Cage fish characteristics and high yield principle

Cage fish, also known as "cage fish", is a synthetic fiber mesh or metal mesh for the material, assembled into a certain shape and size of the box, set in suitable for the fish in the water used to fish. Cage aquaculture is the world aquaculture industry to intensive production development of a new technology, with high yield, low cost, small investment, easy to manage, saving water and land economically, the effective development of rivers and lakes large surface water fishery waiting point.

The company is located in:
Cage culture of high-yielding principle: First, the fish kept in the cage, reduced activity, lower respiratory rate, slow metabolism, energy consumption is reduced, is conducive to the conversion and accumulation of nutrients; Second, the water inside and outside the box can be freely exchanged , Get enough oxygen and natural food, fish excrement with the flow out of the box, fresh water, so that fish have a superior living environment; third is to avoid the waters of predatory fish and aquatic animals attack, improve survival Rate; Fourth, according to different fish, preparation of different feed, favorable intensive high-yield and fish disease prevention and control; Fifth, cages facilitate management, easy to start adult fish, capture the rate of return.
