Turtlefish - Geographic distribution
The turtle is found in rivers and lakes all over Jiangxi. Among them, Poyang Lake, the largest freshwater lake in China, is the most abundant and has the best quality. Ten years ago, Dajiling Reservoir, a suburb of Nanchang, built a base for artificial reproduction of snappers,
Snappers - habits
Snappers are amphibious animals, breathing with the lungs, soft-shelled turtles do not have gills, out of the water and crawl with the lungs to breathe, there are nostrils, trachea, bronchial tubes and the lungs and other perfect respiratory system. It has a perfect respiratory system including nostrils, trachea, bronchial tubes and lungs. The lungs are large and bubbly, spongy, and very adaptable to life in water. The mucous membrane of the turtle's pharyngeal wall is also covered with capillaries for gas exchange in the water, and with the gulping of water from the mouth, gas exchange in the water is also possible. Therefore, during the hibernation period, the soft-shelled turtle can absorb the dissolved oxygen in the water to maintain its life by sticking the tip of its mouth and its tubular nostrils to the surface of the mud and sand close to the bottom of the water. Because the turtle has the above special organs, it can dive underwater for a long time.
In the warm regions of the water system, the turtle's growing period is very long; in the northern regions, when the north wind whistling frost paved the ground, the grass decline and reed failure of the green water cold season, the turtle hibernation submerged in the sand, do not eat and do not move. The soft-shelled turtle usually lurks in the underwater sand, with its head and neck hidden in the body and its eyes gleaming as it peers at the underwater world. When fish and shrimp swim to its side, it will suddenly stretch its neck and attack, and it will not let go of its bite. In the late spring, hot summer and early fall season, the waves are calm and warm, green fungus pavement, they often climb to the shore to sunbathe. Around noon in the hot summer when the wind and waves are calm, they often float to the surface of the water and stick their tubular noses out of the water to breathe air. At the slightest breeze, they immediately dive into the water. In the warm season, every cloudy and rainy day with low air pressure, the turtle also swims to the surface of the water to breathe, and sometimes the whole body is exposed to the water. Especially in the cloudy, pouring rain, rising rivers and waves, there are often dozens of kilograms of old turtles to look around.
Turtle-Reproductive characteristics
Turtle egg identification and collection After collecting turtle eggs, the spermless eggs should be eliminated. Identification of fertilized and spermless eggs can be judged from the appearance of the eggs at 8-30 hours after spawning according to the temperature. Fertilization marks in the early stages of embryonic development, there is a round white spot on the top of the egg, clear around the white spot. The white dot is surrounded by a clear, rounded, bright area. In the process of development, the white spot gradually expanded to the scarf. The white end is the animal pole. Eggs that have not been fertilized, the top of the eggshell without white spots, or large irregular white spots, but in the process of development will not expand. Sablefish egg collection can be done by entering the spawning grounds before sunrise to look for spawning nests. Before and after the snapper spawn, be sure to word the hole and cover the mouth hole with sand. Snappers dig out of the sand is wetter than the surface layer, according to which it is not difficult to find spawning nests; grass, under the roots of the tree is also often a concentration of egg nests.
Snappers - feeding methods
Snappers feeding 1. Bait table placement and cleaning Bait table is best placed in the breeding pool around the edge of the pool, and with the water surface at an angle of 30-45 degrees, which is conducive to the snappers to find food and avoid interference. Before each feeding, the bait table and its surrounding area should be cleaned with a disinfectant solution with little irritation and a disinfected brush, and disinfected once every 3 days.
2. Production and placement of bait The amount of fresh material added is generally 10%-40%. When using fresh material, it must be sterilized, cleaned and used now to avoid spoilage. When feeding, the bait should be fed in the form of feeding, and the bait should be 2-3 centimeters away from the water surface. Snappers are timid, feeding should minimize its interference. The amount of feeding should be 1-1.5 hours to finish eating as standard, and the remaining bait should be collected in time for other uses. The feeding time in the high temperature season should be finished before sunrise and start feeding at sunset.
3. Water quality regulation Breeding water body should be regularly changed sewage, each time the amount of water change to no more than 1 / 3 appropriate, if the conditions of micro-flow culture will be better. In the breeding process, the regular use of chlorine dioxide preparation 0.5-1ppm, bleach 2-3ppm, strong chlorine essence 1-2ppm, quicklime 15-40ppm whole pool splashing disinfection, the application of medicine 2-3 days after the application of medicine 2-3 days after the whole pool splashing about 5ppm of photosynthetic bacteria preparation, can play a role in water regulation, 1-2 times a month can be.
4. The surface of the water planting green, build the sun back platform in the pond from the bait platform about 1 meter around a 1.5 meters long and wide frame, planting water hyacinth. Water hyacinth root system is developed, can absorb harmful substances in the water and play a role in water regulation, but also conducive to the snapper hide, sun back, cool. Pond side slope less breeding pond should be built in the pool sun back platform.
5. Regularly inspect the pond, remove the sick and dead snappers in time Inspect the pond in order to understand the snappers feeding, growth activities, diseases and pond water quality, facilities and so on. The dead snapper should be buried or incinerated in time, and the sick snapper should be isolated and treated in time.
