Download or read book Research Trends on Fish Fisheries in Mountain Waters of Eastern Himalayan Region written by Debangshu Narayan Das, Santoshkumar Abujam, Achom Darshan Singh and published by Notion Press. This book was released on 2019-05-10 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a total of 25 unpublished research articles. In this edition, we have kept parity with each other’s outcomes, concisely in a unique style to depict the trends of research in the mountain fishery sector. We have also appended a list of contributors at the end of the book. The strategies observed in fisheries and aquaculture developments in the mountain waters clearly reveal that the on-going dimensions are nothing but broad ecosystem-based approached where both subsistence and commercial expansion of the systems could be possible. The research trend also directs that several fishery components, like ornamental fisheries, recreational fisheries, integrated fish farming, freshwater crab fishery, shellfish aquaculture, etc., exist. They may also be strengthened in mountain waters to improve the economic status of the mountain regions. Thus for exploiting huge mountain aqua-resources, Arunachal Pradesh targets the ecosystem-based approach of raising native mahseers, like Tor tor, Tor putitora, Neolissochilus hexagonolepis, and exotic species of trout in its mountain waters as a preliminary endevour.

Download or read book Freshwater Fishes of Manitoba written by Kenneth Stewart and published by Univ. of Manitoba Press. This book was released on 2004-05-03 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manitoba's ninety-three species of fish give the province the third most diverse fish population in Canada. The provinceís variety of geological features, with its major lakes, rivers, tributaries, and watersheds, is due in large part to its history as the basin for Glacial Lake Agassiz. This, combined with its access to the waters of Hudson Bay and large American river systems, has provided habitat for a wide diversity of freshwater fish. Species from lampreys to goldeye, catfish to perch, bigmouth bass to slimy sculpin swim in waters from arctic rivers in the north to Red River tributaries and down to the Mississippi in the south.Freshwater Fishes of Manitoba is a comprehensive, user-friendly guide. Each species is accurately depicted in detailed colour photographs and accompanying map, with descriptions of physical characteristics, spawning and feeding habits, distribution, habitat, ecological role, and economic importance. The guide also includes an extensive glossary, keys to identifying the families, species, and subspecies, and information on documentation and preservation of specimens. Freshwater Fishes of Manitoba is not only the definitive guide to these fishes of Manitoba, it is also accessible and reliable for a range of users from general fishers to professional fish biologists.

Download or read book The Ganga a Scientific Study written by C. R. Krishna Murti and published by Northern Book Centre. This book was released on 1991 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book Ganga: A Scientific Study is based on an Integrated Research Programme carried out by 14 Universities located in the Ganga Basin sponsored and funded by the Envioronment Research Committee and The Ganga Project Directorate, Ministry of Environment & Forests, Government of India, New Delhi. The Ganga, one of World's major rivers, has been venerated as the holiest and is bound with countless beliefs and faiths especially in India and adjacent countries. Its water has traditionally been regarded as an inexhaustible gift of nature. Recent experiences do not, however, warrant such a complacency. The water resources are strained to a non-sustainable level due to rapid population explosion, urbanisation, development of agriculture, industry, livestock and power production in the Ganga basin. The hydrobiological quality of water has deteriorated and yet no concise, valid supporting evidence was available in a comprehensive manner covering the entire river. This book is an attempt towards this direction. For the first time a picture of the Ganga is available with its physico-chemical and biological charateristics, the severe pollution stress and causes to which its water is subjected to, the contents and quality of water and possible remedial measures. An account of algae including pollution sensitive and tolerant species, besides bio-indicators is available. A possible modelling exercise has also been included. A microbiological assay and the bacteria present in the river water is also given. This book, in short, is a synthesis of what the Ganga is at present in respect of its hydrobiology, pollution load, and some aspects of hydrology.

Download or read book Ecology of Teleost Fishes written by Robert J. Wootton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious and delicious food of numerous kinds. Rational expoitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Download or read book Migration of Freshwater Fishes written by Martyn Lucas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.

Download or read book The Carp written by R. Billard and published by Springer Science & Business Media. This book was released on 1999-04-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a group, carp provide 4 million metric tonnes of fish annually - over a quarter of all fish culture worldwide. For the first time, a book is available in English that concentrates solely on the carp as an economic rather than an ornamental fish with a panel of international experts producing a comprehensive, practical volume about carp production and management. Starting with a brief look at the biology of cyprinids, the book then discusses the methods and management of carp farming, from water quality to the economics of fish production in ponds. Novel methods to improve stock, including genetic engineering, are covered and case studies give added value to the text. As carp farming turns from traditional to intensive methods, farmers, researchers and technicians in industry will welcome this benchmark volume, which also is a valuable reference book for graduate and postgraduate students and lecturers in aquaculture.

Download or read book Biology of Subterranean Fishes written by Eleonora Trajano and published by CRC Press. This book was released on 2010-05-20 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most habitats, adaptations are the single most obvious aspects of an organism’s phenotype. However, the most obvious feature of many subterranean animals are losses, not adaptations. Even Darwin saw subterranean animals as degenerates: examples of eyelessness and loss of structure in general. For him, the explanation was a straightforward Lamarckian one, and one that did not involve adaptation and the struggle of existence. This volume is a comprehensive account of all known species of subterranean fishes. It includes an extensive introduction, history of investigations, consideration of non-stygobitic fishes in caves, and detailed analysis of the conservation status of these very rare animals.
