Description
Technical Field
The utility model relates to a coral reef area bottom zooplankton traps collection system utilizes purpose-made bottom zooplankton to trap the collection to bottom zooplankton.
Background
The coral reef ecosystem is one of marine ecosystems with extremely high biodiversity and primary productivity, and provides excellent habitat and food resources for various organisms. Abundant bottom layer zooplankton resources in the coral reef ecosystem play an important role in material circulation and energy transfer of the coral reef ecosystem. The small bottom layer zooplankton is used as a secondary consumer, which is a main transmitter of primary producers to the upper nutrition level, the feeding selectivity of the small bottom layer zooplankton to different foods determines the efficiency and the scale of primary production transmission to a certain extent, and plays a key role in the basic production process of the whole ecosystem. Meanwhile, the small-sized bottom layer zooplankton is the high-quality biological bait of the coral reef fishes, and the community structure of the small-sized bottom layer zooplankton influences the community structure of the large-sized bottom layer zooplankton. Therefore, the research on the feeding ecology of the small-sized bottom layer zooplankton is beneficial to understanding the current situations of material circulation and energy transfer in the coral reef ecosystem and evaluating the health and the function of the coral reef ecosystem.
The premise of understanding the feeding ecology of small and medium-sized bottom zooplankton in the coral reef ecosystem is to obtain pure and sufficient small-sized bottom zooplankton samples. Traditional sampling of zooplankton in the bottom layer can be mainly carried out by a direct trawl (vertical trawl or inclined trawl) and a sediment collection mode. Wherein the direct trawl net can only obtain the biological samples from the surface layer to the bottom layer, and the trawl net process may cause the damage of coral, the damage and the loss of net tools, and simultaneously causes the loss of small-sized bottom layer zooplankton samples inhabiting in gaps of coral. More of the organisms living in the sediment are obtained by collecting the sediment, and more sediment is generally required to obtain enough small-sized bottom zooplankton. Due to the limitation of the application of the traditional sampling method in a complex coral reef ecosystem, enough pure bottom layer zooplankton samples cannot be collected. Therefore, the composition, the living rhythm and the ingestion condition of bottom layer zooplankton in the coral reef ecosystem, particularly the species composition, the living rhythm and the ingestion condition of the small bottom layer zooplankton in the bottom stream are not clear, the status and the function of the zooplankton in the ecosystem are not clear, and the explanation of the ecological function of the small bottom layer zooplankton in the coral reef ecosystem and the evaluation of the health and the function of the coral reef ecosystem are not facilitated.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the device for trapping and collecting zooplankton on the bottom layer of the coral reef area comprises an upper net bag 10 and a lower net bag 20.
Go up string bag 10 and include the narrow-down wide frame 11 in top that comprises the plastic support, and cover in netting 13 on the frame, be provided with collection mouth 12 that can open or closed on the netting 13, be provided with zip fastener 121 on the collection mouth, open zip fastener 121 when needing to gather the sample, can pull zip fastener 121 when the collection finishes on, prevent that zooplankton from gathering mouthful wandering out. When the sample is collected at night, the netting 13 is covered with the black yarn, the black yarn is tied on the bracket in a slipknot mode and covers the netting, and the black yarn is detached when the sample is collected in the daytime.
The frame 11 is a quadrangular pyramid frame and is composed of 8 plastic supports, wherein 4 supports are used as the bottom edge of a square, and the other 4 supports are used as the edge to jointly form a quadrangular pyramid structure. The four bottom corners of the quadrangular pyramid frame are respectively provided with a slipknot 14.
The lower net bag 20 is a net bag without a support and is seamlessly connected with the netting 13 of the upper net bag 10 to form a complete net bag. When the device is placed on the seabed, the lower string bag 20 is folded to be placed on the bottom.
The lower end of the lower string bag 20 is detachably connected with a collecting device.
In this embodiment, the collecting device includes a collecting bottle 30, a bottle cap 31 is disposed at the bottom of the collecting bottle 30, the collected sample is collected in the collecting bottle 30, the bottle cap 31 can be opened to pour the sample into another container, or the collecting bottle 30 can be removed integrally to collect the sample.
Another structure form of the collecting device can be as follows: adopt the net bottom tube of marine organism net as collection device, the non-central point of lower terminal surface of net bottom tube puts and is provided with the breach, and lower terminal surface is covered with the bottom, and the position that corresponds on the bottom is provided with the same breach, and rotatory bottom can make two breachs coincidence or stagger to open or close the breach, when needs collect biological sample, rotatable bottom opens the breach, pours the bottom zooplankton sample of collecting into in other containers.
