In the Volga section of the Caspian Sea fish are caught to the value of about £I,000,000 annually; in the Ural section over 40,000 tons of fish and nearly 1500 tons of caviare are obtained.
As a member of the coterie known as the "Souls" he was, so to speak, caviare to the general.
The fish of greatest economic value are sturgeon (four species), which yield great quantities of caviare and isinglass, the herring, the salmon and the lobster.
The fishery products, including oysters, tarpon, sturgeon,caviare and sponges, are also important.
Fishing off the mouth of the Volga gives occupation to 50,000 persons; the fish, chiefly herrings and sturgeon, together with the caviare prepared from the latter, are sold for the most part at Nizhniy-Novgorod.
