Features:

1.Improve the water quality and increase the fertilizer in water

In aquaculture it can obviously improve the water quality in the reservoir, pond , increase the fertilizer nutrients in the water, multiply beneficial microbes, increase the source of dissolved oxygen, guarantee the nutrition and dissolved oxygen requirement by the aquatic animal in water, aquaculture diseases prevention for the gas bubble disease, Tail focal disease, rotten gill disease etc, reduce and control the damage due to the fish flipped over on its back,increase production 10-30%.

2.Reduce the use of the chemical fertilizers

The beneficial bacteria in this product could dissolved oxygen, nitrogen fixation, phosphate-solubilizing, potassium-solubilizing, decomposition of organic matter, mineral substance, Chemical salt, deposit sediment, thus this product could reduce or replaced the use of the Aquatic nitrogen fertilizeri and Aquatic phosphorus fertilizer, thus reduce production cost and the chemical pollution, so it was the first choose for aquaculture fertilizer.

3. Prevention and control the happen of Aquaculture disease

The plenty of beneficial microbial in this product could Effectively control the survival and transmission of all kinds of aquatic pathogenic bacteria, to prevent the disease developing.

It was better than the chemical drugs even more it have no pollution and no toxic.

It have obvious prevent and cure effect for the cross infection of bacteria and viruses disease such as the : fish disease, rotten-skin disease, tail-rot disease, saprolegniasis(also called dermatomycosis, white hair disease), Leprnorthsis.

4.Reduce the harm of parasites

This product have better prevention function of the Reproduction of aquatic insects,such as the Costia Live on the fish, flagellate, Chilodonella cyprinid, Small claw worm, Fish lice, dactylogyrus, Gyrodactylus and Lernaea. It also could alleviate the harmful of Costiasis, ichthyophthiriasis, argulus, reduce the rate of death, improve the quantity of aquaculture production.

5.Improve the utilization rate of aquatic animal feed

The beneficial microbes of this product can promote fish digestive gland secretion, Enhanced the appetite of the aquatic animal, eliminate the antagonism function between nutrient, shorten the Feeding time, increasing feed efficiency.

6.Reduce the dosage of feed

This products contains plenty of protein, amino acid,vitamin, it could replace the feed by 10%-20%.

Use methods:

Used in the Reservoir, pond.

For example the water is 2 meters depth for each HA

1.Use this product alone: 30-45KG per time ,3-4 times each month

2.Use this product with the chemical fertilizer:15-30 KG this product+UREA15-45 KG +superphosphate 45-90 KG per time,3-4 times per month.

In the same time reduce the invest of drugs by 20%-50%.

Notes:

1.This product could use with the chemical fertilizer together,

2.Can not use or stock with the fungicide and the alkaline matter
