Methodological choices in animal experimentation are influenced by a variety of factors. The analysis of the relative weight of such factors on the practice of animal experimentation can offer a better idea of the influences characterizing the work of researchers today. To this aim, we conducted structured interviews and sent out questionnaires to researchers using animal models. The results showed that the main factor influencing the researchers’ work with animals was the appropriateness of the chosen animal model to respond to the question addressed. Ethical issues came as the next important factor, mostly based on considerations regarding animal suffering. The general public opinion appeared to be of little significance, indicating that a gap still exists between animal researchers and society. This paper shows animal experimentation is influenced by both external (e.g., adherence to scientific objectivity) and internal factors (e.g., ethical concerns), providing a varied profile of the contemporary animal researcher.
‘My fish and I’ is an account of the diversity of human-fish interactions. This includes their benefits, detriments/harms as well as their moral and animal welfare. Fish are not easily perceived as individual animals having mental states, interests, needs and a degree of individuality. Additionally, fish have been handled as a simple resource in innumerable human interactions. Important ethical approaches address animal-human interactions based upon the individual’s cognitive ability and capacity to feel pleasure and pain. Given the ample evidence that fish have neuroanatomical structures that support the capacity to feel (sentience) and have complex behavioural and cognitive abilities, a moral duty is imposed upon us. Some human-centered and eco-centered moral views complement different perceptions of the nature of our relationship with fish. This occurs both at the individual level and as species or populations face a serious need for conservation. The concepts and assessments in the developments of animal welfare science provide ample basis for an evolution in the quality of human-fish interactions. However, many stakeholders must take part in this evolution. This is especially true as it concerns those areas of activity involving many individual fish and higher levels of suffering. Examples of these are aquaculture and commercial fisheries where there is much more at stake. Consumers will have the last word in this role, namely by reducing fish consumption.
