[0013] The present invention will be further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0014] An experiment on the temperature control method for the strengthened cultivation of silver pomfret broodstock:

[0015] Experimental fish:

[0016] A 1 year old female pomfret broodstock.

[0017] experimental design:

[0018] The temperature control during the broodstock cultivation of silver pomfret adopts the following 4 modes: cultivation at 18-19℃; cultivation at 18-19℃, and a low temperature stimulation stage of 12-13℃ in the early ...

Abstract

The invention relates to a temperature regulating method for silvery pomfret parents strengthening culturing. The method comprises the following steps: naturally reducing the water temperature of a silvery pomfret parents culturing pond to an interval of 12 to 13 DEG C, and keeping the water temperature at 12 to 13 DEG C for one week through heating; increasing the water temperature of the culturing pond to 18 to 19 DEG C according to an increasing amplitude of 0.4 to 0.6 DEG C every day; keeping the water temperature in the culture pond at 18 to 19 DEG C till the middle ten days and the last ten days of April in the next year, so as to ensure spawning and fertilization of silvery pomfret parents. The method can effectively promote the accumulation of nutrient in gonad tissues of the pomfret parents, obvioussy increases gonad index, fertilized egg quality and hatching rate, and finally improves the reproductive performance of silvery pomfret.

Description

Technical field [0001] The invention belongs to the technical field of temperature control during the breeding period of silver pomfret, and particularly relates to a temperature control method for the strengthened cultivation of silver pomfret broodstock. Background technique [0002] Silver pomfret is one of the main marine economic fishes in my country. In recent years, the East China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, through continuous in-depth research and exploration, has mastered the reproductive characteristics of silver pomfret, the law of gonadal development, and the mode and method of artificial breeding of silver pomfret, and realized the full artificial breeding of silver pomfret Breed. However, the large-scale breeding and breeding promotion of silver pomfret has not yet been realized. At present, the key technical bottleneck restricting the large-scale artificial breeding and breeding promotion of silver pomfret is that it is ...
