Soft cover. Condizione: As New. From the introduction: "The Andaman and Nicobar Islands with extensive fringing reefs offer an ideal habitat for a large number of fish species comprising commercial, ornamental, poisonous and venomous nature. Several recent taxonomic studies revealed the existence of more than 1200 species of mar…ine fishes around A & N Islands (Talwar, 1990; Kamla Devi, 1991; Dorairaj et.al., 1994; Rao et. al., 2000). The occurrence of large number of fish species, high dependency of local population on the fish resources and paucity of information on the poisonous and venomous fishes encouraged the authors to study and update the knowledge of these fishes of A & N islands. The rich collections made by the authors from different localities of Andaman Islands and reference collections of Zoological Survey of India, Port Blair comprising 406 examples revealed the occurrence of 147 species belonging to 33 families, known to be harmful due to poisonous and venomous nature when eaten or pose danger while handling them carelessly or catching them by ignorance. The present report includes their taxonomic account along with information on habitat, distribution and the manner in which these fishes are believed to become poisonous or venomous. A brief account on the structure of venom apparatus, toxicity, symptoms and prevention of some poisonous and venomous fishes is given at the end. All the material studied was deposited in the reference collections of Zoological Survey of India, Port Blair.".

From the Introduction: "The present work is based on the material collected from the different habitats of these islands by the authors and various survey parties of Z.S.I. The material studied and… reported upon in the present account includes 2532 specimens belonging to 539 species from all the available habitats of the freshwater and marine environments in the A & N Islands. Of these 53 species indicated by asterisk (*) are recorded here for the first time from these islands. The following account includes key to families and taxonomic descriptions, habitats, distribution, etc. of the species encountered and key to distinguish them. The diagnostic features given are based on the specimens collected from the islands and studied by the authors, which have been listed under material examined in the text. Unless otherwise stated, the length of specimens given is total length. Only original bibliographic citation followed by important latest references pertaining to each species is given though several standard publications have been consulted for proper indentification and information on the distribution. The classification of fishes followed here is that of Nelson (1984), Smith and Heemstra (1986) and other revisionary works. 434 pp.

Aggiungi al carrellopbk. From the introduction Mangrove ecosystems are the most important and characteristic littoral plant formations of tropical and subtropical sheltered coastlines. Mangroves have suffered from a very poor reputation in the last several decades and further have often been considered unsafe worthless and harmful flies and mosquit…o infested areas being avoided by the people. Until very recently mangrove swamps were often considered unattractive and frequently cut down for fire wood. In times they have been re evaluated due to their principal ecological functions such as breeding spawning hatching and nursery grounds for a variety of marine fauna. They also play a major role in shoreline stability and prevent excessive erosion. They are systems of both high organic production and nutrient traps. Mangroves reduce the flow of nutrient loads into the sea and support the growth of seagrasses and corals around coastal regions. The mangrove ecosystem is highly productive and helps in exchange of matter and energy with adjacent terrestrial and marine ecosystems. The different macro habitats of the mangroves support rich and taxonomically diverse microbial floral and faunal components making this ecosystem a reservoir for abundant and unique biodiversity. Next to their ecological value mangroves provide abundant commercial products generating much needed economic opportunities in the coastal regions. The most important component of the economic potential of mangroves is the use of their biodiversity such as fishes crustaceans and molluscs. The fish is considered as one of the most important components of the mangrove fauna. The mangroves usually grow in sheltered low lying coastal areas mudflats tidal creeks backwaters marshes lagoons and estuaries of tropical and subtropical regions of the world. In India mangroves are distributed along the east and west coasts and Andaman and Nicobar Islands covering an estimated are of 6740 sp. km. (Das 2002) which constitutes about 7 percentage of the world mangroves. The three different types of mangrove forests found in India are deltaic backwater or estuarine and insular types. The mangrove vegetation usually grows on soft or compact mud sandy mud and rocks or adjacent to reefs. 228 pp. 160 figs (illustratore).
