References. The snake head of murrels are a group of air breathing fishes which by virtue of the presence of accessory respiratory organ can thrive well in fallow derelict swampy waters normally considered as adverse low oxygen environments condition. Among the different air breathing fishes Channa sp. (murrels) constitute the most common and dominent group. Murrels are highly priced fishes all over the India for their good keeping quality unique flavour nutritive recuperative and medicinal properties especially in Punjab West Bengal M.P. and Peninsular India. This group of fishes constitute the mainstay of natural freshwater fisheries in Peninsular India where they are reared in village ponds irrigation wells and shallow water. Among different murrels which are available in India the giant murrel (Channa marulius) the stripped murrel (C.straitus) and the spotted murrel (C.Punctatus) are important and commonly available species of which the former two attain a large size and are of economic importance. Because of their hardy nature and capacity to thrive in swamp and derelict waters where Indian major carps can not survive murrels have attracted the attention of pisciculturists scientists and planners as a candidate species for culture with minimal investment. The major constraint in their culture is the lack of knowledge about their biology and absence of culture methods is available at present. A sincere attempt has been made in this book to gather information on the bionomics seed resources of three important species of murrels and their culture viability this will be definitely an asset to the farmers scientists and planners alike. 112 pp.…

From the Preface Induced breeding and polyculture of carps are well known technologies being extensively adopted on a large scale in almost all parts of the country. The thrust in aquaculture has led to more demand for quality stocking material. Ever increasing demand of quality seed cannot be met by collection of seed from natural resources i.e. rivers canals etc. Many aquaculturists and agencies those were earlier dependant on natural fish seed collection have switched over to artificial fish seed production in recent years. Since the establishment of Pond Culture Division of Central Inland Fisheries Research Institute at Cuttack in 1949 and presently the Central Institute of Freshwater Aquaculture Bhubaneswar it has made epoch making contributions to R and D in aquaculture in the country. Two major technologies such as induced breeding and composite culture of carps laid the foundations of Indian Aquaculture. CIFA has developed technologies to produce seed for a prolonged duration covering pre and post monsoon months by multiple spawning of carps. This would provide full time employment to the farmers engaged in multiple breeding and thereafter for multiple cropping of table size carps. 164 pp. …

The book is primarily intended to serve as both a text book for the graduate/postgraduate courses and a reference book for researchers teachers and fishery biologists. The teachers particularly those imparting advanced teaching will get contemporary view of the topics they teach. Ichthyology is a much sort after subject of specialisation for students doing post graduation at Indian universities. Lack of up to date comprehensive resource material written by Indian authors is greatly felt and it is one of the factors impending the updating of the syllabi. The book is intended to fill this void. A wide coverage of fish biology will make it of interest not only to ichthyologist but to professional fishery biologist as well desiring to learn basic structure and function of fish body in daily life of the fish. The book will also be found useful in many ways to the large number of candidates who seek to appear at competitive professional examination or face interviews for selection to build their carrier every year. …

The invention of the Polymerase Chain Reaction (PCR) technique by Kary. B. Mullis has revolutionized the field of diagnostic molecular biotechnology. Its ability to detect pathogens at the molecular level has given it an unparalleled stature. Initially restricted to the laboratories now it has found wide application at the field level. This is evident from the present surge in references to the technique. With the plenitude of viral and bacterial epizootics plaguing shrimp aquaculture and remedies for the same being a distant possibility the aquaculture sector as such is opting for newer strategies to keep itself sustainable. One such approach which is gaining momentum is to screen shrimp seeds prior to stocking and broodstocks prior to seed production. How far this approach will contribute in striking a balance between loss and production has been successfully established in recent years in India. The scenario in the aquaculture sector has changed with the popularization of the PCR technique whereby farmers are insisting on PCR tested seeds and hatcheries are not taking risk by using untested broodstocks. PCR the repetitive bi directional DNA synthesis via primer extension of a specific nucleic acid sequence is simple in design and can be applied in seemingly endless ways. Because PCR is much more than just mixing reagents in a tube and running a machine this book outlines the best ways to utilize the PCR technique for shrimp disease diagnosis in particular the white spot syndrome virus (WS8V). Along with detailed protocols it also deals extensively on the effective utilization of laboratory space 111 which PCR procedures are setup and how to avoid PCR contamination by applying a self imposed technical auditing to ourselves. Further this book dealt with other successfully developed and demonstrated molecular techniques viz. in situ hybridization probes and blot techniques etc apart from electron microscopy and cryopreservation protocols. One would find this book a comprehensive write up packed with innovative information and advanced technical know hows essential for undertaking aquaculture in the most modern manner. 166 pp.…
