A purse seine, a support rod and a pile foundation are included, the bottom of the support rod is connected with the pile foundation, a fixing support is connected to the top end of the support rod, a groove is formed under the support rod, and the purse seine is connected with the support rod and the groove separately and connected with the groove through an expansion block; the bottom end of the support rod is provided with a hemisphere, the surface of the support rod is provided with a round convex block, the bottom end of the support rod is connected with the pile foundation through concrete pouring, the surface of the support rod is provided with a seine tying ring, and the purse seine is connected with the support rod through the seine tying ring. Groove excavating is conducted under the support rod to form the groove with the certain depth and width, then the purse seine is filled with the prepared expansion block for fixing, therefore, it is guaranteed that fixation between the purse seine and a seashore is effective for a long time, the fixing effect is obviously improved and is excellent, and an anti-escape effect is achieved and is excellent. According to the technique, implementation is easy, the structure is stable, a netting is not prone to be damaged, the fixing equipment is resistant to corrosion, and the aquaculture safety and the escape resistance are high.

Pipeline layout system for snorkeling aquaculture net cage and operation ship
PendingCN109937936AAvoid kinksReduce damage rateWaterborne vesselsClimate change adaptationTechnical supportAquaculture engineering
The invention relates to a pipeline layout system for a snorkeling aquaculture net cage and an operation ship, and belongs to the technical field of fishery aquaculture. The pipeline layout system comprises a pipeline integration structure module and an integrated pipeline layout module; the pipeline integration structure module is used for packaging and integrating a bait pipe, an air pipe and adead fish recovery pipe into an integrated pipeline; the integrated pipeline layout module is used for laying the integrated pipeline in three sections including an aquaculture net cage end movable pipeline, a fixed section pipeline and an operation ship end movable pipeline; the fixed section pipeline is positioned between the aquaculture net cage end movable pipeline and the operation ship end movable pipeline; the layout direction of the integrated pipeline is parallel to the direction of an aquaculture net cage positioning anchor chain pointing to the operation ship, and the aquaculture net cage end movable pipeline is laid in an 'S'-shaped manner. By the aid of a pipeline integration structure, kinking of the pipeline can be effectively avoided, the problems of easiness in kinking andpoor functionality of an aquaculture net cage external pipeline under severe wind wave conditions of deep sea are solved by sectioned layout, and good technical support is provided for deep-area aquaculture engineering.

The invention belongs to the field of aquaculture engineering and specifically relates to a substratum for producing oyster monomer fries and a fry collection device matched with the substratum. A substratum monomer consists of a support rod and a strip-shaped black rubber cloth suspended on the support rod, wherein the density of the strip-shaped black rubber cloth is about 1.4g / cm<3>, the strip-shaped black rubber cloth has sinking characteristics, and a stretch rate of the strip-shaped black rubber cloth is larger than 4.5. According to the substratum for producing the oyster monomer fries and the fry collection device matched with the substratum, production of the oyster monomer fries does not depend on abnormal induced drugs, fry collection facilities can be all recycled, and any damages are hardly produced during fry stripping.
