Farming technology

The economic feasibility of aquaculture, also known as "cricket farming," is gaining attention due to its high profitability and low input costs. This practice involves raising crickets for their medicinal value, particularly the secretion from their parotid glands, which has been used in traditional Chinese medicine for centuries. Cricket secretions are valued for their detoxifying, anti-inflammatory, and analgesic properties. They are commonly used in treating various ailments such as cancer, tuberculosis, and chronic respiratory diseases. The secretions contain bioactive compounds that support immune function, promote wound healing, and have shown potential in fighting certain types of cancer. These properties make them a key ingredient in several proprietary medicines, including Liushen Pills and Red Dan Ling. In terms of economic benefits, cricket farming is an ideal option for small-scale farmers. It requires minimal investment and can be conducted using existing land, such as ponds, gardens, or sloped areas. Crickets can be fed on organic waste, including pig manure, vegetable scraps, and food factory byproducts, making it a sustainable and cost-effective operation. A two-year-old cricket can produce more than six batches of secretion during the summer and autumn months, with each batch yielding around 500 grams of fresh material over six months. Market demand for these products is strong, with prices ranging between 1,800 to 2,800 yuan per kilogram. This makes cricket farming not only profitable but also a viable alternative to traditional livestock farming. However, there are important precautions to consider when breeding crickets. Pesticides and other toxins must be strictly avoided, as they can poison the crickets. Feeding carnivorous animals like chickens or ducks in the same area should also be prohibited to prevent predation. During the collection and processing stages, contact with iron should be avoided, as it can cause discoloration and reduce product quality. If the glands are empty after collection, the crickets should be released back into the environment to ensure continued reproduction. Before starting, proper infrastructure must be set up. A one-meter-high fence should surround the breeding area, with designated ponds for rearing, spawning, and hatching. Lighting systems should be installed to attract insects at night, and the ponds should be equipped with drainage systems for easy cleaning. For feeding, simple tools like bamboo clips or copper clips can be used to collect the secretion efficiently. These clips are made by splitting a bamboo tube, attaching hinges, and adding a tension spring to allow for easy opening and closing. Feeding larvae is straightforward—using organic waste to create plankton, which serves as a nutritious food source. Additionally, planting vegetation and using light to attract insects can help sustain the population naturally. When collecting the secretion, it's crucial to handle the crickets carefully. Only healthy, adult crickets weighing over 80 grams should be selected. The process should be done in a clean, well-ventilated area, and the temperature should ideally be around 20°C. The best time for collection is from April to October, though indoor farming with artificial heating is also possible. It’s important to note that some individuals may exploit this industry by offering false training or selling substandard equipment. Farmers should be cautious and verify the credibility of any service provider before investing. Artificial breeding involves setting up suitable habitats, maintaining proper humidity and temperature levels, and ensuring adequate nutrition for the crickets. Eggs are laid in large quantities, and with proper incubation techniques, the hatch rate can be significantly improved. Processing the collected secretion involves careful handling to avoid contamination. The material should be scraped into a ball, kneaded, and formed into a flat cake. Drying is done using white cloth, and care must be taken to avoid contact with metal, as it can cause discoloration. Once dried, the product becomes a valuable traditional remedy. Overall, cricket farming offers a promising opportunity for those looking to enter the medicinal agriculture sector. With proper knowledge, infrastructure, and attention to detail, it can be both economically rewarding and environmentally sustainable.
