Aquaculture and aquatic plant intercropping, that is, the use of aquatic plants such as alfalfa, lotus root, rushes, cress, etc., as well as abundant aquatic animals such as zoobenthos, plankton, and soil decomposing microorganisms, etc. The aquaculture industry, with its unique combination of ecological breeding and new production methods, has received the benefits of bait-saving, water-saving, and land-saving. It has the advantages of less investment, convenient management, and high economic efficiency. It is of great significance to adjust the industrial structure of rural areas, develop the rural economy, and increase the income of farmers. The breeding methods are described below.
1. Dianchi Lake can be used as a stocking pond after it has been transformed into a pond, ditches, and paddy fields that have been planted in rural areas. The artificially constructed rearing pond is 1.8 meters high, has a water depth of 0.8-1 meter and is 3 meters wide. The length should be determined according to the amount of feeding. In general, the species of aquatic plants such as white peony and lotus root occupies one-third of the total area and is used as a habitat for otters. It is also possible to artificially place irregular stones or branches at the bottom of the pool and inhabit the water supply. At the same level as the water, one is provided for entry and the other is for the drainage outlet, and it is blocked with a mesh cloth to escape with water. Newly-opened ponds also need to put in some animal manure to cultivate plankton, regulate water quality and increase the bottom of humus. Generally, 50,000 seedlings (cubs) can be released per acre of water. 60,000 species, about 20 kilograms.
Second, daily management Feed feed. To feed pigs, cattle, sheep and other animal blood clots, snails, river clams, etc., to adhere to the "four definite" feeding method, every 3 to 5 meters place a piece of blood clots, etc. (can be set food Taiwan used thin net bags hanging in the water), after the smell of water smelling leeches will quickly gather, after the absorption of self-dissipation, but should pay attention to timely removal of debris, so as not to pollute the water quality. 2. Water quality management. Strictly prevent pesticides and chemicals from contaminating water sources, and do not use water sources that are too alkaline. The well water with low water temperature must go through a certain process and can only be used after the temperature rises. In the summer heat season, in order to avoid the poor growth of blisters caused by the high temperature of the pool water, shade plants should be planted in the pool, and the water should be changed frequently to keep the water temperature below 30°C. Change the water every 7-10 days, and change the water every 3-5 days in the hot summer season. 3. Prevent disease. The leeches have strong vitality, crude growth and longevity, no disease, easy management, as long as the feed is fresh and palatable, the water quality is fat, not rot, live and not light, ensuring that the pool water is clean. 4. Keep catching species. The otters that were stocked in early spring have been grown from September to October and can be processed and sold. In order to guarantee the source of the cultivated leeches in the coming year, individual species that grow and grow robustly can be kept for a year and grow. 25-0.5 kg election stay. 5. Aquatic plant management can be operated with reference to agricultural technical requirements.
