Hibiscus is a new type of crossbreeding and systematic breeding between the Hunan Academy of Fisheries Research (telephone) and the original fish farm of Hunan carp.
In the breeding process, scattered phylogenia philippinarum, Xingguo red peony, and red peony were used as crossbreeding stocks. Population breeding and hybrid breeding techniques were adopted. The breams were bred for more than 3 generations, and the red locusts were selected for more than 6 generations. Parents that have been selected have stable traits, consistent body shapes and low coefficient of variation.
The morphological features are grayish-yellow, flat-faced, with higher and thicker back than normal fleas, close-fitting body scales, 20% of individuals without mouth vesicles, and 1 or 2 small fibrous roots in other individuals; body length is 2.28 to 2.84 times of body height. The head length was 3.21-3.87 times, which was 4.74-5.83 times the body thickness, and the tail shank length was 1.07-1.34 times higher than the tail shank height.
The comparison of growth advantage with the pool culture showed that the growth rate of the hibiscus species in the year was 17.8% faster than that of their parents, 102.4% faster than that of the parental red locust, 83.2% higher than that of the female parent hibiscus, and the growth rate of the second-year hibiscus larvae. 56.9% faster than the average parental level, 7.8 times faster than the parental red locust, 86.2% of the parental hibiscus; 3rd instar hibiscus growth rate is 54.1% faster than the average parental level and 7.6 times faster than the parental hibiscus. 84.5% of the mother hibiscus. The growth rate of hibiscus was 23% faster than that of Xiangxi, 53.1% faster than Pengze, and 34.8% faster than that of silver.
Resistant to strong hibiscus feeding complex, wide adaptability, resistance to oxygen, dephosphorization and congestion, and infection, so resistant to operation and transportation, suitable for catching "hot fish" in the hot season, live fish for long-distance transport, the survival rate increased by 10 %the above.
