Loach breeding technology: basic conditions, pond cleaning, disinfection and sterilization, and maintenance.
1. Basic conditions: sufficient water sources, fresh water, and no environmental pollution such as chemical fertilizers. The inlet and drainage pipes are convenient, and the inlet and drainage equipment are required to be separated. The bottom is neutral or acidic. The surrounding environment of the farm is comfortable and the power supply system equipment is normal. It has complete infrastructure facilities such as hydropower projects and a strategic location.
2. Clear pond disinfection and sterilization: use 100kg-150kg of lime powder per acre more than 15 days before planting seedlings to eliminate pathogenic bacteria and improve the bottom mud. In the fourth month of stocking, drain the water in the pond and turn it over for sufficient air oxidation and exposure. The exposure time must be more than 1 month.
3. Maintenance: During the breeding period of loach, the water in the fish tank must be changed regularly to maintain the clarity of the water at about 30 centimeters. The bait table should be cleaned daily to reduce bacterial growth. The water temperature should be maintained at 22 -28 degrees is the best. At the same time, during the breeding season of loaches, fish roe should be scooped up immediately after the parent loaches lay eggs to prevent them from being swallowed by loaches.
Characteristics of the loach
The body of the loach is small and slender, with a sub-cylindrical front end, a round abdomen, and flat sides at the rear end. The ratio of body height to body length is 1.7:8. Head: The head of the loach is pointed, the snout protrudes forward, the angle of inclination is large, and the length of the snout is shorter than the length of the head behind the eyes. The mouth is small, sub-inferior, and horseshoe-shaped. The lips are soft, with fine wrinkles and small protrusions. The eyes are small, covered with membrane, and the upper and lateral vision is underdeveloped. The gill slit ends at the base of the pectoral fin.
The loach’s body surface is rich in mucus. The back of the body and more than 2/3 of the sides are gray-black with black spots, and the lower half of the body is gray-white or light yellow. Loaches living in different environments have slightly different body colors.
