Green turtles can have long hair on their shells. What is hair? Is it your own hair?

Green turtles originated in nature, and it is common to see that the shells of some animals living in water, such as snails, mussels and shrimps, are covered with algae. Tongxiang, the shell of soft-shelled turtle is also a hard shell rich in calcium, which can grow "hair" under suitable conditions. This kind of hair is a kind of algae, a primitive lower plant, an independent group in the plant kingdom and an autotrophic organism. Their filaments are thick and have strong adhesion, so they are called basidiomycetes and basidiomycetes. When algae grow and develop in water to a certain stage, bears breed offspring. A large number of swimsuits are released by algae, and swimsuits keep swimming in the water. If there is an opportunity to land on the turtle's back, the bathing suit will carry calcium seeds on the turtle's back and secrete mucus. Under suitable conditions such as temperature, light and water quality, swimsuits will germinate and produce new algae. It can be seen that the "hair" on the turtle's carapace is not inherent in the turtle itself, but algae adheres to the turtle's carapace and abdominal carapace under certain suitable conditions, which is an integral combination of animals and plants, so it is called "green-haired turtle". As early as "Compendium of Materia Medica", there were records of green turtles: green turtles went out of Neixiang, Nanyang and Tangxian. At present, in nature, wild green turtles are mainly produced in Xinchun County, Hubei Province and Changshu County, Jiangsu Province. The green turtle is a rare ornamental animal, which is very interesting whether it is still or moving in the water. As a new aquaculture industry, the green turtle is developing continuously. It has the characteristics of less investment, small land occupation, no geographical restrictions and high income. So raising green turtles is a new way to get rich. In the process of breeding or raising green turtle, the position and length of green turtle are different due to different means and management methods. So green turtle lovers determine their names according to the different parts of algae attached to turtles. Generally, there are the following varieties: 1. There are algae on the head, forehead, four legs, carapace and abdominal carapace of the champion turtle. 2. There are algae in the crustacean and the carapace. There is an algae bread worm on the tortoise's shell. 4. There are algae on the front or back feet of the double-tasselled turtle. 5. One foot of the single-tasseled turtle has algae. 6. The peony head only grows algae on the turtle's head. Among the species of green turtles, Mudantou and Wuzi are rare species, and the rest are common species. The characteristics of green turtle species are very unstable and sometimes change. Due to improper management, turtle disease and other factors, it will affect the growth of algae, such as peony head, turtle head ulceration, skin peeling, green algae will also fall off. The change of single ear and double ear will be greater. In addition, when evaluating green turtles, we should also consider the species, size and color of green algae. Generally speaking, the four-serving turtle is more precious, and the dark green algae is the best, and the size of the turtle is 30 ~100g. Breeding of Green Wool Turtle "Green Wool"

1. Species of Turtles for Shooting In nature in China, there are 23 species of freshwater turtles. Generally speaking, all freshwater turtles can be used to breed green turtles as long as they can meet the conditions for the growth of green algae, but the following two conditions must be met: (1) Cladosporium or Cladosporium is an algae plant living in water, so there must be water. (2) There must be Cladosporium or Cladosporium swimming in the water where turtles live. These two conditions are indispensable. Green-haired turtles widely cultivated in China are: soft-shelled turtle, yellow-throated water turtle, dry-breasted turtle, four-spotted turtle, golden-headed box turtle, etc., among which the most commonly used one is hairy turtle. Second, the selection of algae species Whether the selection of algae species is correct is the key to the success of cultivating green turtles in abalone. Therefore, before breeding green-haired turtles, we must first understand what the "green hair" on green-haired turtles is. After the research of scientists, the body of this turtle was found. "Green hairs" are basidiomycetes and basidiomycetes. They belong to Celastrus, Chlorophyta, Diptera and Diptera. Basidiomycetes are green in color, like light green in water. Filaments are filamentous, thick and not easy to break. In the wild, it is usually distributed in rivers, lakes, streams, ponds and streams, but the number is small. In mountain streams, there are more basidiomycetes attached to rocks, shaft walls and ship walls. A large number of algae grow in nature, and they can also attach to the shell of turtles. However, some filaments are thin and brittle, and some larvae are attached to grow in the later stage of growth and live a floating life. These algae are not suitable for breeding green turtles. Therefore, in the process of selecting algae species, the correct identification of algae species is the key link. The characteristics of distinguishing Cladosporium from other filamentous algae species by naked eyes are summarized in the following table. The difference between Cladosporium and other filamentous green algae The characteristic Cladosporium of this algae is dark green, and it feels rough when touched by hand. There are no branches or only branches at the base of algae filaments, which are thick and tough and not easy to break. Other filamentous algae are light green, yellow-green or green with black. Touch the filament with your hands, and it feels smooth or slightly rough, with branches or multiple branches. Most of them are in the upper part of filaments, which are thin and soft and easy to break.

3. Preparation before algae culture (1) Pots and porcelain pots can be used as containers, but no matter which container is selected, its inner wall should be smooth, and there should be no defects or other decorations to avoid damaging the green algae. The size of the container is suitable for turtles to move freely in it. (2) The selection and breeding of turtles used for breeding green-haired turtles require that the turtles are strong, take the initiative to eat, and the membrane armor on the back is not damaged, and quickly sink to the bottom after entering the water. The size of the tortoise depends on the need. If you choose a turtle, you should choose a female one, because the male one smells fishy and should not be chosen. Before inoculation, clean the tortoise shell, especially the mixed algae on the carapace and carapace. Soak in 8 mg/L copper sulfate solution for 30 minutes, then rinse thoroughly with clear water, and finally soak in 2 mg/L potassium permanganate solution for 30 minutes. After brushing, soft-shelled turtles need to be fed food intensively twice a day. Before inoculation, they should stop eating 1-2 weeks, and let the soft-shelled turtles discharge all their feces to avoid polluting the water quality during inoculation. (3) Treatment of tortoise shells Before inoculation, it is necessary to treat tortoise shells and abdominal shells, and grind them rough with grinding wheel or sandpaper, but the surface of tortoise shells should not be excessively damaged to avoid inflammation and adverse consequences. (4) The water used for seed inoculation of Dalbergia odorifera, preferably the water replaced by feeding green turtles, is precipitated and filtered before being reused. If not, well water and exposed tap water will do. The suitable pH value of water is 7.5-9.5. (5) Before cleaning and inoculation of mushroom seeds, clean the miscellaneous bacteria on basidiomycetes, and pick up ciliates, rotifers and trematodes with tweezers. Because some algae buds are rootless basal branches, line segments with basal branches and bright green larvae with basal branches, they do not form ascomycetes, but germinate and reproduce. (6) The growth rate of aquatic plants with debris on the bottom branches at inoculation time is related to factors such as light and water temperature. The lowest water temperature of basidiomycete robe is 65438 03.5℃, the highest water temperature is 28.5℃, and the optimum water temperature is 20 ~ 24℃. Therefore, the best inoculation time for breeding green turtles is spring and autumn. (VII) Inoculation methods There are many methods to inoculate Cladosporium in China. The following is the simplest and only effective method: 1. Natural inoculation method Natural inoculation method is that the green turtle and the turtle to be cultured are together, and the baby released by algae swims in the water and has the opportunity to attach to the turtle to be cultured. The specific operation method is as follows: divide the larger container into 4-5 small squares with metal mesh, put the green turtle and the turtle to be cultured in it, and after 2-3 months of culture, if the turtle to be cultured grows short green fluff on its back, it should be cultured alone immediately. The disadvantage of this method is long time. & ltbr & gt2. The water for breeding green turtles is kept by soaking in nutrient solution. After 24 hours of precipitation, the bottom dirt is sucked up with a hose and 2/3 of the water at the top is poured out. Soak the soft-shelled turtle to be cultured in the artificial nutrient filler for 24 hours to accelerate the growth of green algae. The preparation method of the nutrient solution is as follows: taking white grass root 1 plant, white sugar 1g, white ginseng 1g and fish scales (preferably black fish scales) 5g, grinding and crushing, adding water and stirring evenly. Add a group of green vines similar in size to the turtle's back into the container. In the meantime, don't change water or feed. After 10, change the water every 2-3 days 1 time, and the water temperature difference shall not exceed 3℃. In this way, green algae can be cultivated in 1 month. 3. soaking NAA in NAA solution is a punishment for plant growth regulation. In the process of breeding green turtles, adding a certain concentration of water lily to the breeding water can promote the formation of Cladosporium spores. Put the treated turtle to be cultured in a container filled with bath liquid, and add 0.1~ 5mg/L sodium acetate solution. The cultivation method is the same as the nutrient soaking method. Adding NAA can advance the lint time by 4 times. Section IV Breeding and Management of Green Turtles Although the farmed green turtles have grown "green hairs", their future management is very important. As the saying goes, "three-point support, seven-point management", if the management is not good, "green hair" can fall off or turn yellow. The green turtle is the product of the combination of animals and plants, and the biological characteristics of the two must be organically combined in feeding management. First, the feeding habits of green-haired turtles vary from turtle to turtle. But they are generally eat small fish, shrimp, lean pork and so on. Feed/kloc-0 every two days in spring and autumn, and feed/kloc-0 every three to four days in summer. It is advisable for turtles to finish eating every time. No feeding in winter. Second, the water-changing green turtle has lived in water for a long time, and the debris on its feces, epidermis and body surface has accelerated the change of water quality, thus affecting the growth of Chlamydomonas. The frequency of changing water depends on the season. Due to the high temperature in summer, water must be changed after feeding. Change water 1 time every 3-4 days in spring and autumn, depending on the water quality in winter. When changing water, first prepare a basin of clean water, wash the soft-shelled turtle in the original container 1 time, then wash the "green hair" in the prepared basin and comb it gently with a sparse comb. Finally, sink the container, inject fresh water and let the turtle go. Pay attention to the change of old and new water temperatures when changing water. Generally, the temperature difference is less than 3℃. 3. Light is the basic condition of photosynthesis in the base branches of green turtles. When the light is insufficient or too strong, algae tend to turn yellow and white; The most suitable light for algae growth is scattered light. In spring and autumn, the cylinder should be exposed to the sun for 3 ~ 6 hours. In summer, due to the strong sunshine, it is not appropriate to directly place cylinders outdoors, and radiation should be carried out or a shade shed should be built. In winter, the tortoise will be moved outside to bask in the sun at noon, but don't move outside when it is cold to avoid catching a cold. 4. Winter 10 Late June to April of the following year is the hibernation period of turtles. When the temperature drops to 16- 10℃, the tortoise stops eating and does not move. Healthy turtles should hibernate naturally, change water 1 time every 2 ~ 3 weeks, appropriately increase the light, and pay attention to heat preservation when cold comes. Weak soft-shelled turtle should be raised by heating.
