Description
Technical Field
The invention relates to sea cucumber cultivation, in particular to a sea cucumber seabed cultivation net cage.
Background
We know that sea cucumber belongs to echinoderm, which is the first of eight delicacies with famous seafood, is rich in nutrition and has high edible value and medical value. With the improvement of living standard of people and the continuous reduction of natural sea cucumber resources, the yield of wild sea cucumbers is difficult to meet the requirements of people, and the industry of artificial sea cucumber culture is developed. The traditional sea cucumber culture modes mainly comprise pond culture, tidal stream cofferdam culture, shallow sea cage culture, factory greenhouse culture and the like, and the traditional sea cucumber culture modes artificially reform the growth environment of the sea cucumbers and influence the quality of the sea cucumbers. Because the natural baits such as organic detritus and phytoplankton on the seabed are sufficient, the quality of the sea cucumber cultured on the seabed is closer to the quality of the sea cucumber cultured on natural growth, in recent years, the sea cucumber culture is greatly developed to the sea-bottom net cage culture, and the majority of technical personnel invent the net cage suitable for the sea cucumber cultured on the seabed. For example, CN202077482U chinese utility model patent specification issued 11/21/2011 discloses a multifunctional sea cucumber ecological net cage, which comprises a plurality of buoys, wherein each buoy is connected in sequence through a connecting piece, an upper cross bar and a lower cross bar to form a regular polygonal net cage frame, an outer netting is laid outside the net cage buoy, three layers of nettings are laid on the upper side of the upper cross bar, the lower cross bar and the cross bar respectively, and each netting takes the buoy, the upper cross bar, the lower cross bar and the cross bar as a framework to form a regular polyhedral double-layer net cage; the bottom of each buoy is fixedly provided with an iron casting which is arranged on the anchoring net cage. For another example, the 2015 year 22/4/22 granted announcement CN204272932U patent specification of the chinese utility model discloses a lifting type sea cucumber culturing device, the net cage support frame of the sea cucumber culturing device comprises an upper layer support frame, a lower layer support frame and a connecting frame, and two ends of the connecting frame are respectively connected with the upper layer support frame and the lower layer support frame through a three-way pipe; hollow tubular units which are also used as floating cylinders are arranged in the upper layer support frame and the lower layer support frame, and one-way valves are arranged at the joints of the adjacent tubular units; the netting is fixed between the upper and lower support frames, a plurality of holothurian culture rooms are arranged in the netting, the upper end of each holothurian culture room is connected with the upper support frame, and the lower end of each holothurian culture room is connected with the netting; supporting legs which are also used as weights are arranged below the lower layer supporting frame. The net cage support frame related in the patent documents can only play a role in supporting the netting and providing a three-dimensional culture space for the sea cucumbers; the bottom of the net cage is directly contacted with the sea bottom surface by iron castings or supporting legs, and the net cage is anchored and supported. Although the bottom netting of the net cage with the structure can avoid direct contact with the sea bottom and scratching the netting, the bottom of the net cage is far away from the sea bottom, and the seabed silt mixed with micro organisms can only be driven by the wave current of the sea water to enter the inside of the net cage, so that natural bait is provided for the sea cucumbers. In a sea area with a gentle sea wave flow, sea sediment mixed with micro organisms brought by sea water only flows through the lower bottom of the net cage, natural baits flowing through the middle upper part of the net cage are few, and therefore the natural baits of the sea cucumbers in the net cage are not supplied uniformly, and the growth of the sea cucumbers is influenced.
