Description

Starfish killing device

Technical Field

The utility model belongs to the technical field of marine environment protection, and particularly relates to a starfish killing device.

Background

In recent years, the number of corals in the coasts of Pacific and Indian ocean is greatly reduced, and besides factors such as climate change, seawater pollution and fishing damage, the damage of the long-spiny starfish is also an important reason, and each fragment can be regrown into a complete new starfish even if the long-spiny starfish is shredded and thrown into the sea due to the strong regeneration capability of the long-spiny starfish, so that the method is an important mode for protecting the corals, and the method can kill the harmful organisms rapidly, effectively and conveniently.

The common modes for preventing and controlling the long thorn starfish are as follows: (1) Divers carry "toxic" reagents (relative to starfish, such as formaldehyde or acetic acid, etc.) during diving to kill them by injecting them, but this approach tends to be limited in the number of starfish to be cleared due to the limited number of reagents carried at one time; (2) The diver uses a portable tool (such as a diving knife or a biting rod) to destroy the internal tissues of the long-spine starfish to kill the long-spine starfish in the diving process, but the method is very time-consuming, labor-consuming and low in efficiency, and the starfish with deeper positions are difficult to eliminate; (3) The diver uses metal bar or string bag to catch and collect long thorn starfish in the diving process, then takes the long thorn starfish back to the water surface and places the long thorn starfish under the sun for sun drying and dehydration to death, but in the capturing process and the carrying process, due to complex diving environment and toxic cells of the toxic thorn starfish, the diver is often stabbed and poisoned.

The traditional method for killing the long-spiny starfish is injection type, and a diver uses an injector to inject special 'venom' into the starfish body so as to kill the starfish. This approach requires very specialized chemical preparation and syringe usage, and the syringe needs to be deliberately protected under the diving environment to prevent damage or accidental injury to others, which is not conducive to the wide spread of the killing approach.
