives released on Wednesday, February 5.
As part of the release, 32,000 Murray cod fingerlings, 30,000 silver perch and 30,000 golden perch have found a new home in the reservoir.
Shore-based fishing was first allowed at the reservoir in December 2019 as part of the state government's plan to offer more recreational activities at reservoirs across South Australia.
Minister for Environment and Water David Spiers said it was the first major stocking at Myponga.
"Fishing is high on the list for South Australians as a requested activity at reservoirs as they open for the first time for expanded access, and it was an exciting milestone to open up Myponga for fishing just a couple of months ago," he said.
"We have carefully considered the best approach to provide recreational experiences and stocking Myponga Reservoir with more fish will make sure families and keen anglers can reel in a catch for years to come.
Mr Speirs revealed there were plans to add yearling trout in the middle of the year.
"Catching trout so close to Adelaide's CBD will be another significant drawcard for the tourism and recreational fishing sectors in South Australia, and being yearlings means the fish will be larger and available for anglers to take much sooner than traditional fingerlings," he said.
Other features of Myponga Reservoir Reserve include a 3.3 kilometre walking trail, cycling paths and picnic spots.
More than 13,600 people have visited the reserve since recreational access expanded in 2019, which Mr Speirs said had boosted the local economy.
