After years of sluggish growth, the goldfish market has gradually recovered. The prices of many popular varieties have increased year by year. However, with calm thinking, there are still problems such as quality deviations, small specifications, little new varieties, and lack of standardization of packaging technology in China's goldfish culture. Therefore, cultivating new varieties and improving the quality of goldfish are currently urgent problems to be solved.
The cultivation of new varieties of goldfish requires two basic technical conditions: one is to accumulate certain feeding experiences during the long-term feeding of goldfish; the other is to acquire a certain knowledge of biogenetics.
Determine the objectives: First select the dominant traits, design the image of the future new breeds, determine the cultivation objectives, and then determine the hybrid objects, so that the new varieties possess the characteristics of the two fishes, thus having higher ornamental value. For example, the dragon-eye tiger produced by the hybrid of dragon's eye and tiger's head has the characteristics of both dragon's eye and tiger's head, forming a perfect combination.
The choice of broodstock: broodstock must have strong physical fitness, obvious characteristics of the species, genetic stability is relatively stable, good color, early bleaching and other advantages, so we must have a more detailed understanding of the selected new fish. If the two ends of the new fish are sloppyly intersected, the consequences may not be ideal, or even a very bad outcome.
Backcrossing and stereotyping: The birth of a new breed of goldfish is not an easy task, and it is impossible to achieve the desired results through a crossbreeding. It takes unremitting efforts and it usually takes 3-5 years to shape. In the first generation after crossing, the ideal cultivator is selected according to the goal of cultivating and cultivating, and purification is performed. If the desired target is not achieved, backcrossing or cross-crossing and then purifying and breeding will be required to achieve the desired goal.
At the beginning of the new species, the hereditary traits are still unstable, and they must be continuously bred and purified year by year to make it produce relatively stable offspring and form a certain population. It is truly a dream to cultivate new varieties.
