Eastern freshwater cod

Recovery Plans and Threat Abatement Plans have been subsequently developed for threatened species trout cod (Douglas et al., 1994), Mary River cod (Simpson and Jackson, 1996), silver perch (Clunie and Koehn, 2001 Anon., 2006) and eastern freshwater cod (NSW Fisheries, 2002 Talbot et al., 2004). There have also been a number of pubhshed reviews and case... 

Conservation of eastern freshwater cod was the first such programme in Australia. A key priority was to increase the distribution in the Clarence River System and to establish a self-maintaining population in the Richmond River System (Rowland, 1985b, 1988a Ingram et al., 1990). In 1988 and 1989, a total of 29000 fish produced at the Eastern Freshwater Fish Research Hatchery was stocked at selected sites in both the Clarence and Richmond systems (Rowland, 1990). Subsequently, between 1997 and 2002, approximately 300000 fingerlings, produced at a commercial hatchery...
