Question 1: Can otters be raised? Yes, many people in China are breeding otters. They are important fur animals! If the ones you catch alive are wild, you can keep them if you have space, but you have to feed them fish and shrimp all year round! And there is a pool! In addition, the smell of this thing's feces is also quite strong!
Question 2: How to breed otters? Raising otters does not violate national laws. Wild otters are protected animals
Farmed ones are not.
Otters are precious fur-bearing animals that live in many habitats. In lakes, ponds, rivers, and fresh water with fewer aquatic plants and more fish. Otters are good swimmers, diving into the water at night and generally living alone. Its hearing and vision are very keen, and it often hunts fish, frogs, rats, and crustacean aquatic animals at night. It matures after one year and usually molts once a year. It usually breeds and gives birth to cubs in spring and summer, with 2-5 otters being born per litter. The baby otters will be able to live independently after 3 months of suckling.
Pen construction To raise otters, you need to build a breeding cabin with an area of ??2.8×3.5 meters and a pool of 3×1 meters. There are wooden birthing boxes (1×0.6×0.8 meters) indoors. Leave a small hole and line the box with hay. There is a cement floor with a barbed wire fence (3 meters high) outside the small room.
Feeding and management Otter cubs can be weaned 40-50 days after birth, but after weaning they must be captured and raised in another pond, with a stocking density of 8-9 otters per pond. Young otters grow quickly and can reach adult weight in one year. Under artificial breeding conditions, the feed of otters is mainly fresh freshwater miscellaneous fish, and each animal is fed 0.8-1.2 kilograms per day, along with a small amount of animal meat residues, offal, grains, vegetables, etc. In cold weather, the feed standard needs to be increased by 25%. When the temperature is high in summer, you can feed some small fish, loaches, frogs and green feed. Young otters are fed 4 times a day, adults are fed 3 times a day, and they can be fed 2 times a day in winter. Male and female otters should be kept separately during the non-breeding period. During the breeding period, the male otters should be caught in the female otter pond and allowed to mate.
Reproduction technology Otters generally breed in spring and summer. Otters born in the south can breed twice a year. The male and female otters screamed loudly and chased each other, biting each other's coats, feeling very uneasy and losing their appetite. The female otter's vulva is red and swollen, and the duration of vaginal discharge is generally half a month to one month. The place for mating is in the water, and mating occurs mostly at night or early in the morning. Mating lasts for about 5-10 minutes. During mating, the male otter bites the female otter's head and swims or rolls in the water. Each male otter can mate with nine female otters, and no one can get close to them during mating, so as not to affect their reproduction. After the female otter is pregnant, the male and female are raised separately. The appetite decreases in the early stages of pregnancy. After one month of pregnancy, the food intake increases, the abdomen becomes enlarged, and the amount of exercise should be gradually reduced. The gestation period of a female otter after conception is generally 55-57 days. Female otters are ferocious before giving birth and often lie in their nests without coming out. At this time, a litter box should be prepared and some soft hay should be placed in the box in case the female otter needs a nest. The calving period of female otters varies according to different regions. For example, female otters in northern my country usually give birth to cubs in spring and summer after conception, with 2-4 cubs per litter. The cubs can live independently after 3 months of suckling.
Question 3: Can otters be kept as pets at home? My parents are plumbers. When I was a child, I raised a wild one in the mountains. It was coaxed home with a few small fish. It was not afraid of people at all and liked to follow people. It also loved to eat small fish and frogs. It loves to crawl under people's feet and is stepped on many times a day. It's just very fishy, ??especially on rainy days, it's extremely fishy. I kept him during the summer vacation, and when school started, I fed it to my dad’s colleague
Question 4: I have an otter. Can't afford it. what to do? First, in order to protect Minase's life safety and you don't know how to raise it yourself, it is best to send it to the zoo. Second, I think if it is really for Minase's good, you should release it, but the premise is that it is possible because you lack experience in releasing animals. On the contrary, it will put Minase's life in danger, so we should ask relevant professionals to guide the release. Thank you. I think the second option is better!
Question 5: I want to keep an otter as a pet. Because they are protected, they should not be easy to buy. Well, you should have them at a professional breeding farm. However, large-scale breeding is possible, but it seems unrealistic to use them as pets. On the one hand, there is nowhere to buy them, on the other hand, they are protected, and on the other hand, otters have environmental requirements. . . They can survive in the natural environment, but if you raise them, it may be troublesome to set up a simulated natural environment.

Otter breeding
Otter LutralutraLinnaeus Carnivora Carnivora Mustelidae Mustelidae Recognition characteristics Semi-aquatic mammals. The head is flat and broad, with small eyes and ears. There are small round valves in the nostrils and ears, which can be closed during diving to prevent water intrusion. The junction between the base of the nose pad and the fur is "W" shaped. The claws on the limbs are long and sharp, and there are webs between the toes. The body hair is long and shiny, and the tail hair is long and dense. The otter is an amphibian that people have heard of for a long time. It is about the same size as a pug, so it is also called a water ripple. The body of an otter is slender, more than half a meter, much like a cylinder. The head is short and wide and the front end is slightly flat. The limbs are thick but very short. There are webs between the toes, which are suitable for paddling. A special device, the muscular tail is like a rudder tip that can correct the course and can control the swimming direction. The back is brownish black or chestnut brown, shiny, bright and gorgeous. Otters are secretive and like to live on steep banks, riverbank shoals, and in rivers, lakes, creeks and marshes with few aquatic plants and dense forests nearby, where they live a hidden life in caves. People often use "cunning rabbits with three burrows" to describe rabbits' high vigilance against enemies. However, otters also have several residences and often move around, so it is extremely difficult to dig out their nests to catch otters. Otters are skilled in water. Not only can they swim quickly and flexibly, they can also close their nostrils and ears tightly through small round valves, and quietly swim under the water for long distances. It is said that they can swim for 6 to 8 minutes in one breath. , and then put your nostrils out of the water to breathe. It is a powerful hunter in the water. Any fish, frog, or shrimp caught by the otter at a glance will be unable to escape bad luck and will eventually be killed by the otter. An otter spends almost its whole life hunting and living in the water. Only when it is hungry and panicked will it leave the water and go to the shore to forage for mice and birds, or even risk sneaking into a village to steal chickens and ducks. When an otter walks on land, its belly is close to the ground. Due to its short limbs, it is difficult to crawl. It is very laborious and easy to be overtaken by enemies. Its senses are very keen and its memory is very strong. It can accurately land on the shore from where it entered the water, and return to its nest by following the claw marks. Otters breed twice a year. This otter has a gestation period of more than fifty days and gives birth to 1 to 3 cubs at a time. The growth and development of young otters is very slow, and it usually takes more than a month after birth to open their eyes. During the lactation period, female otters take great care of their babies and stay with them almost all day long except when they go out to hunt for food. Two months after birth, the young otters began to practice swimming. The young otters were very excited and excited when they first entered the water, but they were also very frightened. They were afraid of sinking into the water. They clung to the tails of their parents and kept rolling playfully. Otter fur is precious and beautiful, light and tough, with rich undervelve and strong warmth retention. The luxurious fur hats, fur collars, fur sleeves, etc. made from it are all best-sellers in the international market. Otter liver is used as medicine to nourish the liver and relieve coughs. It is mainly used to treat fatigue, night sweats, coughs, night blindness and other diseases, and has certain curative effects. Due to excessive hunting, otters have become rare and rare animals, and are now listed as national level II key protected animals. 1. Construction of the breeding farm The breeding farm consists of a sports ground, a pool, a breeding room and a nest box. The sports ground is open-air, with a cement floor, covering an area of ??10 to 50 square meters, and a height of 2 to 3 meters. The surroundings and top are closed with wire mesh. There is a pool of 2 to 10 square meters in the sports ground,...>>
Question 6: The protection method for otters generally adopts the enclosure method, and the open-air cement ground sports ground covers an area of ??4.5×10.5m. , surrounded by a 3m high barbed wire fence.
There is a 3×6×0.8m swimming pool on the sports ground, which must be equipped with clean water. The sports field is connected to the small breeding room. The area of ??the breeding room is 2.8×3.5m, and there is a 2×1m high pool inside. A wooden farrowing box with a height of 1 × 0.6 × 0.8m is also required indoors. The upper lid of the farrowing box is 1 high with an observation hole, and the inside of the box is padded with hay. Otter cubs can be weaned 40-0 days after they are born, but after weaning they must be captured and raised in another pond, with a stocking density of 8-9 otters per pond. Young otters grow quickly and can reach adult weight in one year. Under artificial breeding conditions, the feed of otters is mainly fresh freshwater miscellaneous fish, 0.8-1.2kg per animal per day, and a small amount of animal meat residues, offal, grains, vegetables, etc. In cold weather, the feed standard needs to be increased by 25%. When the temperature is high in summer, you can feed some small fish, loaches, frogs and green feed. Adult otters are fed three times a day and twice a day in winter. Young otters should be fed 4 times a day, freshwater miscellaneous fish, or rice, minced meat, fish meal, etc. instead of fresh fish. Male and female otters should be kept separately during the non-breeding period. During the breeding period, the male otters should be caught in the female otter pond and allowed to mate. Otters are easy to tame. After taming, the otters can hear people calling them and take food from people's hands. It is reported that the Moscow Zoo in the former Soviet Union once conducted an experiment on raising otters on the ground. The young otters were raised on the ground from an early age and refused to eat when they grew up. Water ingress.
Question 7: Some people keep otters (1) Domestication of otters
Otters are easy to tame. Newly captured wild otters can be kept in a place with low light, good ventilation, and quiet The inner room is domesticated and provided with sufficient drinking water, bathing water and live fish. Minimize human interference. Pay attention to heatstroke prevention and cooling in summer. After a month, when it gradually adapts to the new environment, it will be moved to a cage. The feed is mainly freshwater fish, such as crucian carp, carp, catfish, etc. Each head is fed 0.8-1.2 kg per day. A small amount of livestock, poultry, offal, grains, vegetables, malt, etc. can be fed. A certain amount of frogs and green feed can be fed in summer. Adult otters are fed 2 times a day, and young otters are fed 3 times a day. If rice, minced meat, and fish meal are used instead of fresh fish, otters can eat normally. When the temperature drops to -12°C, the diet should be increased by 25%. According to reports, adult otters require 4604-7533 J of heat energy per day. Otters love to swim. Artificially raised otters need water in summer and snow in winter for their water baths and snow baths. Exercise can increase food intake and make the plush more shiny. The Moscow Zoo in the former Soviet Union conducted experiments on dry-breeding otters. Dry-raised otters refuse to enter the water when they grow up. When it was put into the water, it screamed and struggled to run back to the shore. Dry-raised otters have good fur quality and can reproduce successfully, so artificially raising otters has a broad future. If a newly caught baby otter does not respond to the live fish or lean meat strips it is fed, or has difficulty biting or reacting slowly, it means that it has not been weaned and needs artificial breastfeeding. Milk needs to be diluted appropriately, the milk temperature should be kept at around 35°C, and milk utensils should be boiled and sterilized every day. (2) Management of otters can be done by raising them in pens or cages. The pen house consists of a sports field, a pool, an inner room and a farrowing box. The sports field area is 4.5 meters x 10.5 meters and is 3 meters high. It can be surrounded by welded mesh and has a cement floor. There is a pool inside, with an area of ??1.5 meters × 1.0 meters - 3.0 meters × 6.0 meters and a depth of 0.6 meters × 0.8 meters. In the inner room, a wooden box or brick nest can be set up. Feed indoors in winter. The indoor area is 2.8 meters × 3.5 meters, with a pool of 1.5 meters × 1.0 meters - 2.0 meters × 1.0 meters. The wooden birthing box is 1 meter × 0.6 meters × 0.8 meters, lined with hay. The doors and windows of the cabin must be strong and cannot be chewed through by otters. The sports ground should imitate the natural environment, plant trees and set up stone piles. Pools are always stocked with clear water for swimming. Energy and Nutrient Requirements of Otters
The energy nutritional value of otter feed and diets is expressed in terms of metabolizable energy. The metabolizable energy of the otter's main feed is
determined by a special balance test and based on the difference between the energy content of the feed and that of feces and urine.
The loss of urinary energy in otters is not significant: 25% of the diet is made of sugar beet in winter; 3-3.2% of the diet is made of pasture or grass meal in summer. Metabolizable energy is on average 97.2±0.6% of digestible energy, or 70-80% of total energy, and changes depending on the diet structure.
The amount of metabolizable energy in otter feed and diets is expressed in terms of kilojoules (or megajoules) and kilocalories (250 kilocalories of metabolizable energy is equivalent to 1.05 megajoules).
Balanced and scientific production tests were conducted at the Soviet Research Institute of Fur Breeding and Rabbit Breeding to determine that otters' energy needs depend on their body weight, age and Physiological state, activity in cages of various sizes (with swimming, pool or not), humidity of the surrounding air, type of feeding and pre-feeding feed Modulation, etc.
When raised outdoors, the daily metabolic energy requirement of otters per 1 kilogram of body weight: 250
-200 kcal (1.05-0.84 megajoules) for lactating otters; weaning Young otters are 175-140 kcal (0.73-0.59 megajoules); adult female otters are 110-120 kcal (0.46-0.50 megajoules). When otters were kept in heated
barns without pools and on mesh playgrounds, their energy needs were on average 15% lower than when kept outdoors in cages in the southern regions of the Soviet Union
.
The needs of otters for digestible protein: The metabolic energy per 100 kilocalories of concentrate-juicy feed-type diet in outdoor cages
is 3.6-3.7 grams; When feed-based diets are fed in closed barns, the digestible protein standard is 20-25% higher, which is 4.5 grams of metabolizable energy per 100 kcal. When otters are raised in closed stalls, high protein levels in the diet have been shown to improve the growth of the animals and prevent neutralization in cages lacking water pools. Fatty disease caused by lack of succulent feed.
Otters have a small need for fat: 3-4% of feed dry matter, or metabolizable energy per 100 kcal
