longline device, the enterprise budget for a four-year life cycle was calculated.
Additionally, a new vessel as well as the possibility of using existing capacities of
the mussel farmer community in Lower Saxony will be taken into consideration.
This led to four different scenarios. First, a basic scenario for the farming of
consumption mussels with a new appropriate vessel as well as a new land facility
was assumed. In a further scenario, the above-mentioned existing capacities of
mussel farmers were addressed. The economic analysis was organized as follows:
(1) basic parameters for farm size, culture technology and biomass gain are
described (Table 11.6); (2) time schedule of the farm set-up and harvest operations
were presented; (3) basic data on costs and investment were specified; and (4) finally a sensitivity analysis was outlined.

(bird’s eye view). Four of these six designated plots were calculated according to our mussel
cultivation projections (numbers in brackets). b Presents a design of a single mussel plot within a
