It belongs to the country ' s second category of protected aquatic wildlife, which, because of the similarity of their voices and the crying of their children, is called a dollfish. Because of the fact that the bird's internal organs can be administered to the whole population, it is being hunted down by humans. The mahogany is mainly inhabited by streams in mountain areas and prefers to live in caves with backwater.
The main species of dollfish sold in the market should be such, and the book records that brookfish, although also called dollfish, are minor species. Large and flat, all of them can grow up to 1800 mm and most common 600-700 mm; their heads are flat and wide, their bodies are thick and flat, their tails flat and their tails flat. The length of the head is approximately the same; the length of the kiss is the same; the length of the kiss is the blunt circle; the nostrils are very close to the end, the eye is too small, the eyelids are missing, and they lie on the back of the head; the mouth is cracky, the upper lip is not prominent behind the rear corner of the eye, and the lower lip is clear behind the mouth; the upper and lower cheeks have fine teeth; and the right and left of the ploughing bone are in arc parallel to the upper jaw, with a flat tongue attached to the bottom of the mouth. When the limbs are short and fat, and the acoustic, the toes are very far apart from each other, with a distance of about six ribs, with a very wide and short toe, with a blunt end round, and a microtip on the outer side of the four toe base; four, a little longer than one or four fingers; toe-five, with a sequence of 3, 4, 2, 5, 1; and a well-developed exterior skin of the fourth and fifth toe. The length of the tail is one third full, the tail is tall and thick, the tail is thick and thick at the bottom, and the abdominal fin is visible only near the tail. The anal cavity is short and short to crack.
The skin tends to be smooth, the back abdomen of the head consisting of two small pairs of beaks, the kisse of which is more dispersed; the visible lined up from the pillow up to the upper eye, where there is a branch of the beak which is linked down to the lower side of the eye and the lower side of the neck; and the beaks that follow the lower lip to the back end of the mouth and fold back to the lower part of the throat. From the side of the neck to the side, there is a visible skin wrinkle, with two large and unmatched pellets on the top and lower of the wrinkle. They also have skin edges, toes on the outside and more developed back limbs. There are 12-15 ribs on the side. The stockbreeding environment
The maggot is extremely ferocious and very agile, because it belongs to amphibious aquatic organisms and sounds like a baby. It is important to provide a suitable rearing environment for large-scale animals in an artificial environment where they can live for more than 50 to 60 years.
1. Pond selection and seed preparation
A fish pond of 5 acres with a depth of 2 metres. Sufficient water sources are required, and self-drained. After disinfection, two to three pounds of soybeans per acre were used for the three days prior to seeding to ensure sufficient biofeeds to feed the bait fish. Before entering the pond, sufficient bait fish is to be prepared and before seedlings are to be placed into the shoals, such as carp, mackerel and shoalfish.
Sources of seedlings and conditions for their release
The sapling seed is from the quarries of Hebei Province and originates from the Erzis River in the northern part of Xinjiang, with specifications of 4-6 cm/tail, with 10,000 tails. In May, large seedlings were purchased and water temperature remained constant at around 20°C and PH 8. 0, ammonia 0. 1 mg/L, nitrite 0. 1 mg/L.
3. Farming patterns
The masonry is monolithic, 600 tails/acres, and no other fish is integrated.
4. Water quality regulation and bait feeding techniques
The water quality of the big acupuncture is thin and transparent to about 40 centimetres. The water quality requirements are similar to that of herbs, but are not resistant to low oxygen and can float. Biofertilizers and EM liquids are used in water quality regulation. I'll feed you.
The basalm is amphibian and can be breathed in water with gills and outside of water with lungs and skin. The second category of this country, which protects aquatic wildlife, is ferocious, and the tooth of a large tummy cannot be chewed, so the food is eaten slowly in the stomach.
Artificial larvae are mainly fed to carp, and to the meat baits of the summer flowers. With the growth of the basalm, the caliber specifications and quantities of the fish required for the bait are increasing and timely feeding is required. In the wild, the predators are extremely subtle. Every time he sees a small animal coming in, he tries to stir up the water with a thick tail, hides himself and looks at himself. Watching the little animals that swim, they bite them up at a certain distance, then they eat them three or five times less than half, with the rest hanging over their teeth for next time.
