Ốc đực (stream snail), also known as khe snail, is a famous specialty in Minh Hoa District, Quang Binh Province. This species of snail lives mainly in fresh mountain streams, where the water flows fast and is rich in minerals from limestone mountains. These habitats share common characteristics: clear, cool, mineral-rich water, creating ideal conditions for stream snails to thrive. The shell of the stream snail is small, elongated, brown or gray, allowing them to easily cling tightly to rocks against strong currents.
- Size: The stream snails are small, about 2-3 cm long, with thin but sturdy shells.
- Diet: They feed on algae and microorganisms in the water, which contributes to the natural sweetness of the snail meat.
- Season: Stream snails are present year-round, but the rainy season (around June to October) is when they reproduce the most, are easiest to harvest, and offer the best quality.

Minh Hoa stream snail meat is not only delicious but also rich in protein, calcium, and essential minerals. According to folk tradition, stream snails have cooling properties, helping to clear internal heat and promote good health, especially for those doing hard physical labor or needing an energy boost.
