The native crab of Pontevedra, a smaller species than the king crab, is highly valued for its taste, nutritional content, and economic importance. Found mainly in ponds and rivers, these crabs have various classifications, including the M1 male crab, OS6 female crab, and others, each distinguished by weight, body fat characteristics, and belly shape. They are widely consumed during special occasions and have medicinal properties, such as potential treatments for dengue and cancer. The crab industry contributes significantly to Pontevedra’s economy, though it faces threats from natural disasters. Conservation efforts include careful pond management to ensure sustainable crab farming. Superstitions surround crabs, especially during times of mourning, as consuming seafood is believed to bring bad luck.
