The healthy sustainable development of fishery depends on healthy sustainable water area resources, and good fishery ecological environment is of great importance to fishery development. With the continuous improvement of economic construction and living standard in China, the influence of living and production activities of people on ecological environment is increasingly serious. The fishery ecological environment and the quality and safety of aquatic products are seriously threatened by the discharge of aquaculture activities, industry and domestic sewage, the ecological environment pollution not only causes great loss in ecology and economy, but also can cause the reduction of the yield and the quality of the aquatic products, and the food quality safety of people is seriously influenced. Under the new era, new tasks such as structural reform of agricultural supply side, transformation and upgrade of industry, ecological civilization construction, new and old kinetic energy conversion and the like put forward higher requirements on fishery development.
The bottom mud is usually a mixture of clay, silt, organic matters and various mineral substances and is formed by depositing on the bottom of a water body through long-time physical, chemical and water body transmission actions and the like. The sediment pollutant mainly comes from bait feeding, fertilization and exogenous water pollution etc. and is great to the influence of water environmental quality, and the pollutant exchanges between water and sediment, and when the volume of pollutant was many in the water, the pollutant can be adsorbed by the sediment, and when the volume of pollutant was few in the water, adsorbed pollutant in the sediment will release the aquatic again. In order to research the accumulation, distribution, transformation, migration and other rules of the sediment pollutants, ecological restoration or water regulation and control technology and improve the quality and safety of aquatic products, sediment samples need to be collected for analysis and research. Current sludge sampler is mostly "luoyang shovel" that similar archaeology was used, and its structure only is fit for the land sample, and current sludge sampler inserts submarine silt, and the silt in the sludge sampler can not normally be taken out when extracting, is unsuitable to gather submarine silt.

The columnar layered mud sampler is characterized in that a glass sampling tube is additionally arranged in an elastic opening tube shovel, a piston cover and a conical one-way valve are additionally arranged on the glass sampling tube, and a smooth hollow ball is arranged in the conical one-way valve. In the process of inserting the mud sampler into the underwater mud, the conical one-way valve is automatically closed, when the mud sampler is pulled out, the mud is taken out of the water along with the glass sampling tube, and samples in the glass sampling tube can be extruded layer by utilizing the piston cover.
