They then went into the hatchery and saw pool after pool so arranged that there was a continuous stream of fresh water running through each one. In some were the eggs. In others there were fish of various sizes. It seemed to Bill that there could not be that many fish in the entire world. The small fish just hatched out were so small that they looked more like young tadpoles than fish. Outside in the racks the salmon were of various sizes, from three feet in length up to four or even five feet. Some of them were tremendous. It was hard to realize that just a few years before these giant fish were as small as the minute wiggly things in the pools in the hatchery.
