European crayfish in recirculating systems
In this project, we will examine at what temperature, light regime, water quality, density and environment adult European lobsters should be reared to grow optimally and what nutrition is required to do so.
The crisis is prompting Flemish agricultural circles to creatively explore opportunities for diversification. A (global) trend of increasing consumption of farmed fish and shellfish appears to coincide with a rising interest in quality food. However, the latter is not interpreted in purely technical terms (e.g., "slow food" movement), but often incorporates notions of authenticity, sustainability, local production, etc. Within certain niches, there seems to be an opportunity here for in-house production of European crayfish, known for its exceptional taste.
In open farming systems, European crayfish is very vulnerable to a fungus spread by exotic crayfish (the ones usually eaten), therefore we choose to work in closed farming systems (Recirculation Aquaculture System, RAS). This also offers environmental advantages because water use and waste products can be well controlled. We currently see this culture as a possible additional industry on existing farms.
The objective of this research project is twofold:
-
To elaborate a technical "breeding sheet" for European crayfish;
-
To assess the profitability and market potential of such breeding in Flanders/Belgium.
In this project, we will examine at what temperature, light regime, water quality, density and environment adult European lobsters must be reared to grow optimally and what nutrition is required to do so.
Apart from successful breeding, marketing is also extremely important. Therefore, we examine the potential market price for crayfish (for grower and consumer) and its stability. We also analyze the market potential (market size, distribution possibilities, etc.) because these largely determine the commercial viability of the product.
From bringing together the technical necessities and market opportunities, we will be able to conclude whether and under what conditions the commercial farming of European crayfish in Flanders is a possibility. This will require the execution of a financial-economic analysis.
