Application of fluorescent protein transgenesis has commercial use for the ornamental aquarium trade by creating new colour phenotypes in various species. To determine the potential for transgenic ornamental aquarium fish to overwinter in Canada, the minimum temperature tolerance of albino rainbow shark (Epalzeorhynchos frenatum (Fowler, 1934)) was estimated to complement a previous study examining cold tolerance of zebrafish (Danio rerio (Hamilton, 1822)), black tetra (Gymnocorymbus ternetzi… 
Fluorescent protein transgenesis has varied effects on behaviour and cold tolerance in a tropical fish (Gymnocorymbus ternetzi): implications for risk assessment
Fluorescent protein (FP) transgenesis is used in the ornamental aquarium trade to produce new colour morphs in tropical fish. Understanding whether such genetic modification could alter ability to

Low-temperature tolerances of tropical fish with potential transgenic applications in relation to winter water temperatures in Canada
Both tetra and barb had lower temperature tolerance limits that were higher than surveyed winter temperatures in Canada, and the lower tolerance limits of zebrafish lines was only within the range of a few surveyed lakes in some years.
Temperature Tolerances of Wild-Type and Red Transgenic Zebra Danios
The temperature tolerances would classify both varieties of zebra danios as eurythermal and place this species in the relatively rare category of fishes with a CTMax above 40.0°C.
Field Confirmation of Laboratory-Determined Lower Temperature Tolerance of Transgenic and Wildtype Zebra Danios, Danio Rerio
These field results corroborate laboratory findings that the lowest temperature that these two varieties of D. rerio can survive is about 5 C, and confirm that the natural climate of north Texas is suitable for these fish.
Risk Screen of Freshwater Tropical Ornamental Fishes for the Conterminous United States
AbstractThe trade in ornamental fish is increasingly viewed as a major source for the introduction of invasive species into the environment. However, few ornamental fishes are established and
Landscape-scale survey of non-native fishes near ornamental aquaculture facilities in Florida, USA
Few ornamental fishes have established in this region despite a long period of extensive culture, and the observed fish distribution might be due to relatively cold water in sub-tropical Florida, predatory fish in the environment, and additional factors related to the physical or biological habitat.
Low social status impairs hypoxia tolerance in rainbow trout (Oncorhynchus mykiss)
Data indicate that chronic social stress impacts the ability of trout to respond to the additional, acute stress of hypoxia, and chronic behavioural stress resulting from low social status affected the physiological responses of rainbow trout to a subsequent acute stressor.
Chronic social stress impairs thermal tolerance in the rainbow trout (Oncorhynchus mykiss)
It is concluded that social stress impacts the ability of fish to respond, on a cellular scale and in a tissue-specific manner, to increases in water temperature, with likely consequences for overall fitness.
Physiological Causes and Consequences of Social Status in Salmonid Fish1
Abstract Social interactions in small groups of juvenile rainbow trout (Oncorhynchus mykiss) lead to the formation of dominance hierarchies. Dominant fish hold better positions in the environment,
Stress caused by social interaction and its effect on susceptibility to Aeromonas hydrophila infection in rainbow trout Salmo gairdneri
Juvenile rainbow trout were exposed slmultanously to social stress and to infection by the opportunistic ubiquitous bacterium Aeromonas hydropma and subordinate fishes showed enhanced ventdation frequency, elevated plasma glucose level, and increased leucocyte volume as an indication of the stress syndrome.
