Goldfish breeding - hatching management of fertilized eggs

9. Incubation and Management of Fertilized Eggs Wash the aquarium (pots and cylinders) and inject it into the newly-dried water. Then, it can be used as a hatching pool. When the water temperature meets the water temperature required by the spawning pool, it is placed in the nest of eggs. In a hatchery of 2m square, about 6 fish nests can be placed. Do not overtight. Because hatched larvae go to juveniles in the previous stage, they must live 20-30 days in the pool. Fertilized eggs are translucent orange-yellow eggs with a diameter of 0.1-0.2 cm. About 24 hours after spawning of females, if a milky white egg appears on the nest, it is an unfertilized egg and will die at any time. It should be gently removed with a photon in time to avoid deterioration of water quality or water mildew due to rot. Infected and endangered the whole pool; the orange-yellow fertilized eggs hatch at 2-3 days at 15-16°C; from the appearance, the transparency of the fertilized egg gradually decreases, and a small black spot appears gradually. This is the first formation The head of the young fish is called the eye point. In another 2-3 days, a round body of flesh is gradually formed around this dark spot, which is the body of the goldfish. At this time, under the magnifying glass, it can be seen that the tail of the larvae constantly oscillates in the granules, breaks continuously, becomes weaker and stronger, and finally breaks out of the eggs. In the appropriate temperature range, the length of hatching varies. With high water temperature, incubation time is short, and vice versa. When the average water temperature is 15-16°C, the incubation time is about 7 days; when the water temperature is 18-19°C, it takes only 4-5 days; if the water temperature rises to 20°C, the larvae can be hatched in two days. However, with the water temperature of 16-18°C, the larvae hatched after 6-7 days have the best physique. During the incubation, it is necessary to prevent rapid changes in water temperature, such as strong sunlight during the day, high temperatures, or sudden changes in the climate. When cooling, take measures such as covering the curtain or plastic film to prevent the water temperature from rising and falling. At the same time, to keep the water fresh and the surface of the hatchery covered with dust, use a clean gauze to gently remove it along the water surface. In the reproduction of goldfish, if one considers the influence of environmental factors on the breeding activities of goldfish, conscious artificial control is also very beneficial, such as a fish nest made of fresh water grass, new water with good oxygen content, and a day before rain. Meteorological conditions can stimulate broodstock oviposition. But the most important is the water temperature. The optimum temperature for goldfish breeding is 14-18°C. When broilers hatch at 18°C ​​or so, the larvae developed the best and the physique is the most robust. Therefore, in the breeding season of goldfish, it is necessary to make full use of these laws. For example, during the incubation period, try to keep the water temperature stable at around 18°C ​​so as to ensure a healthy larvae.

Fried Food is one of the traditional foods in our country, whether it is fried rice, fried spring rolls, croquettes, or fried dough sticks, oil cakes, noodles, and French fries in children's favorite snacks. Fried bread, fried chicken wings, and fried potato chips and fried biscuits in snacks are all fried foods.
Deep-fried foods are popular among many adults and children because of their crispy taste, aroma, and appetite. However, frequent consumption of fried foods is extremely detrimental to health.
