Foreword The Mekong was always an international river, in the sense that foreigners were always interested in it. Since ancient times, people and goods have moved along this wide brown highway that preceded roads, railways and modern freight containers. As described in many historical accounts, it also provided access to the interior of the Mekong region to generations of conquerors, explorers and traders. The years of turmoil in the Mekong region account for much of the neglect of this major inland waterway in the latter part of the 20th century.

  • Species Composition and Invasion Risks of Alien Ornamental Freshwater
    www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people.

Aquatic nuisance species (ANS) are invasive animals, plants, and disease-causing pathogens that are “out of place” in Colorado’s rivers, lakes, streams, and wetlands . They are introduced accidentally or intentionally outside of their native range . Because they are not native to Colorado habitats, they have no natural competitors and predators . Without these checks and balances, the invaders are able to reproduce rapidly and out-compete native species . ANS have harmful effects on natural resources and our use of them . Aquatic Nuisance Species are Everyone’s Problem ANS damage Colorado’s lands and waters, hurt the economy, ruin recreation opportunities, and threaten public health . Many ANS consume enormous amounts of water and reduce the water supply for livestock, wildlife, and humans . They impede water distribution systems for municipal, industrial, and agricultural supplies . They can damage boats and fishing equipment and impair all forms of water based recreation . These species change the physical characteristics of bodies of water and alter food chains . As habitat is destroyed by invasive species, the wildlife that depends on it disappears as well .

  • An Overview of Water Quality Issues in Cambodia
    2 An Overview of Water Quality Issues in Cambodia K.N. Irvine, T. Murphy, M. Sampson, V. Dany, S.J. Vermette, and T. Tang Cambodia is amongst the poorest countries in the world, ranking 130 of 175 countries in the 2002 Human Development Index, as reported by the United Nations (www.un.org.kh/rcsystem/). The GDP per capita in 2002 was US$275 (www.state.gov/r/pa/ei/bgn/2732pr.htm). Life expectancy for men is around 54 and for women is 59, which reflects various factors, including high infant mortality rate and low living standards. Mortality due to waterborne diseases in Cambodia is high and is a situation that could be improved through better sanitary conditions and education. Cambodia also faces challenges related to population demographics (43% of the population is aged 15 or less) and the decimation of the skilled/educated sector of society during the Khmer Rouge period of 1975-79 (Gottesman, 2003). Estimates of the genocide vary, but Kiernan (1999) suggested about 1.67 million people, or 21% of the population perished during this period. Not only did the Khmer Rouge period exact a heavy toll on the Cambodian population, there also were major impacts on institutions and infrastructure within the country. Universities were closed, as were many primary and secondary schools. Although the Communist Party of Kampuchea (Khmer Rouge) had a Ministry of Education, there was little in Irvine, K., T.P. Murphy, M. Sampson, V. Dany, S. Vermette and T. Tang. 2006. "An Overview of Water Quality Issues in Cambodia." Journal of Water Management Modeling R225-02.

  • Giant Gourami
    Giant gourami The giant gourami (Osphronemus goramy) is a species of large gourami native to freshwater habitats in Southeast Asia, with its Giant gourami occurrence in other locations due to introductions. This species is commercially important as a food fish and is also farmed.[2] It can also be found in the aquarium trade.[3] The species has been used for weed control, also on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore.[4][5] It is capable of breathing moist air, so can survive out of water for long periods. It is much larger than most gouramis (only the other Osphronemus species reach a similar size), growing to a maximum standard length of 70 cm (28 in), though most are only around Adult [3] 45 cm (18 in). In colour, it is a pale to golden yellow, with silvery, Conservation status pale blue stripes running vertically along its body. Females can be identified by their thicker lips. Giant gouramis build nests using weeds and twigs.
