Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of fishing, and is intended for diagnostics of aquatic organisms (detection, location and movement, the species, age, sex and condition). Essence: using the measurements of the temperature field of the water area under study and echolocation based on the previously determined empirical relationships aquatic organisms behavior (preference for certain parameters of habitat, movement speed, characteristic movements depending on the species, age, sex and condition) on the temperature the presence and location of aquatic organisms is determined, and also their age, sex and condition.

EFFECT: determining not only the presence and location but also the type, age, sex and condition of aquatic organisms: fish and other aquaculture objects.

Description

FIELD OF THE INVENTION

The invention relates to the field of fishing and is intended for the diagnosis of aquatic organisms (detection, location and movement, species, age, gender and condition).

The invention is also relevant in the field of breeding of aquatic organisms: fish and other aquaculture objects for the intermediate control of their breeding parameters.

State of the art

Known ″ Method of direction finding of hydrobionts and a device for its implementation ″, see RF patent No. 2064683 [1], which suggests direction finding of hydrobionts through noise-protected channels.

The disadvantage of this method: the inability to distinguish between species, age, gender and state of aquatic organisms, as well as restrictions on distance.

The known ″ Method of direction finding of aquatic organisms and a device for its implementation ″, see RF patent No. 2093856 [2], which proposes to determine the parameters of aquatic organisms and classify them according to spatial-frequency analysis of hydroacoustic signals.

The disadvantage of this method: the loss of accuracy of identification with distance, difficulties in determining the age, gender and condition of aquatic organisms.

The known approach described in the patent of the Russian Federation No. 2154286 ″ Device for the detection and direction finding of hydroacoustic radiation of marine biological objects ″ [3], in which for the detection of marine biological objects is the processing of acoustic signals reflected from biological objects.

The disadvantage of this method: the inability to distinguish between species, age, gender and state of aquatic organisms, as well as restrictions on distance.

Disclosure of invention

An object of the invention is the diagnosis of aquatic organisms (detection, location and movement, type, age, gender and condition).

The invention is carried out by using the dependence of the behavior of aquatic organisms (preferences of certain parameters of the living environment, speed of movement, characteristic movements depending on the species, age, gender and condition) on the temperature of the environment in which they are located. According to the invention, the temperature field is measured in the water area where hydrobionts are diagnosed, then in areas with characteristic temperature values an acoustic signal is emitted into the medium with a frequency, duration, filling frequency, power, radiation pattern, determined by the medium’s characteristics and measurement conditions, signal reception sound backscattering, measurement of the duration of a signal of volumetric backscattering of sound in a medium, which is used to judge the presence and accuracy of topolozhenii aquatic organisms in the target areas, their age, sex and condition and to empirically determine the dependence. To implement the method it is proposed to use an echo sounder. For example, as described in [4].

The method is characterized by the following sequences of operations. The temperature ranges are determined in which the behavior of aquatic organisms is determined empirically, for example, as described in [5] (preferences of certain environmental parameters, speed of movement, characteristic movements), depending on species, age, gender, and condition. In the water area where hydrobionts are diagnosed, the temperature field is measured and the presence, location and speed of movement of hydrobionts are determined using echolocation. According to previously established empirical dependences of the behavior of aquatic organisms (the preference of certain parameters of the habitat, speed of movement, characteristic movements), the type, age, gender, and condition of aquatic organisms are determined by temperature.

Thus, when measuring the temperature field in the water area under study, preliminary determination of the empirical dependences of the behavior of aquatic organisms (the preference of certain environmental parameters, speed of movement, and characteristic movements depending on species, age, gender, and condition) on temperature makes it possible to determine not only the presence and location of hydrobionts, but also their type, age, gender and condition.

The technical result is the determination of not only the presence and location, but also the species, age, gender and condition of aquatic organisms: fish and other aquaculture objects.
