“…For example, one of the lowest claimed success rates from the current review was for translocations at 57%. This is still considerably higher than documented for freshwater fish internationally (,30%), although data are scarce (Hendrickson and Brooks 1991;Sheller et al 2006). The high rate claimed in the current review possibly is inflated by the initial 'success' of survival after translocation, but which ultimately may fail to establish self-sustaining populations.…”

Abstract. Freshwater fish are a highly threatened group and recovery of these threatened species is an increasingly difficult ecological and social challenge. There are many different on-ground recovery actions available to managers, but no synthesis of what, how or why these recovery actions have been deployed. The present paper reviews 428 reported on-ground recovery actions from a survey of practitioners of threatened freshwater-fish recovery in Australia. Recovery actions were grouped into 12 categories, with the most commonly utilised recovery categories being harvest control, translocation, habitat enhancement and stock enhancement. Major drivers of recovery actions were general conservation concern, recovery plans and emergency responses. The number of recovery actions grew significantly in the decade beginning 2000 as the impacts of prolonged drought in south-eastern Australia intensified. In all, 58% of recovery actions occurred in the Murray-Darling Basin, although this region holds only 27% of the 74 listed threatened freshwater fish in Australia. Few or no recovery actions were reported for many species, and few actions occurred in northern or western parts of the country. More than 80% of recovery actions reportedly had some form of monitoring. The diversity of management interventions is reviewed, and patterns and issues are identified to guide future recovery efforts.

“…Some actions can be taken to minimize changes between translocated and donor populations. Effects of a small founding population such as founder bottlenecking and genetic drift, can be avoided by introducing an effectively large number of individuals over time, with associated monitoring (Hendrickson and Brooks, 1991;Stockwell et al, 1996). A translocation site can be chosen that resembles as closely as possible the donor site in physical and biotic factors, minimizing the effects of differential selection.…”

“…However, translocations into existing populations of the same species may encounter problems when local populations are genetically distinct or locally adapted (Gharrett and Smoker, 1991;Leary et al, 1995). Translocation may also be used to form new populations, either to re-establish the species where it has become locally extinct, or to form refuge populations in order to form a numerical buffer to extinction (Hendrickson and Brooks, 1991;Maitland and Lyle, 1992). However, there are good theoretical reasons to suggest that new populations established using translocation as a tool may not exactly replicate the features of the donor population.…”

“…Translocation is likely to become more commonly used as a conservation tool as existing populations are threatened in response to impacts such as climate change, or as formerly degraded habitats are restored (Hendrickson and Brooks, 1991;Maitland and Lyle, 1992). The implications of this conservation measure for conservation aims thus warrant investigation.…”

ABSTRACT1. The establishment of refuge populations has become a common management tool for threatened fish species in recent years, yet the effects of translocation are not fully understood in a conservation context.2. This paper examines the hypothesis that phenotypic changes have occurred during the formation of two refuge populations of the nationally rare powan (a freshwater fish species) which were established in Loch Sloy and Carron Valley Reservoir in Scotland.3. Significant differences in head morphology, size and growth between the founder and refuge populations and between the two refuge populations were demonstrated. These changes are probably due to a combination of founder effects, intense selection and phenotypic plasticity. These changes can undermine the rationale behind the establishment of refuge populations.4. The results call into question the usefulness of translocation as a conservation measure; however, there are times when this is the only viable management option available. The future of translocation and the validity of establishing refuge populations for powan conservation are discussed.

“…Conservation recommendations: Four criteria must be satisfied to ensure the species no longer needs protection: (1) Present wild populations must be made secure by reducing existing and potential threats to the greatest extent possible, and population size must be stable or increasing. (2) Viable wild populations have been re-established in the most natural habitats within the native range (sensu Hendrickson & Brooks 1991). No new population will be considered established until the population has persisted for a minimun of 10 years.…”
