Problems solved by technology

[0003] However, the artificial breeding method of cage culture of fish faces the difficulty of monitoring. Due to the limited transparency of the water, the cultured fish in the cage cannot be seen. In order to prevent the fish from escaping from the broken net, it takes a few days to change the net, and most fish like to eat at night, which requires a lot of labor

Abstract

The invention discloses an ultrasonic monitor device of net cage fish culture biomass evaluation. An ultrasonic transducer emits ultrasonic probe pulse signals to cultured fishes in a net cage and receives reflection ultrasonic pulse signals of the cultured fishes in the net cage; and the reflection ultrasonic pulse signals are processed through an ultrasonic transceiver and a signal processing device, therefore, the invention realizes real-time monitor to a water range in the net cage, reflects the condition of the cultured fishes in the net cage, carries out biomass evaluation, displays a treatment result through a display device and realizes the purpose of the invention.

Description

technical field [0001] The invention relates to an ultrasonic monitoring device, in particular to a device for monitoring the dynamics of fish in net cages and the growth of biomass by ultrasonic waves, which is used for the dynamics of fish cultured in net cages in oceans and lakes and the total amount of fish cultured in net cages. Evaluation of Ultrasonic Monitoring Devices for Biomass Assessment in Cage Fish Culture. Background technique [0002] At present, the inland lakes of our country and the coastal areas from south to north are carrying out cage culture of various economic fish, such as black squid, golden pomfret, yellow croaker, sturgeon, etc., which have high nutritional value and delicious taste. Markets at home and abroad are welcome, and cage culture of various fish has been carried out throughout the country. [0003] However, the artificial breeding method of cage culture of fish faces the difficulty of monitoring. Due to the limited transparency of the w...
