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 Artificial Reproduction and Pond Rearing of the African Catfish Clarias Gariepinus in Sub Saharan Africa written by Gertjan de Graaf and published by Conran Octopus. This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manual is based on the practical experiences of the authors on the artificial reproduction and pond rearing of the African catfish Clarias gariepinus within FAO field projects in the Central African Republic, the Republic of the Congo, Kenya and Nigeria. The manual is divided into five major sections dealing with: 1) general biology, including natural feeding habits and reproduction; 2) artificial reproduction, including induced propagation without and through hormone injection; 3) fry nursing in earthen ponds, including pond preparation, fertilization, feeding and management; 4) monoculture, including feeding methods; and 5) polyculture with Tilapia. In addition, information is provided concerning the economics of different fingerling and grow-out farming practices in Africa, and concerning diseases and hybridization.
