Corbicula fluminea, also known as Corbicula fluminea, snail, grouper, etc. , widely distributed in lakes and rivers in China, rich in natural resources. They dig holes in the bottom soil and feed on plankton, with fast growth and strong reproductive ability. They are an important small freshwater economic shellfish, which are large and small in China.
breeding method
Meretrix meretrix is most suitable for breeding and growth in medium-sized waters with gentle flow and frequent micro-flow. The water source should be clear, pollution-free and fertile, but it should not be too fertile. Neutral or alkaline water quality is the most suitable, light yellow-green or light green-brown water color is the most suitable, the transparency requires 45 to 90 cm, and plankton is abundant, with a flow rate of 0.2 to 0.6 meters per second.
Swirl is most suitable for Corbicula fluminea culture waters, which can promote the reproduction and growth of plankton and is in a flowing state, which is convenient for Corbicula fluminea to eat. The rapid water flow is not conducive to the growth and reproduction of Corbicula fluminea and the attachment of larvae. If there is no water flow, Corbicula fluminea will have poor feeding, slow growth and low yield. The depth of Corbicula fluminea 1.5 to 3m, and there is soft mud at the bottom of the water, so that Corbicula fluminea can absorb more abundant nutrients.
