Family rearing method of Lanshou
Choose goldfish
Choose fish with strong bodies and bright colors.
If you choose any kind of goldfish, you should choose the one with broad and firm body, complete chest, abdomen and caudal fin, and wide tail. Fish without dorsal fin should have a smooth back and no incomplete dorsal fin or nodule. The colors of fish should be red and delicate, white and pure white, blue and blue, black and black, and the colors of flowers should be harmonious and the patterns should be meticulous. Only those with blue can be called Wuhua. Some fish are half red and half black, or those whose bodies are red and the edges of their fins are black. They look beautiful at the moment, but in fact they will soon become all red, so be prescient.
When choosing fish, choose those that are unique in characteristics, body shape or color and observe them.
Choose healthy and disease-free fish.
Generally speaking, swimming in the pool (basin) is active, gregarious and plump. The pectoral fins and ventral fins are open and often paddle, and there are no white spots and white fluff-like mucus on the body. The tail and scales are congested and festered, and they do not often float on the water, nor do they lie on their side, stand upside down or sink to the bottom. Black and thick shit is healthy fish, and fish are looking for food.
Choose fish with obvious characteristics
All kinds of fish have the characteristics of this species: such as longevity head, lion head, crane top red, goose head red and other species, which are famous for their sarcoma on their heads. Therefore, we should choose the most developed and widest sarcoma on the gill cover of their heads. In addition, fish with red sarcoma, such as crane top red and goose head red, are all top grades with square red tops (the top of the head is darker when young). When choosing pearl oyster fish, we should pay attention to two kinds: big tail and small tail, and the big tail is better. But no matter the big tail or the small tail, we should choose the small head with thick beads and scales, and arrange them neatly until the back, but the scales can't stand up, otherwise most of them are scales. Abdominal distension is thick and round with smooth tail. This feature is purebred. Blisters or dzi beads are named according to the characteristics of the eyes, so choose round and symmetrical blisters and soft and transparent blisters. When choosing dzi beads, choose people with big eyes that protrude like chess pieces.
Raise water before raising fish.
How to be in the family? Raise? It is very important to have a jar of clear and nontoxic good water. Family fish farming is different from fish farming. The water space is narrow, and the water quality is required to be clear and transparent, which is convenient for viewing goldfish. Fish farms raise fish to make goldfish grow quickly. There are professional fish working hours to monitor the water quality, and the water body is wide and suitable for goldfish growth. Family goldfish has its own advantages. For example, the water temperature, because family fish farming is generally indoors, is not affected by wind and rain. Moreover, raising fish at home is convenient for water quality observation and drug control because of the small amount of water. Raising water for domestic goldfish is mainly related to the following five factors.
1. filtration system: Due to the high density of fish farming in families, it is difficult to remove impurities and wastes from water only by the decomposition of water itself. Establishing a good filtration system can effectively maintain water quality. A good filtration system can integrate chemical, biological and physical filtration methods. Chemical filtration relies on special drugs to condense tiny suspended impurities in water, so as to precipitate them or physically filter them out. Bio-filtration is to use beneficial biological flora to decompose waste in water and decompose harmful substances into harmless substances. Physical filtration is to adsorb and filter out impurity particles through the tiny pores of the filter material. According to the characteristics of goldfish and family fish farming conditions, the following methods can be used to establish a filtration system. According to the size of the aquarium, an external filter is configured, which can be overhead or a filter bucket. The flow of water can be found in the description of the pump. Generally speaking, it is advisable to circulate water about 7 times per hour. For example, the volume of an aquarium with a length of 80, a width of 40 and a height of 40 is 1.28 liters, and the flow rate of the filter pump is 900 liters/hour. For larger aquariums, in order to prevent the water from flowing too fast, it is suggested to install a built-in filter at the entrance and an elbow at the exit to reduce the impact of the water on goldfish. Biochemical sponge and activated carbon are put in the filter box (barrel) and replaced according to the degree of water pollution. But too frequent replacement is not suitable for the establishment of beneficial biological flora. Generally 1 month can be replaced once.
2. Biodecomposition: In the natural environment, a large number of beneficial bacteria are attached to the places where rivers flow, and they can decompose metabolites and foreign pollutants produced by organisms in water. Keep water clean and harmless. Establishing beneficial flora in the aquarium can keep the water quality for a long time without changing water frequently. Adding nitrifying bacteria to the aquarium is a shortcut to establish a biological decomposition system. Nitrifying bacteria sold in the market are mainly divided into two categories, active nitrifying bacteria and artificial nitrifying bacteria. Active nitrifying bacteria take living flora as the main substance. Artificial nitrifying bacteria are substances that promote the growth of nitrifying bacteria in water. Active nitrifying bacteria take effect for a short time, and generally the effect is most obvious when the water temperature is 25-30 degrees within 2-5 days. But the storage time is short, usually less than 12 months. Artificial nitrifying bacteria have a long storage time, generally about 2 years, because they do not contain active strains. But it takes a long time to take effect. Before the establishment of biological system, water quality clarifiers can be used in combination.
3. Fish density: No matter how big the aquarium is, the number of goldfish cultured is limited. Goldfish are lively and active, and can eat and pull. The water quality of small tropical fish is difficult to maintain. Reasonable breeding density is very important for beginners. Usually 1 year-old goldfish will take up 10 liter of water. That is, an aquarium with a length of 80, a width of 40 and a height of 40 has a volume of 128 liters and can support 1 fish 12. No matter how high the density is, it is difficult to maintain water quality for a long time. In addition, different goldfish species have different requirements for breeding density, and rare species such as pearls, butterfly tails and blisters have smaller breeding density.
4, feed selection: goldfish feed also has a lot to do with maintaining water quality. Goldfish are omnivores. Food covers a wide range. Mainly includes: Daphnia, nematodes, hemoglobin, pellet feed, powder feed, sheet feed, etc. Live Daphnia is the best choice. Not only in food intake, Daphnia can also suck organic suspended solids in water. Moreover, the metabolites produced by goldfish are not easily dispersed. Nematodes, red blood worms and powdered feed may be attached to the sand bed or suspended in water, which is not conducive to the cleaning of water quality. High-quality synthetic feed will contain yeast, which can quickly decompose the metabolites of goldfish and help maintain water quality. Inferior synthetic feed not only has no nutrition, but also contains artificial pigments, which will discolor water. In addition, it is best not to use edible fish feed, such as crucian carp feed for goldfish, which will also pollute the water quality. When feeding, the filter system should be closed to avoid being sucked into the filter box, which will not only cause waste, but also mold and produce toxic substances in the filter box.
5. Fish culture environment: lighting, scenery, etc. It also has a certain relationship to maintain the water quality of the aquarium. Excessive light will cause a lot of algae in the water. Proper curtain covering and regular cleaning will be effective. Proper placement of sand bed at the bottom of aquarium will also be beneficial to water cleaning. It can not only adsorb impurities, but also provide a hotbed for nitrobacteria. Generally, the thickness is about 4 cm, and the particles are about 4 mm. The sand bed is too thin to be adsorbed. Too thick sand bed will make the bottom sand bed lack oxygen and cause biological corruption. If the particles are too large, the feed will sink into the gap, which is not conducive to goldfish eating; Too small is not conducive to the oxygen transfer between water flow and particles, and is also not conducive to the growth of nitrifying bacteria.
Pay attention to the above points, and you will definitely have a clear water tank to create an ideal living space for your beloved fish.
Lanshou feeding method
In the process of feeding blue lean, the choice of blue lean feed is very important. Lanshou golden fish should choose and make a reasonable and nutritious recipe. Although Lanshou is an omnivorous fish after long-term domestication, improvement and cultivation, its feed selection is the same as goldfish.
Whether the feed selection is reasonable and the feeding is correct will directly affect the growth, color depth and bright degree of Lanshou goldfish. It also affects the cultivation of green water to some extent. Lanshou's feed must be rich in protein, fat, carbohydrates, vitamins, a small amount of inorganic salts and trace elements. For example, if you eat red worms every day, your longevity will grow fast and your head tumor will be developed, because red worms contain a lot of balanced nutrients.
Lanshou feed can be divided into plant feed, animal feed and artificial feed. Personally, I think animal bait is better. This kind of goldfish has a lot of food and can be eaten as fish. Dinner? This kind of food can provide goldfish with all kinds of nutrients. But when choosing this kind of food, we must pay attention to ensure the freshness of the food, and never feed the goldfish with food that has been stored for too long or died for a long time. Water quality and the health of goldfish will be affected. Therefore, generally, the animal bait we feed the golden fish needs to be disinfected. Generally, when selecting this kind of bait, you also need to pay attention to the cleanliness of the bait.
1, animal feed, which is the favorite of Lanshou goldfish and the most balanced feed, and is the main staple food. Animal feed includes fish worms (red worms, water fleas), cyclops, paramecium, water worms, bread worms, shrimp and so on.
2, plant feed, Lanshou's feed is of course the most ideal animal feed, but in the absence of animal feed for various reasons, plant feed can become an emergency or life-sustaining auxiliary feed. Plant feed includes: duckweed, duckweed, Ceratophyllum, chrysanthemum grass, etc.
3. The goldfish feed purchased in the market has simple operation and balanced nutrition.
Lanshou feed should be disinfected in advance, and the living body can be soaked in salt water or low-concentration potassium permanganate. For example, radish in plant feed can be soaked in low concentration potassium permanganate first, and then fed to goldfish.
The origin of blue and thin varieties
Lanshou was cultivated by the tiger's head in China. But the appearance and aesthetics are quite different from China's tiger head. Japanese books? Egg worm? (that is, China? Eggs grow goldfish? ), and then read? Blue chip? Did you do it? Fish orchid, fish live long? Yes, it's commonly called Lanshou in China.
Lanshou, which is widely sold in China, was re-bred by Lanshou in Japan? Guo shou? . Do people live in Fuzhou? Fushou? The most famous, are they made in Japan or made in China? Rishou? Is it made in Thailand or made in China? Taishou? Together, it has become the three mainstream varieties of Lanshou.
Among them, birthday pays attention to square head and tail, national life pays attention to exaggerated head and obese body, and Taishou pays attention to back and tail.
