Parasitic Worms Of Fish

Fish are a unique group which harbour some 30,000 species of helminths that do not occur in other vertebrates. This book deals specifically with parasitic worms of fish. It covers every aspect of their biology including identification, life-cycles, hostparasite relationships and ecology. It discusses approaches to studying parasitic worm infections, preference of species for particular host species, preference for dwelling in certain organs and tissues, biogeography, seasonality of infections and how parasites have evolved in parallel with their hosts. The book concludes with discussions of fish worms causing diseases in nature and in fish-farms.

This section also addresses the value of parasitic worms in extending knowledge of the environments in which fish and their parasites dwell, from the use of worms as indicators of pollution or for determining the location, migrations, and feeding behavior of fish stocks. With the growth in fish farming such parasites have considerable economic as well as scientific significance.; This volume provides an account of these helminths and reviews how studies on fish worms have increased current knowledge of worm biology in general.; The bibliography contains over 3500 references and an appendix summarizes important information on biochemistry and physiology of fish worms.

Information on the parasites of Canadian fishes published between the years 1978 and 1993, inclusive, is assembled as Parasite-Host and Host-Parasite lists. The 925 named species of parasites are reported on 292 species of Canadian fishes. The Parasite-Host list is organized on a taxonomic basis and identifies for each species its habitat (freshwater, marine, or brackish), site of occurence in its host(s), species host(s), known geographic distribution within Canadian waters, and the published source for each host and localty record. The Host-Parasite list is organized according to the taxonomy of the hosts and is accompanied by data on the known Canadian distribution of the parasites. For both the Parasite-Host and Host-Parasite lists, a "Remarks" section containing explanatory comments concerning systematics, nomenclature, and notes on other specific items is included as warranted. In addition to listing the cited references, as supplentary list of references is included to cover other Canadian literature on fish parasites.

Focusing on pathobiology and protective strategies against protozoan and metazoan parasites of fish, this book reviews the latest research on important parasites: those that cause financial hardships to the aquaculture industry, have been introduced to new geographical regions through transportation of infected fish, are pathogenic to groups of finfish and detrimental to production, are highly adaptable and not host-specific with worldwide distributions, and that may serve as disease models for studies on other pathogens. It also highlights gaps in the knowledge to help direct future research.

The entitled book "Freshwater Fish Parasites" spread over 10 chapters, with complete pictorial guide of different fresh water fish parasites all over the country. The detail etiology, clinical signs, prophylaxis and treatment of parasitic diseases have been discussed in a simplified manner for easy understanding of students, researchers, teachers, scientists and farmers in the field .The book covers most interesting chapters and will guide to identify and manage parasitic diseases including some aspects of latest developments in fish parasitological research. A comprehensive approach has been made to cover all the progressive areas of parasitic disease management starting from identification of the parasites, basic status of diseases towards various approaches to diagnose, prevent and control disease conditions. The parasitic problems of different fishes, like indigenous fishes, exotic fishes of commercial importance, sport fishes and ornamental fishes have been addressed to give a complete parasitic disease profile on total fishery. The behavior of the hosts, interrelationship of soil and water with parasitized hosts, and mechanism of parasitic attachment are important aspects of the concerned book.
