The ichthyosaurus cichlasomacitrinellun (Cichlasomacitrinellun), also known as the longevity fish, auspicious fish, and head of life, is affiliated with the cichlid family, originating from South America and Central America. It is a tropical fish that combines ornamental and food. The adult anthurium fish is generally 20cm to 25cm in length and has a strong physique and a variable body color, generally orange-red, white, and orange-yellow. It is suitable for a living water temperature of 23°C to 28°C. It has rough temperament and strong territorial awareness. Sometimes it can be seen. To two fish bite each other, resulting in both sides lose both, so the anthurium fish should not be mixed with small fish polyculture; flamingo fish eating fish, leeches, small live fish, shrimp, etc., artificial artificial particles can be fed after artificial domestication feed.
First, seed breeding
1. Breeding facilities for breeding broodstock breeding ponds are closed circulating water. The cultivating pool used is a cement pond with an area of ​​20 square meters and a water depth of 1.2m. The source water is hot spring water. The water quality complies with the aquaculture water standard and the water temperature is relatively constant. The water quality is clear and pollution-free. Prior to stocking the phoenicopteran fish, the broth should be disinfected with a chlorine dioxide solution at a concentration of 0.510E-6 and then refilled with fresh water.
2. Selection and breeding of broodstock When selecting broodstock, males are generally required to have prominent foreheads with brightly coloured bodies. The abdomen of female dorsal fins at the end of dorsal fins and anal fins is enlarged, and the dorsal and anal fins are rounded at the end. A cement pond with an area of ​​20 square meters is generally stocked with 10 to 15 pairs of brooded ichthyotic broodstock, with a male to female ratio of 1:1. Before stocking, the fish was sterilized for 20 minutes to 30 minutes with brovicid iodine solution at a concentration of 2010E-6.
When the broodstock is raised, it is usually fed twice a day. The feed is fresh fish or compound feed. The feed needs to be fresh, not moldy, and not degenerate, and the nutrient composition can meet its development needs. Vitamin E can also be added to promote the development and maturation of gonad gonads. Every day, regular discharge of sewage and filling with fresh water 20cm to 30cm, to create a good living environment for broodstock.
3. The breeding of the fire crane fish grows rapidly. After 8 months to 10 months of culture, the gonads are mature and can be propagated. When two fishes were found to be alone, the two fishes showed a strong sense of consciousness when they tried to approach each other, and they would bite other fish, indicating that the two fishes had developed their love; or they found males. The genital protuberances are drooping and slightly slender, while the female's abdomen is enlarged and the ovipositional tube is thick and short, which significantly protrudes from the body. At this time, the male and female broodstock should be promptly taken out and placed in a spawning or spawning tank, and in the pool. Or put a marble or a flowerpot as the ovary in the bottom of the tank. Spawning ponds, spawning jars, and ovaries should be soaked in potassium permanganate solution at a concentration of 2010E-6 for 30 minutes prior to use, and then rinsed and used.
Breeding water temperature control in 27 °C ~ 28 °C, until the male and female broodstock familiar with the surrounding environment, it will take advantage of the mouth spawn spawning plate, clean, the time will mature, the female will spawn spawning spawning plate, male Immediately after the release of semen, the fish release fertilization. This process is commonly referred to as "walking." After about 40 minutes to 60 minutes, spawning is nearing completion. The female lays between 800 and 1000 grains per spawning. During this process, the broodstock will swallow the shed and white eggs with their mouths. Therefore, spawning plates or broodstock should be promptly laid after the spawning. fish out.
It should be noted that the water quality of hatching fertilized eggs is consistent with the water quality of the spawning pool so as not to affect the hatching rate. During incubation, pay close attention to changes in water temperature, should absolutely avoid the sudden increase and sudden drop in water temperature, and control the dissolved oxygen content in the 5mg/L ~ 6mg/L. After 48 hours to 72 hours of hatching, the larvae break out of the membrane and gradually fall off from the spawning plate and fall to the bottom or bottom of the tank.
The newly hatched larvae have yolk sac. During the first 2 days to 3 days, the larvae absorb their own yolk sac to maintain their lives, and finally they float and swim to the surface. When the larvae swim to the surface one after another, the yolk sac is basically absorbed. At this time, it is necessary to feed the open bait in time, such as egg yolk leeches. It is a common name for several planktonic protozoa to ensure that larvae can ingest adequate and palatable The bait comes to life. After another 7 days to 10 days, rotifers, cladocerans, and copepods can be fed. According to stocking density and water quality, stocking density should be reduced in time to divide the stock, and at the same time increase the amount of water exchanged. Sewage to keep the water fresh.
Second, seed cultivation
1. Seed cultivation ponds and water quality Requirements Seedlings cultivation pond area is generally 20 square meters to 40 square meters, water depth is about 1.0 meters, using closed circulating water for aquaculture, the water quality meets the aquaculture water quality standards, the concentration of culture ponds before stocking is Disinfect the 0.510E-6 chlorine dioxide solution.
2. Seed stock quality requirements Stocking stocks require strong physique, neat specifications, strong ability against water, shiny surface, sensitive to external stimuli, plump muscles, eyes plump and bright, scales neatly arranged, fins without defects, fistula tissue Bright red and free from parasites.
3. When the stocking stocks are stocked, they should be sterilized with a povidone iodine solution with a concentration of 2010E-6 for 15 minutes to 20 minutes. For fish fry with a size of 2 cm to 3 cm, the stocking density is generally 250/300 m/m. Square meters.
4. Feeding and daily management are fed 4 to 6 times a day. The feed can be red worms, small fish or pellet feed. The fresh fish worms are sterilized with 4% saline before feeding for 10 minutes and rinsed. Feeding. The aquaculture water temperature is controlled at 26 °C to 28 °C, and the sewage is replenished every day and fresh water is added to keep the water clean.
Third, adult fish breeding
1. Adult fish breeding pool requirements Adult fish breeding pond area is generally 40 square meters to 100 square meters, water depth is about 1.2 meters, using closed circulating water for aquaculture, the water quality meets the aquaculture water quality standards, the breeding pond is used before the stocking concentration of 0.510 The chlorine dioxide solution of E-6 is disinfected.
2. When stocking fish stocks, they should be sterilized with a concentration of 2010E-6 povidone iodine solution for 20 minutes to 30 minutes. The stocking density is generally 25 to 40/m2.
3. During the feeding of adult fish, the protein content should be more than 30%, and it is best to use extruded pellet feed. Feeding adheres to the principle of “Four Sets†and feeds 4 times a day.
4. Daily management Aquaculture water temperature is maintained at 26 °C ~ 27 °C, according to the need to add new water at any time to adjust the temperature. Keep water circulation for 24 hours every day and the water quality is clean and clean. Pay close attention to the observation of fish activity and find that problems are solved in time.
Disease prevention and control The fire-bred antha has a good ability to resist disease and has a high survival rate throughout the breeding process. The common diseases are mainly bacterial enteritis, gill disease, echinococcosis, and trichoderma. Because there are no contraindications to commonly used drugs, the prevention and control of diseases can be based on the control methods of conventional fish.
