DAWSON RIVER BARRAMUNDI: SCLEROPAGES LEICHHARDTIH. 47 
on 21st October, 1922, shot with a rifle several Barramundi, 
the mouth of one of which was full of ova in various stages of 
development. 
The best method to follow in securing ova and young forms 
would be to find a suitable spot on the Dawson to drag a net ; 
a strong hemp net of three-inch mesh about fifty yards in length, 
with wings ten feet deep and a bunt eighteen feet, would, in 
my opinion, be the most suitable. 
The facts so far obtained might be shortly expressed 
thus :— 
1. Barramundi carries the spawn in its mouth. 
bo 
October is the spawning season. 
Fish when meshed eject the spawn. 
a 
Sexually mature fish are not meshed in a net of’ 
three-inch mesh. 
OL 
Fish secured in the bunt of a drag-net would 
retain the ova and young fish in their mouths. 
On 12th November, 1922, whilst dragging a net in the 
Burnett River, a Salmon Catfish, Hexanematichthys australis, 
was taken with ova in its mouth. This fish is uncommon in the 
Burnett but extremely plentiful in the Dawson River; the 
latter river would be the place to go if ova of this fish were 
required.
