Welfare of African catfish : effects of stocking density

P.G. van de Nieuwegiessen

Research output: Thesis › internal PhD, WU

Abstract

The general aim of this thesis was to determine the impact of stocking density on welfare indicators in African catfish, Clarias gariepinus, cultured in a recirculating aquaculture system. The following factors were studied: 1) the effects of stocking density on physical, physiological, and behavioural responses of African catfish, 2) how age mediates the effects of stocking density on physical, physiological, and behavioural responses of African catfish, 3) the potential effects of chemical alarm cues on the welfare of farmed African catfish, and 4) the fitness consequences of different coping strategies in intensive husbandry systems
