Silver perch jumping frenzy captured by James Walker at Longreach

The sight of dozens of silver perch, some fully grown, throwing themselves up into the stream of water running into a dam captured by Longreach grazier James Walker has become a social media sensation.

Like a fast-paced basketball game the black bream were launching themselves towards the muddy flow, some hitting the banks of the dam and tumbling back into the water, and a rare few scoring the bulls-eye of the cement pipe.

"I have seen fish jump up the fluming before but not to that extent," James said. "There was a piranha-like frenzy about it all."

He said that prior to Monday's flow the dam the fish were in didn't have much water left and a population of pelicans had settled in for an easy feast.

"The fish might have been thinking, get me out of here," James joked.

He was on hand to capture the fish on the fly because he'd had to dislodge a pile of debris in the dam's backwater that was preventing the water from going into the dam and so was able to see the reaction it caused when it began flowing.

Yabbies and freshwater crabs were enjoying the sensation too.

According to Fishing World, silver perch or black bream are closely related to Welch's grunter, a native of the Lake Eyre drainages and the Barcoo, Diamantina and Georgina Rivers.

They're highly migratory, moving upstream during river flow events, with movements of tens to hundreds of kilometres commonly recorded.

"They wouldn't have got far trying to jump out of my dam," James said. "All jokes aside, it's just a joy to see running water."

He has had 250mm in two separate falls, in early February and again at the end of March and said all his dams are now full.

While annual grass and herbages are growing well, he said perennial grasses still had a way to go, and he would continue to keep Camden Park at 20 per cent stocked.
