A total of 806 non-native ornamental fish species are (at the time of this study) contained in the grey list of potentially noxious fish species in Australia. As part of the national strategy, all species on the grey list are to be allocated a potential preliminary risk rating. O...
This report describes the patterns of relative biomass and population structure of pipi (cockle, Donax deltoides) on the Younghusband Peninsula and assesses the potential for using fishery-independent surveys to monitor stock status. The study was initiated following an agreement...
Environmental water provisions (EWPs) have been planned for Onkaparinga River since 2006 but the delivery of planned environmental flows was delayed indefinitely due to drought. Increased rainfall in spring 2009 resulted in surplus water in Mount Bold Reservoir which had been fil...
The decline in tree (Eucalyptus camaldulensis and Eucalyptus largiflorens) condition in recent years on the Chowilla Floodplain has become a major concern for managers of the system. Recognition of this issue led to a trial watering of a small flood runner on Monoman Island in sp...
We analysed a 25 year time-series of fishery catch and effort data, and age/size information for four large-bodied, native fish species to investigate the hypotheses, that under conditions of reduced freshwater inflows and high fishing pressure: (i) the structure of fish assembla...
As a result of the combined affect of the over-abstraction of water from the Murray-Darling Basin (MDB) and persistent drought conditions in south-eastern Australia, inflows in the South Australian MDB have been below average for over five years. Consequently, water levels in man...
Condition Monitoring Plan for the Coorong, Lower Lakes and Murray Mouth Icon Site (Maunsell Australia Pty Ltd. 2009) identifies that a monitoring program is required that focuses on measuring the key environmental parameters that are indicators of river and floodplain health in b...
Lake Albert is part of the Coorong, Lower Lakes and Murray Mouth Ramsar wetland. It was disconnected from Lake Alexandrina via an earthen levee in March/April 2008 to minimise evaporative water losses during drought conditions that have persisted since at least 2002. However, dec...
A Code of Practice (CoP) for Threatened, Endangered and Protected Species (TEPS) has previously been shown to be successful in mitigating the operational interactions of the Australian Sardine Fishery (SASF) with the short-beaked common dolphin (Delphinus delphis). Encirclement a...
