Method for cultivate map fish
1, stocking density
Map fish consumes a lot of oxygen, so it is appropriate to put it in a diluted state in an aquarium. 120x50x50cm aquarium, 6cm can raise about 40 map fish, 10cm can raise 20 fish and 18cm can raise 4 fish. 6, when the body length is more than 25cm, 2 can be stocked.
2. Water temperature
The suitable water temperature for map fish is 22? 28℃, the most suitable water temperature is 24? At 26℃, when the water temperature is lower than 18℃, the map fish will die, and when it is higher than 30℃, the map fish will not live well or even die.
3. Water quality
Although the requirements for the water quality of map fish are not very strict, the water quality is fresh, which greatly promotes the growth of fish. Every night, the water changing capacity of the aquarium reaches 1/2? 3/4, a month later, the map fish with a body length of 2cm can grow to about 7cm. Every time fresh water is added, it can stimulate the metabolism of fish and enhance appetite, so the growth rate is accelerated. Generally, during the feeding process, the water exchange rate is 1/2 every day, and the water is completely changed once a week. At the same time, the map fish was soaked in 0.5% aqueous solution of Suda for 10 minute, which promoted metabolism, increased appetite and accelerated growth.
4. food
Map fish like to eat live animal food, and generally feed on earthworms, Daphnia and dragonflies in the juvenile stage; Adult stage is generally eat small fish, shrimp, loach, etc. Eat 2 ~ 3 times a day, preferably within half an hour a day.
5. Lighting equipment
Map fish need to receive proper light every day. In a day, you should receive at least 2 hours of light, so as to ensure the normal life of the map fish and make the body color of the map fish more gorgeous. At the same time, the water quality is reformed through illumination, so that the fed water is not easy to fail.
The cultivation of map fish is not suitable.
1, it is advisable to prevent diseases first and seek medical advice after avoiding diseases.
It is difficult to observe the symptoms of fish at the beginning of the disease. When it is cured, sick fish often eat less or not, which brings difficulties to medication.
2, appropriate regular prevention, to avoid civil air defense.
The onset of fish has a certain periodicity. For example, when the water temperature is low in early spring and late autumn, fish are prone to grow water mold, and grass carp and herring are prone to aging in early summer and Mid-Autumn Festival. Three diseases? The high water temperature period in summer is the high incidence season of fulminant fish diseases. According to this rule, fish diseases can be prevented in advance.
3. Comprehensive prevention should be taken to avoid single drug.
Fish disease is the result of comprehensive factors, so comprehensive measures must be taken to prevent fish disease, inhibit pathogens, improve water environment and improve fish disease resistance. Including thorough cleaning of ponds, fish disinfection, regular water injection and application of quicklime, scientific fertilization and feeding, regular internal and external treatment, etc.
4, appropriate low temperature disinfection, avoid high temperature medicine bath.
Medicinal bath is an important method to prevent and treat fish diseases. Generally, when stocking fish in low temperature season, it is carried out in wooden barrels or pots. In summer, this method is very harmful because the water temperature is very high.
5, appropriate rotation of medication, to avoid a single drug.
If only one drug is used to prevent and treat diseases in water, all kinds of pathogenic bacteria and parasites in fish will develop drug resistance and reduce the effect of drug use. Therefore, drug rotation should be actively advocated, but acidic drugs and alkaline drugs should not be mixed.
6. Take medicine regularly and avoid taking medicine at any time.
The use effect of fish medicine, especially the overflow medicine in the whole pool, is closely related to water mixing, dissolved oxygen and illumination. High water temperature, rich dissolved oxygen and strong illumination can speed up the effective speed of drugs, improve the curative effect and reduce the side effects of drugs. Therefore, the prevention and treatment of drugs should be carried out in a sunny afternoon.
7, appropriate amount, avoid adding.
The dosage of various fish medicines is determined by many experiments, which can effectively prevent and treat fish diseases with little side effects. If used in excess, it will not only increase the cost, but also cause drug damage.
8. Non-metallic containers should be selected for storing and dissolving drugs, and metal containers should not be used.
Fish drugs are mostly synthetic drugs, which are unstable in chemical properties and easy to react with metals, and their components and properties change. Therefore, containers made of nonmetallic materials such as ceramics, wood and plastics should be used to store and dissolve fish medicine.
Life habits of map fish
environment
Map fish live in tropical areas, and the suitable water temperature is 22-26℃.
Water quality requirements: pH: 7.0-7.5.
The hardness of aquaculture water is 7- 10, the pH is 7-8, and the water temperature is 25-26 degrees Celsius.
strange hobby
Its wild fish are very fierce, sometimes killing each other or eating their own small fish. But if it stays with other kinds of fish for a long time, it will protect it.
Map fish are huge, slow-moving, fierce and greedy. They swallow almost any acceptable bait, but their favorite food is fresh small fish and shrimp. When eating, even a small fish that has not been swallowed in its mouth chases and preys on others, which shows its greed. So don't mix with other smaller fish, so as not to become their snacks! It can live normally in weak acid, neutral and alkaline water. Atlas fish is an egg-laying fish. 18 months old reaches maturity and can reproduce many times a year, mostly in summer and autumn, so it is not difficult to reproduce. When they are sexually mature, they will fall in love and find a mate as long as they put the naturally matched parent fish into the breeding box. The feeding box should also be larger, and some smooth stones or porcelain plates should be placed in the feeding box as oviposition accessories in advance.
According to relevant information, there was a record that the map fish lived in the aquarium for 13 years. At the same time, they are also the most emotional fish in tropical fish, and they can even recognize their owners who have kept them for a long time. When strangers are watching, they will do their own things as if nothing had happened. When their owners approach the aquarium, they will swim over immediately, roll their eyes and wag their tails to welcome them. They will also accept their master's touch without surprise. Well-trained map fish even jump out of the fish tank to accept the bait from their owners. In a word, map fish is a very interesting ornamental fish.
After artificial improvement, map fish have many similar species, and their body color and shape have become more colorful. Recently, a kind of albino fish with long tail and red eye appeared in the aquarium market. What's its name? Comet Jasper Pig? .
