3.B.1.1.e Summary table by ecological category of resource (exploitable species)
Resource category State of stocks Ecological/ environmental controls Fisheries management measures Operational targets
Rapana snail Overexploited in Turkey and Bulgaria; some potential in Romania Well adapted to eutrophic conditions Fishery has apparently been prohibited in Turkey Important export market will require steady supply

Because of 1), it is suggested that national management plans be prepared for this single species fishery, and coordinated regionally. It could also be beneficial to have a common international marketing facility for this and other black sea species: (cost of developing such plans, implementation: $120,000: begin before 2000)

Mya clam Unexploited; large biomass in some countries Well adapted to highly eutrophic conditions (Indicator species of eutrophic near shore conditions) Prohibit dredging (shallow muddy areas) None
Haarder (exotic grey mullet imported from Far East in 1970ís) Expanding stock area; spreading south from Azov Sea, and beginning to produce commercial landings of several thousand tons throughout the region Indicator species for detritus rich conditions near shore. No apparent competition with native mullet, and is consumed by dolphins A coordinated decision will have to be taken as to monitor stock expansion Undetermined. (Suggested a committee be set up by 1998 to monitor exotic species, with an annual budget for critical investigations and meetings of $20,000)
Blue crabs Unexploited, but potentially valuable Well adapted to eutrophic conditions None Undetermined
Sandlance and Silversides Unexploited resources now present at much higher biomasses than formerly Indicators of higher planktonic productivity None Undetermined
