The oyster was once hunted so closely that it would have disappeared from our coast waters if the young had not been taken and raised artificially. Is it not interesting to know that we plant young oysters on oyster farms, and raise oyster crops, all below the level of high tide? The greatest oyster farms in the world are upon Chesapeake Bay. There are also oyster farms in other bays upon the Atlantic seaboard, and lately the oyster has been transplanted to the bays upon the Pacific Coast.
The lobster was trapped so industriously that it also began to grow scarce. Finally the government took up the matter of protecting it. The eggs and the young were guarded, and now it is increasing in numbers.
Once the sturgeon was very plentiful in the lakes and rivers of our country. For a long time it was thought to be of no value and was thrown away when caught in nets set for other fish. Then it was discovered that its flesh was delicious, and its eggs, known as caviar, became a very fashionable dish. After this there followed a period of most destructive fishing, and now sturgeon are quite scarce and high priced.
Herring, shad, and salmon are migratory fish. By this we mean that they spend a part of their lives in the ocean but enter the bays and streams at the spawning season. You can readily understand that if the bays are blocked with nets the fish cannot reach the spawning grounds and their numbers must decrease. Chesapeake Bay contains such a maze of nets, many of them extending out ten miles from the shore, that it is a wonder that any fish get past them.

A fish wheel on the Columbia River, in which salmon are caught on their way to the spawning grounds.
The waters of New England were once filled with striped bass, smelt, salmon, and shad, but now these fish are almost gone. The shad are rapidly decreasing all along the Atlantic Coast. The nets in Lake Erie extend out sometimes ten miles from shore, and the whitefish as well as the sturgeon have been greatly reduced in numbers there.
When the Pacific Coast was first settled, the "salmon run" in the Sacramento, Columbia, and other rivers was a wonderful sight. The waters were fairly alive with these huge fish. Hydraulic mining so muddied the waters of the Sacramento that their numbers greatly decreased. Then came the fishermen and stretched their nets across the rivers, so nearly blocking the channels that the salmon were rarely seen on their old spawning grounds. Now salmon fishing is carefully regulated and salmon are increasing.
