Fish schools

A fish school appears as a mass of echoes on the screen. The color of the mass
shows the density of the fishes and the size of the mass how they are distributed.
In the following figures, the same fish school is observed with two different tilt
angles. From the left figure, the operator can know the horizontal distribution of
the fish school, and from the right figure the vertical distribution.
