      Biodiversity in the Mekong Fish species diversity in the basin is current estimated at species, and could be as high as species. In addition, the Mekong fish fauna, as in other large rivers, is probably characterised by a high degree of within species diversity. This, in part, is brought about by. Ho live mainly in the lower Mekong basin in Vietnam and Cambodia, but population has declined sharply due to overfishing. Ngai said since April he had not heard ho anyone catching a ho weighing more than kg in the delta. The fish grow to kg when fully mature. The centre now has 84 breeding pairs of ho, with the largest weighing. River Commission, ). The lower Mekong River ecosystems with its extensive associated floodplains and wetlands supports important inland fisheries (Baran et al., ). The fisheries are a major factor in the well-being and livelihoods of the people who live in the lower Mekong Basin (Mekong River Commission, ). Some 40Cited by: 9.   Results. The MRC has formally adopted six dam-development scenarios for and , known as Basin Development Plan 2 scenarios (BDP2) ().These scenarios include between 16 and 78 tributary dams and up to 11 main-stem dams (Fig. 1 and Table 1).Using our model, we estimate the impact of each scenario on the biomass of migratory species in the floodplains, as well as the Cited by:

The Mekong is one of the world's largest rivers with a basin that supports a population of about 70 million people, for most of whom the staple diet is rice, fish and other aquatic the basis of altitude, hydrology, and landforms, the basin is usually divided into the Upper Mekong (in China and Myanmar), comprising about 20% of the catchment, and the Lower Mekong Cited by: 70% of freshwater aquaculture production come from cage culture (total: 4, fish cages) operated in Mekong basin, including the Tonle Sap Great Lake (43%), Tonle Sap River (17%), upper stretch of the Mekong River (19%), lower stretch of the Mekong River (14%) and Bassac River (7%) (So &.

Myanmar - aquaculture and inland fisheries Inland fisheries and aquaculture resources. Myanmar has impressive freshwater capture fisheries. The inland waters are made up mainly of the interlocking/ mingling of riverine and estuarine systems of the Ayeyarwaddy (Irrawaddy, 2 km long), Chindwin ( km; a tributary of the main Ayeyarwaddy) and Sittaung ( km) rivers, plus the large Thalwin.

Since the s, aquaculture has attracted the lion's share of support and resources from governments and non-governmental organizations in the Lower Mekong Basin in the name of rural development Author: Simon R.

Freshwater ecosystems are, however, under increasing. Cage and pen culture, reportedly originating in Cambodia, is the major farming system of freshwater aquaculture production and its history dates back to the 10 th century.

As a result of the particularities of the hydrological cycle of the Mekong River and its natural buffer reservoir, the Great Lake, the freshwater fish catch has always been highly seasonal, especially for the large.

freshwater small-sized fish species were detected in the Mekong River Basin of Cambodia and Vietnam, and these freshwater small-sized fish species, including juveniles of commercially important fish species, contribute more than 70% to total freshwater capture fisheries production.

Thus aquaculture was closely tied to the same fish stocks exploited by the fisherfolk of the lower Mekong Basin. Fisheries production in the lower Mekong Basin. Reliable statistics of fisheries production in the basin are sorely lacking.

Many estimates are no more than educated guesses. In book: White Gold: The Commercialisation of Rice Farming in the Lower Mekong Basin (pp) orchards, and freshwater and brackish-water aquaculture.

Fish migration triggers in the Lower Mekong Basin and other tropical freshwater systems early rainfalls. In several river systems, the migrations cued by the first rains are also associated with the lunar cycle.

Changes in turbidity, or in water colour, are recorded as migration triggers for nine species in the Mekong River system. Freshwater aquaculture refers to raising and breeding aquatic animals (fish, shrimp, crab, shellfish, etc.) and plants for economic purposes by the use of ponds, reservoirs, lakes, rivers, and other inland waterways (including brackish water), which play an important role in the aquaculture industry.

The main breeding targets are fish; breeding shrimp consisting of Macrobrachium and Hainan prawn; and crabs. A large proportion of the aquaculture production in the Lower Mekong, particularly for snakehead and catfish, depends on low-value “trash fish” for feeding.

Depending upon the season and locality, a significant proportion of that trash fish can come from the freshwater fishery. In this and the next three chapters, the focus shifts to the Mekong Delta in Vietnam, which accounts for 15% of the Lower Mekong Basin by area and 27% of the total paddy area but in produced 48% of the Basin’s total rice output and about 60% of its rice exports (Fig.

Table 1 provides an overview of the fish production systems, water management practices and ecosystem services considered in each of. In the Lower Mekong Basin, total ground water reserves are thought to be about to km 3.

While there are eight main transboundary aquifer systems in the Lower Mekong Basin, they are not extensive as many are located along high elevation areas that are characterized by low-yield bedrock, which is not conducive to ground water collection.
