Growth stage of tadpoles

Pre-growth period (1 ~ 10 days): tadpoles are not fed for three days after hatching, and they rely on the nutrition brought by egg yolk to maintain their lives, but premature feeding will lead to death.

Early growth period (10 ~ 20 days): After 10 days, the food intake of tadpoles increased and their growth and development accelerated. Tadpoles began to look for new food, but their digestive function was still not strong. At this time, the quality of feeding directly affects the survival rate of tadpoles.

Mid-growth period (20-50 days): At this time, the digestive function of tadpoles is constantly enhanced. In order to promote the development of tadpoles' digestive tract as soon as possible and adapt to the biological characteristics of herbivores in amphibians' specific tadpoles, tadpoles after 20 days should be fed with plant feed and algae plants, such as duckweed, in addition to pasty bait.

Late growth period (50 ~ 78 days): This period is the key period for tadpoles to transform into young frogs. During this period, tadpoles will grow hind limbs and forelimbs, transforming from aquatic to amphibious. About 50 days, the body length is more than 4cm, and the hind limbs grow out. After the hind limbs grow out, the forelimbs begin to grow. After the forelimbs grow, the tail begins to be absorbed. At this time, Shi Wa tadpoles stopped eating and entered the metamorphosis period.
