Induced Fish Breeding: A Practical Guide for Hatcheries takes a successive approach to explaining the use of breeding technology with proven scientific methods. It provides real-life examples for the purpose of maximizing fish and seed production to support overall sustainability in aquaculture. It is a concise reference to understanding the latest developments in the field, useful for anyone who is involved in fisheries or hatchery management as well as researchers and students who need to understand the technology. A practice originally developed to produce quality seed in captivity, induced breeding has made great strides in fish populations for India. The book offers a practical and succinct overview—from existing methods and operations to recent trends and their impacts on aquaculture for the future. Provides detailed information about empirical breeding practices like mixed spawning and indiscriminate hybridization Presents the environmental and hormonal influence on maturation and spawning of fish with real-life fish breeding examples from around the world Includes step-by-step scientific measures to help solve problems arising from common fish-farming mistakes Provides real-life examples for the purpose of maximizing fish and seed production to support overall sustainability in aquaculture

A. CORBIN Investigations on LHRH and its analogs have just completed their first decade. We have witnessed a veritable explosion of chemical, physiologic and pharmacologic data on this hypothalamic peptide and the approximately 1500 agonist and antagonist analogs that have been synthesized. In order to track this expanding field, I was asked to organize an international symposium on basic and clinical aspects of LHRH analogs as part of the Reproductive Health Care: CDS Symposium held in Maui, Hawaii, in October 1982. This meeting brought together a number of the leading investigators in the field. Much new state-of-the-art information was presented which I and my colleagues felt deserved a wider audience. Drs Vickery, Nestor, and Hafez consented to undertake this task. Upon review of the literature, it was apparent that there was no recent text which fully covered the breadth of developments in the field. Accordingly, the editors decided to use the symposium as a nucleus on which to build a singular, comprehensive state-of-the-art analysis of this rapidly growing discipline, and the application of such knowledge to reproductive medicine. As exemplified by the various areas of expertise provided by the individual contributors, it becomes obvious that the scope of the subject matter, while relating solely to a well-defined chemical class (LHRH analogs) and a circumscribed physiologic and pharmacologic entity (reproduction), has expanded enormously.

The book entitled “Broodstock Management and Fish Seed Production” provides information relating to commercially cultivable fresh water fishes, broodstock management, fish seed production technology, fish seed quality management including induced breeding with neat illustration. Increasing the aquaculture production can be achieved through the supply of quality fish seed. This book will be immensely helpful to farmers, hatchery managers, entrepreneurs and fisheries graduates pursuing research in the area of freshwater broodstock management and sustainable development of freshwater aquaculture in the country.

Seventy-two pairs of channel catfish Ictalurus punctatus were induced to spawn in glass aquaria by injecting fish pituitary into the females. Control of peritoneal lesions, infections, and adhesions, was anticipated by including 10,000 unites of crystalline penicillin-G with each injection. Spawning was induced by injecting acetone-dried pituitaries from carp, buffalofish, flathead and channel catfish, and gar. Pituitaries from these various species differed little, regardless of time of collection. The amount of pituitary material required to induce spawning varied from 3 to 32 milligrams per pound of fish weight, given in from 1 to 28 injections, with an average of 3. Most females required 3 injections at 2 milligrams per pound of body weight every 24 hours. The period of time from the last injection to spawning varied from 2 1/2 hours to 72 hours, but averaged 16 to 24 hours.
