The Crustawohl project focuses on welfare to optimize whiteleg shrimp farming in RAS systems. Chronic stress is investigated to discover some reliable markers. Stress experiments based on stocking density, nitrates exposition and exuviae removal will be carried out. Findings will be tested in the project partner’s OCEANLOOP farm, at a larger scale environment. The project implies a wide range of analyses in the field of health observation, histology, physiology, genomics and shrimp behavior. The final goal is to produce the first shrimp welfare index, that farmers might use as a reference to the early recognition of anomalous conditions.
