Cultivating mussels needs to pay attention to the following aspects:
1. Breeding methods: At present, mussels are mostly raised by hanging and cage culture. The hanging culture method includes single hanging culture and string culture, and hanging more than two mussels on one line; The number of cages depends on the size of the cage (cage, cage, clip), and it is generally appropriate for each mussel to be able to touch the bottom of the cage.
2 Breeding density: Breeding density should be determined according to the age and size of mussels. Generally speaking, 1200 1500 mu of 1st year old mussels, 800 1000 mu of 2nd year old mu, and 600 mu of 3rd year old and above are appropriate. In the case of polyculture, it is necessary to pay attention to the reasonable matching ratio, and the annual output of fish should be controlled at 500 750 kg mu. Polycultured fish can only be grass carp, bream, carp, shark and other omnivorous fish.
3 Fertilizer and water feeding: Mussels feed mainly on plankton in water, so fertilization and cultivation of water quality are particularly important. After clearing the pond, 300 kg of fermented duck manure was applied in time. Generally, three times a month, the amount of water is determined according to the weather and water color, and the transparency of the pool water is required to reach 30 cm.
4. Water quality management: When raising mussels in closed and still waters without flowing water, it will cause hypoxic death of mussels after high temperature, shallow water and low pressure. Therefore, it is necessary to add water in time, change the water or keep the water fresh and the oxygen content is sufficient, so as to avoid hypoxia of mussels. Low oxygen conditions can affect the growth of mussels.
5. Remove attachments: After a period of breeding of pearl mussels, a large number of attached mud and organisms (such as algae, freshwater sponges, polycondensation insects, etc.) are often attached to hanging net cages, net bags and pearl mussels, affecting the growth of mussels, so they must be cleaned regularly. Rinse every other month from April to October.
6 Light management: Sufficient sunlight exposure can directly produce thermal effects, thereby providing energy for pearl mussels and their bait organisms.
The above information is for reference only, and the specific breeding methods may vary depending on the region, breed and other factors. It is advisable to consult a professional or conduct in-depth research before the actual farming to ensure the success of the farming and get the best economic benefits.
