Download or read book Welfare of Cultured and Experimental Fishes written by Pablo Arechavala-Lopez and published by MDPI. This book was released on 2019-11-18 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welfare is a multidimensional concept that can be described as the state of an animal as it copes with the environment. Captive environments can impact farmed animals at different levels, especially fishes, considering their highly complex sensory world. Understanding the ethology of a species is therefore essential to address fish welfare, and the interpretation of behavioral responses in specific rearing contexts (aquaculture or experimental contexts) demands knowledge of their underlying physiological, developmental, functional, and evolutionary mechanisms. In natural environments, the stress response has evolved to help animals survive challenging conditions. However, animals are adapted to deal with natural stressors, while anthropogenic stimuli may represent stressors that fishes are unable to cope with. Under such circumstances, stress responses may be maladaptive and cause severe damage to the animal. As welfare in captivity is affected in multiple dimensions, multiple possible indicators can be used to assess the welfare state of individuals. In the past, research on welfare has been largely focusing on health indicators and predominantly based on physiological stress. Ethological indicators, however, also integrate the mental perspective of the individual and have been gradually assuming an important role in welfare research: behavioral responses to stressors are an early response to adverse conditions, easily observable, and demonstrative of emotional states. Many behavioral indicators can be used as non-invasive measurements of welfare in practical contexts such as aquaculture and experimentation. Presently, research in fish welfare is growing in importance and interest because of the growing economic importance of fish farming, the comparative biology opportunities that experimental fishes provide, and the increasing public sensitivity to welfare issues.

Download or read book Aquaculture Water Reuse Systems Engineering Design and Management written by M.B. Timmons and published by . This book was released on 1994-10-25 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for high quality aquacultured products and an increasing concern for resource conservation has led individuals and large corporations to invest time and money in commercial scale recirculating production systems. However, there are relatively few reports of profitable recirculating production systems in operation. There is little doubt that most fish reared in ponds, floating net pens, or raceways can be produced in commercial scale recirculating systems. The objective of this book is to provide basic information and analytical skills for the reader so that they may make the proper design or investment decisions concerning water reuse and recycle systems. The chapters of this book are sequenced to provide continuity to a basic approach that would be used in designing a water reuse or recycle system. The chapter authors contributing to this book have written extensively in the literature already on the particular subject being addressed in their chapter. Considerable background information on the basic processes being presented is also given in each chapter to supplement the basic design information being provided. These chapters should provide the reader with essentially all the information required in order to design and manage a water reuse system. The book is written for engineers and biologists working in the area of intensive fish culture. The text should also prove useful as a design manual for practising aquaculturists and as a resource of current "state-of-the-art" methodologies associated with water reuse systems.

Download or read book Modeling and Control of Greenhouse Crop Growth written by Francisco Rodríguez and published by Springer. This book was released on 2014-11-01 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion of challenges related to the modeling and control of greenhouse crop growth, this book presents state-of-the-art answers to those challenges. The authors model the subsystems involved in successful greenhouse control using different techniques and show how the models obtained can be exploited for simulation or control design; they suggest ideas for the development of physical and/or black-box models for this purpose. Strategies for the control of climate- and irrigation-related variables are brought forward. The uses of PID control and feedforward compensators, both widely used in commercial tools, are summarized. The benefits of advanced control techniques—event-based, robust, and predictive control, for example—are used to improve on the performance of those basic methods. A hierarchical control architecture is developed governed by a high-level multiobjective optimization approach rather than traditional constrained optimization and artificial intelligence techniques. Reference trajectories are found for diurnal and nocturnal temperatures (climate-related setpoints) and electrical conductivity (fertirrigation-related setpoints). The objectives are to maximize profit, fruit quality, and water-use efficiency, these being encouraged by current international rules. Illustrative practical results selected from those obtained in an industrial greenhouse during the last eight years are shown and described. The text of the book is complemented by the use of illustrations, tables and real examples which are helpful in understanding the material. Modeling and Control of Greenhouse Crop Growth will be of interest to industrial engineers, academic researchers and graduates from agricultural, chemical, and process-control backgrounds.
