We investigated the mechanisms and functions of shoal choice in relation to nutritional state in the zebrafish. Single fish that had been well fed or food deprived for 2 days were presented with a choice between two stimulus shoals. Food-deprived test fish showed a significant preference for well-fed stimulus fish over food-deprived ones whereas well-fed test fish did not exhibit any significant preference. Subsequent experiments showed that food-deprived test fish had a significantly higher… 
Shoal choice in zebrafish, Danio rerio: the influence of shoal size and activity
The influence of shoal activity on shoal size preference in the zebrafish is investigated and it is found that test fish generally preferred the larger shoal, however, this preference could be reduced by presenting the larger Shoal in colder water and so reducing its activity.
Effects of nutritional state on the shoaling tendency of banded killifish, Fundulus diaphanus, in the field
It is concluded that nutritional state seems to affect an individual's decision to continue shoaling once an association has been made, and experimentally state-dependent changes in the size of social groups in fish under field conditions are investigated.
Effects of Food Deprivation Duration on the Behavior and Metabolism of Black Rockfish (Sebastes schlegelii)
Fish often undergo food shortages in nature, especially for juveniles that are relatively vulnerable in most aspects. Therefore, the effects of food deprivation on fish behavior and physiology are
The effect of starvation on taste preferences and testing behavior of food items in the carp Cyprinus carpio
It is assumed that the decrease or complete loss in fish of the negative reaction to substances, initially having aversive taste properties may be considered as the main mechanism providing expansion of the feeding spectrum and/or transfer of fish onto consumption of new items, initially consumed just occasionally or fully avoided.
Effects of Early Embryonic Ethanol Exposure on Adult Zebrafish Social Behavior
It was found that zebrafish exposed to low doses of ethanol at 24 hours post-fertilization do not demonstrate robust differences in preference for yellow or red-coloureded fish images over control images.
The influence of nutritional state on individual and group movement behaviour in shoals of crimson-spotted rainbowfish (Melanotaenia duboulayi)
It is shown that the internal nutritional state of individual fish affected basic behaviours relating to spatial positioning, and group behaviour reflected the motivations of its individual members in such a way that allowed individuals to fulfil their own behavioural needs whilst still attaining the benefits of grouping.
Chemicals Weaken Shoal Preference in the Rare Minnow Gobiocypris rarus
Results showed that single rare minnow preferred shoals over blank control tanks, and this preference was most stable when the shoal was well-fed and contained 20 individuals of 2 cm long.
Diet, familiarity and shoaling decisions in guppies
The relationship between metabolic rate and sociability is altered by food-deprivation
The lack of a link between SMR and sociability in food-deprived fish suggests that, in situations where group membership is linked to fitness, the extent of correlated selection on metabolic traits may be context-dependent.
Nutritional state influences shoaling preference for familiars.
