Problems solved by technology

On the contrary, it also has the disadvantage that in order to produce more than 350 g of commercial puffer obscurus, long-term breeding of more than 30 months is required.
As mentioned above, puffer obscura needs to be raised for a long time, so there is a possibility that productivity may decrease due to disease, heating costs and labor consumption for wintering may increase, and there are problems such as high co-feeding rate.

Abstract

According to the present invention, provided is a production method of a crossbreed of Takifugu obscurus and Takifugu rubripes, which comprises the following steps: extracting ova and semen from female Takifugu obscurus and male Takifugu rubripes respectively; performing artificial fertilization to obtain fertilized ova; and incubating the fertilized ova and breeding the same. According to the present invention, a new crossbreed of Takifugu obscurus and Takifugu rubripes produced by the production method has an advantage of rapid growth rate, thereby allowing the promotion of existing puffer culture industry declining due to low production rate and low economical efficiency.

Description

technical field [0001] The invention relates to a hybrid between OLIVE TAKIFUGU OBSCURUS and TAKIFUGU RUBRIPES and a hybridization method thereof, and more particularly, to a kind of OLIVE TAKIFUGU OBSCURUS and TAKIFUGU RUBRIPES Hybrid species and production method therebetween, which comprise extracting eggs and semen from females of pufferfish and males of pufferfish, and performing artificial insemination between them to obtain fertilized eggs, incubating fertilized eggs and The step of cultivating is carried out so that a cultured variety with a rapid growth rate can be produced. Background technique [0002] Puffer fish is a species of fish that mainly inhabits the warm sea hot zone in tropical and temperate regions. Redfin Eastern Pufferfish Dark-patterned pufferfish Yellowfin pufferfish and White's pufferfish More than 6 kinds, and used for food. At present, the amount of pufferfish resources along the coast is showing a trend of sharp reduction every year ...
