black sea red data book - Department of Biology

Sea; in the Atlantic known to occur around the Canary Islands. A decapod with a high
ecological plasticity, relatively resistant to a polluted environment, and to a decrease
in eelgrass beds.
Biology. Carnivorous, eats small fish and shrimp, usually carrion. Highly prolific,
with a long period of reproduction, from May until December. In the period of
reproduction it makes migrations to the shore. Its planktonic larvae (zoea and
megalope) are the most resistant of all decapods of the Black Sea. An eurythermic
and euryhaline species.
Population trends. Up to 1980 it was frequent on the Romanian littoral, after that it
became more rare. A small number of individuals were found during 1991-1995 on
the northern Romanian coasts.
Threats. Anthropic pressures from large-scale coastal hydrotechnical works,
degradation of Zoster a communities.
Conservation measures taken. Included in the Red Data Book of Ukraine, 1994.
Conservation measures proposed Reduce eutrophication.
