Introduction to Flamingo
Flamingo fish, tropical fish, fish scientific name: Cichlasomacitrinellum, alias Shouxingtou, Shouxing fish, native to Nicaragua, Costa Rica and other places in Central America, belongs to the cichlid family cichlid, with a body length of 20-30cm and a shape similar to a goldfish. The head is large, and there is an obvious round sarcoma on the top of the head, which is different. Body color is pink, juveniles are gray-black, and adults become fiery red, with variable body color, sometimes orange or yellow. The feeding water temperature is 22-28 ℃, and the bait includes fish and insects, water earthworms, small live fish and so on. The breeding water temperature is 27-29°C, the water quality is weakly acidic and soft water, the broodstock is sexually mature for 6-8 months, the male fish has large sarcoma on the top of the head, the body color is bright red like fire, and the female fish body color is lighter, each spawning 200-500 eggs , with smooth rock or marble slabs for nesting.
Breeding environment of flamingo fish
Flamingo fish (Cichlasomacitrinellun), also known as longevity fish, auspicious fish and longevity head, belongs to the cichlid family and is native to South and Central America. It is a tropical fish that integrates ornamental and food. Adult flamingo fish are generally 20cm-25cm in length, strong in physique, and changeable in body color, generally orange-red, white and orange-yellow; the suitable living water temperature is 23℃～28℃, rough temperament, strong territorial awareness, sometimes visible Until the two fish bite each other, so that both sides are injured, so the flamingo fish should not be mixed with small fish. feed.
The breeding facilities used in the breeding and production of broodstock breeding ponds are closed circulating water. The breeding ponds used are cement ponds with an area of 20 square meters and a water depth of 1.2 m. The source water is hot spring water. The water is clear and pollution-free. Before stocking flamingos, the breeding tank should be disinfected with a chlorine dioxide solution with a concentration of 0.5×10E-6, and then refilled with new water.
Selection and breeding of broodstock When selecting broodstock, males are generally required to have a raised forehead and bright body color, the ends of dorsal and anal fins are pointed and the abdomen of females is enlarged, and the ends of dorsal and anal fins are rounded. A cement pond with an area of 20 square meters is generally stocked with 10 to 15 pairs of broodstock flamingos, with a male-to-male ratio of 1:1. Before stocking, the fish were disinfected with povidone-iodine solution with a concentration of 20×10E-6 for 20 to 30 minutes. When broodstock is cultivated, it is generally fed twice a day. The feed is fresh small fish or compound feed. The feed should be fresh, not moldy, and not deteriorated, and the nutrients can meet their developmental needs. Vitamin E can also be added appropriately to promote the development and maturation of broodstock gonads. Regularly discharge sewage and refill 20cm-30cm of new water every day to create a good living environment for broodstock.
Seed reproduction The flamingo fish grows rapidly. After 8 to 10 months of breeding, its gonads are mature and can be reproduced. When 2 adult fish are found alone, and other fish try to get close, these 2 fish show a strong sense of domain and will bite other fish, indicating that these 2 fish have developed love; or if they find a male fish The reproductive process is obviously drooping and slightly slender, while the abdomen of the female fish is swollen, the ovipositor is thick and short, and obviously protrudes out of the body. At this time, it is necessary to take out two male and female broodstock in time, put them in the spawning tank or spawning tank, and put them in the pool. Or put 1 marble or 1 flower pot at the bottom of the tank as an ovary. The spawning pools, spawning tanks and spawning ovaries should be soaked in potassium permanganate solution with a concentration of 20×10E-6 for 30 minutes before use, and then rinsed for use. The breeding water temperature is controlled at 27°C to 28°C. After the male and female broodstock are familiar with the surrounding environment, they will take turns to peck the spawning board with their mouths. The fish then releases semen for fertilization, circle after circle, a process commonly known as “walking the board”. Generally, after 40 to 60 minutes, the spawning is nearing the end. The female fish generally lays 800 to 1000 eggs each time. During this process, the broodstock will continue to swallow the fallen and whitish eggs with their mouths. fish out. It should be noted that the water quality for hatching fertilized eggs is consistent with the water quality requirements of the spawning pond, so as not to affect the hatching rate. During the incubation period, pay close attention to the change of water temperature, absolutely avoid the sudden rise and fall of water temperature, and control the dissolved oxygen content at 5mg/L ~ 6mg/L. After 48 hours to 72 hours of incubation, the larvae burst out of the membrane, and gradually fell off the spawning plate and landed on the bottom of the tank or pond. The newly hatched larvae carry the yolk sac. In the first 2 to 3 days, the larvae rely on the absorption of their own yolk sac to maintain life, and finally float up and swim to the surface. When the larvae swim to the surface one after another, the yolk sac will basically be absorbed. At this time, open bait should be fed in time, such as egg daphnia, which is a common name for several planktonic protozoa, so as to ensure that the larvae can ingest enough and palatable. bait to survive. After another 7 to 10 days, rotifers, cladocerans and copepods can be fed. At this time, according to the stocking density and water quality, the stocking density should be reduced in time to divide the nutrients, and the water change should be increased at the same time. Absorbs dirt to keep the water fresh.
