Southern Shortfin and Longfin Eels<br />
The Longfin Eel is closely related and very similar to the Southern Shortfin Eel. However, the dorsal<br />
fin on the Longfin Eel extends well forward of the anal fin. Often incorrectly referred to as Conger<br />
Eel in Victoria and NSW they may also resemble Lampreys, especially when small.<br />
Longfin Eel<br />
Dorsal fin extends markedly<br />
forward of anal fin.<br />
Uniform olive/green to brown colour, distinctly<br />
blotched or mottled.<br />
Eastern (Freshwater) Cod, Trout Cod<br />
and Murray Cod<br />
The Eastern Cod was once common in northeastern<br />
NSW but wild spawned fish are now<br />
considered rare. Eastern Cod are similar to<br />
Murray Cod and Mary River Cod. They can<br />
vary from pale green to golden with heavy<br />
black or green convoluted mottling. The<br />
pelvic fin is clear and relatively long. The lower<br />
jaw protrudes.<br />
Trout Cod have the following features which<br />
distinguish the species from Murray Cod:<br />
Southern Shortfin Eel<br />
Dorsal fin extends a little<br />
forward of anal fin.<br />
Uniform olive/green to brown colour, no<br />
distinctive markings.<br />
Blue-grey colour with well defined dark spots<br />
and dashed markings, whereas Murray Cod are<br />
generally greenish in colour with dark marbled<br />
markings.<br />
■■<br />
The snout and upper jaw is usually longer<br />
than the lower jaw. In Murray Cod the jaws<br />
are level or the lower jaw longer.<br />
■■<br />
The forehead profile is straight or slightly<br />
convex whereas in Murray Cod the<br />
forehead profile is slightly concave.<br />
■■<br />
The snout and forehead of Trout Cod are<br />
usually clear of any markings.<br />
