Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range ofbiological adaptations to diverse habitats has evolved. As weIl 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 of the survival of the human species in the form ofnutritious and delicious food ofnumerous kinds. Rational exploitation 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.

Available in PDF, EPUB and Kindle. Book excerpt: As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.

This book was released on 1999 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainboth (1996b) has varified all Puntius species of Smith (1945) into 4 genera, Puntius, Systomus, Barbodes and Hypsibarbus by taking their distinctive external morphological differences into account. Since cytotaxonomy by the studying of karyotypes and distributions of nucleolus organizer regions (NORs) might provide possible useful data to support such taxonomic problem or vice versa. This study was therefore designed to do comparative study by examining some external morphological features but emphasizing on the comparison of karyotypes and distributions of NORs of a representative cyprinid species of those above 4 genera, they are Puntius brevis, Systomus orphoides, Barbodes gonionotus and Hypsibarbus wetmorei, respectively. The fish materials in this study were obtained from middle plain of the Chao Phraya river system. Each species was taken at the place as many as enough for selection. For morphometric and meristic studies ten specimens of each species were encountered. Whereas another ten specimens of both Barbodes gonionotus and hypsibarbus wetmorei, eight specimens of Puntius brevis and 6 specimens of Systomus orphoides were used for the studies of karyotypes and distribution of NORs. From the obtainable data on the external morphology of the sole representative species of the four genera, they exhibit a number of distinctive feature to render the agreeable separation of the species at the generic level. To support the above taxonomic throught, this further study on karyotypes and distributions of NORs have shown that although all the four species of different genera has similarly 50 diploid chromosome number(2n), however, the combinations of chromosome types, arm number (NF), number and location of NORs are likely different. For Puntius brevis, the karyotypes comprise of 2m, 2sm, 2st and 44a; 54 for NF and NORs have one pair which locate on the satellited regions of a subtelocentric pair on short arms. Systomus orphoides, the karyotypes comprise of 12m, 20sm, 4st and 14a; 82 for NF and NORs have one pair which locate on the satellited regions of a submetacentric pair on short arms. Barbodes gonionotus, the karyotypes comprise of 6m, 16sm, 6st and 22a; 72 for NF and NORs have two pairs which locate on the satellited regions of a submetacentric pair on short arms and on the satellited regions of an acrocentric pair on short arms. Hypsibarbus wetmorei, the karyotypes comprise of 12m, 4st and 55a; 74 for NF and NORs have one pair which locate on the satellited regions of an acrocentric pair on long arms.
