Does the amphibian baby fish eat pork? What kind of food or feed did you grow up on? Recommendations for edible food

Baby fish, also known as giant salamander, is a common amphibian in Guangdong, Guangxi, Fujian, Sichuan, Guizhou, Hubei and other places. It is named because it sounds like a baby crying. It is a carnivore. Does the baby fish eat pork? What kind of food or feed did you grow up on? Recommended food to eat.

First, the predation habits of baby fish:

Dollfish like to hunt at night and usually wait quietly to hunt food in the rocks at the mouth of the beach. once they find their prey passing by, they will suddenly attack, but once the food they ingest, it is very difficult to escape, because the dollfish's teeth are sharp and dense, so the escape is very small. In addition, baby fish can tolerate hunger and will not starve to death even if they are kept in cool water for two or three years without eating. At the same time, you can also overeat, and a good meal can increase your weight by 1/5. When there is a lack of food, there will be cannibalism of the same kind, and even satisfy hunger with eggs. Usually hide, like the color of the body and the surrounding stones to avoid natural enemies.

Second, what to eat?

1. Edible food

Baby fish are ferocious by nature and are carnivorous animals. They often feed on aquatic insects, fish, shrimp, crabs, soft-shelled turtles, frogs, snakes, birds, rats, and so on. The way of predation is to "wait for the rabbit". The teeth cannot be chewed, but the food is swallowed whole with open mouth. and then digest it slowly in the stomach. Artificial feeding with natural bait is better, mainly fish, insects, plankton, meat, shellfish and so on.

(1) specific foods that can be eaten by wild baby fish:

① earthworms: water earthworms are ideal fodder, which can be put into a small amount every other day. Water earthworms can also be wrapped in a single layer of gauze and hung in the water with ropes. Water earthworms will protrude part of their bodies from the gaps in the gauze, and salamanders will swim to pull food.

② tadpoles: tadpoles are the larvae of amphibians such as frogs, toads, salamanders and salamanders, also known as toad eggs.

③ water flea: commonly known as fish and insect. Except for a few living in sea water, most of them are the most common zooplankton in all kinds of freshwater waters, and they are excellent bait for fish.

④ larvae (mosquito larvae), formed from mosquito eggs hatched in the water, have a slender body, a wider chest than the head and abdomen, and a flexion and extension of the body when swimming, commonly known as the head worm.

(2) specific foods that can be eaten by farmed baby fish:

Baby fish mainly eat some insects and meat, in artificial culture, farmers can catch some animal bait from ditches, ponds and other places as bait for baby fish.

① naked belly diffuse growth in ponds, rivers, puddles, reservoirs and other fresh water, its wide distribution, large number, strong fecundity, a large number of two floating on the surface, forming a red color. So it's also known as the red bug.

② pork: when there is a lack of active small animals, lean pork can also be cut into small pieces for feeding. However, attention should be paid to not taking too much food, and it is appropriate to have no residual food to prevent the food from rotting and affecting the water quality.

(3) what do baby fish eat?

Baby fish are relatively small, so when feeding, try to choose small food, such as shrimp, egg yolk, red nematode, larva and other aquatic insect larvae in the stream. In addition, it is necessary to choose bait that is easy to digest and try not to feed those that are too greasy.

2. Edible feed

(1) Feed matching:

Baby fish is a carnivorous animal, which is rich in natural feed resources, mainly fish, shrimp, frog, shellfish, Loach, chicken and duck embryos, mutton, beef, rabbit meat, earthworms and so on. The feed coefficient of adults fed with natural diet is 3.5-6.3. The feed coefficient of adults fed with artificial formula feed is 2.8 to 3.6, and the bait varieties can be decided according to the local feed resources.

(2) Feed feeding

Because the individuals of baby fish are different, there are seasonal changes in food intake and feeding frequency. in general, it can be adjusted according to individual size, and each feeding amount is equal to 2.4% of the body weight of baby fish. For example, it is fed once every 3-5 days in spring, 2-3 days in summer, 2-5 days in autumn and 4-7 days in winter, and the water temperature should be controlled during feeding. Generally, when the food intake is more than 12 ℃, the food intake is the largest and the growth is the fastest at 18-23 ℃. When the water temperature rises above 26 ℃, the food intake will decrease, and the feed can be reduced at that time.

(3) feeding skills:

When feeding the baby fish, it is generally chosen to be carried out in the fixed food field on both sides of the pond ventilation to facilitate the observation of the growth, activity and feeding situation of the baby fish, and to adjust the feeding amount.

(4) Feed management:

① do a good job of baby fish feeding log, establish a detailed feeding growth file, each weighing once, in order to timely adjust the feeding amount and grasp the weight gain of baby fish.

② regulates water temperature and room temperature. Baby fish can not bear high temperature, so in summer and autumn, be sure to adjust the water and room temperature below 25 ℃.

③ aquaculture ponds should do a good job of sewage discharge and water change every day, observe the growth of baby fish frequently and pay attention to guard against theft and prevent baby fish from escaping.

④ bait can be fed regularly at five o'clock in the afternoon, and the leftover bait will be picked out the next day to prevent the residual bait from deteriorating and polluting the water quality.

(5) Note for feeding:

① timing: timing is according to the biological habits of baby fish feeding characteristics at night, but also according to the season, water temperature, water quality status appropriate advance or push back. General casting time: 10:00 in summer and 8 p.m. In winter.

② quantity: according to different factors such as feeding, digestion, individual growth, body size, water temperature, water quality and so on, appropriate amount of words are given.

③ positioning: positioning to develop the feeding habit of dollfish, which can promote the concentrated feeding of dollfish. Group feeding can not only improve the appetite and food intake of dollfish, but also reduce the dispersion of lexical materials and improve the efficiency of lexical materials.

④ quality: as most of the configured feed contains water, it should be kept at a low temperature, dry and unsuitable for dampness. In addition, in order to improve the utilization rate of compound feed protein, grease can be added appropriately when preparing feed (add fish oil, vegetable oil, etc.). The amount of oil added varies with the water temperature. Generally, oil can not be added when the water temperature is below 12 ℃. When the water temperature is 14-17 ℃, the oil addition is 5%-6%. When the water temperature is 18-23 ℃, fish oil and corn oil are added each of 5%. The natural bait is required to be fresh and clean. If it goes bad, you must not add words.
