Abstract

The present invention relates to a method fox mixed-raising crab and clam. It is characterized by that in every ma of water surface in which 1000 breeding clams are being bred 5-8 kg of juvenile crabs can be bred. Besides, said invention adopts special-purpose bag for raising breeding clams, every bag can hold 3-4 breeding clams, and regularly adds food and changes fresh water, and regularly spread quicklime powder so as to attain the goal for mixed-raising clams and crabs.

Description

Technical field [0001] The invention relates to a method for mixed cultivation of crabs and pearl-growing mussels. technical background [0002] Both pearls and crabs are "treasures" in freshwater aquaculture. Their market demand is growing steadily and their economic benefits are relatively high. In the previous freshwater aquaculture, there were pure cultivation and polyculture of fish and mussels in the cultivation of pearl-bearing mussels, and there were also pure cultivation and polyculture of fish and crabs in the cultivation of crabs. Due to the fact that crabs eat clam meat, and both are species that require a large amount of calcium, it is difficult to mix them together, and they have not been adopted in production. Contents of the invention [0003] The purpose of the present invention is to provide a method for mixed cultivation of crabs and mussels. [0004] The present invention is realized in the following way: choose the triangular sail mussel with good qu...
