Abstract

The invention relates to a cage culture biomass monitoring acoustic system and method. According to the system and method, a free moving platform, an underwater sound transducer and a transceiver control device are installed in a net cage and are connected with a data processing system. Sound wave signals are transmitted to the net cage, sound scattering signals of fish in the net cage are received by the transceiver control device, sound scattering target strength of the fish is measured and processed by means of the data processing system, and the size, quality, density and total biomass of the fish in the net cage are detected by means of the system and method.

Description

technical field [0001] The invention relates to an acoustic monitoring system and method for monitoring the quantity of biological resources in cage culture, and in particular to a system and method for measuring and monitoring the size, quantity of biological groups and the total amount of resources of cage culture organisms. Background technique [0002] For fish farmers, it is very necessary to timely and accurately estimate the size, quantity and total biomass of the cultured organisms (such as fish) in the cage. . Cost savings and increased profits have a greater impact. [0003] Generally speaking, aquaculture enterprises put "deep-water cages" in the sea or lakes and sink them into the water. Usually, the cages are woven with plastic skeleton and mesh materials to prevent the escape of the cultured organisms in the cages. , and can maintain the water circulation in the cage, so as to ensure the delicious taste of the cultured organisms. [0004] For fish farming en...
