This is in relation to the sex of barramundi but answers your question fairly well
"This can be due to stunted growth because of insufficient food, or it may be that a barra has been in
fresh water for an extended period and has remained male. This is the case with freshwater
impoundments such as Manton Dam here in the NT and Tinaroo Dam in Queensland, which are
stocked with barramundi. Barra that weigh over 20 kg and are over 100 cm long, which are regularly
caught at Tinaroo, are all males. Restocking therefore, is the only way to replenish barramundi
populations in freshwater impoundments. Barra probably have to be sexually active as a male before
changing to a female and can only do this in salt water."
