Mussels (also known as purple mussels). Classified in the classification of molluscs door, valve gills, different column heads, lobe family. Distributed in China's Yellow Sea and Bohai Sea. It is now moving south to our province and even coastal Fujian. Meat is delicious and delicious, with the name of milk in the sea. The dry product processed is called mussels. First, living habits Mussels have a strong ability to adapt to the environment, and can live in a water temperature of -2-28°C. The suitable growth range is 13-26°C. The secretion of foot filaments is most vigorous at 10°C. Mussels are quite resistant to dry dew and sun exposure. In the summer, when the temperature is 27-30°C, one day in the sun, the sky can be dried up for two days. In winter, when the temperature is -5°C, it can be cloudy for up to 5 days. Mussels also have a wide salt range and can survive in seawater with a salinity of 6 ‰ or more. The more appropriate range is between 17.6-24.2 inches. Mussels also have strong resistance to harmful environments such as red tides and sewage. In some wharves and wharfs with heavy impact on sewage, harbors and other creatures are almost impossible to survive, but mussels can still live. In the Yellow Sea and the Bohai Sea, there are even piped incidents due to the proliferation of mussels. There are two distinct stages in the life of mussels. First, from the time that the fertilized egg develops to the larvae, until the metamorphosis is attached, it is through the cilia and flagella on the swimming organ “face plate†that they swim in the water; Metamorphosis attached to the life of the foot attachment. Mussels are passive filter foods, mainly planktonic diatoms, dinoflagellates, and organic debris.
Mussels have two breeding peaks during the year, and they are in May-June and October-November respectively in the south of Zhejiang. In addition, there is a phenomenon of hermaphroditism and sexual changes in the life of mussels. Second, the development of technology Although the mussel artificial breeding technology has been mastered, but due to the low price of northern mussel seedlings, the current farming seedlings are mainly from the north to adopt natural seedlings to solve. 1. Seedling and seedling transport: Seedlings and seedlings are generally transported at low temperature for dry transport. Low temperature control at 5 °C, the effect is very good. 2. Selection of aquaculture sea areas: The sea areas where mussels are cultured should be selected in areas where the storm is not large, the flow is slow, the translucency is large, and the monocellular algae feed is rich in organisms. At present, mixed use of mussels such as mussels and seaweed or hijiki is effective in some places. 3, Bao Miao: The mussels from the seedlings with the seedlings evenly attached to the cultivation of the seedlings on the rope to be raised into a product for sale. The specific steps are as follows: The mussel seedlings are plucked down from the seedling appendage, and after the binning according to the size and size, a screen mesh is laid on the semi-simple bamboo tube or the semi-tubular shape with a concave shape, and the mussels seedlings are evenly distributed. Spread it, put it on the farmer's rope and tightly sew and hang it. After about a week of mussel sprouts, new foot filaments can be secreted. At this time, removing the screen mesh can be cultured. Third, the harvest: harvest season of mussels is consistent with sexual maturity, that is, when the mussel glands mature the most plump, then you can harvest fresh or steamed cooked shell dry products - mussels.
