Method for cultivating mussel seedling of hyriopsis cumingii

Abstract

The invention relates to a method for cultivating Hyriopsiscumingii seed, characterized in that adding soil water and fine soil 12 times in the cultivating period, and increasing the their consumption in the growth, and the invention has two steps that 1, from the fifth day to the 20th day, after seed releases, adding soil water in each three days for six times, while the fine soil consumption is 0.025-0.35kg in unit square meter cultivate pool, to prepare soil water when the ratio between soil and water is 1:4, that adding soil water for 0.125-1.75kg, 2, from 23rd to 38th days after seed releases, adding fine soil in each 3 days for six times, while each square meter cultivate pool has 0.5-1.5kg fine soil. The invention can build good condition for Hyriopsiscumingii seed, with abundant oxygen and nutrient, thereby improving survival rate, growth speed and uniform size.

Description

Technical field [0001] The invention relates to a cultivation method for improving the survival rate and growth speed of the triangular sail clam seedlings. technical background [0002] Pearls are important medicinal materials and precious decorations. As early as 2000 BC, there were records of taking spiders from mussels as tributes. Now, in Jiangsu and Zhejiang, cultured pearls are used as an effective way for farmers to become rich and well-off. It not only meets the needs of the domestic market, but also sells to many countries and regions in the world. At present, among the freshwater pearl species, the pearl of the triangular sail clam is the best in quality, and the breeding efficiency is also the highest. Therefore, in production, the three-sided sail mussel is used as a cultured species, and an important factor affecting the cultivation of the three-sided sail mussel is the mussel seedling breeding technology. Mussel seedlings refer to juvenile mussels that have ...

Problems solved by technology

The method for cultivating clam seedlings by laying fine sand at the bottom of the cultivation pond can easily cause the death of clam seedlings due to hypoxia, and it takes a lot of work and is difficult, so it is seldom adopted by people; There is no soil at the bottom of the pool, and the mussels have no place to stand and are always in an unstable state, which is easy to cause mussels to accumulate or drift with the water. Therefore, it is difficult to control in production.
