Digitized monitoring method for Chinese sturgeon natural reserve

Abstract

The invention discloses a digitized monitoring method for a Chinese sturgeon natural reserve, belonging to an aquatic animal monitoring method which aims to solve the problems of data storage marks, underwater base station receiving and wireless transmission. The method has the technical scheme that acoustic marks, wireless marks and integrated passive repeater marks are adopted to singly mark ormultiply mark young Chinese sturgeons. The method is characterized in that the center of the reserve is used as a base point; fixed float bowls are arranged every 7km in the north-south direction, andeach float bowl is provided with a sonar signal receiving device; the signal receiving in the north-south direction covers a water area of about 60km wide; the sonar receiving device is used for receiving, and data signals are amplified and transmitted to a base station on land in a wireless transmission mode; a young Chinese sturgeon reserve is provided with 4-7 environment monitoring stations,and on-line water quality monitoring equipment is utilized to monitor the conditions of the hydrology, the meteorology, the water quality, and the like in real time; and obtained information is transmitted back to the base station in the wireless transmission mode. The method is used for Chinese sturgeon monitoring.

Description

Technical field: [0001] The invention relates to a digital monitoring method for aquatic animal nature reserves. Background technique [0002] The Chinese sturgeon is a rare and endangered fish endemic to rivers and seas in my country. It is a national key first-class wildlife protection animal. It is only distributed in the coastal waters of China and the main stream of the Yangtze River. Sexually mature individuals travel upstream from the ocean to the upper and middle reaches of the Yangtze River to spawn and reproduce. The juveniles swim downstream And then feed and fatten from fresh water to sea water. The Yangtze Estuary is the only channel for the upstream migration of Chinese sturgeon broodstock and the downward migration of juvenile fish. In 2002, the Shanghai Municipal People's Government established the "Shanghai Yangtze River Estuary Chinese Sturgeon Nature Reserve", which is located in Dongtan, Chongming, with a water area of ​​276 square kilometers. From May t...

Problems solved by technology

This method has a large workload, poor timeliness, and is more affected by weather conditions, so there are many shortcomings.

Internationally, fish marker tracking technology has developed rapidly, but most of them use single marker method, small-scale and short-term tracking research

A recent new product—Archival Pop-up Tag technology (Archival Pop-up Tag), which can record a large amount of information related to fish migration behavior and the environment, but the performance of this product is currently unstable, especially when data needs to be recovered through satellites. The operation is complicated and the operating cost is high. The key point is that this product is too large to be suitable for Chinese sturgeon juveniles

The single fish marking technology and data transmission technology are already very mature, but according to the characteristics of the Yangtze River Estuary Chinese Sturgeon Reserve and the particularity of the research object, the method of assembling and integrating these technologies as research methods to meet the research needs is currently No report
