Tilapia control methods and their effectiveness

Two species of tilapia, Mozambique tilapia (Oreochromis mossambicus) and the black mangrove cichlid or spotted tilapia (Tilapia mariae), are becoming significant pests in many waterways in tropical and sub-tropical Australia. Numbers of both species have increased and they have spread significantly since their introduction during the 1970s and 1980s due to natural and human-assisted (whether […]

Carp weaknesses & vulnerabilities

Knowing your enemy is important to any defence strategy, including the management of invasive fish species. Analysis of the biology of the species is therefore an essential part of an integrated pest management plan. A lot is known about the biology and population structure of carp in Australia and certain stages in its life cycle […]

Pathways to adoption of Cyprinid herpesvirus 3 as a biological control agent for carp in Australia

This report outlines the approval process required  for Cyprinid herpesvirus 3 (CyHV-3) to be used as a biological control agent for carp in Australia. It discusses the relevant legislation, safety and efficacy assessments, registration process and recommendations. There are a number of statutory processes that need to be satisfied to obtain approval for the release […]

Feral pig

Matrix showing the relative humaneness of feral pig control methods. The ‘humaneness’ of a pest animal control method refers to the overall welfare impact that the method has on an  individual animal. A relatively more humane method will have less impact than a relatively less humane method. (Sharp and Saunders, 2008) has been developed under […]

Rapid response to new fish incursions

Some introduced freshwater fish species have had devastating impacts on Australia’s native freshwater fish species and other aquatic life and ecosystems. Introduced or ‘alien’ fish usually have a high rate of reproduction, broad environmental tolerances, and are difficult to manage. Prevention, preparedness, and incident response activities, (including quarantine/border control, risk assessments, training, containment, eradication) help […]

Benefits of Rabbit Biocontrol in Australia

EUROPEAN RABBITS (Oryctolagus cuniculus) are a severe continental-scale threat to Australia’s globally important biodiversity and agriculture. The extreme sensitivity of many native plant species to rabbit damage – as few as one rabbit per hectare can impede natural regeneration – has resulted in 75 nationally threatened plant species and five threatened ecological communities being at […]

Proceedings of the National Feral Cat Management Workshop

Domestic cats (Felis catus) were brought to Australia by the first European settlers from the late 18th century and feral populations quickly established. Feral cats are now common throughout most environments in Australia, including offshore islands. Predation by feral cats is thought to have contributed to the extinction of small to medium-sized ground-dwelling mammals and […]

RAB010: Bait delivery of Rabbit Haemorrhagic Disease Virus (RHDV)

Background Rabbit haemorrhagic disease virus (RHDV) is used to minimise the impact of the introduced European rabbit (Oryctolagus cuniculus) on agricultural production and the environment. Other rabbit control methods include poisoning, warren destruction, surface harbour removal, shooting, trapping, exclusion fencing and biological control with myxomatosis. RHDV causes rabbit haemorrhagic disease (RHD), an acute, highly contagious […]
