Problems solved by technology

However, there are also many shortcomings in traditional cage culture: the mesh is easy to block and needs to be cleaned frequently, and the workload is heavy; the residual feed and eel excreta will accumulate in the cage, and over time, it will produce an unpleasant smell. It is beneficial to the growth of rice field eels; feeding rice field eels leads to a decline in the meat quality of rice field eels, and at the same time causes certain pollution to the environment. Moreover, the artificial breeding of eels has not been completed yet, and all eel species are wild-caught. How to make full use of the current wild eel species resources, And discovering higher-value downstream derivative products has also become a major challenge for the eel farming industry

Embodiment 1

[0029] After the ponds and net cages were disinfected in April, the net cages were hung in the ponds in May, with an interval of 1.5 meters between each net cage. Water peanuts were cultivated in the net cages to improve the living environment of rice field eels and provide them with rest and shade. Shrimp, crucian carp and silver carp are stocked in ponds; at the end of June, healthy, non-injured and disease-free deep yellow large spotted eel seedlings are selected at a weight of 50-60 grams per piece, and they are stocked at 2-2.5 kg per square meter. Carefully feed the fish and earthworms; enter winter at the end of October, raise the water level to 55 cm, and cover the eel pond with a layer of white transparent plastic film to keep warm, so that the eel can survive the winter smoothly, and no other feeding is required during the period; the following year 4 At the beginning of the month, when the temperature rises, feeding begins, and it will be caught and marketed by the e...

Embodiment 2

[0031] After the ponds and net cages were disinfected in April, the net cages were hung in the ponds in May, with a distance of 1 meter between each net cage, and water peanuts were cultivated in the net cages to improve the living environment of ricefield eels and provide them with rest and shade. Shrimp, crucian carp and silver carp are stocked in ponds; at the end of June, healthy, non-injured and disease-free golden small-spotted eel seedlings with a weight of 55-60 grams are selected, and they are stocked at 2.5-3 kg per square meter. The fly maggots are carefully fed; when winter enters at the end of October, the water level is raised to 60 cm, and a layer of white transparent plastic film is covered on the eel pond to keep it warm, so that the eel can survive the winter smoothly and no other feeding is required during the period; Feeding starts when the temperature rises, and it will be caught and marketed by the end of October. During the period, check the condition of...

Abstract

The invention relates to the technical field of aquaculture, in particular to the field of finless ell breeding. The high-efficient, intensive and ecological finless ell breeding method comprises the following steps that sterilization is conducted on a pond and a net cage; the net cage is hung to cultivate aquatic plants, and crucian and chub are bred in the pond; artificially-cultivated finless ell seedlings are selected and put into the net cage to be bred; live fly maggots or earthworms are thrown into the pond during the breed cultivation process to be used as bait; the finless ell is bred in a two-year period, and grown finless ell is collected to appear on market. The high-efficient, intensive and ecological finless ell breeding method has the advantages of being capable of improving water quality, improving the quality and value of the finless ell, and prompting the bait breeding industry and the downstream derivative products at the same time.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for efficiently, intensively and ecologically cultivating rice field eels. Background technique [0002] Swamp eel, also known as eel, has tender meat, delicious taste, less bone spurs, rich in protein, multi-vitamins and minerals; Swamp eel is also rich in DHA, EPA and other medicinal ingredients, which have the functions of nourishing qi, blood, anti-inflammatory and disinfection. , expelling wind and dehumidification and other effects, it is a delicious food and nourishing health food loved by consumers at home and abroad. At present, it is becoming more and more popular in domestic and foreign markets. The annual demand in the domestic market is nearly 3 million tons. Japan and South Korea need to import 200,000 tons a year. The demand in Hong Kong and Macao is also showing an increasing trend. At present, the main source of supply for the rice field eel market ...
