The development of small pond fish culture in mountainous area has great potential

Introduction: the development of family style small pond fish culture in the mountain area without fish pond can not only solve the problem of people eating fish in the mountain area, but also be a good way to get rich The fish culture technology in small pond in mountain area is simple and easy to operate, and the management is also convenient Excavate or repair small ponds with tens of square meters in small scale and hundreds of square meters in large scale by using the places with water sources in the front and back of the village or in the courtyard The water depth is about 1-1.5 meters The walls of the ponds should be built with bricks to prevent the collapse of Nisha If possible, bamboo tubes can be used to lead the mountains and rivers into the ponds for up irrigation and down drainage, usually keeping the water depth about 1.2 meters Generally, grass carp (grass carp) is the main forage fish, and it is suitable to be mixed with carp, crucian carp, dace, pond lice and other fish Put 2 grass carp species of more than 250g per square meter, 100 grass carp in 50 square meters, and match with 3-5 carp and crucian carp to eat the excrement excreted by grass carp Xiaotang fish feed is also easy to solve It can be used to cut some field-based tender grass, peanut stem, sugarcane, cassava leaves and other green feed when going out, or use some vegetable leaves and the rest of the family's vegetable head, vegetable feet and scattered cattle grass as grass carp feed, while carp, crucian carp and other fish eat grass carp feces, so as to achieve interaction and promote growth In a word, if we plant in that year, we can get results in that year Good management, the output per mu can reach hundreds or even thousands of kilograms, this small pond fish culture is not only particularly suitable for the vast mountainous areas, but also suitable for many rural plain areas According to the practice, the development of small pond fish culture in rural families in mountainous areas will achieve better results Located in zhainan Town, Liannan Yao Autonomous County, which is located in the deep mountains of northern Guangdong Province, local farmers have made use of the advantages of long flowing mountains and rivers and more green fodder to actively develop small pond fish culture and achieved remarkable results In 2000, 1120 farmers in the town raised small pond fish, accounting for 70% of the total farmers There are more than 1700 small ponds, covering an area of 153 mu Last year, a total of 135 tons of high-quality grass carp were listed, with a total output value of 3.12 million yuan and an average income of 2710 yuan per household Due to the low cost, the average net income per household is more than 2600 yuan, with the highest income of 5200 yuan The water quality of fish raised in Xiaotang is fresh, the oxygen is sufficient, grass carp grows fast and grows easily It has been raised for more than five months, with a tail weight of 3kg-4kg in general, and it is not polluted The meat is tender, which is favored by consumers Hotels, restaurants and large stalls in neighboring cities and towns send people to buy it every morning There are also merchants from distant Shaoguan City and other places This kind of fish farming method with low cost, quick effect and good income is called "a small fishing pond at home, like a small bank" It is said that this kind of fish farming began in the Song Dynasty However, the current methods, varieties and management methods of fish culture in small ponds have been greatly improved Xiaotang is suitable for fish farming in mountainous areas It has many advantages It does not occupy cultivated land, do not invest in fishing pond construction, and does not need to spend money on feed It only needs to spend a small amount of money on fish species In addition, the small pond is convenient for fish management, with high yield and good benefit It can also be used comprehensively Duck can be raised on the water surface and melon and vegetable can be planted on the top Therefore, some people describe Xiaotang fish farming as a "cash cow" for rural families The farmers in the vast mountainous areas have great potential to develop Xiaotang fish farming, and the prospect is broad.
