Commercial production of mussels has a number of challenges whose solution requires a focused research and development effort. Requirements for nature conservation, including implementation of Natura 2000 and Water Framework Directives, restrict exploitation of wild populations of mussels in many areas. A reduction of concentrations of nutrients in the inner Danish fjords can over time be expected to reduce fishing of mussels further. A solution to this problem is the development of new area-intensive forms of production, as the cultivation of mussels on longlines or in bottom cultures. Another challenge in the production of mussels is a growing competition from Chilean producers of cooked or frozen mussels. A development strategy for Danish mussel production is an increased focus on the production of high quality mussels for fresh consumption, where competition is restricted to European producers. Important parameters of competition in this market are quality and supply continuity. The overall aim is to optimize a 500 tons production concept, where mussel seed is farmed in the water column on Smart Farm Systems, harvested and laid in bottom culture for future harvesting as mussels for fresh consumption.

The project milestones are:
- To document the optimal harvesting and relay size.
- Study if sizing before relaying in bottom cultures can improve the end-product.
- Documenting the growth and survival of relayed mussel seed as a function of layout density.
- Comparison of growth rates of mussels on longlines and in bottom cultures.
- Establish 3-D model of biological production in the area near the east coast of Jutland, and implement a survey of the best areas for culture bank cultivation.
- Analyze the management and operation of economic prospects for production concept.

The project is coordinated by DTU Aqua.
