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. 606 $aBiology, life sciences$2bicssc 610 $aAfrican catfish (Clarias gariepinus) 610 $aage 610 $aaggression 610 $aaggressive interaction 610 $aAmyloodinium ocellatum 610 $aanimal behavior 610 $aaquaculture 610 $aboldness 610 $aDanio rerio 610 $aelevated phosphate concentrations 610 $aethology 610 $afeed efficiency 610 $afertilisation success 610 $afighting ability 610 $afish welfare 610 $afisheries management 610 $aFishEthoBase 610 $afractal analysis 610 $aframework 610 $agrowth 610 $ahematology 610 $ahistopathology 610 $amotivation 610 $amuscle texture 610 $an/a 610 $anegative and positive affect 610 $anociception 610 $apain 610 $aphysiological response 610 $apositive welfare 610 $arisk analysis 610 $aScyliorhinus canicula 610 $asharks 610 $asocial communication 610 $asocial rank 610 $asocial stress 610 $astereotypical behaviour 610 $astress 610 $astructural complexity 610 $aterritorial 610 $awelfare 610 $awelfare criteria 610 $awelfare enhancement 610 $awelfare scores 615 7$aBiology, life sciences 700 $aSaraiva$b Joao$4auth$01314776 702 $aArechavala-Lopez$b Pablo$4auth 906 $aBOOK 912 $a9910367745103321 996 $aWelfare of Cultured and Experimental Fishes$93031954 997 $aUNINA
