The present invention discloses a fluorescence in situ hybridization method for co-localization of multiple genes in shellfish hemocytes, belonging to the technical field of cell biology of marine invertebrates. By optimizing the osmotic pressure buffer system and the preparation method, the present invention can stably obtain a monolayer sample with complete and uniform cell morphology. By advancing the cell morphology imaging step, the complete morphological information of cells is obtained and fixed as a reference before implementing the stringent in situ hybridization process. The present invention can achieve in situ visualization of multiple target genes while better preserving the cell morphological structure, which helps to obtain more accurate and stable spatial distribution information of gene expression at the single-cell level, improves the overall reliability of the experiment, and provides a more effective analysis tool for the study of cell functions of marine invertebrates.

The present invention provides an attachment base for sessile aquatic invertebrates that improves the structure of conventional coral attachment plugs and facilitates the promotion of growth and breeding management of sessile aquatic invertebrates in general. [Solution] The attachment substrate 10 for sessile aquatic invertebrates serves as a base for attaching sessile aquatic invertebrates, and includes a frame 1, an alkaline mineral plate 2 which is a member containing alkaline minerals and is placed on and near the attachment surface to which the sessile aquatic invertebrates attach, an internal magnet 3 which is a first magnetic piece and is placed inside the alkaline mineral plate 2, and an external magnet 4 which is a fixing member. The attachment substrate 10 for sessile aquatic invertebrates is fixed onto an in-aquarium shelf 7 which is a non-magnetic object placed between the frame 1 and the external magnet 4 via the attractive force between the internal magnet 3 and the external magnet 4.

The utility model relates to a demersal invertebrate flotation device which comprises a flotation frame, an installation frame and a supporting frame, a first screen plate is arranged in a flotation cavity of the flotation frame, the flotation frame is sleeved with the first screen plate in cooperation with the installation frame, and an intercepting screen plate on the installation frame is aligned with the first screen plate. According to the screening device for the benthic invertebrates, due to the fact that the blocking net plate is arranged in the screening device, and the hole diameter of the blocking net holes is larger than that of the first screening net holes, when the benthic invertebrates are sorted, gravels and aquatic plant residues large in size can be blocked through the blocking net plate firstly, then further screening is conducted through the first screening net plate, non-target substances mixed in the benthic invertebrates can be effectively reduced, and the screening efficiency is improved. According to the benthic invertebrate collecting device, the possibility that benthic invertebrates are attached and hidden is reduced, the sorting difficulty is reduced, the sorting efficiency of the benthic invertebrates is improved, and therefore the collecting efficiency of benthic invertebrate samples is improved.
