Method and device for fish detection and estimation

Purpose

Minimize errors in the number of detected fish and improve accuracy in assessing its reserves.

Application

It can be used by developers to create a promising scientific hydroacoustic apparatus for estimating fish stocks.

Technical description

The amount of fish detected is corrected taking into account the coefficient of reduction of the " Couzo " field of view , depending on the speed, roll, trim, angular yaw rate and other parameters of the vessel position.

 

The patent is developed on the basis of materials from reports on research and development, results of analytical calculations, model and field experiments, which, together with application documents for registration of the invention, represent the intellectual property of the enterprise.

Multibeam scientific echo sounder for accounting of aquatic bioresources

Multibeam scientific echo sounder for accounting of aquatic bioresources

APPOINTMENT

Multibeam scientific echo sounder refers to the scientific hydroacoustic fish-searching apparatus and is designed to lizirovania water areas, searching, and counting the number of fish, determining the parameters of the individual fish and fish aggregations.

APPLICATION

Multibeam scientific sounder is used for hydroacoustic surveys of the studied waters. The results of sonar surveys are used to quantify fish stocks.

TECHNICAL SPECIFICATION

Multibeam scientific sounder provides: formation of the sector characteristics of the direction in the radiation mode and the formation of a fan of directional characteristics in the reception mode; temporary automatic gain control according to the laws of 20lgR+2aR and 40lgR+2aR for bulk scatterers and single targets; selection of echoes from the bottom surface and from single targets; calculation of THE NASc (Nautical area scattering coefficient) – the integral value of the relative biomass of fish per square nautical mile along the trajectory of the research ships; calculation and construction of a histogram of the size range (target force) of the detected single fish; display of echograms and construction of 3D images of objects in the field of view; adaptive threshold processing and other necessary functions.

Computer programs

Software module "Single target selector"

Software module "Single target selector"

APPOINTMENT

The program module for selection of single targets is designed for selection of echo signals from single targets (fish) and calculation of the true value of their target strength (TS).

APPLICATION

The software module for selection of single targets is used as part of the software of scientific sonar equipment – single-beam and multibeam sonar and sonar.

TECHNICAL SPECIFICATION

The software module for selection of single targets works in accordance with the algorithm, taking into account: the amplitude of the echo pulse, enhanced by the varu law 40lgR+2aR, with respect to the threshold value, the duration of the echo pulse within the specified limits, the deviation of the phase differences of the split beam inside the echo pulse, the spatial position of a single target in the solution of the directional characteristics relative to its acoustic axis.
