As aquaculture continues to grow at a rapid pace, understanding the engineering behind aquatic production facilities is of increasing importance for all those working in the industry. Aquaculture engineering requires knowledge of the many general aspects of engineering such as material technology, building design and construction, mechanical engineering and environmental engineering. In this comprehensive book, Odd-Ivar Lekang introduces these principles and demonstrates how such technical knowledge can be applied to aquaculture systems, offering the reader coverage including: ac Construction and design of aquatic production facilities ac Water transportation and treatment ac Different production units ac Feed and feeding systems ac Instrumentation and monitoring ac Fish transportation and grading ac Cleaning and waste handling Fish farmers and other personnel involved in the aquaculture industry, suppliers to the fish farming business and designers and manufacturers will find this book an invaluable resource. The book will be an important addition to the shelves of all libraries in universities and research institutions where aquaculture, agriculture and environmental sciences are studied and taught.Figure 19.16 A monitoring system comprises three major parts: the sensors, the monitoring centre and the warning equipment. ... as monitoring points in the alarm system can be used.20 Sensors can be used to control water level, water flows or water quality parameters, all described earlier in this chapter. ... To illustrate the functioning of a PLC, take a simple monitoring system on a farm as an exampleanbsp;...
