1. A computer-implemented method, comprising:
illuminating, by a fish imaging system that includes
(i) a fish imaging container that includes top, bottom, left and right sides around the fish imaging container that each include a window for viewing fish that swim through the fish imaging container, and
(ii) top, bottom, left and right fish imaging assemblies that are each associated with a respective side of the fish imaging container, and that each include
(a) a camera for viewing, through a window of the fish imaging container, fish that swim through the fish imaging container, and
(b) a pair of lights including a light of a first color and a light of a second color, each for illuminating, through the window of the fish imaging container, fish that swim through the fish imaging container,
a light of the first color in both the top and the bottom fish imaging assemblies;
while the light of the first color is illuminated in both the top and the bottom fish imaging assemblies, controlling an exposure of a camera in both the left and the right fish imaging assemblies to generate left and right images of a particular fish swimming through the fish imaging container;
after the first image is generated, ceasing illumination of the light of the first color in both the top and bottom fish imaging assemblies;
after ceasing illumination of the light of the first color in both the top and bottom fish imaging assemblies, illuminating a light of the first color in both of the left and the right fish imaging assemblies; and
while the light of the first color is illuminated in both the left and the right fish imaging assemblies, controlling an exposure of the camera in each of the top and the bottom fish imaging assemblies to generate top and bottom images of the particular fish swimming through the fish imaging container.
