Apple snails have become a major pest of wetland rice in much of Southeast Asia. Two species are involved, Pomacea canaliculata and P. maculata. One or both of these species have become widely established not only in many parts of Southeast Asia but also in other parts of the world. This book provides an update on research into the biology, management and use of apple snails and highlights the need to prevent further spread of these species.

In the north-east hill region of India, integrated fish farming is one of the best alternatives for improving livelihoods as most of the houses in rural areas have access to ponds and livestock. Among livestock, pigs are a popular choice, particularly for the tribal population of the region, who account for a major portion of the population. Pigs can fit into diverse systems of management, and can be reared on a wide variety of waste materials.

Among the freshwater catfishes, magur (Clarias batrachus) is in great demand in eastern and north-eastern India; it is revered as highly nutritious and therapeutic in nature. During May-June 2016, Sri Sayer Mohammad Sarkar, an experienced magur breeder and seed producer, has achieved success in producing induced-bred hybrid seed of Heteropneustes fossilis and Clarias batrachus. His breeding protocol and experiences in nursery and growout of hybrid catfish are shared in this article.

Murrels (snakeheads) are the third most important group of freshwater fishes in India after carps and catfishes. Murrels are the most common and dominant group of air breathing freshwater fishes and are highly regarded as food fish. Murrels have a pair of cavities in the pharynx that have folded linings, richly supplied with blood vessels for taking in air. These organs enable these fishes to survive out of water for a few hours or migrate from one pool to another.
