It is a well known assertion that for any phylogenetic interpretation, especially of the vertebrate phyla, the organization of the basic structural pattern and anatomical features are the essential base. From Agassiz’s time (1857) the internal skeletal structure and the associated modifications as reflected in the external morphology have been utilized for classifying the families and the genera of fishes. One of the reasons for depending upon the basic ...
Cyprinoidei are a suborder of the fresh water fishes of the order Cypriniformes, under superorder Ostariophysi of which 250 genera and 2500 species are known to exist all over its range. Of the families known of this suborder, Cyprinidae is by far the most abundant and dominant in respect of species proliferation and also in successfully occupying niches over-running other groups. The suborder is found in Eurasia (as far east as the Wallace’s Line) North ...
This book is primarily meant for beginners in fish taxonomy, students, teachers and amateur naturalists who are interested to know the different aspects of fish, their diversity, diagnostic characters, methods of collection, preservation, future care, gears employed and means to identify them and give a correct scientific name. The various technical terms used in selection of types, how they are selected, the rules governing them, the regulations of the ...
Fishes of the genus Labeo Cuvier are widely distributed throughout India, Afghanistan, Pakistan, Bangladesh, Myanmar, Thailand up to South China. They are well represented with about 49 species in tropical Africa and Syria. It has a limited distribution in Sri Lanka; 28 species are known from the Indian region. It is well known that the Indian sub-region of the Oriental Region has perhaps the largest number of fish genera representing nearly 63% of the 89 ...
Nearly ten years back the first edition of this book was ably published by the present publishers. In the intervening period systematic ichthyology has advanced very rapidly new discoveries of taxa, new areas previously unexplored and new concepts of taxonomy and new classification of the existing families, genera and species were brought to light. Many foreign ichthyologists undertook surveys in difficult areas and contributed much knowledge. The all catfish ...
India has vast aquatic resources with varied eco-climatic zones, which harbour a rich fish germ plasm resource. Out of 20,000 species of fishes known so far the world over 11% are in our country, About 2200 freshwater fish species have been reported by the National Bureau of Fish Genetic resources out of which 73 species (3.32%) are found in coldwater, 544 (24.72%) in warm freshwater, 143 (6.51%) in brackish water and 1440 (65.45%) in our vast marine waters (Das, ...
Nearly thirty years ago, 29 years to be exact, a concise systematic account of the Catfishes (order Siluriformes) of the Indian region consisting of India, Bangladesh, Myanmar, Nepal, Pakistan and Sri Lanka was published by the late Dr. K.S. Misra of the Zoological Survey of India in the Fauna of India series. In the intervening years the concept of catfish taxonomy has undergone vast changes. Many new taxa have been described. A new interest in unraveling the ...
