Various human activities in fulfilling their lives have naturally damaged the barrier of the freshwater fish distribution, caused the geographical limitation, which is no longer a restraint in the spread of a species in the waters (Su et al., 2016). Meeting the need for food and protein sources is the main reason for introducing and moving a particular species to be developed in other areas that are considered to have a typical habitat through aquaculture activities (Syafei & Sudinno, 2018). In addition to these objectives, some fish introductions are carried out to fulfill hobbies, recreation as well as for other economic reasons which have generally taken place in many parts of the world (Kiruba-Sankar et al., 2018). With the diversity of species introduced in an area, ultimately makes it unclear as to which boundaries are native and non-native species. It

This Present study is aimed to determine the diversity and distribution of Alien Macrophytic plants found in the Arthuna pond of Garhi Tehsil in Banswara District of South Rajasthan. In the years 2019 and 2020, the specimens were collected from four sites located from the north to south and east to west of study area. A total of seven species belonging to six genera and six families are reported as Invasive Alien Macrophytes. These are Ipomea sps., Nymphoides, Nymphea, Nelumbo, Potamogeton, Azolla belonging Convovulaceae, Menyanthaceae, Nelumbonaceae, Salviniaceae, Nympheaceae, Potamogetonaceae respectively. Physicochemical parameters like water pH, Temperature, TDS, Dissolve oxygen, Turbidity were analysed in three seasons winter, summer and rain. The Invasive Alien Species possess serious threat to local diversity and human Health therefore systematic study about the invasive plant species is necessary

Koshi Tappu Wetlands play a significant role in the conservation of many rare and endangered species of flora and fauna. However, this wetland is threatened by several natural and anthropogenic stressors; among others, invasion by invasive species is the most serious problem. The objective of this study was to prepare an inventory list of wetlands, categorize the wetlands based on the coverage of alien species, identify the problematic aquatic invasive plant species, and assess their impact on water quality and aquatic biodiversity (fish and macroinvertebrates). This study was conducted in winter and spring seasons of 2018. Composite water samples were collected from the wetlands with different covers of invasive species. Macroinvertebrate samples were collected using hand net of 500µm mesh following the habitat specific sampling approach, and fishes were sampled using Cast Net. The analysis of water quality parameters, macroinvertebrates and fishes were performed for different leve...
Distribution of alien invasive species in aquatic ecosystems of the southern Western Ghats, India
Aquatic Ecosystem Health & Management
We present results of the first major attempt to record the distribution of aquatic alien species in the Western Ghats Biodiversity Hotspot using Geographical Information System. A total of 32 alien species, including four macrophytes (Salvinia molesta, Pistia stratiotes, Eichhornia crassipes and Cabomba furcata) and 28 fish were recorded from the southern part of the Western Ghats. Seven of these have established natural populations and are invasive, which includes Oreochromis mossambicus, O. niloticus (Cichlidae), Poecilia reticulata, Gambusia affinis (Poeciliidae), Pterygoplichthys pardalis (Loricariidae), Cyprinus carpio (Cyprinidae) and Clarias gariepinus (Clariidae). Oreochromis mossambicus is the most extensively distributed invasive fish in the region. Major reservoirs serve as a spawning hub for species such as C. gariepinus and C. carpio. Significant pathways for the establishment of most alien species in Western Ghats were aquarium trade and aquaculture. Given the increas...
Survey of alien invasive aquatic and semi aquatic plant speciesof Santhal Pargana, Jharkhand
Alien invasive plants are an exotic, introduced, foreign, non-indigenous or non-native plant, which has been introduced by humans intentionally or otherwise through human agency or accidentally from one region to another. Aquatic and semi aquatic angiosperms are very important forms of plant life and they find a more or less precious footing in pond ecosystem. The studies of invasive aquatic and semi aquatic plant species of Santhal Pargana from the year 2011 to 2016 has revealed that these plants are responsible for the loss of native aquatic biodiversity. Some of these plants have great source of food. Aesthetic importance of these plants cannot be ignored. The current paper is an endeavor to compile the list of invasive aquatic and semi aquatic plant species of Santhal Pargana. A survey conducted in the Dumka district reveals the occurrence of 30 species of invasive aquatic and semi aquatic medicinal plant representing 26 genera and 17 families.
Alien plant invasion in water systems in Shanghai, China 【Review】
Journal of International Development and Cooperation, 2004
Biological invasion is one of the most three critical environmental problems in the world. Biotas in water system are always changing rapidly because of being weak at invasion resistant. In this paper, two typical invasive plant species in water systems in Shanghai was discussed. (1) Eichhornia crassipes, in freshwater system, whose invasion process, invasion mechanism, harm, and control strategies were elucidated; (2) Spartina alterniflora, in estuarine water system, whose transplanting in Chongming East Beach of Shanghai causes large controversy, was recognized as a critical invasive species. The current idea for these two plant species and some suggestions on study and control of biological invasion were discussed.
