How are European eels artificially farmed? A detailed guide to the latest technology

The European eel is a species of eel that lives in Europe. This eel is a rather special variety. At present, the artificial farming technology for European eels is not very mature, especially in the breeding technology for European eels, which is still insufficient, and artificial breeding still cannot be achieved. So here the editor will first explain the artificial farming technology for European eels!

I. Pond conditions

To farm European eels, we first need to choose a clean water source and then build the pond. The pond should have good drainage and permeability, and it is best to be near some large river basins. The pond ridge should be two meters high, and the water inlet channel should be designed as a covered drain, with a water inlet and a sewage outlet, both of which need to be built properly. When building them, filter nets should be installed at the openings so that the European eels can be guaranteed not to escape.

II. Pond preparation

1. Two months before putting in the eel fry, we should first clean up the weeds, debris and all sorts of miscellaneous things in the pond, check the water inlet and outlet to see whether there is any damage or leakage, and thoroughly clean and inspect the pond.

2. After cleaning the pond, we should use disinfectant water or a disinfectant solution to disinfect the pond. Trichlorfon can be added to the disinfectant water, which will make the disinfection effect better. One week after disinfection, bleaching powder can be used to carry out another comprehensive disinfection of the whole pond.

III. Stocking

1. First, the eel fry should be selected, and the eel fry with good growth should be kept for stocking. Those with normal body color, lively movement and no parasites are the standard. Before stocking, consider in advance the stocking density and the number to be stocked. The stocking density should not be too high, otherwise it will cause oxygen deficiency in the pond.

2. The water level of the stocking pond should be kept below one meter, with about ten cm of water added each day. Change the water frequently, keep the water visibility within 20-30 cm, and disinfect the pond regularly. Formalin plus antibiotics can be used for medicated bathing.

IV. Feeding management

The water temperature for rearing should be well controlled. Generally, the optimal water temperature for European eels is between 24-28 degrees. If the temperature is too high, the feeding rate can be reduced, and if it is too low, then do the opposite. The water quality should be kept relatively transparent and fresh, not too turbid. Yellow-green water quality is the best. If the color changes too seriously, then the water quality should be rectified. In addition, the number of microorganisms in the water should also be observed. If there are too many, they should be controlled to avoid affecting the growth of European eels.

The above is the latest artificial farming technology for European eels. Did everyone understand it? Although European eels require a bit of skill in farming technology, they are still relatively stable to raise, and the survival rate is also relatively high, so stable returns can be obtained.
