Modern research has also shown that many herbal extracts possess antioxidant, anti-inflammatory, anti-bacterial and anti-tumour activities, which have a positive impact on human health.
Mud farming practical technology
The loach is a versatile and resilient fish species, commonly found in freshwater environments. Known for its strong vitality, rapid reproduction, and adaptable diet, it is one of the most popular fish for aquaculture. Its meat is not only delicious but also highly nutritious, rich in protein, fat, vitamins like riboflavin, and minerals such as phosphorus and iron. In traditional medicine, loaches are believed to have therapeutic effects on conditions like facial spasms and mumps. Additionally, they are a significant export commodity, especially in regions where small-scale aquaculture is prevalent, such as garden ponds and pit farms.
Loaches have a streamlined body that becomes more flat as they grow. Their eyes are small, their mouths are downturned, and they possess five pairs of barbels around the mouth. The skin is covered with tiny, embedded scales, and the pectoral and caudal fins often have dark spots at their base. Their coloration is typically grayish-black with irregular black patches, which can vary depending on the environment. The belly is lighter in color and filled with moisture, giving them a plump appearance.
These bottom-dwelling fish prefer still or slow-moving waters with soft mud. They thrive in temperatures between 15°C and 30°C, with an optimal range of 25°C to 27°C. When water temperatures drop below 5°C or rise above 35°C, or during dry periods, they burrow into the mud to enter a dormant state. As long as the soil remains moist, they can survive without water for extended periods.
One unique characteristic of loaches is their ability to breathe through both their gills and their intestines, allowing them to survive in low-oxygen environments. When oxygen levels drop, they surface to inhale air, absorb oxygen through their intestines, and expel waste through their anus. Another notable trait is their tendency to escape. If there's even a small opening in their enclosure, they can easily escape, especially during rainy weather or high water levels. This makes preventing escapes a crucial aspect of loach farming.
Loaches are omnivorous, feeding on a wide range of food sources. Juveniles under 5 cm primarily consume zooplankton like cladocerans. As they grow, they transition to eating crustaceans, insect larvae, silkworms, algae, plant matter, and organic debris. Once they exceed 8 cm in length, they mainly feed on plant-based materials such as diatoms, roots, leaves, and seeds. They are known to be very hungry, often feeding at night, and especially during spawning and growth seasons.
Mature loaches typically reach sexual maturity within two years. Spawning occurs from April to September, peaking between May and July, with an ideal temperature of 25°C to 26°C. During spawning, males wrap around females, pressing their abdomens to release eggs, while simultaneously releasing sperm for external fertilization. Eggs are laid in shallow waters, ditches, rice fields, and among aquatic plants. The eggs are yellow, oval-shaped, and not strongly adhesive.
There are several methods for breeding loaches. Natural spawning involves using spawning pools with artificial nests made of submerged branches and aquatic plants. Once eggs are laid, they are moved to hatching ponds. Artificial breeding uses hormones like PG or LRH-A5 to stimulate spawning, allowing for controlled and large-scale production. Another method is to introduce mature loaches into rearing areas with artificial nests, allowing them to spawn naturally.
In terms of aquaculture, loaches can be raised in specialized ponds, rice paddies, or even in family settings. Ponds should have soft mud, and proper feeding with organic matter like rice bran, bean cake, and livestock manure is essential. Rice field farming is particularly effective, as loaches can survive even when water is drained, using their skin and intestinal respiration. Family-level breeding is also common, using small containers or reservoirs behind homes.
Fishing loaches can be challenging due to their burrowing habits. Methods include flushing them out with water, using bait traps, or draining ponds in autumn to capture them from the mud. Proper holding and transportation techniques are necessary to maintain quality. Loaches can be kept in bamboo rafts or wooden barrels, with regular water changes to ensure freshness. For transport, nylon bags with oxygenation are commonly used, especially for long distances.
Disease prevention is critical in loach farming. Common ailments include red fin disease, fungal infections, and parasitic infestations. Treatments involve antibiotics, salt baths, and chemical treatments. Preventive measures include maintaining clean water, avoiding overstocking, and controlling pesticide use. Regular monitoring and proper management are key to successful loach farming.
