1. Change the water method. At present, there are various methods for changing the starting time and changing the water. Most of the larvae in the pool, the breeding pond first add about 1/2 of the water, the larvae into the pool after the first 2 days -3 days, because the water quality is relatively fresh, the amount of feeding and larval metabolites less, add water only daily undrained, gradually Fill the pool and start changing the water. Some also began to change water on the second day after the ear larvae entered the pool. It is also possible to adopt a water-feeding cultivation method, that is, after entering the pool from the ear larvae, water is fed from one end of the cultivation pond and drained from the other end, but water cannot flow for a few hours after feeding. Drainage usually uses tools such as cages, filter drums, and filter rods.

(1) Change the cage water. The cages are made of 200 mesh or 260 mesh sieves and are mostly square in shape. The height of the cage is preferably 10 cm above the surface of the cultivation pond, and the length is 50 cm - 60 cm. The cage frame can be welded with rigid plastic tubes or steel bars, and the frame size is slightly larger than the cage size. Place the cage on the side of the culture tank, insert the siphon and then drain it outside the tank.

(2) Change the filter drum. The filter drum is made of a plastic tube with a diameter of 20 cm to 25 cm and a length of 25 cm to 30 cm. The sides are sealed with a 200 mesh or 260 mesh sieve. A thin plastic tube with a diameter of 3 cm to 5 cm is inserted in the middle of the tube. After the hose is inserted into the tube, it absorbs water.

2. Change the amount of water. Generally change the water once a day - 2 times, each time the amount of water for the culturing of water for the 1/4 to 1/3, each time the amount of water for the cultivation of water about 1/2. In the specific operation process, the visual water conditions may be appropriately increased or decreased. Due to the long flow time and slow flow rate, the water flow culturing method is not severe when the larvae are attached to the sieving lintel. It can reduce the larvae's mechanical damage. The amount of water flowing in the early days can be controlled at about 100%, and it can be increased to 100%-200 in the later period. %. In addition, if you feed more substitute bait and it is easy to spoil the water quality, you should increase the amount of water exchange.

Sea cucumber promotes growth of specific glycopeptides

Main components

Antimicrobial activity of small peptides, twelve kinds of genetically engineered bacteria, citrus concentrated element, oligofructose (FOS), capillaris, calcium gluconate, trace elements.

Traits

This product is yellowish-brown, fluffy, slightly wet, floury, mellow, water-soluble. The main function

1. Anti-disease, prolongation: Concheamine, protein, vitamins and immune active substances, etc., can activate the immune system of aquatic animals and improve the intestinal digestive system. Improve the utilization of food, enhance immunity and disease resistance, and increase growth rate and survival rate. The breeding period is shortened by 10 days to 15 days while improving quality.

2. Adjust water quality: Purified water 2 days - 3 days, effectively improve water quality, improve the transparency of aquaculture water, control the production of ammonia, nitrogen, nitrite and other harmful gases, adjust the pH value. Increase dissolved oxygen in water to prevent eutrophication of aquaculture water bodies and precipitate suspended solids. Make the water quality "fat, live, tender and cool".

3. Clear pool bottom: Use 3 days to 5 days to reduce ammonia and other harmful substances in the culture water, rapidly decompose and use the residual baits, excrement and organic substances in the water, and activate the water body, increase the natural feed, Maintain micro ecological balance and bactericidal action.

4. Reducing the cost of breeding can balance the beneficial microbial flora in the intestine and significantly reduce empty stomach. Effectively prevent enterocolitis and reduce the amount of drugs used.

5. Fertilizer: Control the algae phase and suppress the growth of cyanobacteria. The directional cultivation of diatoms acts as a fertilizer.

6. Effectively prevent stress, reduce floating head and sudden death in hot and hot weather. Does not consume water oxygen, hot, heavy rain, continuous rainy weather does not affect its effectiveness.

Scope of application

Suitable for a variety of special aquatic breeding use. Dosage

Mixing: Add 5%-10% of this product. Long-term health care can be used at 3%-5%, with better results. Water purification: 5 kg of this product for every 3 mu - 5 mu (2 days - 5 days effective, 10 days/time - 15 days/time)
