Fish Welfare – Between Regulations, Scientific Facts and Human Perception

Abstract

Farming of fish and other aquatic species has increased in recent decades and never before have there been more controversial debates on animal welfare in fish husbandry. The practices used and associated welfare issues are becoming increasingly focused on by scientists, consumers and policy makers. International and national organisations have issued recommendations and guidelines concerning fish welfare but there is still a lot of information lacking. Due to § 2 of the German animal protection law, animals must be adequately nourished, cared for and behaved in a proper manner, and pain or avoidable suffering or damage must be avoided. Keeping fish in accordance with the animal protection laws should be part of a good professional aquaculture practice and is indispensable for ethical, legal and economic reasons. As other vertebrates fish have the right of a healthy life with physical and mental integrity, under which they can perform adequately. The paper provides and discusses legal aspects of animal protection applied to fish taking the German welfare act and EU regulations as example. First possible indicators for the assessment of well-being will be mentioned. The assessment of fish welfare indicators should be carried out within the frame of daily and regular working routines, e. g. feeding, harvesting, grading or slaughtering. Further customer’s perception and human interpretation of welfare in fish are discussed and set into the context of human sentiments, projected on fish and the debate on consciousness in fish.
