Conditioned Reinforcement in the Goldfish
Science, 1968Goldfish were trained to press a lever on a 10:1 fixed-ratio schedule of reinforcement. They were extinguished under three conditions. Responding was followed by (i) solenoid noise and water delivery formerly associated with food reinforcement, (ii) solenoid noise only, or (iii) nothing.

The innervation of the pituitary gland of Carassius auratus was studied by light and electron microscopy under various physiological and experimental conditions to investigate whether or not neurosecretory fibres play a role in regulating pars distalis function. Two types of neurosecretory fibre (Type A and Type B) were distinguished.

Abstract Cinephotographic analysis of eye movement in free swimming fish revealed a basic repeated pattern of (a) conjugate saccade in direction of turn; (b) body turn coupled with a slow counter slewing of eyes at a velocity consistent with stabilization of visual field. Independent eye movement was rare, observed only in Monacanthus sp .

The lure of my own comfortable bed fought against the pandemonium of the emergency room. I acquiesced when I realized I could not swallow my own saliva, the physician in me finally, briefly, surfacing.

Tectotectal connectivity in goldfish
The Journal of Comparative Neurology, 1999The vertebrate optic tectum is a functionally coupled bilateral structure which plays a major role in the generation of motor commands for orienting responses. However, the characteristics of the tectotectal connectivity are unknown in fish, and have been reported only to a limited extent in other vertebrates.

Reward and Learning in the Goldfish
Science, 1967An experiment with goldfish showed the effects of change in amount of reward that are predicted from reinforcement theory. The performance of animals shifted from small to large reward improved gradually to the level of unshifted large-reward controls, while the performance of animals shifted from large to small reward remained at the large-reward ...

In the Goldfish crackers animated commercial series, the main character, Gilbert, is gone. The unfortunate cracker character was sucked up by a vacuum cleaner. But with the help of friends, Gilbert embarks on a new adventure and finds himself "In the Dark," but not alone.

Temporal discrimination in the goldfish
The Journal of the Acoustical Society of America, 1982The capacities of the goldfish to detect changes in sound burst repetition rate were studied using classical respiratory conditioning. In experiment I, the just detectable amount of an instantaneous random jitter of burst period was measured as a function of mean period.

Colour discrimination in goldfish
Animal Behaviour, 1966Summary Goldfish were trained to discriminate between blue, green, and red painted panels, which varied greatly in brightness. The stimuli were chosen in such a way that the discriminations could not be solved in terms of brightness. All the discriminations were easily learnt by the fish, in spite of the large brightness differences.
