This river supports a considerable fishing population, who despatch salt fish and caviare all over Russia.
The chief are the Sardab-rud, Chalus, Herhaz (Lar in its upper course), Babul, Tejen and Nika, and all are well stocked with trout, salmon (azad-mahi), perch (safid-mahi), carp (kupur), bream (subulu), sturgeon (sag-mahi) and other fish, which with rice form the staple food of the inhabitants; the sturgeon supplies the caviare for the Russian market.
As a member of the coterie known as the "Souls" he was, so to speak, caviare to the general.
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.
