Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of abalone breeding, in particular to a high-temperature-resistant abalone breeding method. BACKGROUND

[0002] Abalone is a precious marine product that has always been favored by consumers. Abalone breeding industry is not only an important fishery industry, but also a typical agricultural industry that is related to social stability and directly meets the basic living needs of the people. After more than 10 years of rapid development, China's abalone breeding industry has ranked first in the world, with an annual production of more than 100,000 tons of finished abalone, accounting for more than 90% of the world's total abalone production. It has brought 8-10 million direct employment opportunities and more than 2.5% of the fishery income to the coastal fishermen, creating huge economic, social and ecological benefits.

The hybrid abalone has poor adaptability to the high-temperature environment in the south in summer, and the problem of genetic degradation of abalone seed stock derived from cumulative inbreeding has always been a bottleneck restricting the efficient development of Fujian abalone breeding industry. In order to overcome the current difficulties, many breeders choose to transport abalone seed to the north for "summer crossing" to solve the problem of mass mortality and serious growth retardation of hybrid abalone caused by poor adaptability to high temperature in the south in summer. Although this method is effective, it is time-consuming, labor-intensive, and has certain risks and limitations. Only by introducing or genetically improving abalone seed to obtain "high-temperature-resistant" and high growth traits can the problem be fundamentally solved.

7. The method for breeding high-temperature resistant abalone according to claim 1, characterized in that, The screening tank (101) has several guide grooves (113) on its side wall. A guide plate (114) is provided in the guide groove (113). A jet port (115) is provided on the side wall of the guide groove (113). The jet port (115) is facing the guide plate (114). The jet port (115) is connected to the circulating pump (21).

8. The method for breeding high-temperature resistant abalone according to claim 1, characterized in that, The edges of the identification block are rounded.

9. The method for breeding high-temperature resistant abalone according to claim 1, characterized in that, Abalone that moved less than 1 meter in 24 consecutive hours were manually screened out, which further included: Observe the movement path of the abalone and determine whether the movement distance of the abalone is less than 1m for 24 consecutive hours. If not, do not take any action. If so, conduct manual observation to determine whether the abalone is dead. If so, clean up the dead abalone in time. If not, take out the abalone and place it in a cooling pool at the same temperature. The temperature of the isothermal cooling pool is the same as that of the screening device during operation, and the water temperature is gradually reduced by 1°C per day to 24°C and maintained.

10. The method for breeding high-temperature resistant abalone according to claim 1, characterized in that, The top of the upper box (1) is provided with an openable cover, and the cover has a notch opposite to the breeding tank (3).
