Electric Fishing Seine – Scientific Equipment for Electrofishing

General Description of the Electric Fishing Seine

In fact, professional biologists, researchers, and governmental organizations use our electric fishing seines. In addition, these specialized scientific tools are designed for conducting fisheries studies. For example, biologists mainly use them in rivers to count, sample, measure, weigh, and tag fish. As a result, the fish are released alive back into their natural habitat.

⚠️ However, authorities strictly regulate electrofishing and prohibit its use for commercial purposes. Therefore, it is only permitted within a scientific framework and in compliance with governmental standards.

Use and Principle of Electrofishing

For example, biologists use electrofishing in rivers to temporarily attract and immobilize fish. In fact, this method allows precise and efficient collection. Moreover, electrofishing ensures minimal stress and maximum capture accuracy for scientific studies.

Advantages of Using an Electric Seine

In fact, fish remain alive during the process. In addition, biologists retrieve them quickly. Moreover, the fish are re-oxygenated before release. Therefore, they are returned safely to their natural habitat. In fact, this method guarantees accurate sampling, minimal environmental impact, and high efficiency for biological surveys.

Technical Design of the Seine

In addition, the electric fishing seine is specially designed for river use. For example, a solid lower protective panel allows the addition of ballast. Moreover, the net stays in close contact with the riverbed. In fact, fine nylon or polypropylene mesh (Delta curtain type) ensures effective capture. In addition, the lower rope (ralingue) is weighted. Therefore, seams are reinforced with industrial stitching. As a result, fish cannot escape under the net, improving capture efficiency.

Technical Recommendations for Electrofishing

Because minimizing stress and injury to fish is essential, first, sampling should begin at low direct current voltage. Next, increase the voltage gradually until effective capture is achieved. Moreover, do not exceed 1.5–2 A depending on water conductivity. In addition, fish must not contact the anode (≈50 cm injury zone). Next, sweep the water with the electrode in a chevron pattern. Moreover, sample from downstream to upstream. Therefore, do not remain stationary in one area for too long. Finally, inspect nets frequently. In addition, stop operations if stress, injury, or abnormal recovery occurs.

Portable Wading Electrofishing

For example, portable wading electrofishing is recommended when the watercourse is narrow. Next, the depth is shallow. Moreover, the bottom is clearly visible. Finally, the substrate is heterogeneous, including gravel, rocks, or boulders. In fact, this method is especially effective for capturing species buried in the substrate, such as sand darters. ⚠️ In addition, formal training is strongly recommended due to the risk of electric shock.

Minimum Team Composition

In fact, an electrofishing team should include one operator of the device. Next, one or two net handlers are required. Finally, one person must oversee specimen collection, preservation, and habitat characterization. However, for watercourses wider than 7 meters, two teams are recommended.

Custom-Made Seines

Finally, we manufacture electric fishing seines to meet the specific needs of biologists, researchers, and scientific organizations. For example, choose the mesh type and size (1/8″ to 1/4″, sometimes 1/2″). Next, select the type of rope (ralingue) and ballast. In addition, configure the seine according to your scientific protocol. If, however, you cannot find the right seine, contact us. Therefore, we will manufacture it exactly according to your specifications.
