NO ONE is more passionate about landing a silver scaled monster than a barramundi angler.

Now that the wild barramundi season is open, Barra World Proserpine's local fishing expert Lindsay Dobe reminded anglers of bag limits and legal sizes.

"A legal wild barra is a minimum of 58cm and a maximum of 120cm. So if you catch them over 120 or under 58 you have to let them go as soon as possible in good condition and the bag limit is five fish per person,” he said.

"All barramundi are born male and they change to females around about the 90cm mark so all the big fish are females.”

Mr Dobe said that unlike fresh water impoundment, wild barramundi are an exceptional table fish.

"Though at this time of year you have to be careful because you can get the ones that have come out of the flood plains,” he said.

"We call them black or dark barra, they have been stuck up in the billabong in a fresh-water brackish environment and it doesn't make them good to eat.

"But if you get your nice shiny clean looking fish with a yellow tail, it's usually a good sign they have come from the salt.”

Lindsay said the barramundi spawn in at the mouths of creeks in the Repulse Bay area rely on the right moon phase and the correct water salinity ratio for them to spawn successfully.

The barramundi fry then head upstream into the food rich areas of the river.

"That is why Prossie has such a good barra fishery because we have massive flood plains,” he said.

Double the average rainfall in January this year will not make for great fishing this season but Mr Dobe said it would greatly advantage future fish stocks as flood water heading back to the ocean would take fish with it.

The Queensland barramundi is not the earliest fish to catch and not the easiest fish to find which is part of the obsessive attraction for many anglers.

"Plus the fact that they hit lures hard and they are a good strong fighting fish... there are a lot of ways to lose a barra, plus they jump,” Mr Dobe said.

"That is the big thing. Everyone loves seeing a barra jump and I think that is why anglers have fallen in love with barra.

"The jumping is what makes them so iconic.”

Mr Dobe said those planning to land a barra this weekend would be well advised to head to the upper reachers of the creek.

"This weekend the water is going to start dropping back a bit but right now the fish will be pushing up into those food rich creeks,” he said.

"But there will be fish caught right through the river system. The prime spots will be casting in gullies, they call it run off fishing, where the fresh is pushing out and meeting the salt. Casting into gullies at the right time of the tide is what I would be doing.”
