Embodiment 1

[0029] Such as figure 1 , shown in table 1, the embodiment of the present invention discloses a kind of temperature and light regulation and control method of off-season breeding of redfin puffer broodstock in industrialized recirculating water culture, comprising the following steps:

[0030] Step (1) Construct the temperature and light control equipment for broodstock cultivation of redfin puffer, which includes water storage and temperature adjustment pools, heating and cooling machines, LED lights and light environment controllers, broodstock ponds and circulating water systems ( figure 1 ). The water temperature of broodstock pond is regulated by cooling and heating machine. After the source water enters the water storage and temperature regulation pool, it is pumped into the cooling and heating machine for temperature regulation through the water pump, and the temperature regulation water flows back into the water storage and temperature regulation pond, or is introduce...

Abstract

The invention discloses a temperature and light regulation and control method for out-of-season breeding of fugu rubripes parent fishes and application, and belongs to the technical field of factory-like circulating water cultivation of the fugu rubripes parent fishes. The breeding period of the parent fish of fugu rubripes is concentrated from March to May, and the production of fries is limited by seasons. By simulating the illumination period and the annual change period of the water temperature, the change rate of the annual period is accelerated from one time of 12 months to one time of 6 months, gonad development of the parent fish is promoted to be advanced, and breeding and egg laying in winter are achieved. The fry obtained by out-of-season breeding is easy to be subjected to low-temperature masculinization induction.

Description

technical field [0001] The invention belongs to the technical field of industrial circulating water cultivation of red-finned oriental puffer broodstock, and in particular relates to a temperature and light control method and application of shortening the breeding cycle of the red-finned oriental puffer. Background technique [0002] The breeding time of fish is seasonal. Under natural conditions, seed breeding and production can only be carried out during the breeding season. Environmental factors that affect fish reproduction time include: temperature, light and nutritional conditions. Seasonal changes in temperature and photoperiod are closely related to broodstock breeding time. Photoperiod regulation is an effective means to regulate the spawning time of broodstock. [0003] Redfin puffer (Takifugu rubripes) is an important cultured species in the northern coastal areas of China. It is a summer breeding fish, and the breeding season is from April to July. Under artif...
