The process of feeding and fasting begins with the development of limbs in the cockroach and the introduction of cockroaches into pool water as bait. By observing daily, both day and night, dragonflies were seen to land in their active areas and on the water's surface. Every night, incandescent lights were used to attract flying insects for predation. However, every week, light trapping was paused for one night to allow intermittent feeding, which helped reduce fat accumulation and promote skeletal and gonadal growth. At 18 to 30 months of age, this practice was adjusted—light traps were stopped every 10 days for two nights. Then, after a sudden interruption of food supply, the dragonflies were allowed to fast for two days and nights, preventing their gonads from becoming overloaded with fat, which could delay reproduction, lower egg production, or even cause infertility.
Before and after 18 months of age, a floating feeding table was introduced. A 0.5-meter square wooden board (1 cm thick) was placed on the water surface, where bait such as insects was placed. This encouraged cormorants to climb onto the board to feed, jump into the water, push the board, chase it, and develop their ability to adapt between aquatic and terrestrial environments. The floating board did not occupy land or reduce water volume; instead, it provided shade and a sense of security by allowing the dragonflies to hide behind it. This significantly improved their overall survival strength and physical endurance.
In the late stages, broad-leaved vegetables were planted in loquat areas to control pests and produce green vegetables. During the day, the leaves of these vegetables were used to provide shade, creating a more natural and comfortable environment. From 30 to 36 months of age, nighttime lighting was switched to black light traps, encouraging dragonflies to live primarily in darkness. As nocturnal creatures, they are naturally adapted to feeding, growing, mating, and laying eggs in low-light conditions. This shift accelerated the development of their phlegm and gonads.
Artificial assistance was also used to enhance physiological and reproductive development. Starting when the limbs began to grow, the molting process (a natural phenomenon often referred to in traditional Chinese medicine) became evident. In nature, skin growth increased about three times per year, with one molt occurring per cycle. Before 30 months of age, molting was synchronized with general growth. After that, it aligned with the development of the internal gonads. Through artificial methods, the number of molts could be increased to over 14 times per year, intensifying the stimulation of physiological and reproductive growth. With sufficient nutrition, these individuals could lay eggs up to five months earlier than their naturally developed counterparts.
