FISHERS in South Australia will be banned from taking Murray Cod from the river next year to protect the freshwater species. 

With the fish dependent on water flows for reproduction, the ongoing drought is placing extra pressure on the species.

"Given the continued drought and lack of flows in the River Murray, it's important that we take strong and decisive action now to protect this iconic freshwater species for future generations," said Fisheries Minister Rory McEwen.

"It's important that the current size of the Murray cod population is maintained to ensure that spawning success and recruitment to the fishery can occur when there are improved river flows and enhanced habitat conditions."

Mr McEwen said any cod caught next year must be immediately returned to the water.
