The invention presents a multi-layered, intelligent barrier system that does not require physical barriers. The developed system consists of a bubble curtain, an acoustic (sound-based) barrier, and 10 three different technologies integrated together, including optical (light-based) barriers. It is based on the use of these components, which are species-specific sensory inputs of fish. targeting perception mechanisms and natural avoidance behaviors designed so that the boundaries of the defined production area are behaviorally By enabling its detection, the fish can effectively leave this area. 15 It prevents this.

It has been improved so that fish can be kept without the need for physical cage or net systems. 20 multi-layered, AI-powered systems that ensure the water is contained within a specific volume. and provides a barrier system with adaptive properties. The invention is a product. They are of a nature that allows them to work in an integrated manner and functionally complement each other. It consists of multiple subsystems. The invention is physically interconnected or independent of each other. It consists of four main subsystems designed to function in this way. The subsystems in question are: bubble barrier subsystem, acoustic (sound) barrier subsystem 25 the control system consists of an optical (light) barrier subsystem and a central artificial intelligence unit. It is a unit (4). These four subsystems are the sensor network placed underwater and above water. It operates within an integrated structure with the localized energy sources. The physical structure of the bubble barrier subsystem, one of the subsystems in the invention, is water placed at the bottom of the column and defining the boundaries of the area to be enclosed laid in this way, made of corrosion-resistant material (preferably stainless steel or made of high-density polyethylene (HDPE), with micro-perforations at regular intervals. It is a bubble barrier pipeline (7). Fittings, bubble barrier 5 The weights and anchors that secure the pipeline (7) to the seabed. Air supply For this, the system can be used as a buoy on land or in the preferred application of the invention. low noise level located on the floating platform (3) used In its oil-free structure, the preferred application of the invention is as a compressor. It is supplied by the air supply unit (5). The air supply unit (5) is 10 The bubble barrier is connected to the pipeline (7) by a flexible hose. The bubble barrier bottom In the system, compressed air from the air supply unit (5) passes through the bubble barrier tube a dense mass that emerges from the micro-holes on the line (7) and rises to the surface of the water This microbubble wall (8) is formed by fish. From this point of view, it constitutes both a visual obstacle and causes turbulence in the water flow. 15 by creating bubbles, it physically hinders the passage of fish. The barrier subsystem contributes to oxygen transfer to the water, improving the aquaculture environment. It helps to improve water quality. In the acoustic (sound) barrier subsystem, another subsystem in the invention, water One or more 20 in a leakproof, high-pressure resistant, stainless steel housing Acoustic barrier module with extra underwater speaker (hydroacoustic transducer) (10) It is located. The acoustic barrier subsystem is situated just inside the bubble barrier, They are positioned at specific intervals and at different depths (e.g., 2m, 5m, 10m). The amplifier and voice synthesizer, located in the acoustic barrier subsystem, are central. By processing the digital signals coming from the control unit (4), which is an artificial intelligence unit, it produces high 25 It is an electronic circuit that converts analog sound (acoustic signals) into a powerful analog sound. Acoustic barrier subsystem to be suitable for the sensory sensitivity of the target fish population (9) in a specifically defined, disturbing frequency range (preferably 200-2000) It produces sound waves (Hz). These sounds trigger the fish's avoidance reflex. It triggers the acoustic barrier subsystem, controlled by a central artificial intelligence unit, Control 30. Dynamically adjusts the frequency, amplitude, and sound pattern (intermittent, under the control of the unit (4)). It can change the (rising / falling) stimulus. In this way, the fish are not constantly exposed to the same stimulus. 6 The habituation effect that may occur as a result of exposure is prevented. and the barrier effectiveness is made sustainable. Digital signal processing; acoustic signal processing chain, from the control unit (4) the transformation that digital audio data undergoes before being transmitted to underwater speakers and This chain includes the amplification stages. This chain, in order, digital audio 5 synthesis, digital-to-analog conversion (DAC), and analog power amplification It consists of steps. In digital voice synthesis; the control unit (4) is directed to the target fish population (9) the frequency, amplitude, and pattern information of the acoustic stimulus to be applied as numerical data It produces [wave table] using wave table synthesis or sampling methods. This is being carried out. In wave table synthesis, pre-recorded or mathematically modeled sound waveforms in a digital memory table stored and control unit (4), selects the appropriate waveform from this table sound It generates a signal. Alternatively, in the sampling method, the target fish species Sound samples known to trigger avoidance behavior can be used directly. 15 In Digital-Analog Conversion (DAC); the digital sound produced by the control unit (4) The data is converted into an analog signal via a digital-to-analog converter (DAC). The DAC converts digital values ​​encoded in binary system into corresponding continuous amplitude voltages. or is an electronic circuit that converts incoming current into a higher level. The conversion process involves each incoming current. the digital data packet is held for a sampling period and then analog 20 by converting the stepped signal into a smooth waveform through filtering This is being implemented. The system preferably uses a sigma-delta or R-2R ladder. DACs with this architecture can be used. In analog power amplification, the low-level analog signal at the DAC output, The amplifier has a power level of 25 that can drive underwater speakers. is amplified. The amplifier increases the voltage and current gain of the signal coming from the DAC. increasing the electrical power to create a sufficient magnetic field on the speaker coil This provides a Class-D high-efficiency system suitable for underwater environments. Various amplifier topologies can be chosen. 7 In acoustic broadcasting; amplified analog signal, acoustic barrier module (10) This information is transmitted to the hydroacoustic transducers (underwater speakers) within the device. The transducer converts the electrical signal into mechanical pressure waves propagating in the water medium. It converts (into sound waves). Thus, the control unit (4) determines Frequency (preferably 200-2000 Hz), amplitude, and pattern (intermittent, rising / falling) 5 The acoustic stimulus with these characteristics is transmitted to the target fish population (9). In the optical (light) barrier subsystem, another of the subsystems in the invention, water leakproof, high pressure resistant, UV resistant polycarbonate tubes optics that provide high-brightness blue and white LED arrays embedded inside. The barrier module (11) is located. The optical barrier subsystem is the same as the acoustic barrier. along the line, but at different depths and especially in the area near the surface. It is becoming more concentrated. The driver circuit controls the light intensity, blinking speed, and light of the LEDs. controlling the pattern (sudden flashes, flickering / shifting light effects, constant lighting) It is an electronic circuit. The optical barrier subsystem is especially useful in low visibility conditions (night, Twilight (high turbidity water) creates a visual barrier. 15 Preferably blue light (440-460 nm) whose effectiveness has been proven by scientific studies. It is used. The flashing pattern of light elicits avoidance and startle responses in fish. It is constantly being modified to create it. Depth positioning of the optical barrier module (11), acoustic barrier module (10) on the same vertical plane, but in different layers of the water column 20 is performed. The optical barrier module (11) is used to measure the target fish population (9) by taking advantage of the type and depth-dependent behavioral responses it exhibits to light preferably concentrated in the area 1-5 meters below the surface It is located. Scientific studies have shown that Atlantic salmon (Salmo salar) are sensitive to underwater artificial light sources for 25 minutes. This shows that the response can vary depending on the depth. For example, 8 meters salmon approaching (or being drawn to) a light source positioned at depth It showed a reaction, however, the same light source was lowered to a depth of 12 meters. In this situation, it was observed that the fish moved away from the light source. This finding suggests optical... The effectiveness of the barrier depends not only on the light intensity and pattern, but also on the source's 30 It also reveals that it depends on its vertical position in the water column. 8 Therefore, in a preferred application of the invention, the optical barrier module (11) can be used to protect water. They are placed along a line 1-5 meters below the surface. This depth range, to keep the target fish population (9) within the specified water volume of the system while creating the necessary visual barrier, it also provides protection in low visibility conditions (night, (twilight, murky water) an effective avoidance response to light in the region near the water surface 5 It enables the creation of. The depth position of the optical barrier module (11) is determined by the sensor via the control unit (4). data (turbidity, light level, temperature) and instantaneous data of the target fish population (9) depending on its behavior (via underwater camera and image processing module (12)) It can be dynamically adjusted. This adaptive depth control allows the optical barrier to be 10 Its effectiveness is made sustainable under different environmental conditions.
