In the water with white sharks (Carcharodon carcharias): participants' beliefs toward cage-diving in Australia
Contributor(s):: Apps, K., Dimmock, K., Lloyd, D., Huveneers, C.
White shark (Carcharodon carcharias) cage-diving tourism is a controversial activity that provokes emotional and often opposing points of view. With increasing demand for shark tourism since the 1990s, the underlying determinants driving this growth in participation remain unclear. This paper...

How smart are fish? Integrating what scientists and fishers know
To Eat or Not to Eat, that is the Question on Class Pets: Michael Paoli at TEDxNavesink
Contributor(s):: Michael Paoli
Remember being bored in school? Don't you wish you could pick vegetables in the hallway and eat them on the way to your next class? Did you ever consider eating your class pet in 7th grade? In this talk Math teacher Michael Paoli shows how an aquaponics fish tank in a New York City public...

Does environmental enrichment promote recovery from stress in rainbow trout?
Contributor(s):: Pounder, K. C., Mitchell, J. L., Thomson, J. S., Pottinger, T. G., Buckley, J., Sneddon, L. U.
The EU Directive on animal experimentation suggests that all protected animals should have enrichment to improve welfare yet relatively little research has been conducted on the impact of enrichment in fish. Studies employing enrichment in zebrafish have been contradictory and all fish species...
Determining the effects of duration and recency of exposure to environmental enrichment
Contributor(s):: Bergendahl, I. A., Salvanes, A. G. V., Braithwaite, V. A.
Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of...
Late summer movements by giant Canada geese in relation to a September hunting season

Why did the fish cross the tank? Objectively measuring the value of enrichment for captive fish
Contributor(s):: Sullivan, M., Lawrence, C., Blache, D.
There has been very little research into the enrichment preferences of ornamental fish, even though there are billions of fish kept in captivity as pets and research animals. We used preference and motivational testing to compare the value of real and artificial plants to goldfish ( n=20,...
On-farm evaluation of the Salmon Welfare Index Model (SWIM 1.0): theoretical and practical considerations
Contributor(s):: Folkedal, O., Pettersen, J. M., Bracke, M., Stien, L. H., Nilsson, J., Martins, C., Breck, O., Midtlyng, P. J., Kristiansen, T.
The present study investigated the operational feasibility of the recently developed Salmon Welfare Index Model (SWIM 1.0) designed for Atlantic salmon ( Salmo salar L) in production cages. Ten salmon farms containing spring smolts were visited twice, first between May and June the first year in...
Feeding behavior and the effect of photoperiod on the performance and hematological parameters of the pacama catfish ( Lophiosilurus alexandri)
Contributor(s):: Kitagawa, A. T., Costa, L. S., Paulino, R. R., Luz, R. K., Rosa, P. V., Guerra-Santos, B., Fortes-Silva, R.
The aim of this study was to evaluate the rhythms of feeding and locomotor activity, the ability to synchronize to a fixed feeding time, and the influence of photoperiod on the growth parameters, feed intake and hematological parameters of a recently introduced fish in freshwater Brazilian...
Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae
Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.
Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...
Using self-selection to evaluate the acceptance of a new diet formulation by farmed fish
Contributor(s):: Carlberg, H., Cheng, Ken, Lundh, T., Brannas, E.
The evaluation of new diet composition is commonly achieved by performing time-consuming growth trials, which may negatively impact the welfare of a large number of fish if the feed is not accepted. Instead, the fish's behavioural responses to a new diet composition can be used as a first step in...
A test of "nutritional wisdom" in perch ( Perca fluviatilis) by self-selection of encapsulated macronutrients
Contributor(s):: Brannas, E., Strand, A.
Developing optimal diets based on fish macronutrient requirements is an expensive and laborious task requiring years of research. However, many species of fish can compose a species-specific optimal diet from single source macronutrients in capsules through self-selection. Eurasian perch is a...
Isolation impairs cognition in a social fish
Contributor(s):: Brandao, M. L., Braithwaite, V. A., Goncalves-de-Freitas, E.
In variable environments, animals can learn to alter their behavior to adjust to changes. Sometimes, however, this learning ability can be impaired. For example, challenges in the social or physical environment can trigger physiological responses that compromise an individual's capacity to learn...
A "how-to" guide for designing judgment bias studies to assess captive animal welfare
Contributor(s):: Bethell, E. J.
Robust methods to assess nonhuman animal emotion are essential for ensuring good welfare in captivity. Cognitive bias measures such as the judgment bias task have recently emerged as promising tools to assess animal emotion. The simple design and objective response measures make judgment bias...
Certification standards for aquaculture products: bringing together the values of producers and consumers in globalised organic food markets
Contributor(s):: Bergleiter, S., Meisch, S.
From a certifier's perspective (Naturland e.V.), this paper deals with the question of how to bring together the values of producers and consumers in globalized food markets. It is argued that growth and mainstreaming of organic food production cannot be achieved solely by ethically aware...
Fish consumption: choices in the intersection of public concern, fish welfare, food security, human health and climate change
Contributor(s):: Rocklinsberg, H.
Future global food insecurity due to growing population as well as changing consumption demands and population growth is sometimes suggested to be met by increase in aquaculture production. This raises a range of ethical issues, seldom discussed together: fish welfare, food security, human...
Consistency in European seabass coping styles: a life-history approach
Contributor(s):: Ferrari, S., Millot, S., Leguay, D., Chatain, B., Begout, M. L.
Recent years have seen a growth of interest in the consistent differences in individual behaviour over time and contexts constituting the so-called "individual coping styles". An understanding of this inter-individual variation is essential to improve our knowledge of the adaptive value of...
