Resumo: | The marine farming sector in France is often assimilated, in major speeches, into new aquafarming (fish or crustaceans raised at sea), the production of which remains anecdotal. In practise, oyster and mussel breeds (traditional aquafarming) represent a business sector with an economic weight equivalent to that of maritime fishing.  Major speeches, public sector, corporate and scientific, on new aquafarming have created an "aquafarming paradigm", perpetuated in the form of a system of ideological representations borrowed from other sectors (especially the agricultural sector). Disregarding the efficiency, complexity and determinism of the various aquaculture evaluation systems, this paradigm relies on an evolutionary model that analysis of recent history cannot confirm.  The different results show that the brakes on growth are located at the corporate level, central vector of development of the sector. They are linked to the nature and level of investment on the one hand, and on the other, to the assessment of risks and uncertainties linked to the dependence of production with respect to the environment and the imperfections of aquafarming products markets.  A theoretical model of corporate decision support using linear programming is presented, with a dual objective:  - obtain a general behaviour model of the aquafarming firm independent of its production, taking into account the factors of risk and uncertainty; - allow later use of this model to provide investors, land-use organisations and research with a tool that has multiple functions: sensitivity of the results to modifications of certain factors controlled or not by the company, economic feasibility in an uncertain world, simulation of the optimal evolution of companies in the longer or not quite so long term.
