Book excerpt: With the decline in world fish stocks, our knowledge of fish reproduction has become fundamental. Reproduction is an essential commitment to future generation. It is also a continuous development process throughout ontogeny, requiring energetic, ecological, physiological, anatomical, biochemical and endrocrinological adaptations. The first chapters
Download or read book Percid Fishes written by John F. Craig and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The percid fishes (or perch family) comprise many species including the perch, pikeperch, yellow perch, walleye and the darters. These species are of great ecological and economic importance, being important components of the freshwater ecosystem and recreational and commercial fisheries. Percid Fishes covers aspects such as systematics, morphology, biology, ecology, diseases and parasites and the economic importance of percid fisheries. Special emphasis is placed within the book on the complex relationship between this family of fishes and their environment and how they respond to perturbations, especially those induced by humans. The author, John Craig who has a great deal of experience working on these fishes in many of the countries in which they occur, has drawn together an extremely important book which provides a unique, comprehensive and indispensable review of this most significant group of fish.
Download or read book Yellow Perch Walleye and Sauger Aspects of Ecology Management and Culture written by John Clay Bruner and published by Springer Nature. This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.

This book was released on 2019-07-28 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the

This book was released on 2019-09-12 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.
Download or read book Freshwater Fishes in Britain written by Cynthia Davies and published by BRILL. This book was released on 2021-10-25 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most British natural historians, there is one vertebrate order that could well be said to be “out of sight, out of mind.” This is our freshwater fishes, familiar principally only to anglers, those concerned with managing rivers and other waterbodies, and a few research scientists. The results of this project, which ran from 1998-2002, are published here in the form of comprehensive 10km square dot-distribution maps for the 54 species inhabiting England, Scotland, Wales, the Channel Islands and the Isle of Man. These indicate the vulnerability of several of our native British species. Following a wide-ranging introductory chapter, and further chapters on distribution and the history of the project, Chapter 4 comprises the individual species accounts under the headings: Description; Biology and behaviour; Habitat; Distribution in Britain; World distribution; Status; Hybrids and related species; and a final section of the relationship of each species with Man. In addition to a map, each species is illustrated by fine lithographs taken from Francis Day's famous 19th century work, skilfully supplemented by Michael J. Roberts for those species unknown to Day. Chapter 5 covers conservation and management of freshwater fishes and is followed by four Appendices relating to (1) Publications; (2 & 3) Legislation; and (4) Selected websites relating to environmental protection, biodiversity information and fish conservation. The book concludes with a Glossary; a comprehensive Bibliography; and an Index. In his Foreword, Sir John Burnett, Chairman of the National Biodiversity Network Trust, commends this books as “a unique reliable source of clear and comprehensive information that is pleasing both to the mind and to the eyes” and expresses the hope that “it will lead to ... the more effective conservation of this ‘alien race’ in our midst.” A joint project of the Environment Agency, the Centre for Ecology and Hydrology and the Joint Nature Conservation Committee; written by a team of 38 authors and compiled and edited by Cynthia Davies (CEH), Jonathan Shelley (EA), Paul Harding (Biological Records Centre, CEH), Ian McLean (JNCC), Ross Gardiner (Fisheries Research Services) and Graeme Peirson (EA).
