“…A common theme in both marine and inland systems is that the effects of climate change on fishes are complex and often cannot be distilled into one cause and one direct effect. Temperature is often a dominant factor (see Carlson et al 2017;Henderson et al 2017;Klein et al 2017;Pratchett et al 2017), but it is not the only driving variable (see Al-Chokhachy et al 2017;Myers et al 2017;Whitney et al 2017). Also, temperature can influence fishes directly through physiological processes and indirectly through interspecific interactions (see Myers et al 2017).…”

“…Additionally, climate change often interacts with other anthropogenic stressors with unanticipated consequences (see Collingsworth et al 2017;Klein et al 2017). The resilience or adaptive ability of many species to adjust to new climate scenarios and new externalities can only be projected at this point (see Myers et al 2017). In some cases, the changes may have a positive effect on fish production (e.g., increased survival) and, in others, a negative one (e.g., reduced habitat).…”

“…Myers et al (2017) conducted a review of documented and projected climate impacts on inland fishes globally and found that research to date tended to address how temperature increases alone would affect fishes; however, studies that looked at other climate variables found that that temperature is not the only climate factor that will affect fishes in a changing climate. Al-Chokhachy et al (2017), for example, conducted a review of stream hydrologic patterns across the Greater Yellowstone Area in the United States and found that with shifts to earlier peak discharge, reduction in summer minimum stream flows, declines in duration of river ice, and decreases in total water volume, particularly during the most recent time period, are critical habitat metrics for resident salmonids.…”

“…Much is still unknown with regards to the tolerances of many fish species to changes in temperature, flow, salinity, and other environmental factors linked to climate change and their adaptive capacity to adjust to these changes. In reviewing documentation of climate change impacts on inland fishes, most of which focused on responses of salmonids in North America and Europe, Myers et al (2017) highlighted the major gaps in the literature in terms of taxonomic groups and geographic focus. Klein et al (2017), as another example, noted that for the impacts of salinity, dissolved oxygen, pH, and ocean currents on the New England groundfish fishery, there are still many more unknowns than knowns.…”

Assessing the effectiveness of protected areas for sustaining species and identifying priority sites for their conservation is vital for decision making, particularly for freshwater fishes in South America, the global centre of freshwater fish diversity. Several conservation planning studies have used threatened freshwater fishes or species that are vulnerable to climate change as conservation targets, but none has included both in priority‐setting analysis. The objectives of this study were to identify gaps in the coverage of the existing protected areas in representing the endemic freshwater fishes of the Tropical Andes region, and to identify conservation priority areas that adequately cover threatened species and species vulnerable to climate change. Data on 648 freshwater fishes from the Tropical Andes were used to identify gaps in the protected area coverage, and to identify conservation priority sites under three scenarios: (i) prioritize threatened species; (ii) prioritize species that are vulnerable to climate change; and (iii) prioritize both threatened species and species vulnerable to climate change. A total of 571 species (88% of all species) were not covered by any protected areas; most of them are restricted to ≤10 catchments. To represent both threatened species and species vulnerable to climate change in the third scenario, 635 catchments were identified as priority areas, representing 26.5% of the study area. The number of irreplaceable catchments for this scenario is 475, corresponding to 22.5% of the total area. The results of this study could be crucial for designing strategies for the effective protection of native fish populations in the Tropical Andes, and for planning proactive climate adaptation. It is hoped that the identification of priority areas, particularly irreplaceable catchments, will help to guide conservation and management decisions in the Andean region.

The Amazon basin hosts the Earth's highest diversity of freshwater fish. Fish species have adapted to the basin's size and seasonal dynamics by displaying a broad range of migratory behaviour, but they are under increasing threats; however, no study to date has assessed threats and conservation of Amazonian migratory fishes. Here, the available knowledge on the diversity of migratory behaviour in Amazonian fishes is synthesized, including the geographical scales at which they occur, their drivers and timing, and life stage at which they are performed. Migratory fishes are integral components of Amazonian society. They contribute about 93% (range 77–99%) of the fisheries landings in the basin, amounting to ~US$436 million annually. These valuable fish populations are mainly threatened by growing trends of overexploitation, deforestation, climate change, and hydroelectric dam development. Most Amazonian migratory fish have key ecological roles as apex predators, ecological engineers, or seed‐dispersal species. Reducing their population sizes could induce cascading effects with implications for ecosystem stability and associated services. Conserving Amazonian migratory fishes requires a broad portfolio of research, management, and conservation actions, within an ecosystem‐based management framework at the basin scale. This would require trans‐frontier coordination and recognition of the crucial importance of freshwater ecosystems and their connectivity. Existing areas where fishing is allowed could be coupled with a chain of freshwater protected areas. Management of commercial and subsistence species also needs fisheries activities to be monitored in the Amazonian cities and in the floodplain communities to allow assessments of the status of target species, and the identification of management units or stocks. Ensuring that existing and future fisheries management rules are effective implies the voluntary participation of fishers, which can be achieved by increasing the effectiveness and coverage of adaptive community‐based management schemes.
