Any given afternoon on Awoonga can see 10 or 12 of those smaller barra caught in similar areas to where we find the larger fish. The upcoming population of these smaller barra in Awoonga is very likely to be some of the better stocking results from any previous releases. There is no lack of smaller fish.
So why would it be that we have a mass availability of 1 to 6 kg barra in a fishery that is dominated by 20 kg fish?!?!?!!??! There is no supportive evidence at Awoonga of the larger fish being detrimental to the fishery. I noted in an above post that releasing bigger fingerlings in Tinaroo(250-300mm fish) has resulted in many fish now being caught from that lake. To barra 6kg and above barramundi, 250-300mm of almost any fish species is a great size for a snack. Is it possible that there may be other reasons why stockings of smaller fingerlings in Tinaroo wasn't successful?
The bigger a barra grows, the less likely he/she is interested in eating a so called 'fingerling'!
A 20 plus kg barra is capable of eating a 5 kg barra, and a 5 kg barra is capable of eating a 1 kg barra, and that 1 kg barra is very likely to be capable of eating a 100mm fingerling and that 100mm fingerling is capable of eating a newly stocked 50mm fingerling,,,,,so,,,,AT WHAT POINT DO WE ACTUALLY DEFEAT THE PURPOSE OF STOCKING !!?!?!?!
Feedback appreciated.
