Problems solved by technology

However, up to now, no mature technology for promoting the gonad development of male redfin puffer has yet to be established, and the gonad development time of more than half a year increases the cost of breeding. Therefore, there is an urgent need for a method to promote the gonad development of male redfin puffer.

Embodiment 1

[0015] On September 23, 2020, at the industrialized breeding base in Dalian, Liaoning, an LED light source was installed 1.5m above the center of the water surface in the fish breeding pond for redfin puffer, and the light intensity to the water surface was 1.5W / m 2 , the LED light source is full-spectrum white light, put 2.5-year-old red-finned puffer into the fish culture pond of puffer, turn on the light at 8 o'clock every day, turn off the light at 20 o'clock, the photoperiod is 12h light and 12h dark, and feed the bait once a day , fed with full food, the bait includes 0-10% compound feed, 60% fresh squid and 30-40% fresh clamworm by mass fraction, the breeding cycle is 100 days, and the water temperature of the breeding water body is maintained at 16-22°C during the breeding period And the daily change does not exceed 3°C, the salinity is 28-32‰, the pH is 7.5-8.0, the ammonia nitrogen is less than 0.2mg / L, the nitrite nitrogen is less than 0.1mg / L, and the dissolved oxyg...

Abstract

The invention relates to a method for promoting gonad development of male takifugu rubripes, and belongs to the technical field of takifugu rubripes breeding. From September or October, an LED light source is arranged above the culture water surface of 2.5-age and above takifugu rubripes, the LED light source is full-spectrum white light, the light period is 12-hour illumination and 12-hour darkness, and the culture period is 90-150 days. By creating a specific light environment, the gonad development of the male takifugu rubripes is promoted, the gonad development time is shortened, and the economic benefits of breeding enterprises are improved.

Description

technical field [0001] The invention relates to a method for promoting gonad development of male red-finned puffer, and belongs to the technical field of red-finned puffer culture. Background technique [0002] Red-finned puffer (Takifugu rubripes), commonly known as puffer, is the largest species of puffer fish with high economic value. It is mainly distributed in the East China Sea and the Yellow and Bohai Seas in China. The red-finned oriental puffer is known as the "king of fish" because of its tender meat and delicious taste. It is the main species of high-end fish consumption, and it is also an important foreign exchange earning target for exports in northern China. The annual production of red-finned oriental puffer in my country More than 4000 tons. Most of the artificially bred male red-finned puffers are sexually mature at the third age. The testes of the male fish are non-toxic and delicious, and the market price is as high as 1,400 yuan / kg. However, up to now, n...
