Description
Technical Field
The utility model relates to the technical field of marine organism screening, in particular to spraying and screening equipment for marine benthos.
Background
Benthic organisms refer to organisms that live on the surface of a substrate or in sediments, and these organisms live from the intertidal zone to the ultra-deep-sea-level zone (deep-sea ditch bottom) of the ocean with a depth of more than ten thousand meters, and are one of the most diverse types of ecotypes of marine organisms, including most of the phyla of marine animals, large-sized seaweeds, and marine seed plants. The marine benthos has various species, wherein the number of benthos is small, and the benthos has various species and structures. According to biological attributes, the marine benthic plants and marine benthic animals can be divided; according to the nutritional type, the marine benthos can be divided into autotrophic marine benthos and heterotrophic marine benthos. Marine benthos are classified into 3 types according to the size of body form: (1) large benthos, with a length (diameter) greater than 1mm, such as sponges, corals, shrimps, crabs, and hairy species; (2) the small benthos has the body length (diameter) of 0.5-1 mm and mainly comprises marine nematodes, marine crustacean fleas, mesogens, kisses and the like; (3) the diameter of the micro benthos is less than 0.5 mm, and the micro benthos mainly comprises marine protozoa and bacteria. In marine ecosystems, benthos are in different levels of nutrition, respectively. Benthic plants are producers, at the first stage of the food chain. Some of the phytophagous benthonic animals feed on macroalgae, such as algal shrimps and abalones; some feed on phytoplankton or organic debris, which are in the second order in the food chain, such as bivalves, acete chinensis, copepods, etc. Many carnivorous benthic species feed on phytophagous zooplankton and benthic animals, and belong to the third stage of the food chain, such as snails and many shrimps, crabs. Some benthonic animals are objects for human consumption, such as commercial shrimps, crabs, shellfish and some benthonic fish; some species are fish and other animal prey objects, such as shrimps, crabs, shellfish, and hairy species. Therefore, the method has important significance in explaining the quantity change rule of benthos and the relation between the benthos and the productivity and resources of marine organisms.
The benthic organism community is investigated by the shallow water direct observation counting method (shallow water), mud sampler/box sampler, bottom trawl and sampling frame method (intertidal zone). Wherein the benthic organism survey of marine shallow sea sediments comprises: the area of mud collected at each station is not less than 0.2m2The organisms, including the biological residues, after the mud-like elutriation are collected completely. The sampling instrument comprises a grab bucket mud sampler, a spring mud sampler, a box mud sampler, a columnar mud sampler and the like. The device is a special device for elutriating mud samples and separating samples, which consists of a barrel, a vortex generator, a flow divider, a bracket and a residue collecting tray, and consists of three layers of sieves with different apertures and the bracket, wherein the aperture of an upper layer of sieve is 2-5mm, the aperture of a middle layer of sieve is 1mm, and the aperture of a lower layer of sieve is 0.5 mm, and the device must be matched with the vortex separation device for use. The device is relatively complicated to operate during the voyage survey, and is not easy to operate under the condition of poor sea condition or large wind waves. Therefore, it is urgently needed to develop a marine benthos spraying and screening device to solve the technical problems.
In view of the above, the present invention is particularly proposed.
