Fly larvae feeding jaundice technology
The peak of Astragalus consumption coincides with the height of fly breeding season. During this time, it's essential to stir the potatoes and bran thoroughly. Add items such as dead fish, smelly fish, pig's urine, sheep's urine, fish eggs, or fish intestines—anything that emits a strong odor. Place these attractants in black jars or porcelain containers, which absorb heat and light quickly, making them ideal for luring flies to lay eggs. The jars should remain undisturbed for a while before being emptied into pots. Mix the contents with some ash and gently stir for a few minutes. Then tilt the pot, allowing the maggots to crawl out. Carefully sweep the cockroaches from the pot, rinse them, and they can be used to feed yellow mealworms. Alternatively, you can place rows of black crock tanks directly on the surface of the Huangqian Pool. As the maggots grow, they will naturally climb out and fall into the water, where they can be fed to clams. You can also make an attractant using bean dregs mixed with a small amount of human waste. After some time, it’s important to replace the contents of the jars to maintain a strong, rancid smell that continues to attract flies.
During the cold winter months, raising flies in a greenhouse is both economical and practical, allowing for the hatching and feeding of yellow trout. This method ensures a steady supply of food even when outdoor conditions are unfavorable.
While the previous method is simple and effective for raising earthworms, its yield is limited, and there's a risk of bacterial contamination. In the following section, we'll introduce a more advanced technique for breeding fly larvae with higher productivity, scientific management, and better hygiene control.
The bait used for feeding is prepared by washing and disinfecting the material, then adding 5% Yeast. Alternatively, mix 100 grams of wheat bran, 1 gram of milk powder, and 200 ml of water. For raising quails, the base material is a culture medium containing 65% moisture, made by mixing pig manure with an appropriate amount of wheat bran and a solution of ammonium carbonate at a concentration of 0.01% to 0.03%.
It is best to obtain sterile fly cultures from research institutions or specialized farms. If wild flies are used, they can be sterilized by placing them in a jar filled with 10% water, then introducing the larvae. Soak the larvae in potassium permanganate solution for two minutes, select the plump ones, and place them in a fly cage. Once they hatch, they become sterile seed flies.
Fly cages are typically made of wire mesh and iron frames, with a small hole on one side for handling. A long black cloth cover is attached to the hole and kept closed. When entering the cage, the cloth can be lifted to prevent the flies from escaping. The cages should be kept indoors at a temperature of 27–29°C. Each cage should contain a cup of clean water, two small dishes (one with brown sugar and one with flour), a small rice bowl, and a spawning cylinder filled with the egg-laying medium. A glass jar is also placed inside as a hatching container. Every morning, remove the bait dishes and replace them with fresh material, and add 50 grams of red peony every three days. Flies are removed after 20 days, and the cages and nets are cleaned with sterilized water for reuse.
Maggots are raised in plastic pots. The base material is placed 3–5 cm deep at the bottom of the pot, but no more than 3 cm in summer. After collecting the eggs from the fly cages, mix the base material with the eggs at a rate of 5 grams per kilogram of base. Place the pots at 22–25°C, maintaining a humidity level of 70–80%. After 8–12 hours, the maggots will hatch. They can be used as bait on the fourth day and changed on the fifth.
To separate the maggots and avoid overheating, place the pots under sunlight or bright light. The worms will soon burrow to the bottom. At this point, scrape off the top layer of the base material, pour the rest through a fine sieve, and wash repeatedly in water to obtain clean fly larvae.
