I have 15 boats, which belong to Suda fish, that is, the waters where the ocean meets the river. Therefore, the water for raising ships must be salted, with crude salt or sea salt. Edible salt is unacceptable. Rubber boats are very sensitive to bacteria and water quality. In order to reduce the threat of bacteria to it, the red worm should be disinfected when feeding. Can be disinfected with high concentration yellow powder. Moreover, coral sand should be used as bottom sand for water supply to improve PH value. I summed up some questions about submarines myself. Look at this. I want to buy some, but I have to consider the following questions: First, is the submarine poisonous? If it is poisonous, will the water that raises it also become poisonous water? When changing water, it is inevitable to encounter the water that raises it, so it will not be poisoned.
Second: Some people say that submarines eat meat, frozen blood pets and dried blood worms. Why not talk about fresh blood worms? Can you eat fresh blood-activating worms after all? (How many blood worms are fed at a time? )
Third: What is the PH value of water suitable for raising submarines?
Fourth: What is the suitable water temperature for raising submarines? (Do you need constant temperature? )
Fifth: If you want to raise more than six, but not more than ten, is it enough to use a generous bathtub of 1.2 meters?
Sixth: does the submarine like to bask in the sun?
Seventh: How much coral sand do you need to put? Too much will affect whose PH value is too high and lead to submarine death?
Eighth: keep some water snails, snails and live aquatic plants in the bathtub to form an ecosystem. Will it eat them all?
Ninth: How much crude salt (crude salt) should be added after the tap water is dried for 2 or 3 days? (1.2m fish tank)
Tenth: Does the submarine depend on oxygen demand? Do we have to add oxygen 24 hours *7 hours?
Eleventh: What do you mean you can't get along? Can't you keep it with other kinds of fish? Or can't submarines be placed in more than one Tanqueray?
Twelfth: The living environment is crowded, that is to say, how many submarines does a Tanqueray have? 1.2m fish tank.
Solution:
Adult fish length 10~ 15cm. The body is rectangular, with a thick and round head and a flat tail handle. The body surface is smooth and scale-free. Without ventral fins, swimming only depends on pectoral fins, short dorsal fins and gluteal fins, so swimming speed is not fast. Body color will change with mood or health. The abdomen is white, the back is golden, the back is dotted with irregular black spots, and there is a particularly bright gold on the forehead. The fins are translucent, and individual caudal fins have regular light black spots or curved black lines.
First: non-toxic, when in danger, it will swallow water into the special cavity of the stomach and abdomen, making itself swell into a ball, exposing short thorns, so that the enemy can't swallow it at once. Will use the friction or vibration of teeth or pharyngeal teeth to make a sound.
Second: Long-term feeding is not recommended, because live blood worms sometimes carry germs. It is advisable to eat all the bait within 5 minutes each time.
Third: weak acidic water with moderate PH value.
Fourth: between 24 and 28 degrees.
Fifth: it is completely enough.
Sixth: the light should not be too strong, nor should it be irradiated for a long time, otherwise algae will grow easily. Lighting for about 4-6 hours a day is enough.
Seventh: it is advisable to stabilize the water quality with weak alkalinity, and coral sand and shell sand can be used. The particle size is preferably 2-3mm, which will not block excreta on the one hand, and is also convenient to clean with a sand washer on the other. The bottom sand should not be too thick, just 1-3cm.
Eighth: Shrimp and snail are the main food sources for boats in nature. Please don't put shrimps and snails in the tank unless they are used to feed the boat.
Ninth: the salt used for soda (semi-seawater) should be natural seawater salt, and ordinary iodized salt should not be used.
Tenth: dispensable, depending on personal needs. No more than 1.2m cylinders.
Eleventh: The dinghy is aggressive, and it is likely to attack other fish. To avoid tragedy, don't mix rubber boats with other fish. Many people complained that the boat was a cruel killer with a baby face, and even sentenced it to death immediately after discovering that it had committed a crime. In fact, this is the bitter fruit caused by the ignorance and wrong polyculture of the owners.
Twelfth: 1.2m * 0.6m tank is suitable for 8- 10.
Feeding methods and precautions:
If you want to raise any kind of fish well, before setting up a fish tank, you must first understand the environment, water quality and food source of the natural habitat of the target species, and simulate this ecological environment as much as possible in the fish tank.
Rubber dinghy is a small puffer fish that lives in tropical steam waters.
The so-called "steam water area" refers to the estuary of the river, which is the dividing line between freshwater fish and marine fish. Every day, because of the inflow of river water, the tide of seawater and the proportion of water in steam water area are constantly changing. proportion ......

How to breed nontoxic puffer fish?
Cultivation techniques of nontoxic puffer fish;
I. Daily management
1. Feed feeding
After the puffer fish enters the pond, the water temperature is 15 ~ 17℃, so it should be fed regularly. At the beginning of entering the pond, the puffer fish are lured to feed first, so that the puffer fish form the habit of feeding at fixed points. Feed wet pellet bait, now. The daily feeding amount is 0.5% ~ 3% of the weight of puffer fish, and it is fed 1 ~ 2 times a day. When the water temperature is lower than 65438 02℃, the food intake of puffer fish is obviously reduced. When the water temperature is 10℃, the puffer fish basically stops feeding and needs to stop eating. Try to let the puffer fish eat well when feeding, and remove the residual bait in time after feeding to prevent the water quality from deteriorating. A small amount of vitamins e and c can be added to the bait to prevent it from suffering from nutritional diseases.
2. Water quality management
When overwintering in high density, it is necessary to maintain good water quality, and it is best to use sterilized water. The water temperature is suitable, the puffer fish can still be eaten and needs feeding. Generally, the pond should be completely changed and constantly inflated. When the water temperature is low, the puffer fish stops feeding, and the water exchange rate can be reduced to 10% ~ 30% of the pool water, with intermittent aeration for 30 minutes each time and gas stoppage for 30 minutes. Strengthen aeration every night to prevent fish from dying due to lack of oxygen in the air. The feces, residual bait, water meter film and dirt in the pool should be cleaned up in time to prevent water pollution.
3. Prevention and treatment of fish diseases
The puffer fish overwinters indoors with high density, which is easy to get sick. Before the fry enter the pond, they should take a medicinal bath to remove parasites on the body surface and prevent the injured individuals from being infected with bacteria or water mold. The overwintering period is mainly prevention, and the body surface is disinfected with antibiotics every 10 ~ 15 days. You can also continuously feed bait containing antibiotics for 3 days every 15 ~ 20 days for disinfection in vivo. Ill fish should be fished out in time and treated in isolation to prevent the spread of fish diseases.
4. Water temperature control
During the wintering of puffer fish, we should always pay attention to the change of water temperature and weather forecast, and make full preparations before the cold wave comes to ensure that the heating equipment can operate in time. When the indoor water temperature is lower than 12℃, measures should be taken to increase the water temperature to about 14℃ and keep it constant.
5. Invert the pool and change the water
Changing water can reduce the number of metabolic wastes and bacteria in water and improve the water environment. Inverting the pond can thoroughly disinfect the fish pond regularly, kill harmful organisms and parasites in the pond, improve the water environment of the pond, reduce the occurrence of fish diseases and improve the survival rate of overwintering. Generally, once a month 1 time, the wintering pool is thoroughly disinfected. It is best to use the adjacent pond to reverse the pond, which can reduce the labor intensity. Siphon the upper pool water into the disinfection pool. Generally, sewage is sucked 1 ~ 2 times a day to suck pollutants such as feces and residual bait out of the pool to reduce water pollution. At the same time, change or replenish water every week 1 time, and the water change amount is 1/5 ~ 1/4 of the pool water. [3]
Second, reduce costs.
1. Reduce heat energy consumption
Waste heat, power plant cooling water, geothermal water and other resources can be used to reduce the heat input of aquaculture units; Strengthen heat preservation measures to reduce heat dissipation in the wintering pool, and control the wintering water temperature at about 65438 04℃.
2. Reduce power consumption
In winter, the dissolved oxygen in the pool is 6 mg per liter, and puffer fish can still eat and swim normally when the dissolved oxygen is 3 mg per liter, and there is no sign of hypoxia. Therefore, dissolved oxygen can be monitored and determined, and the time ratio between inflation and gas stop can be adjusted to save electricity. When the puffer fish overwinters indoors, it can be ventilated intermittently 1 hour and stopped for 3 hours.
3. Reduce the amount of seawater and brine.
The suitable salt content of puffer fish is below 20. After fish adapt to the overwintering environment, the salinity can be reduced by about 5 per time. Combined with changing water, fresh water can be gradually used, which can reduce the consumption of seawater and brine and prolong the water changing period.
4. Improve the survival rate
During the wintering period, 1 time of drug prevention and treatment is carried out every month to strengthen the prevention and treatment of fish diseases, and the sick fish are taken out in time for isolation treatment. From the aspects of temperature, salinity, water quality, dissolved oxygen, etc., create an environment that adapts to the wintering of puffer fish and reduce its illness or death.
Indoor wintering of puffer fish is not limited by geographical and climatic conditions, and it is a suitable wintering method for both north and south. Where conditions permit, the cooling water from power plants and the waste heat from factories, caves and tunnels can be used to overwinter puffer fish, which can achieve large-scale overwintering.
Three, pond seedling technology
1, small-scale fish farming
(A) pond selection
The pond requires sufficient water source, pollution-free water quality and small change of water temperature throughout the year. If brackish water or fresh water is used for aquaculture, the pond should be built in a place with convenient water lifting, short route and low lift. The bottom of the pool is basically water-tight and water-tight, making it easier to build dikes and open floodgates. In addition, convenient transportation and power supply are required, and there are no tall buildings around the pond, so it is not easy to be impacted by storms or floods.
(2) Cleaning and disinfection of ponds
Drain the water in the pond in winter or in slack season, dig out the mud at the bottom of the pond, and then naturally expose it. Before the fingerlings enter the pond, the pond should be cleaned with quicklime and bleaching powder for disinfection. Amount of quicklime per mu ......
How to raise puffer fish well?
Green puffer fish (also called golden doll) is the hottest dolphin ornamental fish in tropical ornamental fish. It belongs to the same species as puffer fish and is also the cutest ornamental fish. Its chubby body is green with black spots on it, especially its fins. Compared with its body, it is quite small and always swings, which is really cute. At first glance, many people unconsciously reach for their wallets and want to take them home, but problems follow. ....
Let's talk about the choice first: there are two key conditions for choosing it. First, look at its belly. The belly of an intact golden doll should be pure white. His white belly is a mirror reflecting his health. Often the golden dolls in bad condition have gray bellies, and some are completely black. This kind of fish must not be eaten. Secondly, because the golden doll belongs to the dolphin family, its appearance is completely different from that of ordinary fish. Its body is olive-shaped and its shape is relatively "fat". At this time, you still have to look at its belly. If there are irregular protrusions, it means that its gastrointestinal function is not very good, and this fish can't be used. One more thing, when picking fish, you often can't see a golden doll with intact fins, which can be completely ignored, because there is usually a little friction between them, and small casualties are inevitable.
Let's talk about reproduction first: the golden doll belongs to the dolphin family. It has the complete characteristics of ferocity and cruelty of the dolphin family. Although it looks really cute, if you kindly want to mix it with other small fish, you are all wet. The next morning, you will be surprised to find that there is nothing in your fish tank except a dead golden doll! So don't mix gold dolls. It has an amazing appetite and will take the initiative to attack other fish. This is the characteristic of dolphin fish! Once I fed it. It was cruel. It bit off a piece of skin from my hand. Can only be raised singly, and the density cannot be too large; There are more aquatic plants in the tank, and the filtered water flow must be slow. It doesn't like strong water flow, so don't add activated carbon to the filtration system! Golden dolls like weak alkaline water, and activated carbon will only lower the PH value; Always observe the color of his belly, which is the most intuitive way to check his health.
In fact, it is very simple to raise a golden doll, just do as I said above, but it is often said that it is not easy to raise it. I think the problem may lie in the selection, because the general fishmongers don't put them in glass jars for people to choose from, but usually put them in plastic white pots, so that we can only see the color of his back, but not the color of his belly, so it is easy to choose the golden doll with poor conditions, and all the selection must be done. Be sure to see if its belly is white ~
Is puffer fish a freshwater fish or a marine fish?
Most of them live in seawater, and a few live in fresh water (such as dark striped oriental dolphins). The puffer fish meat is delicious, but the viscera, blood and skin are highly toxic, and there is almost no solution after poisoning. All toxic parts must be removed before eating. The sale of this thing seems to be forbidden (even if it is bought and sold privately).
How to raise a little puffer fish? You bought it in the market. Is it freshwater fish or saltwater fish? The seller said salt, didn't he?
Look at what puffer fish you bought. All puffer fish are from sea water. But some puffer fish live at the junction of seawater and fresh water, so some puffer fish can survive in fresh water for a short period of time, but after a long time, they will lose their appetite, get sick and die.
If you want to feed dolphins and fish, you must mix seawater with sea salt in proportion.
Can puffer fish be kept in cold water?
The puffer fish is a kind of soda fish, which lives at the junction of fresh water and seawater. So we need to add some sea salt. Chocolate dolls in puffer fish can be raised in fresh water, but submarines can't. The water depth is not required, not too shallow. The requirement for water temperature is not high.
What water quality is needed to raise puffer fish?
I will tell you in two parts, including water quality and other knowledge. I wish you success:
(1) As a pet:
Principle 1: Minimize their stress. Stress will destroy their immune system and make them easy to get sick. Establishing a comfortable family and living environment for them is a good way to relieve stress. You might as well arrange something for them to hide in the jar. Aquatic plants with broad leaves, caves and heavy trees are a good choice. These little guys will be more active in the evening and at night. During the day, they usually like to hide and rest. In addition, constant water temperature and PH value are very important for them, because they are actually very sensitive. Besides, they like the house with bottom sand. Of course, filtration and water flow are also necessary, but the water flow is slow, maybe they like quiet. It is also important to choose the right partner for them. We can choose suitable playmates for them by considering factors such as body shape and habits. Of course, there may be unexpected situations. For example, little guys often do them a little harm or simply eat them as snacks. If his playmate is fierce, then the little guy may bear it for a while, and if he can't bear it, he will fight with his opponent, who is either dead or seriously injured. After all, the little guy is not easy to mess with. There is something called tetrodotoxin in his body.
Principle 2: Give the kids the right food. The little ones are carnivorous. They don't eat plants, and rarely eat all kinds of artificial feed. The above food can't provide the nutrition that the little ones need to grow up. Usually, frozen or fresh blood worms, earthworms, shrimps, shellfish, crabs, squid and snails are all their favorite foods. Be careful not to overfeed, which may lead to constipation. They often pray for food, even if they are full. Because they love to eat so much, if their bellies get very big, it means they eat too much. You can feed them 1-2 times a day. Usually, their stomachs will collapse a few hours after feeding. If their stomachs are always bulging, then your little guy may be constipated.
Principle 3: always check the physical condition of the little guy. As a daily habit, carefully check the whole body of the little guy every day to see if there is any possibility of external diseases, bites and injuries caused by parasites, bacteria and fungi. By the way, observe their activities and see if their actions are abnormal. One of the advantages of this routine inspection is that the little guys will know you soon. When you come to the tank, they will hover and swim up and down in front of you. Pay attention to several bad signs:
1. He has a bad appetite. Actually, the little guy is very greedy. If he is found to have a bad appetite or picky eaters, there must be something wrong.
2. Press the line. If you find dark gray lines between the back and abdomen of the little guy, these lines can extend from the mouth to the tail, which is also an unwanted sign.
3. For the type of white belly, if the little guy's belly turns black and the color deepens, you should also pay attention.
4. Under normal circumstances, the color of the little guy's back will change with the time of the day and other factors, but if the color of his back gradually darkens, it will not become a normal body color for a long time, which is also one of the danger signals.
If problems are found, carefully check the living environment of the little guy (salt temperature filtering PH, ammonia and nitrite concentration). If there is no problem in the environment, make sure that there are no other * * * (some big fish) in the little guy's tank to make him feel scared, and there are enough hiding places in the tank for him to rest. If all the above conditions are normal, it is necessary to carefully check his body for physical damage.
(2) Aquaculture:
1. If you have a green puffer fish (yellow-green body, round black spots and white belly, the most common species on the market), then you need soda water, that is, salty fresh water between fresh water and seawater, and the proportion should be controlled between 1.05438+05- 1.020. Just choose ordinary tap water and add salt after it bursts.
2. Generally speaking, a white-bellied puffer fish is a healthy puffer fish as long as it swims lively and looks normal (fishmongers often have fin damage, so the requirements are not high). A gloomy stomach or dark spots is probably unhealthy or in a bad mood, but this is basically the case in fish shops.
3, puffer fish is not easy to raise, because the natural environment in which it lives is difficult to simulate artificially. If this kind of soda fish is not strong, it is estimated that it will not live long in artificial environment. As for using cups ... I'm telling you, if ......
