Then remove the surrounding capsule with a trumpet curved mouth tweezers, and use a tweezers to press down from the sides and press down slightly to lift the pituitary. After the pituitary has been removed, blood stains and fat attached to the surface are removed for use or preservation.
Method for preserving the pituitary gland of fish: Put the pituitary into a vial containing acetone or absolute alcohol for dehydration. The volume of acetone (or absolute alcohol) is more than 20 times that of the pituitary gland.
10 hours or so for a new liquid, continuous exchange 2 ~ 3 times, remove the pituitary gland shade, bottled sealed, marked pituitary gland number and removal date, placed in a desiccator at low temperature to save. Injection can generally be injected into the abdominal cavity or injected muscle. If you are not skilled, it is better to use injection muscles. Generally, it is safer to select muscle parts above the sideline of the fish. Within about 1~3 days after the injection, it is possible to spawn, if not spawning, it is possible; first, the mother does not have an egg; second, the amount is wrong, too little or too much; three, the pituitary gland is out of date, or is not preserved Good is broken. After the female fish spawned and the male fish cloth was fined, the PVC pipe was moved to another small fish tank for artificial hatching. The water quality and insulation of the small tank are very important, and 0.3 ppm of methyl blue should be dripped down to prevent mildew and slight air bubbles. Before the hatching reaches 60 hours, the small fish is moved to another small pot or bowl inside the PVC pipe. After the fish are free to swim out, they can begin to feed artificial eggs. The artificial egg is coated with fingers. The inner wall makes it a tape with a width of about 0.3~0.5?, and can be fed by drying with a hair dryer. (Artificial egg diets are made of one raw egg yolk, one cooked egg yolk, a little cyanobacterial powder, a little bit of glutinous ingot, a little fat, a little binder, and a bit of brine shrimp. Stir it well and put it in the fridge for use). If the small fish will all swim to the bowl, you can start feeding. There are two ways to feed the fish. First, prepare a large bowl of dried egg slurry and gently pour the fish and raw water. Second, After the coated egg slurry is dried, the surface of the water is raised, so that the fish can be eaten higher than the egg slurry. After about one hour, it is necessary to lower the surface of the water and change about 45 to 50% of the water. The egg yolk will also be taken. Get rid of but don't get small fish, because if larvae are inhaled, they will behave as if they are in the sky. They will get sick in 1 to 2 hours and die. The new water used must be the same temperature as the bowl of old water, the same pH, the same alkalinity, the same minerals, as long as there is a difference, the small fish may return home to say goodbye. Changing the water depends on the size of the bowl. If the bowl is big enough to be like a basin, you can change the water for six hours. Only two or three times a day can. After feeding for four to five days, the 100% abundance of freshwater shrimp can be given as a normal bath.
The hatching of brine shrimp larvae is described below:
Add about 20 to about 10 grams of salt or coarse salt per liter of tap water, or about 1.0 to 1.02 parts of salt water, and add 2 grams of brine shrimp eggs to 1 litre of salt water. Use a round bottom. Or a hammer-shaped container is filled, and then the air is pumped so that all the eggs have enough oxygen, and the amount of aeration is changed after the first 8 hours of exposure with large aeration. After 24 to 36 hours, the invertebrate larvae are born and the bubbles will be born. Remove the stone and let stand for 10 minutes to allow the shell to float on the water. Instar larvae and dead eggs will sink below. Then take a thin air tube to draw the invertebrate to the fine mesh of 150 mesh and then remove the knot. The larvae and dead eggs are separated once or twice by the light collection method, and live non-spotted larvae can be obtained.
Feeding fresh shrimps from three to ten meals a day is convenient for individuals. After feeding one meal, changing 15% water or changing water all the time can be enough. The family's hometown has a few times, the shadows, the shadows, the Qins, the stupid soups, the swords, the alphas, the silks, the silks, the silks, the silks, the sands, the sands and the strong shoots.

Generally the fish will swim on the broodstock after the yolk nutrient absorption. If there is a problem with the quality of the water, the only remedy at this time is to take a try and pick up all the small fish. Old water into the small cylinder) temporarily placed in a small tank, and then change the spawning cylinder water (first brush cylinder) 100% and then fish back to the tank, the broodstock responsible for bringing back the small fish. If not, discard it. In the next change, a portion of the old water will be pumped to the small tank one day before the fish have yet to swim. Then the spawning cylinder will be moved to the small tank and the water in the large tank will be 100% full. Only afterwards will the spawning cylinder be returned to the spawning tank and the broodstock will bring the fish. The upper body can be fished into a larval tank to feed the freshwater shrimp no-larvae after 3 to 8 days.
If white eggs occur during hatching of eggs, they may be: (1) may not be fertilized, (2) may not have the right water hardness, and (3) may be invaded by Saprolengia in the water; A phenomenon has to try changing fish. The hardness of the water can only be adjusted again. For mold problems, try putting a little hydrogen peroxide or methyl blue to prevent the mold from attacking the eggs.
Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
