The latest artificial culture technology of European eel

European eel is a kind of eel that grows in Europe. this kind of eel is a special breed. At present, the artificial culture technology of European eel is not very mature, especially in the breeding technology of European eel. It is still impossible to achieve artificial reproduction, so here the editor will first tell you about the artificial culture technology of European eel!

I. Pond conditions

For breeding European eel, we must first choose a clean water source, and then build a pond. The pond should have good drainage and air permeability, it is best to be close to some large river basins, and the stem of the pond should be two meters high. then the access to the water should be designed with sewers, there are inlets and sewage outlets, all of which need to be repaired, and the filter should be installed at the opening during repair, so as to ensure that the European eel will not escape.

2. Pond preparation

1. Two months before putting the eel fry, we should clean up the weeds and clutter in the pond, check the inlet and outlet, see if there are any damage and loopholes, and thoroughly clean and inspect the pond.

2. After cleaning up the pond, we should use disinfectant or disinfection solution to disinfect the pond. Trichlorfon can be added to the disinfection water, so that the disinfection effect will be better. After disinfection for a week, bleach can be used to disinfect the whole pond again.

III. Stocking

1. First of all, the eel fry should be selected, and the eel fry that grow well should be left for stocking, such as those with normal body color, active and parasite-free, and the stocking density and quantity should be considered in advance. The stocking density should not be too high, otherwise it will cause lack of oxygen in the pond.

2. Keep the water level of the free-range pond below one meter, add about 10 centimeters of water every day, change the water frequently, keep the visibility of the water within 20-30 centimeters, disinfect the pond regularly, and use formalin plus antibiotics for medicine bath.

IV. Feeding and management

The water temperature should be controlled well. Generally, the best water temperature of European eel is between 24 and 28 degrees Celsius. If the temperature is too high, you can reduce the feeding rate, otherwise, the water quality should be transparent and fresh, not too turbid, and the yellowish green water quality is the best. If the discoloration is too serious, the water quality should be rectified, and the number of microorganisms in the water should be observed. If there are too many, it is necessary to control the water quality. To avoid affecting the growth of European eels.

The above is the latest artificial culture technology of European eel, do you understand? Although the European eel needs a little content in the culture technology, it is still relatively stable, and the survival rate is relatively high, which can obtain stable income.
