Large-scale breeding of two ponds
The so-called large-scale breeding refers to concentrating hundreds of acres, hundreds of acres or even thousands of acres of land in the same place to produce Taiwanese loach. The average unit yield is required to be above /acre, and the seeds are collected It is a one-stop production integrating the cultivation of commercial loaches, production of feed, supply of commercial fish, and centralized sales, providing the market with a large number of sufficient commercial Taiwanese loaches.
Site Selection The site selection for Taiwan loach breeding farm should ensure that the water source is sufficient and reliable as much as possible, the water quality is fresh and pollution-free, the pond has easy access and drainage, can be self-irrigated and self-drained, and the soil quality should be neutral or slightly acidic clay soil. , abundant sunshine, convenient transportation and guaranteed electricity.
Construction of a loach pond. The area of the pond is square meters to square meters. When constructing, the unique habits of Taiwanese loaches such as burrowing in the mud and escaping should be taken into full consideration. The surrounding areas of the pond must be higher than the water surface. Cement boards, bricks, hard plastic boards or plastic boards can be used. It is built by compacting three-piece soil. You can also use screen cloth to fence around the pond. The lower end of the screen cloth is buried in the hard soil. The upper end of the screen cloth is higher than the water surface. The pond is deep. The bottom silt is thick. The water depth is kept at the pond water inlet above the water surface. , the drainage outlet is set at the normal water level of the pond, the drainage outlet is set at the bottom of the fish slide at the bottom of the pond, and the water inlet and drainage outlet are wrapped with dense mesh to prevent Taiwanese loach from escaping. In order to facilitate fishing, the pond should be equipped with a fish slide connected to the drainage bottom. Its area is approximately the total area of the bottom of the pond and is deeper than the bottom of the pond. The fish slide should be surrounded by wooden boards or built with cement masonry.
Preparation before stocking: The day before the loach is stocked, clean the loach pond, plug the leaks, dredge the inlet and drainage pipes, plow the silt at the bottom of the pond, and then use quicklime to clear the pond, that is, apply / square meter of quicklime when the water is deep. After the quicklime is mixed with water and turned into a slurry, it is immediately poured evenly over the entire pool. After clearing the pond, add water to the pond and apply base fertilizer. The base fertilizer can be fermented chicken manure/square meter, or fermented human manure, pig manure, cow manure, etc./square meter to cultivate plankton in the pond water so that loaches can be planted in the lower pond. Then you can eat palatable basic food organisms.
Before stocking loach seeds, disinfect them with a bleaching powder solution of ~, and soak them in water for 1 to 3 minutes when the water temperature is between ℃ and ℃. The stocking density of loach species with a body length of ~100cm/m² is 1/m2 to 1/m2/m2. When the water source conditions and technical strength are good, the stocking amount can be increased appropriately. In Taiwan loach breeding ponds, some fish species that live in the middle and upper layers of the water body can also be appropriately stocked, such as grass carp, silver carp, bighead carp and other summer fish species. It is not suitable to stock tilapia, carp, crucian carp and other species.
Fertilizing Taiwan loach is an omnivorous fish and likes to eat organic debris and plankton benthic animals. Therefore, fertilization measures should be taken during the adult loach breeding stage to cultivate basic feed organisms in the pond water. In addition to the application of base fertilizer, top dressing should also be timely based on the water color. Fermented pig manure, cow manure, chicken manure, human manure and other farm fertilizers are commonly used for top dressing. Chemical fertilizers such as calcium superphosphate, urea and ammonium bicarbonate can also be applied. The amount of top dressing depends on the water color. The dosage is For basal fertilizer, control the transparency of the pool water. The water color should be yellow-green.
Feeding Taiwan loach has a wide range of food habits. In addition to fertilizer and water, compound feed should also be fed during breeding. The appetite of the Taiwan loach is related to the water temperature. When the water temperature is below ℃, it mainly eats plant feed, accounting for about ~ %. When the water temperature is between ℃ and ℃, it eats animal and plant feed in a proportion of each. When the water temperature exceeds ℃, it eats plant feed. The proportion should be reduced to ~. Animal feeds for Taiwanese loaches include fish meal, offal, earthworms, small fish, blood meal, etc. Plant feeds include soybean meal, rapeseed meal, flour, wheat bran, cereals, etc. Artificial compound feeds can also be fed, feeding times per day, daily feeding amount It is the total weight of Taiwanese loach, and the amount of feeding should be flexibly controlled according to the water quality, weather, feeding conditions of Taiwanese loach and other conditions. When the water temperature is above ℃, the appetite of Taiwanese loach gradually increases, and when the water temperature is between ℃ and ℃, the appetite is particularly strong. When the water temperature exceeds ℃ or falls below ℃, it should be fed less or even stopped. The feed needs to be fed at a fixed time, at a fixed point, with a certain quality and quantity.
