Comb jelly plague reached Caspian Sea The comb jelly Mnemiopsis leidyi is seriously threatening the Caspian
Sea ecosystem. It first invaded the Black Sea in the late 1980's causing
the fish stock to crash from more than 700,000 to less than 100,000 tons
per annum (see Coastal
Guide News No. 19 ). The first certified record of Mnemiopsis in the
Caspian Sea was made in the autumn of 1999 along the Kazakh coast, most
likely transported from the Black Sea via the Volga by ship ballast water.
An international team of has announced that the Caspian Sea is already
teeming with Mnemiopsis. As the fist-sized jellyfish feeds primarily on
zooplankton, it could very well cause the main Caspian fish species called
Kilka (a collective name for several sardine-like pelagic fish) that also
feed on zooplankton to collapse. This in turn would mean an end to many
fisheries around the Caspian Sea. Moreover, Kilka is the main food of
the Caspian seal, which also could face a large population decrease. Scientists
recommend the introduction of a jellyfish species that feeds on Menmiopsis
to solve the problem.
Climate change report stresses importance of ICZM In order to better cope with the consequences of the ongoing global climate
change, European policies need to be reviewed, says a recently released
report "Assessment of Potential Effects and Adaptations for Climate Change
in Europe" (ACACIA), commissioned by the European Commission. Coastal
zones will be substantially and progressively altered by climate change,
actual impacts however, will depend on the magnitude of climate change
and the human adaptation to that change. Losses and changes to coastal
ecosystems are one problem where adaptation measures appear more limited,
particularly in the most threatened areas. Moreover, there is often a
conflict between sustaining socio-economic activity and the ecological
functioning of the coastal zone in Europe under rising sea levels. The
local, national and EU-wide efforts to promote integrated coastal zone
management (ICZM) need to be encouraged to strengthen the institutional
basis for proactive measures, concludes the report. Nearly all European
marine fisheries are either fully or over-exploited, leaving no safety
net for possible climate change effects and threatening most European
fisheries with collapse. In the current policy context, any decrease in
productivity or changes in species distribution are likely to increase
conflicts between aquatic resource users. Policy research is urgently
needed to reconcile market forces and environmental sustainability and
foster adaptive management plans. It is also no longer possible to assume
that the future hydrological resource base will be similar to that of
the present. Water managers need to develop methodological procedures
for adopting a scenario-based approach to strategy or scheme assessment,
and develop adaptive techniques that allow incremental adjustments over
time. The International Council for the Exploration of the Sea (ICES) has finalised
its annual advice to the EU fisheries ministers and concluded that for
several species the situation is alarming. The North Sea cod spawning
biomass is outside safe biological limits, and continued fishing at current
rates will lead to stock collapse. The contents of a draft management and conservation strategy for Black
Sea salmon was endorsed recently by the participants of an international
scientific workshop in Batumi, Georgia. The workshop also initiated he
establishment of a Black Sea Salmon Forum to promote the strategy, to
co-ordinate research and monitoring programmes, and to facilitate sound
fisheries management. The Marine Ecology and Fisheries Research Institute
in Batumi, Georgia, that hosted the workshop and is involved in a programme
to develop a management strategy for Black Sea salmon funded by the European
Union’s Tacis programme, volunteered to act as a coordinating body for
the forum. The Black Sea salmon is a sub-species of the European trout,
Salmo trutta labrax, and is restricted in its distribution to the Black
Sea and rivers flowing into it. It has become extinct in many rivers and
the remaining known breeding populations in Georgia, Turkey and Russia
are under considerable threat from environmental degradation but especially
excessive levels of exploitation. The above mentioned strategy document
recognizes that each river probably has its own genetically distinct stock.
The strategy therefore recommends management plans for each catchment
area. It also stresses the need for co-operation and communication between
all interested parties. On November 2, at the trilateral International Waddensea Conference,
eight Dutch and German nature conservation organizations presented a restoration
plan for the estuary of the river Ems. This is one of the rare examples
of tidal rivers in western Europe, located at the border of the Netherlands
and Germany. Together with the Dollard it forms a tidal nature area. The
area is threatened by plans to build a flood-control dam (see Coastal
Guide News No. 7 ) and frequent dredging operations to make it accessible
for big cruise ships built at a shipyard upstream. The dam is against
international conventions signed by the Dutch, German and Danish governments.
The Living Ems plan intends to foster a more integrated coastal zone management
approach in this region and to stop the dam project.
“Sustainable” EU support to developing countries The European Parliament and the Council have adopted a new regulation
on supporting developing countries in their efforts to integrate the environmental
dimension into their development process. The Community shall provide
financial assistance and appropriate expertise aimed at drawing up and
promoting the implementation of policies, strategies, tools and technologies
for the pursuit of sustainable development. Coastal zone, estuary and
wetland management is included to the list of activities to be carried
out under this new regulation. The European Commission has approved a Communication on European development
co-operation policy in fisheries and aquaculture. It underlines the fact
that fisheries is an essential sector for many societies in developing
countries. Poor communities depending on fishing are increasingly faced
with the risk of depleted aquatic resources. If the necessary measures
are not taken, the economic, social and ecological situation of some the
least developed countries could deteriorate further. The right to fish
involves the obligation to fish responsibly, involving actions at the
level of European co-operation policy, of other European policies which
have an impact on the development of fisheries in the developing countries,
and at the level of the EU Member States. The Communication also makes
a contribution to preparations for the review of the common fisheries
policy, which will be carried out in 2002.
