Marine Protected Areas
Black Sea Region
The Black Sea is one of the most
remarkable regional seas in the world.
It is bordered by six countries
(Bulgaria, Romania, Turkey, Georgia,
Russia and Ukraine) and is almost
cut off from the rest of the world's
oceans, The Black Sea waters are
formed from a mixture of fresh water
from Europe’s big rivers and salty
waters from the Mediterranean Sea.
The Black Sea coastline of
Bulgaria is 378 km in length.
There are about 125 fish
species in Black Sea (26 of
them with economic value,
36 of them are protected
ones).
The main fish species represented in the catches are the pelagic ones, which are
situated in high sea and also near to the coast. The most frequent species caught in
the Black Sea are small finfish: sprat, anchovies, horse mackerels and whiting.
Other species which are present, but in lower quantities are: grey mullet, dogfish
and turbot. In addition to these species, Bulgaria has largely developed the
exploitation of an invasive Seasnail, the Rapana (Rapana Venosa).

A list of species, included in the Black Sea Data Book which
inhabit the Bulgarian Black Sea coast-line and in the Bulgarian
Black Sea water area
The list contains as well the IUCN protection status for the species at two levels:
WL – world level;
BSRL – regional level - the Black Sea region
and the protection status according to the Red Data Book (RDB) of Bulgaria.
Abbreviations used in IUCN:

Measures to protect different fish species from over-exploitation are described.
It is concluded that both eutrophication and pollution (with oil products, heavy
metals, chlorine compounds and other contaminants) are increasing in the sea,
and that previous steps to protect fish populations have not yielded the desired
results. The populations of most species have fallen sharply, especially after the
rapid growth of the new ctenophore species Mnemia maccradyi (Mnemiopsis
leidiy). Delays in the prohibition of bottom trawling, which ruined the biotic
communities of the sea bottom and in so doing affected the link between the
benthic and pelagic communities, have also contributed to declines in fish
populations.
