Abstract

The invention relates to the field of fish culture, and aims to provide a method for domesticating mandarin fish fries. The method comprises the following steps: selecting mandarin fish fries with consistent body lengths and weights as domesticating objects; putting the selected mandarin fish fries into a domestication pool for acclimatization, carrying out cluster training for three days, and then sequentially carrying out eight-day chilled bait fish domestication, nine-day soft granular feed domestication and nine-day hard granular feed domestication. According to the method provided by theinvention, chilled bait fishes and a soft granular feed are used as intermediate domestication transitional baits for domesticating the mandarin fish fries which are subjected to cluster training, themandarin fish fries are subjected to continuous domestication to completely eat a hard granular feed, and a certain amount of the adapted bait in the previous stage is continuously fed after the newbait is fed in each feed changing process so as to ensure that the mandarin fish fries are fed fully, the probability of cannibalism is then reduced, the domestication survival rate and the growth rate are effectively improved, the operation is simple, and the large-scale production is facilitated.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a method for taming mandarin fish seedlings. Background technique [0002] Mandarin fish, also known as sweet-scented osmanthus fish, belongs to the order Perciformes, and is a typical ferocious carnivorous benthic freshwater fish. It is mainly distributed in rivers and lakes in the eastern plains of my country. It is one of the rare freshwater edible fish. The germplasm resources of wild mandarin fish are depleting day by day due to the continuous human destruction of the ecological environment of natural waters and overfishing. Although mandarin fish artificial propagation technology has been successful in recent years, there are still many problems in the large-scale production of seedlings. At present, the research on mandarin fish mainly focuses on physiological ecology, genetic characteristics and feeding habits, and few studies involve the domestication of mandarin fish to ea...
