Examples of Silver Carp and Bighead Carp Culture in Cage

It is reasonable and correct to put @ # @ 233 children in the cage, which should be determined according to the specific conditions. Generally speaking, more can be put in running water, in cages with high dissolved oxygen in water. The water body is stable, where the wind and waves are small, the places with less oxygen in the water can be put less. In other words, the oxygen in the cage can make each fish have great satisfaction, which is the limit of stocking capacity. If the oxygen can not meet the needs of fish, it means that the stocking is overstocked. Silver carp and bighead carp can be raised without bait in the place of fat and water (transparency is 25cm to 30cm).

In general, the stocking amount can be determined according to the following data: silver carp, 2 bighead carp and 3 bighead carp (2 ∶ 3) with a body length of 4 cm per square meter are reared for 45 and 38 days respectively, and can grow to 13.3cm long. The length of silver carp, 3 bighead carp, 3 bighead carp and bighead carp was 4 cm per square meter, and 1 (3 ∶ 1) 300 silver carp and bighead carp were reared for 54 days and 57 days respectively. The length of silver carp, 4 bighead carp, bighead carp, 4 bi The length of silver carp, 5 bighead carp, bighead carp, 5 bighead carp, 5 bighead carp, silver carp, bighead carp, 5 bighead carp, bighead carp, 5 bighe

The above reference data showed that when the stocking ratio of ① silver carp to bighead carp was 3 ∶ 1, the growth rate of bighead carp was similar, and that of bighead carp was fast at 5 ∶ 1. The growth rate of ② with 250tails per square meter was twice as fast as that with 500tails per square meter. Breeders can determine the stocking amount according to the size of fish species, the goal of cultivation, the difference of dissolved oxygen in water and the difference of bait. The reference stocking quantity is 200 tons per square meter, and small cages should be used in cages.

Site selection: where the water body is rich in plankton, the amount of plankton is 18.4 mg / L (biomass per liter). The transparency of this biomass water body is often 120 cm, which is not fat water in conventional terms. If you put the cage, it should be placed at intervals between the bait box and the non-bait box, not all without the bait box. When placed, do not hinder each other. If the transparency of the water quality is about 40 cm, the non-baiting cage can be placed completely, but the box distance must be maintained. Draught within 2 meters, should maintain a smooth flow rate, there should be wind and waves, sufficient dissolved oxygen, in order to grow good fish. Plankton should be rich, silver carp and bighead carp should be comfortable after eating. The running water is smooth and the dissolved oxygen is sufficient to keep the distance from each other.
