Hardbound. Condizione: As New. Contents: Preface. 1. Introduction. 2. Environment and organism. 3. Pond bottom treatment. 4. Fish diseases. "To enhance aquaculture production, high stocking rate followed by heavy dose of fertilizers and feed influence the environmental stress factors exceeding acclimation tolerance limits of the cultured stock. As a result the occurrence of frequent fish disease epizootic lead to mortality of fish and decline in fish population.In fact, the production of fish show negative correlation with the environmental stress and disease. The various fish diseases of economic importance identified until now include ulcerative dropsy, columnaries disease, trichodiniasis, white gill spot, white scale spot, dactylogyrosis,black spot, ligulosis, ergasilosis, lernaeosis, argulosis, branchiomycosis and saprolegniasis, have been outlined in the book. Environmental diseases, such as, gas bubble disease, unionised ammonia stress, algal toxicosis, commonly encountered in culture system have been find place in the book. Much stress has been given, in this book, in combating epizootic fish diseases by good husbandry practices and proper monitoring of water quality. "Common shrimp diseases in culture systems and detailed updated informations about viral diseases, particularly, WSBV and WSSV of prawn, causing epidemic in shrimp hatchery and culture systems have been find place in the book. New topics, such as, marine medicines, immune system of fishes to fight diseases, ecomonitoring a measure to prevent stress and disease of fish and prawn, care of acquarium fishes and.…

Soft cover. Condizione: New. As per our previous plan to meet up the aspiration of teachers, students and researchers we are stepping forward to publish another interdisciplinary book covering mainly the different parts of physical and biological sciences. This book is also intended for postgraduate students and young researchers both in Theoretical and Experimental outcomes. We believe that this book will definitely fulfill the expectations of researchers working in related fields in particular. Advancement in applied sciences is a continuous process and it requires high degree of quality and evidence-based research. In this book many recent quality peer reviewed research works and review articles in the related fields are included. Thus the students, research scholars working in the related fields will be definitely benefited. One of the important features of this book is that it is not like a textbook in structure. Again the chapters are written elaborately and such in a lucid manner that even an undergraduate student can grip its benefits. As per the previous book in this series the chapters of this book focus on a wide range of topics from thin films, nanotechnology, microstrip lines, microelectronics to different branches of plant and animal biological sciences mainly food production, SARS CoV 2 to protection of environment, renewable energy and improvement in human health to sustainable protection of our environment in an eco friendly manner and so on. In the very first chapter, a work on structural tuning of BiOCl nano-crystals with PVP modulated visible light stimulated photo catalytic dye degradation process is given. Dispersion analysis of inverted microstrip line in spectral domain and a probe-fed rectangular dielectric resonator antenna (RDRA) with an air gap of rectangular shape by using high frequency simulation software (HFSS) are included in this book.…

Hardcover. Condizione: Fine. Condizione sovraccoperta: Near Fine. 2nd Edition. A highly compressed discussion of both fish and crustacean disease and treatment. Heavy focus on prevention through proper pond prep and water quality maintainance.

Soft cover. Condizione: New. This book is intended for postgraduate students and young researchers. It aims to be helpful to the students of Physical Science, Chemical Science and Biological Science both in Theoretical and Experimental outcomes. The need to advance the field of Applied Science requires high quality, evidence-based research. One of the important features of this book is that it does not have a textbook structure. The chapters are written in a lucid manner so that even a graduate student with a limited knowledge will reap its benefits. The chapters of this book focus on a wide range of topics from thin films, positron annihilation, wire to dot nanostructures, neutrino oscillation, plant regeneration to medicinal plants, double perovskites, Biotinylation Technique and soon.…

Hardcover. Condizione: New. The book, "Five Inventions in Electric Fishing in India" describes how a research endeavour could be nourished for such a long period to find out new ways and means to solve the problems of fish capture with the aid of electric stimulation against all odds and difficulties. Neither sophisticated instruments and equipments for the work was available in the country, nor the trained and knowledgeable personnel to assist in the inventory work. With the available materials and equipments in the country, how the new ways and means have been explored, one after another, to solve the problems. Voices have been raised in many quarters about the illegal and improper use of electricity for fishing, which is not only harmful and causing injuries to fishes, but also has become the cause of fatality to the unauthorized applicators. Proper use under the guidance of qualified and knowledgeable persons, the technique was proved to be very useful for fish capture and less harmful than other fishing gears. The technique of harmless electric fishing described in this book will show a new way of using electric stimulation for mass scale fish capture. The book will be useful for the students and will inspire the research workers.…
