What role does silver carp play in polyculture ponds?

Silver carp plays a role in regulating water quality in ponds. They can use algae and organic matter in ponds to control algae and purify water quality.

How to improve the fertilizer and water effect during silver carp breeding?

1. The complex fertilizer and water market

Looking at the fertilizer products on the market, it is dazzling, but the fertilizer effects are uneven. The majority of users generally only look at the packaging, compare prices, and listen to what people say, which often confuses people's eyes. It is difficult for everyone to distinguish the true from the false about "fertilizer champion", "king of fertilizer", "biological fertilizer", etc. Most people think that "dense green water" and "emerald green water" are good water. This kind of water quality is mainly composed of green algae. However, few people pay attention to the phenomenon that this kind of water quality has a short fertilizer effect time and is easy to overturn algae. Today I want to introduce to you a kind of "yellow-green water", which mainly cultivates ecological balance fertilizers mainly composed of green algae and diatoms. Its fertilizer effect lasts long, the growth of silver carp is obvious, and it is not easy to overturn algae. It can truly be called the champion of fertilizer-algae source element.

2. Continuous tracking process of the effect of "Algae-Depleting Agent"

After fertilizing the water, the water color of the pond is "rich", "lively", "tender" and "refreshing" in the morning, noon and evening. According to the user's fertilizer application time, use Algae Source once every 10 days, and the water fertility can be sustained! The fertility time of Algae Source is amazing!

3. Weigh it and see, Algae Source is the most cost-effective

1. Comparison of specifications of silver carp fishing nets

The stocking specifications of Haida farmer A (6 heads per pound) and nearby farmer B (7 heads per pound) are almost comparable. Through analysis, it is not difficult to see that the cost of Algae Source is only about 200 yuan higher than other biological fertilizers, but the cost of silver carp per pound is almost 100% lower, which reflects the high cost performance of Algae Source Silver Carp.

2. Comparison between body surface and internal organs

Through surface observation and internal organ dissection, we concluded that: 1. In the ponds fertilized with algae-derived fertilizer, silver carp had good body color, wide body and thick caudal peduncle, while fish in ponds fertilized with other biological fertilizers were thin, had poor physique and were prone to hemorrhage; 2. Another criterion for the good growth of silver carp is to look at the internal organs. The intestines are full of food and there is white fat attached to the mesentery. It can be clearly seen that fish using algae-derived fertilizers are fatter.

4. Summary of the Effects of Algae Source

1. Low temperature: fertilizer and water will take effect quickly in 3 days; high temperature: fertilizer will take effect well in 1 day and fertilizer will be kept for a long time in 10 days;

2. Fresh and tender water for breakfast, lunch and dinner, silver carp will be full at every meal;

3. The algae source is packaged in a small size, with a pack of 10 mu and small physical strength;

4. Weigh it and count it like a spring sock. One pound of long fish is the most cost-effective;

5. There is no algae in the yellow-green water, the water is stable, oxygen is sufficient, and the food intake is vigorous.

The first is to apply chemical fertilizers. This method is the simplest method, but the disadvantage is that the fertilizer effect is short. Chemical fertilizers are generally nitrogen fertilizers, supplemented by phosphorus fertilizers and potassium fertilizers. For one fertilization, about 5 kg of effective nitrogen is required per mu. Calculated based on urea with a nitrogen content of about 40%. Then about 12 kg of urea needs to be applied per mu.

Silver carp and bighead carp are filter-feeding fish that we often see. Although they also eat artificially fed bait under artificial feeding conditions, their growth rate, disease resistance, and fish meat quality are completely different after eating artificial feed or natural bait. To put it simply, after eating natural bait, silver carp not only grows faster, has stronger disease resistance, but also produces better fish meat quality.

Fertilizers used. The best ones are those with high organic matter content, preferably organic fertilizers based on fermented chicken manure, and amino acid fertilizers with succinic acid as the main component. Ponds that use mainly chemical fertilizers provide fish with an ecological environment with high dissolved oxygen, low oxygen consumption, and abundant food.
