The solution to the malpractice of fish culture in chicken manure with unbalanced nutrition

fish culture

There are many residual nutrients in chicken manure. Using chicken manure to raise fish not only saves commercial feed, but also improves economic benefits and reduces environmental pollution. But chicken manure fish also has disadvantages: organic matter increased, ammonia nitrogen is too high, serious oxygen consumption, pond bottom quality hypoxia, nutrient imbalance and so on. Therefore, when using chicken manure, the following solutions can be taken:

1. Use during low temperature period

Chicken manure is best arranged in winter and spring as a base fertilizer, high temperature, a small amount of bleaching powder or strong chlorine disinfection of fermented chicken manure;

2. Use with microecological agents

Microecological agents can effectively absorb ammonia nitrogen, transform nitrite, change algae phase, decompose organic matter and release nutrients. Such as: nitrite high open aerator, Bacillus at the same time using granular oxygen, biological substrate, etc.

3. Disabled when the disease occurs

Because a large number of organic matter can cause bacteria to attach and reproduce rapidly, so that pathogenic bacteria spread rapidly, thus increasing the incidence of fish;

4. Combination of organic fertilizer and inorganic fertilizer

Organic fertilizer and inorganic fertilizer combined use can make full use of all kinds of nutrients, make all kinds of nutrition balance, promote plankton growth, achieve algae phase balance, pool water long-term in "fertilizer, live, tender, cool" state.
