Description

A device suitable for optimal mixed culture of japonicus, abalone and macroalgae

technical field

The invention belongs to the field of mariculture, and in particular relates to a device suitable for mixed and optimized cultivation of sea cucumbers, abalones and large seaweeds.

Background technique

Mariculture self-pollution is one of the important factors leading to eutrophication in offshore waters. In recent years, many scientific research and production practice activities have been carried out around the compound ecological breeding of sea cucumber and abalone. Sea cucumbers can remove and utilize the biological sediment produced by abalone culture, reduce the accumulation of substances and energy at the bottom of the culture area, and reduce the self-pollution of the filter-feeding shellfish culture system. Therefore, there are many studies on the polyculture of ginseng and abalone at this stage. . During the growth process, macroalgae absorb a large amount of CO ₂ , N, P and other biogenic elements, release O ₂ through photosynthesis, and synthesize and accumulate organic substances. They can be used as biofilters for polyculture with ginseng and abalone, and can reduce the nutrient load of aquaculture water. At the same time, the economic and ecological benefits of farming can be improved. However, there are few studies on the polyculture of ginseng-abalone-algae at present, and there is a lack of mature culture devices.

Detailed ways

The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

The technical scheme adopted in the utility model is as follows: a device suitable for the mixed optimized cultivation of japonicus-abalone-large seaweed, the device is hexagonal in shape and consists of a frame, a net, a sinker, a hanging rope 1 and a float ,As shown in Figure 1.

The frame of the device is composed of three layers of hexagonal plastic mesh partitions, which divide the device into upper, middle and lower layers. The upper layer 3 cultures abalone, the middle layer 4 cultures sea cucumbers, and the lower layer 5 connects sinkers. The net is connected with the frame to form a net cage, the upper end of the net is connected with a suspension rope, and the upper end of the suspension rope is connected with a float, and the function of the float and the sinker is to fully expand the whole device. The material of described netting adopts polyethylene rope net, and mesh is 1.5cm.

The mesh partition between the upper strata 3 and the middle layer 4 is the first partition, and the first partition includes a hexagonal tapered mesh funnel plate 11 and a hexagonal mesh flat plate 12, as shown in Figure 2, the The six sides of the hexagonal mesh flat plate are respectively connected to the hypotenuses of the funnel plate, and the horizontal distance between the joint and the mesh cage is 5-10 cm, and the joint is provided with a plurality of mesh holes, and the mesh is 0.5-0.8 cm. Described hexagonal mesh flat plate plays the effect of supporting abalone, and as shown in Figure 3, mesh is 1-1.5cm, and mesh is smaller than the specification of abalone fry, prevents abalone fry from falling into funnel plate. The mesh of the hexagonal tapered mesh funnel plate is 0.5-0.8cm, which is convenient for the biological sediment of abalone to fall into the middle layer. When the biological sediment produced by the abalone attached to the net and the flat plate falls down to the funnel plate, the funnel plate generates a downward sliding force on it, and falls to the spine through the mesh of the funnel plate during the downward sliding process. The ginseng breeding layer is used for the consumption of sea cucumbers. Therefore, the function of the hexagonal conical mesh funnel plate is to gather the biological deposits of abalone, prevent the biological deposits from being taken out of the cage due to the lateral flow of seawater, and reduce the The utilization rate of sea cucumber to biological sediment is not conducive to improving the problem of marine pollution.

The present invention also includes a seedling curtain 2 for seaweed to attach to and grow. As shown in Figure 4, the seedling curtain is a rectangular curtain-like structure as a whole, and the upper edge and the lower edge of the seedling curtain are connected with a lock 6, and the seedling curtain after the seedlings are picked It is fixed to the outer side of the net cage with locks for easy removal. The hexagonal column shape of this device can be used to hang seedling curtains on the outside. It is preferable to set seedling curtains on three sides of the hexagonal columnar surface to ensure sufficient transparency Light, provide enough food for sea cucumber and abalone.

The device has good light transmittance, adds a device for hanging algae, has low input cost, and is easy to popularize. The mesh funnel plate set between the abalone culture layer and the sea cucumber culture layer can play a role in the accumulation of the biological sediment of the abalone, improve the utilization rate of the biological sediment by the sea cucumber, and help to improve the problem of marine pollution. Due to the proliferation of large algae, the whole breeding process does not need to be fed, and because the seaweed blocks the algae and floating mud, the breeding cage can be kept clean for a long time, which can greatly reduce or eliminate the labor intensity of washing the breeding cage. Therefore, the cost of human resources is reduced, and the invention has good popularization and application value.

Fix the seedling curtain after picking seedlings to the outer side of the culture cage with locks, put 50-60 grains of abalone seedlings (size 2-3cm/ grain) on the upper layer of the culture cage, and put 10-20 sea cucumber seedlings (size 4 -5cm/head) for polyculture. Sea rafts are used for hanging culture, and buoys are used as floats. Sea culture is selected in coastal sea areas with small wind and waves, smooth tide, fertile water quality and transparency of 1-3m. The distance between two adjacent cages is about 3m. Regularly clean the culture equipment to remove harmful algae, oysters, barnacles and other harmful organisms attached to the seedling curtains, cages and abalone shells. If individual dead individuals are found, they should be fished out in time, and moved to land for treatment, and not thrown into the breeding area to avoid cross-contamination.

The above embodiment is only one of several preferred implementation modes of the present invention. It should be pointed out that the present invention is not limited to the above embodiment; Modifications, or equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed in the present invention.
