Have you ever used biological fish fertilizer in the fish pond for raising four large fish?

In fact, in pond fish farming, the application of biological fish fertilizer in Hubei, Anhui, Jiangxi, Guangdong, Jiangsu has long been accepted by fishermen, mainly in the water body of a large number of feeding, the main water surface of the silver carp also with a large number of chicken manure, pig manure and other organic fertilizer fertilizer water, so that the water ammonia nitrogen, nitrite, hydrogen sulfide toxic and harmful substances are produced in large quantities, while the bacterial diseases of fish breed, fish disease outbreak. By adding a class of probiotics such as enzyme bacteria, biological fish fertilizer can inhibit diseases and decompose harmful substances in the water body, helping the success of breeding and increasing benefits. There is no doubt that the traditional chemical fertilizer fish farming is fast and efficient in fertilizer water, and the long-term large-scale use has caused the outbreak of cyanobacteria and fish diseases has been recognized by most farmers.

Therefore, in the process of aquaculture, it is recommended that organic fertilizer (chicken manure, pig manure, quail manure manure), chemical fertilizer (ammonium carbonate, superphosphate, monoammonium phosphate, urea), enzyme bacteria biological fish fertilizer and other mutual use is good, complementary to each other.

Farmhouse fertilizer must take effect after the process is the same as the fertilizer, mainly fertilizer water, may not be as effective as fertilizer direct decomposition and absorption, but farmhouse fertilizer decomposition and absorption effect is more durable.

It is necessary to pay attention to the dosage of over-fertilized water, which has a high microbial content, although it provides a considerable amount of bait, but the oxygen ion consumption of the water body is large, and it is easy to flood the pond.

Yes, plant straw, food factory waste will do.

Hello dear, in order to make the four big fish in the pond (grass carp, carp, bighead carp and mandarin fish) grow fast, you first need to reasonably equip the appropriate feed. Here are some common feed choices and feeding tips for the Mu calendar: Regret Resistance 1

Protein-rich feed: Domestic fish need a lot of protein to grow, so choose a feed with a high protein content. Fishmeal, soybean meal, offal, etc. are usually chosen as the main ingredients.

2.Feed with the right fat content: The right amount of fat is helpful for the growth and development of domestic fish, but too high fat content can lead to obesity in domestic fish.

Therefore, choosing a feed with appropriate fat content, such as fish oil, soybean oil, etc., can balance the nutrient supply. 3.Vitamin & Mineral Supplements:

Domestic fish need the right vitamins and minerals to grow. Depending on the specific vitamin and mineral composition required by the fish, a feed rich in these nutrients can be selected. 4.

Use of compound feed: According to the growth stage and needs of domestic fish, compound feed can be selected. For example, in the juvenile stage of domestic fish, you can choose to pre-add a powdered feed with fine particles to facilitate the consumption of small fish.

5.Regular feeding and appropriate control: The growth of domestic fish needs to be fed regularly, and attention should be paid to the appropriate amount of feed to control.

OK. Crab breeding pond fertilization should be determined according to the water fat and thin situation, the water is generally thin to urea-based, about 5-10 catties per mu, add part of the phosphate fertilizer, about 2 catties per mu. The water fertility is moderate, and the top dressing is generally based on phosphate fertilizer, generally 1-2 catties per mu.

In hot weather, urea or ammonium carbonate is not recommended.

1. Advantages: nutrients are released quickly in the water body, and can reach a very high concentration in a short time, and the fertilizer and water speed is fast.

2. Disadvantages: First, the concentration of nutrients in a short period of time is too high, which can easily lead to excessive algae blooming in the water body and dense water. Second, if the nutrients cannot be quickly absorbed by algae, it is easy to cause the increase of ammonia nitrogen and nitrite in the water.

Third, the nutrient composition is single, and the fertilizer effect lasts for a short time. Fourth, improper fertilization can easily cause the proliferation of cyanobacteria and eugleniflagellates.

In general, it is caused by parasites, such as compound trematodia, silver iodine bubble worm, etc., because compound fluke causes the white silver carp to warp its tail, also known as cataract. This disease, mostly freshwater fish, silver carp, bighead carp, grass carp, etc., serious disease will lead to a large number of seed death, called acute infection, sick fish in the water surface to do jumping swimming, struggling; Sometimes the head is down and the tail is up, or the sick fish goes up and down, and swims rapidly on the surface of the water, and the more obvious symptom is head congestion. Slow infection is that the number of insects that invade the fish body is small, and the diseased fish does not die, and the eyeball will appear lens opacity, blindness, and lens shedding.

Prevention and control measures: pay attention to the snail extermination of the aquaculture water body, splash the whole pool with EM bacteria after the onset of the disease, and use avermectin and other insect extermination.
