The main food of silver carp is zooplankton, and the main food of silver carp is phytoplankton. Fertilizer water is a key link in the process of silver carp cultivation, which can increase the content of plankton in the water body, provide sufficient natural bait for silver carp, provide the nutrients required by silver carp, promote the growth of silver carp and improve yield.
1. Fertilizer and water methods.
1.Fertilizer fertilizer water: We can use fertilizer for fertilizer water. Commonly used fertilizers are chemical fertilizers, organic manure, organic biological fertilizers, etc. Many breeding friends are using: silver carp rapid growth pioneer, containing a variety of amino acids, active peptides, nitrogen, phosphorus and potassium and trace elements, can quickly fertilizer hydroponic algae to cultivate rotifers, fertilizer effect is long-lasting, green and environmentally friendly.
2.Bio-fertilized water: Fertilized water can also be made using microbial agents. Microbial agents can promote the growth of plankton and provide natural forage for silver carp. We commonly use: EM bacteria pioneer, high content and strong activity, can increase the content of beneficial microorganisms in the pond, improve fertilizer utilization, and promote the growth of plankton.
Second, the main points of fertilizer and water.
1.Provide nutrients: Fertilizer water is rich in nutrients such as nitrogen, phosphorus, and potassium, which can provide the nutrients needed for the growth of silver carp.
2.Promote plankton growth: The nutrients in the fertilizer water are conducive to the growth of plankton and provide natural bait for silver carp.
3.Regulate water quality: Fertilizer water helps to regulate water quality and maintain the stability and transparency of the water body.
3. Fertilizer and water management.
1.Timely fertilization: Timely fertilization according to water quality, water temperature and other factors. Generally, fertilization is carried out when the water temperature is suitable and the water quality is good.
2.Appropriate fertilization: Appropriate fertilization according to factors such as the size of the water surface and the growth stage of the silver carp. Avoid deterioration of water quality due to over-fertilization.
3.Uniform fertilization: It is necessary to spread the fertilizer evenly in the breeding pond to avoid excessive local concentration, resulting in deterioration of water quality.
4.Regular monitoring: Regularly monitor water quality indicators, such as ammonia nitrogen, nitrite, etc., to ensure water quality safety.
