Some of the most important work is interestingly described in a history of the Bureau of Fisheries issued in 1908. Among other things it tells of the lobster industry in both the Atlantic and Pacific Oceans. Lobsters are not found naturally in the Pacific, but shipments of lobsters have been made from the Atlantic coast. At the last shipment, after carrying them across the continent packed in seaweed, more than a thousand lobsters were safely placed on the bed of the Pacific Ocean. On the Atlantic coast the lobsters were rapidly disappearing when the work of artificial "planting" of young lobsters and eggs began. The results can be seen now, for more lobsters are being caught each year, and the price to users is growing less as the supply becomes more plentiful. The shad and the salmon are considered the finest of all fish for eating. Both are salt-water fish and both have the habit of going some distance up fresh-water rivers to lay their eggs. No eggs are ever laid in salt water. The mother fish goes up beyond where the tide comes in, so that the baby fish may have fresh water, which is necessary for them. Salmon and shad are never caught in the sea, but in the rivers, where they go in large numbers to lay their eggs in the spring. This, of course, means the destruction of both fish and eggs,--the present and future supply. Shad eggs, or roe are sold in large quantities. The Bureau of Fisheries has planted three thousand millions of young shad in streams along the coast, and the eggs from which these fish were hatched were all taken from fish that had been caught for market, and would have been totally lost if the Bureau had not collected them from the fishermen. Shad have been planted in the Sacramento and Columbia Rivers flowing into the Pacific Ocean. From these two sources they have spread until now they are found as far south as Los Angeles, and as far north as Alaska, a coast line of 4,000 miles, and it is said that more shad could now be caught in the Sacramento and Columbia Rivers than in any other water courses. In addition to supplying the streams with young fish, it is necessary to leave a part of each river clear so that some of the fish may find their way up-stream to deposit their eggs. The salmon have been almost driven out from the waters of New England, except in the Penobscot River, where they have been kept by the watchfulness of the Fisheries Bureau. It is believed that the entire salmon industry in Maine would be wiped out in five years if fish culture should cease, and in the West, where the drain on the salmon for canning purposes is so heavy, artificial planting is used very largely to keep up the supply.
