No chance for cormorants – protect your fish stocks now
Cormorants – The skillful fish hunters of the waters
Cormorants live primarily in lakes, rivers, coasts, and wetlands. They reach a body length of about 70 to 100 cm and have a wingspan of approximately 120 to 160 cm. They feed mainly on fish, preferring specimens with a body length of ten to twenty centimeters. Cormorants breed in colonies, either on coastal cliffs or inland on trees. Often, the strong, lime-rich droppings of the birds damage the leaves, making the trees appear bare in cormorant colonies. Despite these effects on vegetation, cormorant populations remain stable.
When cormorants threaten fish stocks...
Although cormorants are considered beneficial in many regions because they help maintain fish population balance, they are often seen as competition by fisheries. Cormorants specifically target ponds with easily accessible food. In carp and trout farming, they not only cause significant fish losses but can also injure the fish. Without professional cormorant deterrence, substantial economic damage can occur. Farmers and pond managers must act early to scare off cormorants and secure their stocks long-term. In some countries, special protection measures exist to balance species conservation with fisheries interests.
Effectively and sustainably scaring off cormorants
To scare off cormorants, a combination of proven methods is recommended:
-
Purivox noise deterrent devices: Generate targeted noise impulses at irregular intervals, reliably and permanently keeping cormorants away from ponds.
-
Lasers: Especially effective during early morning or evening hours, gently and humanely repelling cormorants.
-
Nets: Provide physical protection and prevent the birds from entering the ponds.
Combining these measures ensures that cormorants do not get used to individual methods. Professional cormorant deterrence protects fish stocks long-term and reduces damage permanently.

The Purivox Carousel Triplex V with analogue time switch is a rotating gas cannon for bird control for large areas. The tripod allows the unit to stand securely on any surface. The Purivox Carousel Triplex V is used for fruit growing, viticulture, vegetable growing, arable farming, fish farming and on waste disposal sites. Due to its special design, the complete top structure is pivoted. When the device is triggered at random intervalls, the top structure starts to rotate due to the recoil. The two following shots cover an area of 360° around the unit. Various adjustment possibilities offer an individual adaptaion to the respective bird control. With the help of the electronic unit, the number of shots, irregular pause times as well as the volume can be adjusted in two steps. Furthermore, the analogue 24h time switch allows the adjustement of active and rest times. Operating principle The reliable 3-times shot enables the best possible bird control. The first shot will startle the birds and cause them to fly up. The second shot is fired shortly after the birds fly up and prevents them from settling down again. With the following third shot, the animals are finally chased away. How to set the electronic unit:
The Purivox RC Triplex V is a compact gas cannon for mobile bird and wild animal control. The Purivox RC Triplex V is used for fruit growing, viticulture, vegetable growing, arable farming, fish farming and on waste disposal sites. Various setting options offer an individual adaptation to the respective bird control or situation. With the help of the electronic unit, the number of shots, irregular pause times as well as the volume can be adjusted in two steps. In addition, the volume can be additionally regulated by adjusting the length of the firing tube. The Purivox RC Triplex V is equipped with a radio receiver (433MHz) which allows manual activation and shooting only when there are really birds nearby. The antenna is screwed onto a plate on the side of the electronic unit. Operating principle With the Purivox RC Triplex V, shots can be fired manually when birds are nearby. To do this, the device is directly activated by a simple push of a button using the radio hand transmitter (triggering within a few seconds). The reliable 3-times shot enables the best possible bird control. The first shot will startle the birds and cause them to fly up. The second shot is fired shortly after the birds fly up and prevents them from settling down again. With the following third shot, the animals are finally chased away.
The Birdzout Auto Laser Ultimate is a powerful and automatic solution for effective bird control over large areas. The moving green laser beam triggers a natural escape instinct in many bird species, as it is perceived by the animals as an approaching movement. As a result, birds reliably avoid the protected area. Thanks to 360° rotation with pan & tilt function, the laser automatically covers large areas. Depending on lighting conditions, a range of up to 400 meters in sunlight can be achieved, protecting areas of up to 30 hectares. The system is conveniently controlled via an app (Android & iPhone). Various settings such as speed, brightness, pulse mode, and movement patterns can be individually adjusted. In addition, zones and boundaries can be defined so that the laser operates only in desired areas. Integrated timer functions allow automatic scheduling of operating times. The high-quality Class 3B laser was developed for professional use and is a cost-efficient bird deterrent solution for agriculture, industry, and large open spaces. Optional tripod, solar kit, and batteries are available for flexible installation. Operating Principle The laser is installed at an elevated position so that the beam can cover the area to be protected as evenly as possible. After programming via the app, the laser beam automatically moves across the defined areas. Through pan and tilt movement, the laser is guided over the ground and possible bird resting areas. The moving beam creates the impression of an approaching threat for the birds. As a result, they react with escape behavior and increasingly avoid the area. Various movement modes, speeds, and the optional pulsing beam prevent birds from becoming accustomed to the system. With regular use, the protected area is perceived as unsafe in the long term and avoided by birds.
