Environmental enrichment and prior experience of live prey improve foraging behaviour in hatchery-reared Atlantic salmon (2003, background): “Indeed recent work comparing the brain structure of hatchery- and wild-reared rainbow trout Oncorhynchus mykiss (Walbaum) showed gross differences in brain anatomy and was most pronounced in the telencephalon (Marchetti & Nevitt, 2003).”
The effects of captivity on the morphology of captive, domesticated and feral mammals (2005, background): “Work by Marchetti & Nevitt (2003) has shown that hatchery-reared rainbow trout Oncorhynchus mykiss have significantly smaller brains than those of wild trout.”
Homing and straying by anadromous salmonids: a review of mechanisms and rates (2014, background): “As described in previous sections, reduced stimuli in hatchery fish have been associated with lower hormone levels (Dittman and Quinn 1996; McCormick et al. 2003) as well as lower olfactory activity and reduced brain development (Marchetti and Nevitt 2003) compared to wild fish.”
Effects of predation pressure on the cognitive ability of the poeciliid Brachyraphis episcopi (2005, background): “Similarly, animals that occupy spatially complex environments such as coral reefs also tend to have larger telencephalons (Kotrschal et al., 1988; Marchetti and Nevitt, 2003).”
Environmental enrichment reduces maladaptive risk-taking behavior in salmon reared for conservation (2011, background): “Recent evidence also indicates that artificially-reared fish can have smaller brains and lower cognitive abilities than their wild counterparts (Marchetti and Nevitt, 2003; Kihslinger and Nevitt, 2006).”
Impacts of domestication on angling vulnerability of common carp, Cyprinus carpio: the role of learning, foraging behaviour and food preferences (2013, background): “Second, the holding of domesticated fish in artificial conditions might reduce the ability of these fish to learn complex tasks (Marchetti & Nevitt 2003).”
9 Pathways to Animal Domestication (2012, background): “Even captive-reared fish like rainbow trout (Oncorhynchus mykiss) show significant reduction in brain size compared with wild trout, especially in the areas of the brain linked to aggression, feeding behavior, and reproduction (Marchetti and Nevitt 2003).”
Fine-Scale Behavioral Responses of Pacific Salmonid Smolts as They Encounter Divergence and Acceleration of Flow (2005, unknown): “1984 ; Kennedy et al. 1984 ; Marchetti and Nevitt 2003 ).”
