Sympatric species of threespine stickleback differ in their performance in a spatial learning task

Stimulus-specific development of learning ability during habitat shift in pre to post-recruitment stage jack mackerel

“…In the sympatric stickleback Gasterosteus aculeatus complex, benthic individuals learn to locate hidden food more quickly than pelagic individuals (Odling-Smee et al 2008). Benthic species in a spatially complex habitat may rely on learning spatial information to locate food items and refuges, whereas such tendencies are likely to be fewer for pelagic fish in an open-water area.…”

Welfare assessment of rainbow trout reared in a Recirculating Aquaculture System: Comparison with a Flow-Through System

“…Like mammals, fish are able to associate neutral stimuli to food-rewards (Bratland et al, 2010;Nilsson et al, 2008Nilsson et al, , 2010Yue et al, 2008) or to punishment (Moreira et al, 2004;Yue et al, 2008). Fish are also capable of spatial learning (Braithwaite and de Perera, 2006;Holbrook and de Perera, 2013;Odling-Smee et al, 2008) and show for example increased swimming activity around feeders prior to feeding. This food-anticipatory activity is commonly considered as an indicator of good welfare (Folkedal et al, 2012;Kristiansen and Ferno, 2007;Spruijt et al, 2001) since foraging and feeding motivation may translate a better well-being than prostration.…”

Spatial learning and memory retention in the grey bamboo shark (Chiloscyllium griseum)

“…Kleerekoper et al, 1974;Warburton, 1990;Rodriguez et al, 1994;Salas et al, 1996;Lopez et al, 1999Lopez et al, , 2000Hughes and Blight, 2000;Odling-Smee and Braithwaite, 2003;Odling-Smee et al, 2008) showing that teleosts can apply different orientation strategies, use different spatial memory systems including cognitive spatial maps, and possess neural substrates which are similar if not homologous to the mammalian hippocampus (Lopez et al, 2000;Broglio et al, 2003). Strategies such as turn responses can be used alone or in combination with landmark learning as well as the construction of a cognitive map and can be applied depending on the complexity of the problem.…”
