Abstract

The invention discloses a crossbreeding method for female fugu rubripes and male takifugu obscures. The method comprises the following steps: by taking female fugu rubripes and male takifugu obscureswhich are large in size and health and strong in physique as parents, putting composite vitamins for enhancing nutrition into feeds; in a breeding season, implementing an artificial spawning and fishfertilization method according to a certain ratio, and incubating in a special incubation facility; after fish fries are incubated, feeding with animal biological baits such as rotifera, artemia, cladocerans and copepods, vegetal baits such as chlorella and microorganism baits such as ocean rhodotorula to start feeding, and gradually feeding with artificial composite feeds; in a growth period of hybridized pufferfish, and breeding by using a gradual thinning method, thereby finally obtaining the hybridized pufferfish which grows at a speed which is 30% faster than that of the takifugu obscuresand is delivered to the market 3-6 months ahead. The hybridized pufferfish has meat more delicious than that of the fugu rubripes, and the taste of white juice hybridized pufferfish is approximate tothat of the takifugu obscures.

Description

Technical field [0001] The invention relates to the technical field of selection and breeding of aquaculture species, in particular to a method for cross breeding of redfin puffer female and obscured puffer male. Background technique [0002] Both redfin and obscured puffer belong to the genus Takifugu, Takifidae, and pufferfish. Redfin Takifugu mainly inhabits the warm water environment near the seabed, mainly distributed in the Bohai Sea, the Yellow Sea, the Korean Peninsula and the Sea of ​​Japan. It grows fast, is large, has good meat quality, elasticity and chewy, and is suitable for raw food. , After being cultivated, it is exported to Japan, South Korea and other countries. The domestic eating habit lies in cooked food. The processed redfin puffer has a lower taste than other fish such as obscured puffer, so domestic consumption is low. [0003] Fugu obscurus is an offshore warm-temperate bottom migratory fish. It is mainly distributed in the East China Sea, the Yellow Sea...
