Identifying Introduced Fish in the MDB

Identifying Introduced Fish in the MDB

This booklet discusses the different terminology around alien species (e.g. introduced, translocated, pest, noxious) and why alien fishes are so successful in establishing and expanding their distribution. The impacts of alien fishes are discussed as well as information about how these species arrived in Australia and the reasons behind their subsequent spread.

For each of the 11 alien fish species in the Basin, and one species immediately adjacent to the Basin (Mozambique tilapia, Oreochromis mossambicus), information is presented on scientific and common names, as well as providing guidance on how to identify the fish, maximum size, lifespan, diet, habitat, environmental tolerances, invasive ecology and potential impacts. A photograph of each species is provided and the presence of each species in the Basin states and territory is included. Broad management and control techniques and principles are discussed, and information is provided on how individuals can help control alien fish.

Atlantic salmon, Salmo salar
Brook char, Salvelinus fontinalis

Implications for native fish

The book provides basic information that allows people to identify alien fish species, promotes awareness of fish conservation and highlights the major threats to native fish from alien species.
