Goldfish breeding story
Goldfish History of goldfish breeding Asia has at least a Millennium and originated from children’s hobby to collecting in which the housing was offered and developed in cages, in pens, in wells, in tubs and barrels for all small and medium animals — as the first kind of Pets at home.
In China and Korea over a thousand years ago was engaged in not only fishing, but also breeding and raising goldfish. Over the years of breeding the Chinese fish farmers emerged and established natural mutations with drastic changes in body shape and structure of the fins, the eyes, the structure of the skin and staining fish were obtained decorative forms and color variations, which became the core of most of today’s known species.
The first written mention of the Golden fish with red scales came from China during the reign of the Qing dynasty (265-420 ad). In those days, these fish were spotted in a lake in the mountain Lushan, near the river of the City — near the modern province of Shaanxi, which flows to the South China and Northern Vietnam. In the ancient Chinese treatise Shan Hai Jing, presumably written in the late centuries BC — the beginning of our, there is also a record of the “red carp”. However, there is absolutely no certainty that these wild representatives were the ancestors of segodnyashnaya fish. It is assumed that the red coloration was obtained as a result of purposeful breeding work first pet lovers and falls on the reign of the Tang dynasty (618-907 years of the new era).
It is possible that the appearance of unusual forms and colors of goldfish had a direct influence of the religious community professing Buddhism: the manifestation of pity and humanity to the poor, while maintaining the ugly offspring of pond fish in a specially equipped farms and dams, and then in specially created containers and decorative vessels; not taking them for food. Thus, in China began to appear “merciful ponds”, and the practice of preservation of life and topstitching the death of the animal has become known as “Fang-Sheng” (life the releasing).
After 960-x, — already during the song dynasty, goldfish, along with many other animals, have become popular household Pets swimming pools. This period is perceived by the beginning of the domestication of goldfish and their satellites — objects and subjects of the water element. Originally, this decoration of wealthy houses and yards of rich landowners, the size of the territories that allowed them to arrange private ponds and pools with fountains.
The popularity and demand for goldfish has become a core business in mass breeding of fish and realization of human goods. Already in the XIII century there is a new kind of animal: — trade variations of the goldfish under the name “Yu-erh-Ho”. Starting from this period until the XVI century, the fish gradually move from pool to spacious aquariums are not only the very rich and nobles, but in the homes of middle class and lower class.Goldfish are omnivorous. In addition to the above plants, as the vegetable can be used fresh lettuce and nettle. Animal feed — bloodworm, Tubifex, earthworms and so on. Willingly eat hard boiled and washed in running water porridge rice, millet, buckwheat and other cereals. Maybe feeding dry food. It must be remembered that goldfish tend to overeat, leading to disease, however, it is this feature used for breeding new species of fish totalities fish are able to reproduce in the first year of life, but for breeding purposes it is better to wait until the fish reach full development — this occurs from ages two to four years.
The spawning season in natural conditions is in April — may. In the mating period, the willingness of the fish to reproduce manifests itself in their external appearance: the females and males on the Gill covers appear bumps millet pearl color, and the pectoral fins arise pylevidnye miniature notches. The abdomen of females, ready to spawn, growing in size. Males begin to actively pursue the females, trying to drive them into shallow waters and densely grown plants. Therefore, it is desirable that the water level in the spawning tank was not more than 20 cm.
The approximate volume of the aquarium for fish breeding — from 40 to 100 litres of clean settled water. Desirable good aeration and lighting. Since fish are prone to eating their own eggs, at a height of 1-2 cm from the bottom mounted coarse grid. You can use aquarium densely planted. Immediately after spawning, which lasts from two to five hours, manufacturers need to remove.
During the year animals are able to reproduce several times. The young hatch from the eggs in 2-6-day, which depends mainly both on the condition of the weather and water temperature, and direct sunlight accelerates their development, but the shadow, conversely, inhibits.
In continuation of the first days on release, the young fish move very little, mostly hang or lie between water plants and feed on their yolk bubble, which equips them for their original existence. But once this stock is exhausted, the fry begin to search for food. Hunger brings them from this state of torpor and force to move back and forth in pursuit of food. Feed the fry brine shrimp, rotifers or “living dust”. Acceptable use of special feeds.
With the development of fish carry out sorting according signs. Not all the fry will inherit the appearance of the parents, very often most of the brood are goldfish without any signs typical for each species. And Vice versa — from a nondescript manufacturers can be quite spectacular specimens.
