Previous Technique Fish sampling studies in freshwater ecosystems are important for fish biology and ecosystem health. It is of critical importance in terms of evaluation. Among traditional methods, different perspectives... 10 These include nets with openings, cast nets, gill nets, traps, and fish traps. These methods are often able to target specific species or individuals of a particular size. However, it is insufficient in representing the holistic structure of fish communities. In particular Benthic species, individuals that hide under stones or in mud, or through mesh openings Small species that can easily escape cannot be sampled with current methods. Furthermore, 15 in net fishing by getting caught in the gills of fish or trapped in the gaps of the net Injuries, deaths, or stressful experiences are frequently observed, which is an ecological issue. This negatively affects sampling accuracy in studies. Therefore, traditional networks Based on these methods, neither can fully reflect the species diversity nor can the fish be accurately represented. It is unable to maintain its physiological integrity. 20 Scientific electroshock methods have historically generally relied on generator-based systems. These systems were mostly powered by diesel generators that supplied 220 / 240 V mains electricity. It operates under high voltage, poses vital risks to the user, and is used in an aquatic environment. It lacks suitable safety measures for use. Furthermore, the generator... Precise control of parameters such as frequency, voltage, and duty cycle is possible in these systems. 25 This does not happen, which limits the effectiveness of electroshock and causes irreversible damage to fish. This can lead to damage. The bulky and fuel-powered nature of generators makes them difficult to transport. and imposes significant restrictions in terms of access, as well as air and noise pollution. This makes field work more difficult. Therefore, existing electroshock devices It falls short in terms of both safety and ecological sustainability, scientifically 30 It fails to ensure standardization and comparability in sampling. The current situation... These limitations in techniques prevent both the complete sampling of fish diversity and... This can be summarized as the high risk of harm to fish and users. 2 Application number RU2626154C1 concerns the harvesting of Pacific mackerel (saury) without the use of nets. It describes a method for hunting fish. The method involves attracting fish with bait, The accumulation and concentration of fish in a specific area with the help of an electric current field. It is based on the principle of taking it through a pump. During the feeding phase, the ship The water surface is illuminated by light sources fixed to its sides, in blue-green and white colors. The lamps are positioned at a 45° angle to provide illumination not exceeding 700 lux. During the concentration phase, the light sources are blue, offering the possibility of individual switching. Equipped with green and red lights, it provides a maximum illumination of 200 lux. To guide the fish and provide the electroanesthesia effect, three electrodes – two A device consisting of a cathode and an anode is used, these electrodes are placed on the 10 inch tube of the fish pump. They are fixed in place and positioned so that the distance between them does not exceed 3 meters. The potential difference between the electrodes is 1–2 V for galvanotaxis and 2.5–3 V for galvanonarcosis. It is kept within the V range. This method is an innovative way to increase hunting efficiency. It offers an approach. Application number US3693276A concerns a 15-year-old project for electric fishing in the marine environment. This describes the device. The device detects fish at a galvanotactic threshold equal to or exceeding that threshold. It includes an array of electrodes exposed to an electric field. The electrode structure consists of an anode and It consists of two cathodes arranged in an equilateral triangle shape, and the power source is the fish. It provides pulsed direct current voltage to control its movement. The studies revealed that 20 fish samples were collected in freshwater and marine environments. The currently used methods appear to have significant limitations. The traditional network, Spreading and trap-based methods only have certain size and behavioral characteristics. It can catch species such as benthic species, those hiding under rocks, or small-sized individuals. A significant portion of communities cannot be exemplified by these methods. Light attraction and... In existing solutions based on the principle of creating an electroshock field, the lighting used is 25 The limited spectral efficiency of the sources means that fish can only be observed for a short period and in part. This leads to better orientation; furthermore, it provides better electrode arrangement and voltage control. Low sensitivity can cause harm to fish or irreversible damage instead of electroanesthesia. This causes exposure to electroshock. It is based on a high-voltage generator. These systems pose serious risks in terms of user security and portability. It remains limited and does not allow for precise adjustment of the parameters to suit the aquatic environment.
