Problems solved by technology

[0004] The purpose of the invention is to provide a method and device for collecting water samples in a scallop culture cage for the existing (diver diving) sampling method with high cost, low efficiency and lack of sampling technology. Low cost and high efficiency; the sampling device is simple and reasonable in structure, easy to carry for on-site investigation, can reduce the disturbance to the "micro-ecological" environment in the cage, and has a wide range of applications

Embodiment Construction

[0021] Such as figure 1 Shown, be the embodiment of the collection device of water sample in a kind of scallop breeding cage of the present invention, comprise manual vacuum pump 1, sampling pipe 6, sampling bottle 2, the rubber plug 3 on the mouth of sampling bottle 2, the rubber plug 3 penetrates The sampling tube connecting plug 4 and the vacuuming tube connecting plug 5, the manual vacuum pump 1 is closely connected with the vacuuming tube connecting plug 5 through the vacuuming tube 7, one end of the sampling tube 6 is closely connected with the sampling tube connecting plug 4, and the other end is connected through the scallop cage chassis. The hole is inserted into the cage.

[0022] Described manual vacuum pump 1 selects the NALGENE brand L222243 type that American produces, is equipped with vacuum pressure gauge, and suction filtration rate is 36cm every time, the highest can reach 635 millimeters of mercury column vacuum degree.

[0023] The sampling bottle 2 is a c...

Abstract

The invention provides a method and a device for collecting a water sample in a scallop culturing cage. The method is characterized by comprising: a sampling pipe is inserted in the cage through a hole of a base plate of the scallop cage, and is arranged in the center of the scallop cage; the other end of the sampling pipe is fixed on a buoyant raft of a culturing raft rack; sampling is started after adaption of between 3 and 5 days; one end of the sampling pipe is taken off from the buoyant raft, and is closely connected with a sampling pipe connection plug on a rubber plug of a sampling bottle mouth; a vacuumizing pipe of a manual vacuum pump is closely connected with a vacuumizing pipe connection plug on the rubber plug of the sampling bottle mouth; water in the sampling pipe is pumped and poured first, and then is vacuumized by the manual vacuum pump, so that water sucked in the sampling bottle can be taken to a laboratory for analyzing treatment after reaching a required amount. The method can collect on-site water sample without interrupting cultured creatures, thereby ensuring scientificity and effectiveness of marine ecologic environmental monitoring.

Description

technical field [0001] The invention belongs to the technical field of the collection method of ecological environment monitoring samples and the manufacturing technology of sampling equipment in aquaculture ecology, specifically a method and device for collecting water samples in scallop cultivation cages, which are used for chlorophyll, chlorophyll, Determination of physical and chemical biological environmental factors such as suspended particle concentration, microorganism and nutrient concentration, based on which analysis and research of changes in the ecological environment inside and outside the cage, and evaluation of the impact of cultured scallops and fouling organisms on the cage on the environment inside the cage. Background technique [0002] Fouling organisms in the raft farming process has become a worldwide, ubiquitous and faced problem, which has aroused widespread concern and great attention. A large number of fouling organisms attach to the cage netting, ...
