Portable sorting device for fishery catch samples

Abstract

The invention discloses a portable sorting device for catch samples. The portable sorting device comprises a sorting table; a plurality of water permeable holes are formed in the grid plate, the grid plate is detachably connected to the sorting table, and the sorting table is divided into a placing area and a plurality of sorting areas by the grid plate; the water collecting assembly is fixedly connected to the bottom end of the sorting table, a water collecting opening is formed in the middle of the sorting table in a penetrating mode, and the water collecting assembly communicates with the water collecting opening; and the flushing part comprises a water tank and a flushing assembly, the side wall of the sorting table is fixedly connected with a hoop assembly, the flushing assembly is detachably connected with the sorting table through the hoop assembly, one end of the flushing assembly is located in the water tank, and the other end of the flushing assembly is located over the containing area. The sorting efficiency of fishery resource samples can be improved, the possibility of sample omission is reduced, and the problem of insufficient sampling is avoided.

Description

technical field [0001] The invention relates to the technical field of fish catch sorting devices, in particular to a portable fish catch sample sorting device. Background technique [0002] In the survey of marine fishery resources, it is necessary to sample the fish caught by trawls into sample bags, number and record them, store them on ice, and bring them back to the laboratory for analysis and identification. After the catch is caught, it may carry silt and a small amount of seawater, which brings inconvenience to the sorting and sampling process of the catch sample. Under the existing conditions, marine fishery resource investigators only use fish frames or plastic basins on fishing boats to hold samples when sampling catches. There is a risk of incomplete sample sampling. The samples in plastic pots have seawater accumulation and silt mixed in them, which increases the difficulty of sampling. Moreover, after a certain type of samples are selected and put aside, ther...

After the catch is caught, it may carry silt and a small amount of seawater, which brings inconvenience to the sorting and sampling process of the catch sample

In the current situation, marine fishery resources investigators only use fish frames or plastic basins on fishing boats to hold samples when sampling catches. Because the sizes of the holes in the fish frames are different, the catch samples may fall, The risk of incomplete sample sampling, the samples contained in plastic basins have accumulated seawater and mixed with silt, which increases the difficulty of sampling

Moreover, after a certain type of sample is selected, there is a risk of being re-mixed, which is time-consuming and labor-intensive, and reduces the efficiency of offshore sampling work
