Paperback. Condizione: New. Print on Demand. This book delves into the intriguing world of tuna fishing and explores a revolutionary method for attracting and controlling these valuable fish using electrical stimuli. The author, a physicist, investigates the theoretical principles behind electrofishing, meticulously examining th…e distribution of electric fields in seawater and the impact of these fields on fish. Drawing on the early research of Morgan and Tester, the author conducts extensive experiments with the aholehole, a tropical marine fish, to determine the ideal current density, pulse duration, and frequency for inducing electrotaxis. This process involves stimulating the fish to swim towards a specific location through the use of electric currents. The book then moves on to larger fish, particularly tuna, and describes the development and testing of a specialized apparatus capable of producing strong electric fields within a large tank. The author carefully analyzes the results of these experiments, providing valuable insights into the electrotactic response of tuna. The book concludes with a discussion of the potential challenges and opportunities of applying this technology in open ocean environments, highlighting the need for greater power output to compensate for the increased water volume and surface area. This groundbreaking work represents a significant contribution to the field of fisheries research, offering a unique perspective on the behavior of tuna and exploring the potential of electrical stimulation as a more efficient and sustainable approach to fishing. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
