“…It has to be said that few papers exist in literature that study injury and mortality of fish when passing through pumps (e.g., McNabb et al 2003;Helfrich et al 2004;Baumgartner et al 2009). Unfortunately, none of these studies attempt to identify the causes of fish damage nor relate their findings to the biological criteria for fish injury as derived within the framework of the AHTS program.…”

A total of 1253 live cyprinids and eel were exposed to a centrifugal pump to study fish damage rates in a wide operating range. The observed types of injuries were consistent with a mechanical cause of damage. The measured mortality rates for cyprinids show a fair agreement with a blade strike model based on empirical data by Electric Power Research Institute. Analysis of the experiments with eel led to a new correlation for the blade mortality ratio for this species; lethal injury rate is shown to be zero up to a strike velocity of 8 m·s -1 and increases linearly to 42% for a strike velocity of 15 m·s -1 . Use was made of video recordings that provided valuable information on the orientation and distribution of fish approaching the impeller. Results are presented using a new method to visualize fish mortality from a pump in its entire operating range using graphs of pressure head versus flow rate. The theory of pump hydrodynamics is used to derive a method to scale results of fish damage rate, obtained either by a model or by experiments, to different pump sizes, shaft speeds, or fish lengths. This will prove essential for a valid interpretation of pump experiments with fish.

“…Until the lethal and sub-lethal effects of screen contacts are better understood for Murray-Darling Basin species, it is advisable that approach velocities not exceed 0.1 m.sec −1 , to ensure much lower contact rates for juveniles and fish smaller than 150 mm. As larval fish are also vulnerable to entrainment at diversions in large numbers [8], [9], [21], but were not studied here, further research into their survival at fish screens is also warranted.…”

“…Mechanical injury and death can occur to fish that pass through diversion structures such as pumps and regulators [8], although many individuals do manage to survive diversion and form viable populations in off-river canals and impoundments [8], [9]. However, once diverted from the river there is seldom return passage and fish are lost from natural river populations [8], [10].…”

Fish screens can help prevent the entrainment or injury of fish at irrigation diversions, but only when designed appropriately. Design criteria cannot simply be transferred between sites or pump systems and need to be developed using an evidence-based approach with the needs of local species in mind. Laboratory testing is typically used to quantify fish responses at intake screens, but often limits the number of species that can studied and creates artificial conditions not directly applicable to screens in the wild. In this study a field-based approach was used to assess the appropriateness of different screen design attributes for the protection of a lowland river fish assemblage at an experimental irrigation pump. Direct netting of entrained fish was used along with sonar technology to quantify the probability of screen contact for a Murray-Darling Basin (Australia) fish species. Two approach velocities (0.1 and 0.5 m.sec−1) and different sizes of woven mesh (5, 10 and 20 mm) were evaluated. Smaller fish (<150 mm) in the assemblage were significantly more susceptible to entrainment and screen contact, especially at higher approach velocities. Mesh size appeared to have little impact on screen contact and entrainment, suggesting that approach velocity rather than mesh size is likely to be the primary consideration when developing screens. Until the effects of screen contacts on injury and survival of these species are better understood, it is recommended that approach velocities not exceed 0.1 m.sec−1 when the desire is to protect the largest range of species and size classes for lowland river fish assemblages in the Murray-Darling Basin. The field method tested proved to be a useful approach that could compliment laboratory studies to refine fish screen design and facilitate field validation.

Abstract. Recovery of threatened species is often necessarily a long-term process. The present paper details the progress towards the recovery of trout cod, Maccullochella macquariensis, an iconic, long-lived fish species first listed as threatened in the 1980s. The objectives, actions and progress over three successive national recovery plans (spanning 18 years) are assessed, documenting changes to population distribution and abundance and updating ecological knowledge. Increased knowledge (especially breeding biology and hatchery techniques, movements, habitats and genetics) has greatly influenced recovery actions and the use of a population model was developed to assist with management options and stocking regimes. Key recovery actions include stocking of hatchery-produced fish to establish new populations, regulations on angling (including closures), education (particularly identification from the closely related Murray cod, M. peelii) and habitat rehabilitation (especially re-instatement of structural woody habitats). In particular, the establishment of new populations using hatchery stocking has been a successful action. The importance of a coordinated long-term approach is emphasised and, although there is uncertainty in ongoing resourcing of the recovery program, much has been achieved and there is cautious optimism for the future of this species.
