How to feed the baby fish

The salamander, also known as the giant salamander, likes carnivorous, and its natural bait includes crabs, fish, frogs, snakes, soft-shelled turtles, water birds, water rats, water centipedes and other aquatic insects. When food is scarce, smaller congeners are also eaten. Juvenile salamanders feed on aquatic insects and larger zooplankton, and also on earthworms.

Giant salamanders have a strong digestive ability, and crab shells can also digest them. Giant salamanders are hungry and will not starve to death if they are not fed for months or even longer. When raising giant salamanders in captivity, they can be fed chickens, ducks and other poultry offal, as well as earthworms, small fish, small shrimp, snails, tadpoles, frogs, etc.

The feeding skills of the baby fish are to manage the water, control the water temperature, and pay attention to avoid light.

1. Raising baby fish.

Scientific and reasonable pond construction: after the breeding site is determined, the shade, light, management and water inlet and outlet convenience should be selected to build the breeding pond. The breeding pond generally adopts a brick-concrete structure, and the area of each small pond is determined according to the size of the baby fish, 1 2 square meters per hour, 2 4 square meters when large, and the pool shape is not limited, but the height of the pool needs to be more than 1 meter.

Seed and seedling stocking: because the baby fish has the best aggressive life habits, especially the adult baby fish, when they feel hungry due to lack of food, they often bite at night, the light ones are injured, and the heavy ones even bite the baby baby fish to death and swallow them, so the farmed baby fish must be classified according to the size and strength of the stocking, and the appropriate thinning. Generally, according to the size of the breeding pond and the fry, each pond is put into 5 10 baby fry of the same specification, and the fish can be dense and large when it is scarce.

2. Feeding skills of baby fish.

Manage the water: always keep the pool with a slight flow of water, the pool water is fresh, pollution-free, high dissolved oxygen content, and maintain an appropriate water level, not only to prevent the pool from drying, but also to prevent the water from escaping.

Control the water temperature: especially in the high temperature season, it is necessary to strengthen the water change, so that the water temperature is always kept below 25.

Pay attention to avoid light: when the sun is strong, the shade should be set up in time to prevent strong light from directly hitting the breeding pond.

The habits of the baby fish

Baby fish generally inhabits the caves and stone caves in the deep pools of rivers below 1000 meters above sea level, and are more common in the caves above and below the beach mouth, and the hole is not big, and it enters and exits a mouth; The depth of the cave varies, and the inside of the cave is spacious and flat. During the day, they often lie in the cave, rarely go out to do orange rough activities, and in summer and autumn, they also have the habit of going ashore to forage for food or bask in the sun during the day. Giant salamanders generally come out at night and return in the morning, and often live in a cave.

Predation is mainly carried out at night, often waiting among the rocks at the beach mouth, and suddenly opening its mouth to hunt when it finds a huntable animal passing by.

Giant salamanders are suitable for inhabiting water with a water temperature of 3 23, and the large individuals mostly live in deep water, and the small and medium-sized individuals mostly live in shallow water. Most of the salamanders are monophytic, and the juvenile salamanders often gather in the crevices of the rocks, and the optimal water temperature for their life is 10 20.

The giant salamander often stretches its head to the surface of the water to breathe, and it is also an important organ for gas exchange, and in water with high oxygen content, the giant salamander can lie on the bottom of the water for a long time without surfacing to breathe. In captivity, breathe every 6 30 minutes with your nostrils out of the water and inhale for about a few seconds to 10 seconds.

The baby fish feeding tips are as follows:

Fish tank: first of all, we must raise baby fish to find a nest for it, that is, the fish tank, must be large, to the kind of "villa-style fish tank", it is best to decorate, dress up as its suitable ecological environment, the bottom of the tank can be paved with some clean sand and gravel, place a small amount of goldfish algae aquatic plants, so that the sand and gravel can adsorb dirt, aquatic plants can carry out photosynthesis, increase the oxygen content in the water, kill two birds with one stone.

Water quality: baby fish is a love clean and afraid of dirty baby, the water quality requirements are relatively high, can not directly use tap water, to use clean pool water or well water, must use tap water, must be dried for three or five days, anyway, clear, fresh, pollution-free, high dissolved oxygen, pH value is neutral no problem. In addition to changing the water frequently to keep the water quality fresh, you can also use quicklime to adjust it on time, and you can also maintain the fluidity of the water brigade, it is recommended to change the water once every three to five weeks in winter, and once every three to five days in other seasons.

Other requirements

Water temperature: to be the most suitable for the growth of the baby fish water temperature, can not be too high nor too low, the best between 16-23, generally 19 best, the baby fish is afraid of heat and cold, the temperature must not be too high, the baby fish likes to be quiet and easy to be frightened, so the environment is quiet and better for raising it, in addition, the baby fish is afraid of the sun, can not let the sun directly to it.

Food: Baby fish like to eat live food rocks, like earthworms, tadpoles, daphnia and the like are baby fish like food, baby fish is meat, can also be fed small pieces of lean pork, but pay attention to the amount, do not have leftover to prevent food decay and affect the water quality, it is best to eat a small amount of times, on time and on point feeding is the best.

Cleaning: The container for raising baby fish should be cleaned every day, especially its excrement should be cleaned up in time to maintain the quality of the water; The container for raising baby fish needs to be cleaned once a month, and it needs to be disinfected once a week.

Raising baby fish requires water temperature and light conditions. Feeding baby fish requires the right bait, good water quality, and the right temperature and light.

It is better to choose natural bait, once in the morning and once in the evening, and then clean up the water quality in time to ensure that the water is clean and the oxygen is sufficient. In addition, it is necessary to maintain the right temperature to facilitate the healthy growth of the salamander, and at the same time, it is also necessary to avoid strong direct sunlight.

The salamander is a tailed amphibian of the family Cryptochillidae and the giant salamander. The body is large and flattened, generally 582 834 mm in length, 310 585 mm in length in the head and body, and the maximum individual can reach more than 200 cm in length.

The head is large, flat and broad, the head length is slightly greater than the head width; The male salamander has a raised anus, oval, large anal hole, and small milky white particles on the inner wall; The female salamander has no bulge in the anus, the cloaca anal hole is small, the periphery is concave inward, the inner wall of the hole is smooth, and there are no milky white small particles.

Adult salamanders generally inhabit the caves and stone caves in the deep pools of rivers below 1000 meters above sea level, and are more common in the caves above and below the beach mouth, and have a wide range of feeding habits, mainly feeding on crabs, frogs, fish, shrimp and aquatic insects, and their larvae.

It is mainly distributed in Hebei, Henan, Shanxi, Shaanxi, Gansu, Qinghai, Sichuan, Chongqing, Guizhou, Yunnan, Hubei, Anhui, Jiangsu, Shanghai, Zhejiang, Jiangxi, Hunan, Fujian, Guangdong and Guangxi in China.

The giant salamander is an ancient amphibian that evolved from aquatic fish during the Devonian period of the Paleozoic Era, 360 million years ago.

Raising and feeding skills of baby fish: feed, water temperature, light, and water quality.

1. Feed

Most of the salamanders feed on natural feed, mainly plankton, insects, meat, fish, shellfish, etc. The bait is cast once a day in the morning and once in the evening, before 7:30 a.m. and 10 p.m

Before 30 is better. When feeding the bait, you should first clean up the bait residue from the last time. The feeding amount is 5-10% of body weight.

When the water temperature is 16-23, the amount of bait should be increased, and the frequency and time can be kept unchanged.

2. Water temperature and light

In order to ensure that the salamander has a suitable water temperature growth environment, it is best to choose a closed cave or room, avoid light, and do not have direct strong light during inspection, the water temperature is not lower than the freezing temperature, not higher than 26 degrees, and it is necessary to keep warm in winter and cool down in summer, otherwise the salamander will enter a dormant state.

3. Water quality

For salamanders, the most important thing is to have good water quality, after each feeding, to remove the residue, clean up the excrement, regularly adjust the water quality with quicklime, and keep the pool water flowing for a long time.

Baby fish

The salamander, also known as the giant salamander, is the largest and most precious amphibian in the world. Its cry is like a baby's cry, so people call it "baby fish" again, baby fish likes dark, cool, flowing water environment, its feeding is extensive, the larvae feed on zooplankton, aquatic insects, as the individual grows up, gradually prey on tadpoles, frogs, fish, crabs, and even water birds, mutton can be eaten.
