The shrimps grow in field swampland, to ensure the fresh flavour, we choose good quality shrimps alive to deepfreeze and then freeze dried them. We do that because the color and flavour of shrimp should change under the condition the shrimps die and some fishes don't like the dead shrimps. Under the freeze dried treatment, the water in body is lost in the moment and the shrimps keep in all kinds of nutrition and natural astacin contents. The shrimp contain some kinds of nutrition which can accelerate the growth of fishes ,for example, crude protein, crude fibre, crude fat and etc. The most important function of above nutrition is the ability to rapidly enhance the color of tropical fishes for four times astacin contents compared with the others. There is a significant difference between the fish fed with the shrimp and no. After to be fed with the shrimp, the color of tropical fish is obvious fresh, especially on red. No any additives nutrition which can't pollute the water and is easy to be absorbed by fishes. The main kinds of fishes that are fitted to feed with shrimp: Arowanas, flower horn,cichlids , dimsum .
