The majority of the fish (identified as Maccullochella peelii n=22 and Macquaria ambigua n=2) were caught in freshwater environments during the warm season, and had grown to an age and size indicative of sexual maturity.
The relationship between otolith weight and fish length for Maccullochella peelii is: TL (mm)=(Otolith weight (g)+0.
Of these, 21 were identified as belonging to Maccullochella peelii (Murray cod) (Table 2).
Based on these 15 samples, minimum length estimates for Maccullochella peelii range from 685 to 2200mm (see Figure 2).
Whitley (1955) recorded a maximum length (TL) of Maccullochella peelii of 1800mm, and a weight of 83kg.
Those of the Maccullochella peelii fish from the Lower Murray sites show distinct variation within the species, though all were spawned in freshwater.
The large predatory Maccullochella peelii could have been caught using spears or clubs.
