Samples of this species were taken from Moomin Creek
75 km east of Collarenebri (105) and in the Coleambally
Canal and west along the Murrumbidgee River (21). They
ranged from 218 to 444 mm in length and 85 to 1070 g in
weight. The mean weight and length of males and females
in the sample was 244g and 275 mm, and 289g and 287mm
respectively (Table 3). The length weight curves for males
and females (Fig. 25) are similar and are not significantly
different, but plots do suggest large males above 300
mm may be heavier at a given length than females.
Confirmation of this is required from large fish. The length
weight relationships are listed by Bishop et al. (2001) from
the Alligator River NT (Caudal fork length (CFL) in cm,
W in g) as W=0.012CFL3.32, n=845, r2
=1.0, by Harris and
Gehrke (1997) from inland NSW (CFL in mm, w in g) as
W=0.862x10-5CFL3.1227 and by Arthington et al.(1992b)
from the Burnet River Queensland (Standard length (SL)
in cm, W in g) as W=0.017SL3.113, n=1223, r2
= 0.964.
The exponent from inland fish in this study for all fish is
3.3403 based on total length, which is slightly higher than
reported by other workers..
