Longchuan Rice Field Fish

Longchuan Rice Field Fish

　　Longchuan Rice Field Fish is a specialty of Longchuan County in Dehong Prefecture, Yunnan Province.

　　Rice field fish farming is an efficient, low-consumption modern ecological agricultural production model that requires minimal investment, has a short cycle, and yields quick results. It leverages the mutually beneficial relationship between rice and fish, makes full use of land resources, and organically integrates crop cultivation with aquaculture. To further maximize the economic, social, and ecological benefits of rice field fish farming, accelerate rural poverty alleviation and prosperity, foster new sources of rural economic growth, and achieve the goals of increasing farmers’ income and boosting the rural economy, in line with the county’s actual conditions, the Longchuan County Aquatic Products Station implemented a rice–fish project demonstration area covering 1,939 mu. The goal was to achieve an average yield of over 80 kilograms per mu. The field engineering was designed in trench–pond or pond–field styles, with fish trenches dug in cross (“十”), hash (“﹟”), or T-shaped patterns.

　　Since the beginning of spring, the aquatic products station has actively organized all technical personnel to conduct extensive publicity, mobilization, and technical training for suitable rice fields through various means. As of June 30, a total of 10 on-site technical training sessions were held, with 564 participants, over 1,000 technical materials distributed, and 4 screenings of rice field fish farming technique videos. The county completed a rice–fish project demonstration area of 1,856 mu; native “picking fish” (挑手鱼) were farmed in 83 mu of rice fields. These were mainly distributed across townships (towns) such as Zhangfeng, Jinghan, Chengzi, Longba, and Qingping, with a total of 4,150 native picking fish released. Additionally, 27,090 kilograms (325,080 individuals) of various high-quality, large-sized fish species were introduced, primarily including Southwest carp, monosex tilapia, gynogenetic silver crucian carp, and lotus carp. Currently, both the rice and fish are growing well, and a bountiful harvest of both rice and fish is expected in autumn.
