The dominant species in the Caspian Sea fishery
are Beluga, Osetra and Sevruga. Other fisheries are the Black
Sea (-1,000 tons), Siberian freshwater bodies (-100 tons) and
Amur River (-70 tons). The Amur is the only place in the world
inhabited by Kaluga sturgeon. Figure 8-6.

The dynamics of the sturgeon fisheries in the Caspian
Sea can be seen in Table 8-4. The decline in the valuable Beluga
catch may signal bad news for the sturgeon caviar indus-try. The
decline in the sturgeon commercial fishery in B.C. can be seen
in Table 8-5. Between 50 and 90% of B.C. sturgeon are caught in
the Fraser River, the remainder is a bycatch in salmon gillnet
fisheries. Similar declines can be observed for each and every
Canadian water body where sturgeon were commercially fished in
the past: Nelson River (Manitoba), St. Johns (New Brunswick).
These reported landings do not include sports fishermen's catches
and native food fishing. TABLE 8-4
