The utility model discloses a sealed eriocheir sinensis tissue sample collection box, apply in sample collection technical field, including box, the rear side of box is connected with the apron through the axle pin swing, the inner chamber fixed mounting of box has the deposit storehouse, the both sides of box front side all are connected with the clamping component through the axle pin swing, the clamping component includes the clamping plate, the rear side of clamping plate is fixed with apron mounting, the both sides of box and apron front side and rear side all are clamped with supplementary sealing component. When needing to increase the sealing property of the collection box sealed through the clamping component, the user unfolds the supplementary sealing component at this moment, the positioning shell in supplementary sealing component is contacted with the box, and is fixed after through bolt and box, then clamps the positioning plate and apron, fixes supplementary sealing component between box and apron through the resilience of limiting spring, to increase the sealing property of the collection box sealed through the clamping component.

The present application belongs to the technical field of biological information analysis, and particularly relates to a microsatellite marker of a temperature regulation related functional gene of Scylla paramamosain, a detection method, a kit, an analysis method, a screening method and a breeding method. Through transcriptome data analysis, the present application screens a temperature adaptability related functional gene, develops a microsatellite marker of the temperature regulation related functional gene of Scylla paramamosain, and provides polymorphic primers, establishes a technical system and a detection method for development of the microsatellite marker of the functional gene of Scylla paramamosain. The present application not only lays a foundation for Scylla paramamosain genetic diversity research, genetic map construction and evolution analysis, but also provides valuable and reliable molecular markers for breeding of fine varieties of Scylla paramamosain.

The utility model is suitable for the technical field of Eriocheir sinensis culture, and provides a Eriocheir sinensis storage and culture pool, which comprises: a storage and culture pool body for culturing Eriocheir sinensis, wherein the storage and culture pool body comprises a plurality of culture pools, and the plurality of culture pools are used for placing and culturing Eriocheir sinensis; a mounting frame fixedly mounted on the storage and culture pool body; a feeding box assembled on the mounting frame, wherein the feeding box is used for placing food for feeding Eriocheir sinensis; and a feeding mechanism assembled on the feeding box, wherein the feeding mechanism is used for feeding the food placed in the feeding box into the storage and culture pool body. The Eriocheir sinensis storage and culture pool can culture Eriocheir sinensis, and can automatically feed the cultured Eriocheir sinensis, thereby reducing the labor burden of the staff and improving the culture efficiency.

The application provides a method for improving the ecdysis rate of Eriocheir sinensis, which can significantly improve the ecdysis rate of juvenile Eriocheir sinensis, reduce the mortality surge caused by ecdysis failure, and make the sustainable cultivation of subsequent larger size fry feasible. In addition, the method of the application also has the advantages of low cost and easy popularization.

This invention discloses the development and application of a specific marker associated with the shell thickness trait of the Chinese mitten crab (Eriocheir sinensis). This molecular marker is located in Chr09 of the Chinese mitten crab genome. Esine02654 The gene region exhibits significant sequence length polymorphism: the wild type contains a 72 bp nucleotide sequence, while in the mutant, this sequence is mutated to a single base A or deleted. This invention utilizes the specific design of downstream primers located within this variant region to develop a primer pair for detecting this structural variation. Amplification using this primer pair shows a specific 109 bp band in thick-shelled individuals (wild-type), while thin-shelled individuals (homozygous deletion mutant) show no amplification band due to the absence of the primer binding site. This marker detection is simple, and the results are intuitively interpreted, showing either a band or no band, making it suitable for early-stage auxiliary screening and breeding of the thick-shell trait in Chinese mitten crabs.
