Red dwarf rasbora (Microrasbora rubescens) is a species of cyprinid found endemic to Lake Inle in Shan State in Myanmar. [1] It belongs to the genus Microrasbora , which contains two small species of danionins. [2]
The dwarf red rasbora reaches up to 3.0 cm (1.2 in) in length. Its meristics are that there are 2 spines and 6-7 soft rays in the dorsal fin and 3 spines and 10-12 soft rays in the anal fin. [3] The females are less instensly coloured than the males and are larger and have a much deeper body. [4]
The dwarf red rasbora is endemic to Lake Inle which is situated in a valley where the rocks form a karst and which lies 900m above sea level in the Shan Plateau region of Shan State. [4] Within the lake this species can be found in the midwater and in the marginal waters of Lake Inle where it is associated with submerged vegetation and forms large schools. [1]
The red dwarf rasbora is exploited for the aquarium trade and it is thought this may have some impact on the population. It is also threatened by the introduction of exotic fish species to the lake, particularly Parambassis and Tilapia species, which act as both predators on and competitors with the red dwarf rasbora. In addition the lake has been polluted from a number of sources, especially from the growing human population in settlements around the lake, while sedimentation and agricultural runoff enters the lake from its drainage basin. The invasive water hyacinth has covered large areas of the lake and this has reduced the area of open water in the lake, this effect being exacerbated by water abstraction and sedimentation. [1]
The common dace is a species of freshwater and brackish water ray-finned fish from the family Cyprinidae which is native to Europe but which has been introduced to other parts of the world. It is a quarry species for coarse anglers.
Inle Lake, a freshwater lake located in the Nyaungshwe Township of Shan State, part of Shan Hills in Myanmar (Burma). It is the second largest lake in Myanmar with an estimated surface area of 44.9 square miles (116 km2), and one of the highest at an elevation of 2,900 feet (880 m). During the dry season, the average water depth is 7 feet (2.1 m), with the deepest point being 12 feet (3.7 m). During the rainy season, this can increase by 5 feet (1.5 m).
The northern redbelly dace is a fresh water cyprinid fish, generally found in lakes and small streams in the northeastern United States and eastern Canada. Ranging from 1-3 inches, it is one of forty-four species from the minnow and carp family of Cyprinidae in these areas.
Microrasbora is a genus of small fishes. The generic name means "small Rasbora", however these are more closely related to the danios than rasboras. They inhabit freshwater in Myanmar and Yunnan, China.
Channa harcourtbutleri, the Burmese snakehead, is a species of snakehead endemic to Inle Lake and surroundings in Myanmar. Locally called nga ohn-ma, among aquarists it is considered one of the dwarf snakeheads, but no significant import for aquarists is known. It is one of the smaller species of snakehead and has a standard length of up to 19.4 cm (7.6 in). The specific name honors Sir Harcourt Butler, a British governor in the region.
Microdevario kubotai is a species of cyprinid found in southeast Asian rivers and streams. It belongs to the genus Microdevario, which contains small danionins. The type locality is in Ranong Province, Peninsular Thailand. It is also known from the adjacent Phang Nga Province and the Ataran basin in Myanmar. It likely occurs elsewhere in the region and an introduced population exists in the Songgaria River. It reaches up to 1.9 cm (0.75 in) in length.
Danio margaritatus, the celestial pearl danio, often referred to in the aquarium trade as galaxy rasbora or Microrasbora sp. 'Galaxy', is a small cyprinid from Myanmar. It has so far been found only in a very small area near Hopong east of Inle Lake, at an elevation of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn Rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit.
Rasbora tawarensis, locally known as depik, is a critically endangered species of cyprinid fish. It is endemic to Lake Laut Tawar in Indonesia, where its population is rapidly decreasing due to ecological disturbances, global warming, introduced species, unlawful fishing practices, and pollution.
Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.
The konye (Konia eisentrauti) is a critically endangered species of fish in the family Cichlidae. It is endemic to Lake Barombi Mbo, a crater lake in western Cameroon. It is threatened because of pollution and sedimentation due to human activities, and potentially also by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos). This species can reach a length of 9.3 centimetres (3.7 in) TL.
Dendrochirus barberi, the Hawaiian lionfish or green lionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes and lionfishes. It occurs in the Eastern Central Pacific. It occasionally makes its way into the aquarium trade.
The sawbwa barb, also known as the Burmese rammy nose, Asian rummynose or rummynose rasbora, is an endangered species of cyprinid fish in the monotypic genus Sawbwa. The species is endemic to Inle Lake in Myanmar (Burma). It grows to a maximum total length of 3.5 cm (1.4 in). Mature males are iridescent silvery-blue with red snout and red lobes to the tail fin; females are duller without red and with a dark pigmentation spot by the anus. The sawbwa barb completely lacks scales.
The Upper Zambezi labeo is a species of cyprinid fish of the genus Labeo native to southern Africa.
The yellow rasbora is a species of ray-finned fish in the genus Rasbora from Southeast Asia. It is a primarily freshwater fish originally from Java island in Indonesia. It is known as the Wader pari fish in the Indonesian language. In addition, it was a protein source for the local community during the old days.
The redeye barb or Beira barb, is a widespread African species of freshwater cyprinid fish which is found from Uganda south to the Limpopo River and Incomati River systems in South Africa.
Cyprinus intha is a species of ray-finned fish in the genus Cyprinus. The species is endemic to Inle Lake, a large, isolated freshwater lake on the Shan Plateau in eastern Myanmar. It is considered to be endangered, among other reasons, because of widespread hybridization with introduced Common Carp, Cyprinus carpio.
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio, Devario, and Rasbora. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Danio species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Devario species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.
There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. Different types of fish flourish in different water sources. The waters of Uganda contain an impressive array of fish species—over 90 in all. This count does not include the Haplochromis complex, which itself is made up of more than 200 species.
Aphyocypris lini, the garnet minnow or Venus minnow, is a species of cyprinid endemic to China. It was first collected from Hong Kong by A.W. Herre in 1936. The introduction of mosquitofish and habitat destruction caused the extirpation of this species from Hong Kong and the species was considered to be extinct in the wild. However, a similar species Aphyocypris pulchrilineata was discovered in Guangxi in southern China, but this species lacks the dark spot on the base of the caudal fin.
