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 present invention relates to a hybrid between puffer obscurus (OLIVE TAKIFUGU OBSCURUS) and puffer red fin (TAKIFUGU RUBRIPES) and a hybridization method thereof, more specifically, puffer obscura and puffer red fin A hybrid between them and a production method, which include extracting eggs and semen from a female of puffer obscurus and a male of puffer red fin respectively, and carrying out artificial insemination between them to obtain fertilized eggs, hatching the fertilized eggs and The step of breeding is carried out so that a cultured species with a rapid growth rate can be produced. Background technique [0002] Pufferfish is a species of fish mainly inhabiting warm seas in tropical and temperate regions. It is fished in Korea such as Chinese pufferfish. Redfin Pufferfish Fugu obscurus Yellowfin pufferfish and White's Largopus And so on more than 6 kinds, and used for food. At present, the amount of puffer fish resources along th...
