Additional threats include habitat degradation from pollution and eutrophication, along with overfishing and destructive fishing practices.

Luciogobius albus

Luciogobius albus faces severe threats from habitat degradation caused by urban development, agricultural expansion, and water pollution in its limited freshwater range. Dam construction and water diversion projects have disrupted natural flow patterns essential for the species' survival. Invasive species introduction has created additional competitive pressure and predation risks for remaining populations.

Haplochromis crocopeplus

Haplochromis crocopelius faces severe threats from the introduced Nile perch, which preys heavily on native cichlid species. The species is also impacted by declining water quality due to pollution, eutrophication, and sedimentation from agricultural activities around Lake Victoria. Overfishing and destructive fishing practices further pressure the remaining population.

Pachytriton wuguanfui

Proterorhinus tataricus

Mogurnda mbuta

Mogurnda mbuta faces severe threats from habitat degradation caused by water pollution, mining activities, and alterations to natural river flow patterns. The introduction of non-native fish species and limited geographic distribution further compound the risks to this endemic freshwater species.

Mugilogobius amadi

Mugilogobius amadi faces severe threats from habitat degradation and loss caused by human development, agricultural expansion, and water pollution in its limited Indonesian range. The species' extremely restricted distribution makes it highly vulnerable to local environmental changes and catastrophic events.

Mogurnda furva

The Northern Trout Gudgeon faces severe threats from habitat degradation caused by agricultural runoff, urban development, and water extraction. Invasive fish species compete for resources and prey on juveniles, while declining water quality from pollution and sedimentation further reduces suitable habitat. Climate change compounds these pressures through altered rainfall patterns and extreme weather events that destabilize stream ecosystems.

Mogurnda vitta

The chequered gudgeon faces severe threats from habitat degradation caused by agricultural runoff, urban development, and water extraction. Competition and predation from introduced species, combined with altered river flows from dam construction, have further reduced population viability.

Percina jenkinsi

The Conasauga logperch faces severe threats from habitat degradation caused by sedimentation, agricultural runoff, and stream channelization within its limited range. Water quality deterioration and altered flow regimes from human activities have significantly reduced suitable habitat. The species' extremely restricted distribution makes populations highly vulnerable to localized environmental disturbances.

Ctenodesma borneensis

Betta burdigala

Betta burdigala faces severe threats from habitat destruction caused by deforestation and conversion of peat swamp forests for agriculture, particularly palm oil plantations. Water pollution and drainage of wetland areas further degrade the acidic, shallow water environments this species requires for survival.

Labeo fisheri

Allomogurnda flavimarginata

Allomogurnda flavimarginata faces severe threats from habitat degradation caused by deforestation, agricultural runoff, and mining activities that compromise water quality in its native river systems. Urban development and infrastructure projects have fragmented and destroyed critical freshwater habitats. Climate change further threatens the species through altered precipitation patterns and temperature changes that disrupt aquatic ecosystem balance.

Ilex servinii

Ilex servinii faces severe threats from habitat loss and degradation caused by human activities including land conversion and agricultural expansion. The species' extremely small population size and restricted distribution make it highly vulnerable to extinction from both environmental pressures and random demographic events.

Gonystylus spectabilis

Kimberleyeleotris notata

Kimberleyeleotris notata faces threats from habitat degradation caused by agricultural activities, water extraction for mining and pastoral operations, and potential impacts from invasive species. Climate change poses additional risks by altering rainfall patterns and increasing extreme weather events that could disrupt the seasonal water cycles essential for the species' survival.

Polysteganus undulosus

Parambassis altipinnis

Parambassis altipinnis faces severe threats from habitat degradation caused by agricultural runoff, urban development, and water pollution in its freshwater river systems. Dam construction and water extraction have altered natural flow patterns, while collection for the aquarium trade may add additional pressure on wild populations.

Competition and predation from introduced fish species have significantly impacted native populations. Water extraction and quality degradation in key catchments continue to reduce available suitable habitat.

Gonystylus nervosus

Endiandra rhizophoretum

Acipenser gueldenstaedtii

Russian sturgeon face severe pressure from overfishing driven by the valuable caviar trade, with illegal poaching remaining a persistent problem despite regulations.
