What food does tadpoles eat?
Tadpoles mostly feed on algae with rows of horny teeth in their mouths, but if there are some small animal carcasses such as earthworms and beetles in the water, they will also eat them in droves. Some kinds of tadpoles have no horny teeth, such as rain frog and black muncie rain frog, but they feed on plankton in filtered water. In addition, the tadpoles of ehrlich, a tree frog, eat eggs, and the female frog will come back regularly to lay eggs and feed the tadpoles. In the case of insufficient food, there will also be a phenomenon that big tadpoles eat small tadpoles and kill each other. If you feed yourself, give them bread crumbs. If it is natural in the pond, it usually feeds on mosquito larvae, plankton, fish and insects in the water.
Feeding management of tadpoles
Tadpoles should be raised in grades, and tadpoles on the same day should be graded according to individual size, once a month/kloc-0, which is beneficial to unified feeding management. Reasonable control of feeding density, grouping and combination in the process of grading, and appropriate individual density in the same level are fed in different pools. Feed should be varied and of high quality, and the reasonable feeding amount should be mastered correctly, neither too little nor too much. Feed at a fixed point once a day, and the amount of each feeding should be balanced, and gradually increase appropriately with age. During the peak feeding period or before and after metamorphosis of tadpoles, strict feeding management should be done to prevent the occurrence of various diseases or unnecessary losses caused by unsuitable environmental conditions.
Growth stage of tadpoles
1, initial growth period (1 ~ 10 days): tadpoles are not fed for three days after hatching, and they live on the nutrition brought by egg yolk, but feeding them too early will lead to their death. After three days, the activity of tadpoles increased obviously, and they began to feed when the gill cover was completely formed. Feed them an egg yolk for every ten thousand tadpoles at regular intervals, and add some natural plankton in the water, such as Daphnia and algae.
2. Early growth stage (10 ~ 20 days): After 10 days, tadpoles increased their food intake, accelerated their growth and 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. Therefore, in order to meet the needs of its growth and development, it is necessary to supplement bait when feeding, mainly with nutritious paste bait, such as egg yolk, corn flour, No.4 powder, etc., supplemented by delicate algae plants.
3. Mid-growing period (20-50 days): The digestive function of tadpoles is constantly enhanced in the middle growing period. In order to promote the development of tadpoles' digestive tract as soon as possible and adapt to the herbivorous biological characteristics of amphibian tadpoles in a certain period, tadpoles after 20 days of age should be fed with plant feed and algae plants, such as duckweed.
4. Late growth period (50 ~ 78 days): The late growth period is the key period for tadpoles to transform into young frogs, during which hind limbs and forelimbs will grow and transform from aquatic to amphibious. During this period, in addition to feeding enough feed, a small amount of animal live bait feed should be added.
