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.

Hardcover. Zustand: New. The present book a new of its kind, dealt with production of galvanic current in water, moist cotton, and soil media to stimulate germination of seeds, growth of seedlings to flower and fruit bearing plants. In different chapters of the book, an outline has been given on the characteristics and present application of galvanic current, factors affecting plant growth, ion exchange in plant roots, soil cation exchange capacity and diffusion process. Electrochemical potential around plant roots in relation to metabolism and growth acceleration has been described elaborately in the relative chapter of the book. Forty one sets of experiments have been carried out for last four years to observe the effect of galvanic current in germination of seeds, growth of seedlings and plants to bear flower and fruits in different growing media. Formation and growth of roots from rhizomes, buds were also investigated. In all twenty variety of seeds, seedlings and plants have been studied during the period. The result of the investigations, indicated that in few majority of cases, the beneficial effect of the influence of galvanic current have been observed in germination of seeds, growth of plants and bearing flowers and fruits, depending on the application of galvanic current, including its magnitude. A comparison has also been made on the effect of galvanic current and externally applied current with respect of germination of seeds. This book will open a new avenue for future research in this regards and will be helpful to teachers, students and research scholars of colleges and universities.
