Animal Welfare Science

This article aims to use contemporary (terrestrial) animal welfare science as a lens to evaluate the state of knowledge concerning welfare in fish species, focusing on farmed fishes. We take advantage of the vast expertise—including previous pitfalls and accomplishments—in the investigation of welfare in terrestrial vertebrates, borrowing questions and methodologies from terrestrial animal welfare science in order to (1) better understand the challenges and opportunities in the study of welfare in fish species, and (2) propose strategies for filling knowledge gaps.

Survey Results

Integrating welfare principles into conservation strategy is an emerging synthesis that encourages consideration of individual animals’ quality of life in research, policies and law. However, these principles have gained limited traction in marine compared to terrestrial animal conservation. This manuscript investigates several factors that may be contributing to this disparity. In order to gauge current understanding of animal welfare science principles by marine mammal researchers and other stakeholders, a “Welfare in the Wild” workshop was convened at the 32nd European Cetacean Society conference (La Spezia, Italy, April 2018). The workshop was attended by 30 participants who completed pre- and post-workshop surveys on animal welfare principles. The survey results highlight a range of different views about exactly what animal welfare science is and how it can be applied to marine mammals. Specifically, participants’ definitions appeared to vary depending on the type of employment or research they engaged in, indicating a need for an interdisciplinary common language. Secondly, we analysed the peer-reviewed literature in order to ascertain where marine mammal publications exploring welfare were being published. From 1950 to July 2020, a total of 299 articles featured both marine mammal taxa (one or more) and the word welfare in the title, abstract or keywords. This represents just 0.96% of the total peer-reviewed published papers on marine mammal taxa (n = 31,221) during the same period. When examining articles published within “Welfare and Ethics” (n = 6133) and “Aquatic-focused” (n = 139,352) journals, just 1.2% (n = 71) and 0.04% (n = 57) of articles, respectively, featured the word welfare when examining marine mammals. With the aim of exploring how explicitly including welfare evaluations in marine mammal research and management can benefit conservation outcomes, we framed our workshop and quantitative literature review findings to provide practical solutions to the language, translation and reception issues of this burgeoning cross-disciplinary collaboration.

Challenges And Opportunities

Advances in multiscale models and computational power have enabled a broad toolset to predict how molecules, cells, tissues and organs behave and develop. A key theme in biological systems is the emergence of macroscale behaviour from collective behaviours across a range of length and timescales, and a key element of these models is therefore hierarchical simulation. However, this predictive capacity has far outstripped our ability to validate predictions experimentally, particularly when multiple hierarchical levels are involved. The state of the art represents careful integration of multiscale experiment and modelling, and yields not only validation, but also insights into deformation and relaxation mechanisms across scales. We present here a sampling of key results that highlight both challenges and opportunities for integrated multiscale experiment and modelling in biological systems.

AbstractIn this paper we explore the use of multimodal and multilingual semiotic resources in interactions between two deaf signing participants, a researcher and an asylum seeker. The focus is on the use of gaze and environmentally coupled gestures. Drawing on multimodal analysis and linguistic ethnography, we demonstrate how gaze and environmentally coupled gestures are effective semiotic resources for reaching mutual understanding. The study provides insight into the challenges and opportunities (deaf) asylum seekers, researchers, and employees of reception centres or the state may encounter because of the asymmetrical language competencies. Our concern is that such asymmetrical situations may be created and maintained by ignoring visual and embodied resources in interaction and, in the case of deaf asylum seekers, by unrealistic expectations towards conventionalized forms of international sign.

Abstract Established in 2001, the Animal Welfare Assessment Contest® (AWJAC®) aims to be an innovative educational tool for enhancing understanding and awareness of welfare issues affecting animals used for human purposes (e.g., research, agriculture, entertainment, companionship). The contest is open to participation by veterinary, undergraduate, and graduate students who may participate as individuals or as part of a team. A limited number of veterinarians are also eligible to compete as non-placing participants. Participation in the contest entails assessment of live and computer-based scenarios encompassing data, photographs, and videos of animals in comparable situations. Students then use the information obtained to rank the welfare of the animals in those situations on the basis of physiologic and behavioral indicators, with attention to facilities and management, and present their analyses orally to expert judges. The species featured change each year of the contest. At the completion of each contest, participants and coaches are asked to anonymously complete a written survey. The quantitative and qualitative results of this survey are used to determine if the contest has achieved its aims and incorporate suggestions for improvement of future contests. The majority of survey respondents from the five contests held between 2014–2018 report they either strongly agree or agree that the AWJAC increased their knowledge of animal welfare science (98%, n = 549) and was an overall valuable experience (99%, n = 547) that they would recommend to their peers (98%, n = 550). Respondents cited networking opportunities and diversity of species featured in the contest as key reasons the contest is valuable. Given these results, the AWJAC is successfully achieving its aims to increase animal welfare knowledge in an innovative way.

Analgesic Agents

The number of fish used in research has increased in the last decades. Anaesthesia is required when fish must be held immobile and it is crucial to promote fish welfare, because these vertebrates can show signs of stress and/or pain during handling, transport, tagging, sampling and invasive procedures. The use of an inadequate anaesthetic protocol can compromise not only the welfare of the fish, but also the reliability of the research results. Thus, the development of suitable anaesthetic regimes for each fish species is important. This article reviews the main anaesthetic and analgesic agents used in adult fish in a research setting.

Lower Growth

In this study we verified data of water temperatures collected by CORSAN-RS from 1996 to 2004 in several cities of the state of Rio Grande do Sul, southern Brazil, and analyzed the possibility of raising the most cultivated fish species in Brazil. The water temperature from 1996 to 2004 was 16 to 28ºC in summer, 17 to 23ºC in fall, 14 to 17ºC (down to 9ºC in the coldest months) in winter and 14 to 21ºC in spring. Native species of this state, such as silver catfish (Rhamdia quelen), traíra (Hoplias malabaricus), dorado (Salminus brasiliensis), pintado (Pimelodus maculatus), as well as carps (family Cyprinidae), are resistant to the low winter temperatures. These species have a lower growth rate in coldest months (winter/spring) but a good development in warmer months (summer/fall), reaching a satisfactory performance throughout the year. In the periods of more intense cold, mortality of some introduced species, such as surubim from Amazon Basin (Pseudoplatystoma sp.), pirapitinga (Piaractus brachypomus), pirarucu (Arapaimas gigas), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and Nile tilapia (Oreochromis niloticus) may occur. In addition, as most tropical species have a thermal range for growth and reproduction between 20 to 28ºC, some species may have poor development even in fall. Therefore, water temperature in this state should be considered in the choice of fish species to be cultivated.
