DOWNLOAD EBOOKThis document is directed to aquaculture development specialists, coastal resource use planners and government officials involved and interested in the planning and management of coastal aquaculture development within the wider context of resource use in coastal areas. It is intended to serve in the promotion of environmental management of coastal aquaculture. Guidelines are given for improved environmental management of coastal aquaculture based on an overview of selected published experiences and concepts. Potential adverse environmental effects of and on coastal aquaculture practices are addressed with consideration of main socio-economic and bio-physical factors. Methodologies are presented for the assessment and monitoring of environmental hazards and impacts of coastal aquaculture. Selected environmental management options are described for application both at policy-level and farm-level.

DOWNLOAD EBOOKThis manual deals with the methods of freshwater fish culture in undrainable ponds as practised in India. The manual is primarily meant for extension workers and aquaculture training institutions. It outlines the basic principles of fish culture and the characteristics of undrainable ponds. The systems of composite carp culture and composite carp culture-livestock farming have been described. Methods of improvement of existing ponds and construction of new ponds have been included. The suitable species for culture, procurement of their seed, stocking ratios of various species under composite culture, etc., have been discussed. Pond management, both pre-stocking and post-stocking, including fish health management and management of common hazards have been dealt with. It also contains information on marketing and economics of fish culture in undrainable ponds.

DOWNLOAD EBOOKThis book describes in general how the chemosensory systems of fish function at various levels. In many ways, fish are typical vertebrates differing only slightly from other vertebrates including humans. In other ways, their aquatic environment imposes strict requirements or offers unique opportunities which have resulted in some unusual functions having no counterpart in higher vertebrates. This new volume is necessitated by advances in many vital areas as the field of chemical senses continues to grow at a rapid pace. Most significant is the application of the contemporary electrophysiological technique of patch-clamping, recognition of a second messenger system in chemosensory transduction processes and the identification of hormonal pheromones in fish reproductive behaviour. The last major synthesis of our knowledge about fish chemoreception, Chemoreception in Fishes, was published ten years ago (Elsevier, Amsterdam, 1982). In that volume four aspects of fish chemoreception, Le. morphology of the peripheral chemoreceptors. primary sensory processes, roles in behaviour, and its interactions with environment, were discussed. This book is intended to be helpful to students, scientists and aquacul turists not only as a source book but also as a textbook on chemical senses.
