potential ecological and environmental benefits of mussel farming to
improve coastal water quality have been scientifically known for
recently has mussel farming been suggested as an operational tool
for society to recycle nutrients from coastal waters back to land.
farming can from an environmental point of view be regarded as a
similar activity as open landscape feeding on land.
mussels harvest nutrients through their food intake of natural
phytoplankton from the water. The excess nutrients in coastal waters
can thus be recycled through the harvest of mussel biomass.
biomass can in turn be used for production of mussel meal to be used
in organic feeds or for biogas production and as fertilizer. The
result is clearer water.
of mussels is always done in extensive conditions. The young mussels are
collected from the sea and can be cultured using a number of different
culture - which uses a series of wooden poles as supports, onto
which the mussels are transplanted for on-growing
Suspended rope culture - where ropes, covered with mussel seeds kept
in place by nylon nets, are suspended either from rafts, wooden
frames or from Iong lines of floating plastic buoys.
culture - which depends on the harvesting of young mussels and
spreading them out on specially prepared protected growing plots.
substantial portion of the EC production is grown on suspended ropes, a
technique which can be extended further offshore and which, although
quite sensitive to plankton blooms, is the only one which could further
increase production, since both the ‘bouchot' and the bottom culture
techniques are faced with growing coastal pollution, bird predation and
land use constraints.
is considerable potential for expanding production of the mussels
from the current 30-40 tonnes per year.
before the farms were established in May 2005, up till September
2006, the Mussel Project measured the changes in dissolved
nutrients and oxygen fluxes in the benthic community at three farm
sites with associated control areas.
culture in Europe produces about 50% of the annual worldwide
harvest. The history of mussel culture in some European countries is
aquaculture in Italy started more than 2,000 years ago . The history
of mussel culture in France and the Netherlands is almost 700 years
total production volume of mussels was 37,315 tonnes.
