Loach farming has strong adaptability; mastering the methods and daily management is key

The loach is a common small freshwater economic fish, with a slender, smooth body and skin rich in mucus. It likes to inhabit the bottom mud of shallow waters such as ponds, ditches and rice paddies. Because its flesh is tender and nutritious, it has long been known among the people as the ginseng of the water, and loach farming has therefore become a popular aquaculture project in many regions.

The loach has strong adaptability. Besides breathing with its gills, it can also use its skin and intestines to assist respiration. It tolerates low oxygen and hunger, and its requirements for water quality are not particularly strict. It has omnivorous feeding habits: it can feed on plankton and organic debris in the water, and it also accepts artificial compound feed. It grows fairly quickly, and the farming cycle is relatively short. However, the loach has the habit of burrowing into mud and escaping, so escape-prevention facilities must be well installed when farming it.

Common farming methods include pond culture, cement-pond culture, cage culture and rice-paddy co-culture, among others. Before releasing the fry, the pond is generally cleared, disinfected and fertilized to cultivate water quality; robust fry are selected, and a reasonable stocking density is controlled. Daily management mainly consists of feeding, patrolling the pond and changing the water, keeping the water fertile but not turbid and avoiding deterioration of the water body that would affect loach growth.

During the farming process, attention must also be paid to disease prevention. Normally, observe the loach's activity and feeding conditions more often, and deal with any abnormality promptly. In the high-temperature season, pay attention to aeration and shading, while in winter, do a good job of overwintering and heat preservation. Overall, loach farming requires moderate investment and relatively simple management; as long as the methods are appropriate, it is an aquaculture project suitable for ordinary farmers to try.
