The invention relates to a vertical kelp seedling clamping machine. The design of the vertical structure is more reasonable, which effectively avoids or reduces the incidence of seedling shedding and injury; it is powered by a pneumatic device, and the claws controlled by the compression cylinder and the compression rod work together to realize the loosening of the seedling rope. In order to manually insert seedlings; the pressing cylinder cooperates with the walking cylinder to complete the descending of the seedling rope, thereby realizing continuous operation in a cycle. The transmission device that moves intermittently with the seedling rope realizes the timely delivery of the seedling rope after the seedlings are clamped, avoids damage to the kelp seedlings, and reduces unnecessary losses. Compared with the prior art, the present invention has high efficiency, safety, reliable performance, scientific design and strong practicability, and will have a broad market space in today's kelp breeding industry in the ascendant.

The invention belongs to the technical field of seaweed cultivation, and relates to a seaweed cultivation method. Natural seawater is contained in a seawater tank, and the temperature and the ultraviolet lamp irradiation are controlled to conduct disinfection treatment for standby application; selected and collected seed seaweeds are washed, disinfected and dried, then conventional culture media are selected according to different seaweed types, temperature control and dim-light static cultivation are carried out, and then enzymolysis or direct cultivation is carried out; after to-be-cultivated somatic cells, to-be-cultivated gametophytes or to-be-cultivated callus mature, bolting-silk filtering, sectioning processing and / or centrifugal collecting are carried out, the somatic cells, the gametophytes or the callus are placed into the culture media according to the requirements of different kinds of seaweeds, the temperature, the illumination and the osmotic pressure are controlled for cultivation, and the somatic cells, the gametophytes / sporophores and the callus of the seed seaweeds are attached to the silk net faces in the culture media; silk nets are then manually scattered into the offshore or the tidal zone to conduct conventional seawater cultivation. The seaweed cultivation method is simple in technology, low in cost, convenient to operate, short in seedling growing time, good in cultivation effect and high in cultivation yield, and manpower is saved.

The invention relates to a three-dimensional cofferdam culture method for ginatesargassum kjellmanianum and sea cucumbers, and belongs to the field of aquaculture. For solving a plurality of problems such as water body eutrophication, low dissolved oxygen content, high illumination and bad bottom substrates which exist in the traditional single culture variety culturing process, a three-dimensional cofferdam culture method for the ginatesargassum kjellmanianum and the sea cucumbers is established by integrating the technical advantages of seaweed culturing and the technical advantages of sea cucumber culturing and learning from each other. The method comprises the steps of cofferdam building, culture environment adjusting, fry putting, culture managing, product harvesting and the like. Related experiments show that polyculture of the ginatesargassum kjellmanianum and the sea cucumbers is beneficial for improving the culture water body environment, improving the culture quality of the sea cucumbers, increasing the yield of the sea cucumbers and transforming from a traditional extensive aquaculture mode to an intensive aquaculture mode.
