Book Description
INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.

Book Description
India has abundant water resources including rivers, canals, ponds, lakes, reservoirs, upland lakes, and floodplain wetlands covering over 5. [Author]8 percent of the country. [Author] These environments harbour a rich fish fauna of 1 035 species that constitutes the basis for the inland fisheries sector, which annually produces 2 144 452 tonnes of fish – if enhanced and culture-based fisheries are included – corresponding to 21 percent of total fish production. [Author] Rivers like the Ganga, Brahmaputra, and Barak, alongside floodplain wetlands, play crucial roles, especially in the east and northeast. [Author] Lakes are abundant in upland areas. [Author] Reservoirs cover over 1 percent of India's land and hold untapped potential for fisheries development. [Author] Traditionally, fishing in inland water bodies has been a small-scale or subsistence activity. [Author] Fishing practices, crafts and gear used in inland fisheries are still traditional. [Author] Cooperative societies are present in reservoirs and wetlands giving fishers better bargaining power with traders and better prices for the fish. [Author] Inland fisheries are imperative for poverty alleviation, food security, gender empowerment, cultural services, ecosystem function, and biodiversity, and are important for achieving the Sustainable Development Goals. [Author] Important threats to inland fisheries include water scarcity, habitat loss, pollution, climate change and invasive species. [Author] However, several major river conservation programmes have been initiated. [Author] The collection of inland fishery catch statistics remains weak and production appears to be significantly under-reported in many states. [Author] A simplified method for defining water bodies and estimating catch is proposed and all States have been advised to follow the same definition for water bodies. [Author]

Book Description
There are over 1300 species of cyprinids in Asia, and these are utilized by people for food (capture fisheries and aquaculture) and as ornamental species. This publication focuses on cyprinid species that are bred in hatcheries and used in aquaculture and restocking activities. Introduced and threatened species of cyprinids in Asia are also discussed. We are well aware that we have not covered many other cyprinid species that are utilized by people in Asia in various ways: wild species in capture fisheries, self-recruiting species in aquaculture ponds and other water bodies, and aquarist species.

Book Description
The existing literature on limnology and fisheries of Indian reservoirs has been reviewed by covering more than 100 reservoirs located in various parts of the country. An assessment of environment-mediated production functions of reservoirs has been attempted. Since the ecosystem processes in reservoirs belonging to different geo-climatic regions exhibit wide variations depending on meteorological, morphometric and hydro-edaphic features of the impoundments, an effort has been made to gauge the influence of these abiotic variables on the production dynamics. Authentic information on water areas under different categories of reservoirs has been collected and interpreted in respect of all the Indian States. An attempt has also been made to resolve the anomalies pertaining to classification and nomenclature to the extent possible. Various fisheries management norms followed in the reservoirs of the country including the selection of species for stocking, stocking rate and introduction of exotic species have been reviewed. Indian reservoirs have been stocked with the Indo-Gangetic carps for many decades and the impact of this stocking has been assessed in terms of fish production and the indigenous faunistic diversity.

This work describes when, where, why, how, and by whom the various freshwater fish species now established in the wild outside their natural range were first introduced. It also explores what, if any, ecological impacts they have had on their new ecosystems.
