“…This finding highlights the need to examine more reward types than just food and other consumables. With the exception of studies using water or juice (Richards et al, 1997; Kim et al, 2008; Pearson et al, 2010), we know virtually nothing about how animals trade-off other types of rewards (but see Shapiro and Jensen, 2009). Food is an easy and salient reward type to manipulate, but animals make decisions over many other currencies.…”

“…Fish are a particularly good system for studying spatial choices because numerical discrimination and spatial distances have been tested in a number of species (Tegeder and Krause, 1995; Agrillo et al, 2007; Buckingham et al, 2007; Shapiro and Jensen, 2009). We tested guppies because they must make choices about both food and shoaling partners.…”

In temporal discounting, animals trade off the time to obtain a reward against the quality of a reward, choosing between a smaller reward available sooner versus a larger reward available later. Similar discounting can apply over space, when animals choose between smaller and closer versus larger and more distant rewards. Most studies of temporal and spatial discounting in non-human animals use food as the reward, and it is not established whether animals trade off other preferred stimuli in similar ways. Here, we offered female guppies (Poecilia reticulata) a spatial discounting task in which we measured preferences for a larger reward as the distance to it increased relative to a closer but smaller reward. We tested whether the fish discounted reward types differently by offering subjects either food items or same-sex conspecifics as rewards. Before beginning the discounting tasks, we conducted validation tests to ensure that subjects equally valued the food and social stimuli in the quantities provided. In the discounting task, subjects switched their preferences from the larger to the smaller reward as the distance to the larger reward increased (spatial discounting), but the pattern and magnitude of discounting did not differ across the two reward types. These findings indicate that guppies show similar patterns of discounting for food and social rewards in a spatial task. In an examination of travel times, however, the fish swam faster to food rewards than to shoaling partners. Analysis of travel times suggests that fish temporally discounted social rewards less steeply than food rewards. Thus, reward type influences temporal discounting, suggesting a dissociation between temporal and spatial discounting. Our results illustrate how animals adjust choices and travel times depending on both the type of cost (time, distance) and benefits (food, social partners).

“…On the other hand, in rodent models, both social defeat and chronically social stressed rats showed impaired performance in T-maze suggesting the test is sensitive to stress and suitable for assessing cognitive functions ( Ferragud et al, 2010 ; Novick et al, 2013 ). In addition, the T-maze apparatus is also used in other teleost fish model including common carp ( Cyprinus carpio ; Garina et al, 2016 ), killifish ( Kryptolebias marmoratus ; Rossi and Wright, 1953 ), mangrove rivulus ( Kryptolebias marmoratus ; Chang et al, 2012 ), Port Jackson sharks ( Heterodontus portusjacksoni ; Byrnes et al, 2016 ), goldfish ( Romaguera and Mattioli, 2008 ; Facciolo et al, 2011 , 2012 ), grey bamboo shark ( Chiloscyllium griseum ; Schluessel and Bleckmann, 2012 ), ornate wrasses ( Thalassoma pavo ; Zizza et al, 2017 ), mosquitofish ( Vinogradov et al, 2021 ), Siamese fighting fish ( Betta splendens ; Craft et al, 2003 , 2007 ; Shapiro and Jensen, 2009 ), Girardinus falcatus ( Bisazza et al, 2001 ), guppy ( Miletto Petrazzini et al, 2017 ) for different purposes such as learning test, lateralization and decision-making study. T-maze is an apparatus with great flexibility for assessing cognitive functions and the performance is sensitive to stress exposure, thus, should be incorporated in future social stress study as one of the behavioural parameters.…”

Stress is an important aspect of our everyday life and exposure to it is an unavoidable occurrence. In humans, this can come in the form of social stress or physical stress from an injury. Studies in animal models have helped researchers to understand the body’s adaptive response to stress in human. Notably, the use of behavioural tests in animal models plays a pivotal role in understanding the neural, endocrine and behavioural changes induced by social stress. Under socially stressed conditions, behavioural parameters are often measured physiological and molecular parameters as changes in behaviour are direct responses to stress and are easily assessed by behavioural tests. Throughout the past few decades, the rodent model has been used as a well-established animal model for stress and behavioural changes. Recently, more attention has been drawn towards using fish as an animal model. Common fish models such as zebrafish, medaka, and African cichlids have the advantage of a higher rate of reproduction, easier handling techniques, sociability and most importantly, share evolutionary conserved genetic make-up, neural circuitry, neuropeptide molecular structure and function with mammalian species. In fact, some fish species exhibit a clear diurnal or seasonal rhythmicity in their stress response, similar to humans, as opposed to rodents. Various social stress models have been established in fish including but not limited to chronic social defeat stress, social stress avoidance, and social stress-related decision-making. The huge variety of behavioural patterns in teleost also aids in the study of more behavioural phenotypes than the mammalian species. In this review, we focus on the use of fish models as alternative models to study the effects of stress on different types of behaviours. Finally, fish behavioural tests against the typical mammalian model-based behavioural test are compared and discussed for their viability.

Place versus response learning in fish: a comparison between species

26Place learning is thought to be an adaptive and flexible facet of navigation. 27Due to the flexibility of this learning, it is thought to be more complex than the 28 simpler strategies such as learning a particular route or navigating through the 29 use of cues. Place learning is crucial in a familiar environment as it allows an 30 individual to successfully navigate to the same endpoint, regardless of where 31 in the environment the journey begins. Much of the research to date focusing 32 on different strategies employed for navigation has used human subjects or 33 other mammals such as rodents. In this series of experiments, the spatial 34 memory of four different species of fish (goldfish, killifish, zebrafish and 35Siamese fighting fish) was analysed using a plus maze set-up. Results 36 suggest that three of the species showed a significant preference for the 37 adoption of a place strategy during this task whereas zebrafish showed no 38 significant preference. Furthermore, zebrafish took significantly longer to learn 39 the task than the other species. Finally, results suggest that zebrafish took the 40 least amount of time (seconds) to complete trials both during training and 41 probe. 42
