The invention discloses a parent swimming crab breeding method. The parent swimming crab breeding method comprises the steps of selecting healthy parent crabs and arranging a parent crab breeding room; adjusting the temperature of the breeding room; disinfecting the parent crabs; putting the parent crabs into the parent crab breeding room to be bred; disinfecting the parent crab breeding room for one time every day; breeding male crabs and female crabs for 20 days in a separated mode and then transferring the male crabs and female crabs to a copulation pond to be bred for 10-12 days till the female crabs are fertilized. By adopting the parent swimming crab breeding method, the parent crab survival rate is high, the parent crab physique is obviously strengthened, the fertilization rate of the female crabs in the parent crabs is improved, the fertilized ovum survival rate is improved, and the survival rate of young crabs developed from fertilized ovum is improved.

The invention relates to a juvenile crab cultivating method for high-sea swimming crabs. The juvenile crab cultivating method comprises the steps of selecting parent crabs, preparing a storage pond, managing non-egg-carrying crabs, managing egg-carrying crabs and cultivating juvenile crabs. According to the juvenile crab cultivating method for the high-sea swimming crabs, the manual juvenile crab cultivating technology study for the high-sea swimming crabs is carried out for increasing an excellent new cultivation product in Guangxi, and the method plays an important role in promoting the breed structure adjustment of sea farming industries and developing the ocean economy.

The invention relates to a portunus pelagicus polymorphic microsatellite molecular marker, an identification method and application. The identification method comprises the following steps: portunus pelagicus genomic DNA (Deoxyribonucleic Acid) extraction, simplified genomic library construction and high-throughput sequencing, sequence analysis and microsatellite primer designing, and microsatellite marker polymorphism evaluation. According to the identification method disclosed by the invention, 17983 microsatellite loci are identified, and 16 microsatellite markers having molecular polymorphism are screened out. The identification method disclosed by the invention has the advantages that the operation is simple and safe, the accuracy is high, a result is true and reliable, and the like,and is capable of being used for quickly and massively obtaining portunus pelagicus microsatellite markers; the technical method disclosed by the invention can be widely applied to numerous species having no reference genome because of no need to know genomic information in advance, and has a wide popularization and application potential; in addition, a candidate tool can be provided for population genetic variation evaluation, genetic relationship identification and genetic linkage map construction of portunus pelagicus by 16 pairs of polymorphic microsatellite marker primers obtained by themethod.

The present invention belongs to the technical field of food processing and discloses seafood flavored braising juice. The braising juice is prepared by boiling main materials of portunus pelagicus, dried scallops, dried cuttlefish, razor clams, dried shrimps, crucian carps, chicken bones and back bones. The prepared seafood flavored braising juice is rigorous in material selecting, scientific and reasonable in formula matching, combines requirements in aspects of nutrition, taste, color and luster, etc., is rich in taste levels, satisfies people's pursuit of delicious taste of seafood, also has certain health-care functions of nourishing body and caring health, and can also grant a seafood taste and a special mellow taste of stewing dish even be applied in originally tasteless cooking raw materials. The seafood flavored braising juice is greatly simplified in processing processes on technologies, conforms to development of modern catering industries and has relatively great application prospects.

The invention relates to a method for efficiently breeding blue crabs. The method comprises the following steps: performing intermediate breeding on II-stage baby blue crabs in an outdoor cement pit greenhouse; disinfecting the water for breeding through an ultraviolet lamp and mounting an oxygenating device in a breeding pond; feeding big disinfected brine shrimps at regular time; exchanging 15% water per day; after the II-stage baby blue crabs grow and become V-stage baby blue crabs, putting juvenile crabs into the breeding pond at a sex ratio of female to male being 3:1; after ending mating, fishing out the male crabs; continuously breeding the female crabs; and when the water temperature is lower than 10 DEG C, putting the female crabs into the outdoor cement pit greenhouse for temporarily breeding and putting into the market before and after the Spring Festival, thereby greatly increasing the breeding yield and economic benefit. According to the method provided by the invention, the juvenile crabs are prevented from being killed by enemies and severe environment; the use ratio of baits is increased and the happening of diseases is reduced; the breeding yield of the blue crabs is increased by 26.99% and the breeding benefit is increased by 2.39 times, by adopting the method provided by the invention; the method can be widely applied to the breeding for the blue crabs; the energy conservation and the environment protection are realized; and the economic benefit and the social benefit are obvious.
