Portable freshwater aquaculture transparency detector

Abstract

The invention provides a portable freshwater aquaculture transparency detector, comprising a floater and a rod disposed below the floater. The floater is provided with a lifting device used to conveniently lift up and down, the rod is provided with a scale, the rod is sleeved with an marker plate I, a marker plate II and a marker plate III respectively at 30 cm, 40 cm and 50 cm below the floater, the size of the marker plate I, the marker plate II and the marker plate III gradually increases, and the marker plate I, the marker plate II and the marker plate III are provided with markers used to distinguish 30 cm, 40 cm and 50 cm. The portable freshwater aquaculture transparency detector is convenient to carry along, and may be placed optionally at a corner of culture water or in the center of the water to, in either case, enable accurate detection for the content of planktonic microorganisms in the culture water, namely culture water transparency, facilitating timely mastering of the quality of the culture water, helping a farmer to decide how to adjust the water quality and implementing scientific cultivation.

Description

technical field [0001] The invention belongs to the technical field of researching or analyzing materials by using a special method not included in the groups G01N1 / 00 to G01N31 / 00, in particular to a portable freshwater aquaculture transparency detector. Background technique [0002] The aquaculture industry is a technically complex system industry, from the optimal cultivation of aquatic fish, hatching, fish seedling cultivation, adult fish breeding, water quality regulation, disease prevention, market sales and other links; involving 100 types of aquatic products, quality From low-end to high-end, demand from small to large, aquaculture technology and production have also been greatly improved. Among them, the content of planktonic microorganisms in the aquaculture water is the decisive factor that determines the degree of transparency, and it is also to ensure the healthy growth of aquatic products, improve quality and Yield is an extremely important link; after many yea...

[0002] The aquaculture industry is a technically complex system industry, from the optimal cultivation of aquatic fish, hatching, fish seedling cultivation, adult fish breeding, water quality regulation, disease prevention, market sales and other links; involving 100 types of aquatic products, quality From low-end to high-end, demand from small to large, aquaculture technology and production have also been greatly improved. Among them, the content of planktonic microorganisms in the aquaculture water is the decisive factor that determines the degree of transparency, and it is also to ensure the healthy growth of aquatic products, improve quality and Yield is an extremely important link; after many years of experience in freshwater aquaculture, in terms of aquaculture transparency testing, there are only aquaculture requirements of 30-50 cm transparency in the technical data of various varieties of aquaculture. If the transparency is less than 30, the water quality will deteriorate. It is conducive to the growth of fish, the transparency is greater than 50, and there will be no fish when the water is clear. It is also not conducive to the growth of fish. How to detect it and what instrument is used to measure and control the amount of plankton in the aquaculture water with scientific and accurate data, How to detect the transparency of aquaculture water and how to provide a reference for the healthy growth of aquatic products microenvironment is a vacancy. The existing detection methods are estimated by naked eyes or traditional rulers. Due to the difference in the refraction principle of light and water quality, The transparency data that leads to reading is actually discrepant
