Bothriocephalus acheilognathi was collected from 13 of 38 carp (Cyprinus carpio), 2 of 4 mosquito fish (Gambusia holbrooki), and 2 of 12 western carp gudgeon (Hypseleotris klunzingeri ) in waterways of the Australian Capital Territory and New South Wales. This is the first record of this parasite in Australia, and its presence in H. klunzingeri is a new host record. B. acheilognathi presumably arrived in Australia with its introduced fish hosts and has since crossed into native fishes. This cestode may infect other native fish species, a potential that is significant given the high pathogenici

Per- and poly-fluoroalkyl substances (PFASs) are persistent organic pollutants that have been extensively used in commercial and industrial applications, such as aqueous film-forming foam (AFFF) formulations. Widespread use of AFFFs has led to an increasing number of reports documenting PFAS contamination around civilian and military airports. However, research on the presence and distribution of PFASs in Australia is lacking. This study presents the first report of PFASs in Australian native and introduced freshwater species, sampled from a watercourse adjacent to the regional airport and col

AbstractThere is a paucity of information on the diversity and occurrence of freshwater fish parasites in Australia. This study investigates the distribution and occurrence of a parasitic nematode of the genusContracaecumin freshwater fish from south-eastern Australia. Fish (n= 508) belonging to nine species and eight families were collected from eight wetlands associated with the Murrumbidgee River floodplain in the southern Murray–Darling Basin and subjected to laboratory examination. Third-stage nematode larvae were found in eight of the nine fish species. The exception was the fly-specked

Karyotypic data from Australian native freshwater fishes are scarce, having been described from relatively few species. Golden perch (Macquaria ambigua) and Murray cod (Maccullochella peelii) are two large-bodied freshwater fish species native to Australia with significant indigenous, cultural, recreational and commercial value. The arid landscape over much of these fishes’ range, coupled with the boom and bust hydrology of their habitat, means that these species have potential to provide useful evolutionary insights, such as karyotypes and sex chromosome evolution in vertebrates.

Upstream migration of juvenile stages of temperate Australian amphidromous fish typically coincides with seasonally low river discharge when hydraulic (e.g. cascades) and physical (e.g. rock bars) barriers may be common. The ability to ‘climb’ or ‘jump’ may be expected to assist in negotiating low-flow barriers; however, it is presumed to be limited to a few native Australian freshwater fishes.

Freshwater systems offer important opportunities to investigate the consequences of intrinsic biological and extrinsic environmental factors on the distribution of genetic variation, and hence population genetic structure. Drainages serve to isolate populations and so preserve historical imprints of population processes. Nevertheless, dispersal between and within drainages is important if the biology of the species confers a good dispersal capability.

Abstract .—The Murray–Darling basin (MDB) in southeastern Australia, covers 1.1 million km2, involves six partner jurisdictions with a myriad of different government agencies, and, hence, provides an excellent example of the complexities of multijurisdictional management across a range of social and political tiers. In the MDB, fish and fisheries compete for water with agriculture, which is the traditional water user and is driven by national economics. Murray–Darling basin rivers are now highly regulated and generally in poor health, with native fish populations estimated to be at only about 10% of their pre-European settlement abundances. All native commercial fisheries are now closed, and the only harvest is by a recreational fishery. The six partner jurisdictions developed a Native Fish Strategy (NFS) to rehabilitate native fish populations to 60% of pre-European settlement levels after 50 years of implementation by addressing priority threats through a coordinated, long-term, whole-of-fish-community (all native fishes) approach. As there are a wide range of stakeholders, broad engagement was needed at a broad range of government and community levels. The NFS funding was discontinued after 10 years, not because of its lack of successes or project governance, but due to jurisdictional political changes and funding cuts that resulted in a failure of the collaborative funding structure. The withdrawal of considerable funding by one jurisdiction led to collective decline in monetary contributions and posed a threat to the multijurisdictional structures for both water and natural resource management (NRM) within the MDB. As a consequence, there was a review and reduction in NRM programs and a subsequent reduction in focus to the core business of water delivery. Reflection on the NFS, however, provides some useful insights as to the successes (many) and failures (funding) of this partnership model. Overall, the strategy and its structure was effective, as exhibited by an audit of outputs, outcomes, and networks; by the evident ongoing advocacy by NRM practitioners and the community; and by the continuation of ideas under other funding opportunities. This has provided a powerful legacy for future management of fishes in the MDB.

Abstract.—Native fish conservation areas in the Chihuahuan Desert of Texas were identified and designated as part of a statewide network of focal watersheds uniquely valued in preservation of Texas freshwater fish diversity. Native fish conservation areas represent a holistic, multispecies, and habitat-based approach to native fish conservation that encourages and facilitates coordination among landowners, nongovernmental organizations, state and federal agencies, universities, and local governments to achieve landscape-scale conservation within focal watersheds. This approach to native fish conservation provides an effective method for addressing the common nature and magnitude of threats facing species and their habitats in freshwater systems. Desert fishes and their habitats are particularly susceptible to habitat alteration, especially anthropogenic land use and water consumption patterns, which continue to create conservation challenges. The strategic and science-based conservation strategies embodied by the native fish conservation areas approach represent an innovative path forward for addressing the conservation needs of native fishes and their habitats in the Chihuahuan Desert of Texas. In this chapter, we describe six native fish conservation areas designated within the Chihuahuan Desert of Texas and profile multiagency conservation planning and delivery that has substantially increased the scope and scale of conservation investments for restoration and protection of native fishes and their habitats in the region.

Abstract.—Native fish conservation areas (NFCAs) are watersheds where management emphasizes proactive conservation and restoration for long-term persistence of native fish assemblages while allowing for compatible uses. Native fish conservation areas are intended to complement traditional fisheries management approaches that are often reactive to population stressors and focused on single-species conservation efforts rather than complete assemblages. We identified potential NFCAs in the upper Snake River basin above Hells Canyon Dam using a process that ranked all subwatersheds (Hydrologic Unit Code 12) and used empirical data on distribution, abundance, and genetics for three native trout species (Bull Trout Salvelinus confluentus, Columbia River Redband Trout Oncorhynchus mykiss gairdneri, and Yellowstone Cutthroat Trout O. clarkii bouvieri, including the fine-spotted form) and both known occurrences and modeled potential distributions of native nongame fishes. Rankings also incorporated drainage network connectivity and land-protection status (e.g., national park, wilderness). Clusters of high-ranking subwatersheds were identified as potential NFCAs that were then classified according to the presence of nongame fishes identified as species of greatest conservation need in state wildlife action plans. The Pacific Creek and Goose Creek watersheds ranked high in the upper basin (above Shoshone Falls), and Little Jacks Creek and Squaw Creek ranked high in the lower basin. We then contrasted characteristics of a select few potential NFCAs, discuss the practical implementation and benefits of NFCAs for both fishes and other aquatic species in the upper Snake River basin, examined how the NFCA approach could enhance existing conservation partnerships, and discuss how designating select watersheds as NFCAs can create higher public awareness of the value of native fishes and other aquatic species and their habitats.

Abstract.—Efficient conservation can require making strategic decisions across large landscapes. For example, two fish habitat partnerships—the Desert Fish Habitat Partnership and the Western Native Trout Initiative (WNTI)—fund conservation and restoration projects across the western United States. The Desert Fish Habitat Partnership alone serves 11 states and nearly 180 native fish species, and the Western Native Trout Initiative covers 21 salmonid species across 12 western states. Because of the large landscapes they represent, the partnerships are using multispecies aquatic assessments developed for specific river basins to aid in conservation delivery. These assessments yield a conservation value for every catchment in a basin based on known and modeled native fish distributions (including salmonids), riverine connectivity, and threats to aquatic habitats. The conservation values are scaled between 0 (low) and 1 (high) and have been used to evaluate the landscape context of conservation projects submitted for funding through the National Fish Habitat Partnership. While assessments are complete for some basins (e.g., upper and lower Colorado basins, upper Rio Grande basin), the partnerships are currently working with additional partners to fund aquatic assessments in new geographies (e.g., Bonneville and Lahontan basins). Multispecies assessments are used in conjunction with the knowledge of field biologists to inform on-the-ground conservation across large landscapes and make conservation delivery more efficient for the many imperiled native fishes in the western United States.

Abstract.—In 2015, the Little Tennessee River basin became the nation’s first native fish conservation area. Watersheds designated as native fish conservation areas are managed for the conservation and restoration of native fish and other aquatic species, allowing compatible uses. The Little Tennessee River basin spans three states (Georgia, North Carolina, and Tennessee) and features a diversity of aquatic habitats that include high-elevation coldwater trout streams, warmwater rivers, and large human-made reservoirs. Although this basin is home to a biologically diverse aquatic community, streams have been impacted by a host of stressors, including logging, dams, agriculture, industrial pollutants, piscicides, and development. Some streams impacted in the past now offer restoration opportunities, and numerous efforts are underway to restore native fish and mussels to streams in the Great Smoky Mountains National Park, on U.S. Forest Service land, on the Qualla Boundary of the Eastern Band of Cherokee Indians, and on private lands. More than 20 organizations, including federal and state agencies, industry, and nongovernmental entities, form the Little Tennessee Native Fish Conservation Partnership. The partnership supports work already underway by partners by providing additional funding, technical and educational resources, and a mechanism for collaboration. Perhaps most importantly, the partnership provides a forum to plan and implement watershed conservation on a landscape scale. Partners developed an online conservation mapper, which houses data, maps threats, identifies focal areas for restoration and protection, and ultimately serves as a conservation plan for the watershed. Current efforts to identify habitat restoration and protection projects are underway.

Abstract.—Texas harbors 191 species of native freshwater fishes, 48% of which are considered imperiled. The primary cause of fish species imperilment in Texas is anthropogenic alteration of freshwater systems, which continues to occur at rates and scales that threaten the long-term resiliency of freshwater habitats, species, and ecosystems. Innovative conservation approaches are needed to restore and maintain functional watershed processes, restore freshwater habitats, and conserve native species while simultaneously supporting human needs, such as flood control, municipal and agricultural water supply, water quality protection, and water-based recreation. The need for an integrated and holistic approach to conservation of freshwater systems has been the impetus for development of the Texas Native Fish Conservation Areas Network (hereafter “Texas NFCAs Network”). The Texas NFCAs Network consists of springs, ciénegas, creeks, rivers, and associated watersheds uniquely valued in preservation of Texas freshwater fish diversity. Twenty native fish conservation areas have been designated throughout the state. These were selected based on a spatial prioritization focused on identification of freshwater systems critically important to the long-term persistence of 91 freshwater fishes considered species of greatest conservation need. Through a shared vision of collaborative stewardship, conservation partnerships have formed among nongovernmental organizations, universities, and state and federal agencies to plan and deliver actions within the Texas NFCAs Network to restore and preserve native fishes and their habitats. Furthermore, the Texas NFCAs Network has increased awareness of the ecological, recreational, and economic values of Texas freshwater systems and helped increase interest and capacity of local landowners, communities, and recreational users (e.g., paddlers, anglers) to act as advocates and local stewards of these systems. By facilitating partnership development, coordinating broad-based conservation planning, and leveraging technical and financial resources toward strategic conservation investments, the Texas NFCAs Network has served as a catalyst for collaborative, science-based stewardship of native freshwater fishes and their habitats in Texas. The Texas NFCAs Network offers a successful case study in multispecies and watershed approaches to freshwater fish conservation transferrable to other states in the United States, with particular relevance to those states that, similar to Texas, consist predominately of privately owned landscapes.

Abstract.—The Colorado River of Texas originates in the northwest portion of the state and runs southeasterly across the environmentally sensitive Edwards Plateau ecoregion, eventually emptying into Matagorda Bay on the Gulf of Mexico. The Texas Parks and Wildlife Department (TPWD) and other conservation partners have worked for decades to conserve native fishes in the river and its associated estuary. The river and its tributaries are also the major water source for millions of people, and portions of the watershed are undergoing unprecedented human population growth and a concomitant increased demand for water. Drought, which is a frequent occurrence in Texas, exacerbates these effects. Providing adequate streamflow and water quality to conserve aquatic species while still fulfilling obligations for municipal, industrial, agricultural, hydropower, and recreational water use is increasingly challenging. Since the 1980s, the TPWD has promoted water management policies in the watershed to benefit aquatic life, conducted research to maintain a sound ecological environment for fish and other aquatic taxa, provided technical guidance and financial incentives to private landowners to improve land practices that benefit water quality and quantity, and improved public access to foster increased stewardship of the river. The TPWD has also collaborated with researchers to study the potential impacts of altered hydrology on two endemic, flow-dependent fish species, Guadalupe Bass Micropterus treculii and Blue Sucker Cycleptus elongatus. Two portions of the Colorado River watershed have been identified as native fish conservation areas in part for persistence of populations of these native fishes. Outcomes from these activities are now being leveraged using federally funded research and conservation delivery programs to further advance the conservation of native fish populations and other aquatic life in native fish conservation areas of the Colorado River watershed.

Abstract.—Movement patterns of two co-occurring catadromous fishes, estuary perch Macquaria colonorum and Australian bass Macquaria novemaculeata, were investigated in a large tidal river in southeastern Australia. Nineteen estuary perch and seventeen Australian bass were captured as mature adults from the Shoalhaven River, surgically implanted with electronic transmitters and released. Forty-nine Vemco (VR2W) acoustic receivers were strategically placed throughout the river from the Tallowa Dam wall downstream to the sea (a distance of 75 km). Between September 2007 and February 2008, a total of 800,263 detection events were recorded with most fish detected in the middle (estuary perch) to upper (Australian bass) estuarine reaches of the river. Both species made extensive use of the estuary, with no estuary perch and only three Australian bass entering the freshwater, indicating that the freshwater residency phase of these catadromous fishes may not be obligatory. The data also suggests that estuary perch and Australian bass exhibit high site fidelity, which, along with their large scale movements may be influenced by factors such as river discharge and prey availability. This large freshwater-estuarine telemetry array combined with critical abiotic information (river discharge and salinity) has and will provide a greater understanding of catadromous fish movement, particularly in relation to habitat utilization and environmental flows.

Herons and egrets commonly cause damage at aquaculture facilities and recreational fishing waters where fish are held at high densities. Fish-eating birds also can have an impact on intensively managed sport fisheries. Damage occurs when herons and egrets feed on fish purchased and released for recreational sport fishing activities. Values of these fish can be quite high given the intensity of management activities and the direct relationship of fishery quality to property value. Herons and egrets are freshwater or coastal birds of the family Ardeidae. Herons and egrets discussed in this secti
