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 presents comprehensive account of works done so far on basic and applied aspects of edible Mushrooms in simple and lively style for better perception of the readers even without any background knowledge of biology. It includes morphological characteristics of 568 edible mushroom taxa along with their synonym, common name, ecological notes and distribution besides the live photographs of 120 taxa in their natural colour. Identification of the poisonous mushrooms, cultivation methods, culture of mycelia, harvesting, post harvest management and marketing have been discussed with full coverage. Diseases and their control measures have been adopted for extending shelf life of mushroom described along with stepwise method for preparing value added mushroom products.…

Hardcover. Zustand: New. 2nd Edition. The textual contents deal with the existent natural diversity amongst algae and emphasize the necessity of generating reliable ecological and physiological database for their optimum utilization in human welfare. Different aspects of cyanobacterial ecology including their symbiotic relationship, enduring desiccation, tolerating heavy metal and salt stress and allelopathic interactions have been comprehensively discussed. Biomonitoring and bioremediation of an aquatic ecosystem using algae has emerged as an economical and reliable method. Overviews on the interesting Prochlorophyta, biology of the genus Stigeoclonium, morphogenesis of tapered cynobacteria, polymorphism in Desmids, perspective in conjugation in Zygnemataceae, and morphology, cytotaxonomy and evolution of some oogamous green algal groups like Oedogoniales and Charaes, are aimed at providing relevant information to those dealing with basic Phycology.

Hardcover. Zustand: New. 1st Edition. The book entitled "Documentary of Agaricomycetous Mushrooms of India" provides updated compilation of basic data and information on 1920 mushroom taxa belonging to 207 genera spread over 35 families and 3 orders of fleshy fungi published till date from India. The broad classification adopted for compilation of this treatise is largely based on the latest version of the Dictionary of Fungi authored by Kirk et al. (2008). In this documentary the Orders, Families, Genera and Species are arranged in alphabetic order under respective taxonomic category. For a particular taxon, the name of the class, order, family, respective authority and citation has been given as per authentic information available in the MycoBank and Index Fungorum. For every species and variety listed under respective genus, the exact information about the state of its occurrence and the documenting author has been provided. At the end of the documentary the references, which appeared in the main body of the manuscript are listed in an alphabetical order. This data base is likely to set the tone for more explorative work and will provide a significant base line. The gilled and poroid mushrooms embrace diverse and fascinating arrays of fleshy fungi. They are of great interest because of their relevance in nutritional and neutraceutical aspects, mycorrhizal association with plants, and as saprophytes and parasites. This book will be of interest to diverse group of users and we understand clearly that there may have been some inadvertent omissions in our compilation. …
