THREATENED FISHES OF THE WORLD: Cirrhinus reba (Hamilton 1822) (Cypriniformes: Cyprinidae)

The threatened Reba carp Cirrhinus reba is one of the foods high in nutritional value in Asian countries, including Bangladesh, India, Nepal and Pakistan. However, natural populations have been declined due to overexploitation and various ecological changes in its natural habitats leading to an alarming condition and deserving high conservation importance. This paper recommends actions for the conservation of the remaining isolated population of C. reba in Asian countries.

THREATENED FISHES OF THE WORLD: Eutropiichthys vacha (Hamilton, 1822) (Siluriformes: Schilbeidae)

River catfish Eutropiichthys vacha is one of the foods high in nutritional value in Asian countries. However, natural populations have seriously declined or are on the verge of extinction due to over-exploitation and various ecological changes in its natural habitats, leading to an alarm- ing situation which deserves high conservation attention. This paper suggests conservation measures that should be taken into account to- wards the preservation of the remnant isolated population of E. vacha in Asian countries.

THREATENED FISHES OF THE WORLD: Labeo bata (Hamilton, 1822) (Cypriniformes: Cyprinidae)

Minor carp Labeo bata is an endangered fish species in Bangladesh. This fish is one of the commercially and nutritionally valuable food fish in Asian countries including Bangladesh, India and Pakistan. L. bata is an important target species for small scale fishermen in Bangladesh who use a variety of traditional fishing gears. However, natural populations are seriously declining due to loss of habitat, siltation in the river basin, indiscriminate killing of fry and fingerlings, water pollution by industrial and domestic waste, agrochemicals and overexploitation. This paper recommends the sustainable conservation measures of this endangered fish species in Bangladesh and neighboring countries. CODEN RIBAEG ISSN 1330-061X (print), 1848-0586 (online)

THREATENED FISHES OF THE WORLD: Botia dario (Hamilton, 1822) (Cypriniformes: Cobitidae)

Bengal loach Botia dario is a valuable food fish in South Asian countries including Bangladesh, Bhutan, India and Nepal. However, the wild popula- tion is declining due to heavy harvest, habitat loss and its ecological chang- es. This paper suggests actions for the conservation of the lasting isolated populations of B. dario in Asian countries.

THREATENED FISHES OF THE WORLD: Ompok pabda (Hamilton, 1822) (Siluriformes: Siluridae)

The endangered catfish, Ompok pabda, is one of the foods high in nutritional value in Asian countries but its natural populations have declined due to over-exploitation and various ecological changes in its natural habitats leading to an alarming condition and deserving high conservation importance. This paper recommends the actions for the sustainable conservation of the remaining isolated population of O. pabda in Asian countries.
