Technical Field
The invention relates to the field of biological feed, and particularly provides a palaemon carinicauda and swimming crab set health preserving material fermented feed and a preparation method and application thereof.
Background
The swimming crabs and the palaemon carinicauda are rich in nutrition and are important economic aquaculture animals. The cost of separately culturing the swimming crabs and the palaemon carinicauda is higher, so that the swimming crabs and the palaemon carinicauda are cultured in a mode of culturing the swimming crabs and the palaemon carinicauda in a combined mode at present. The complete culture needs to feed the baits of the shrimps and the crabs respectively to provide sufficient nutrition for the shrimps and the crabs respectively. But feeding separately results in increased labor costs. In the feeding process, the icefish is generally used for providing sufficient animal protein for the portunids, and the icefish is easy to breed foreign bacteria and pollute water quality, so that the crayfish and the portunids cannot shell, and the culture benefit is seriously influenced. In addition, most of the nutritional ingredients of the current intercropping baits are macromolecules, and the digestion, absorption and utilization efficiency of animals is low; the existing biological feed is easy to be polluted by mixed bacteria. Therefore, the feed for the mixed culture of the swimming crabs and the palaemon carinicauda, which can optimize the water quality and improve the yield, needs to be developed urgently.
