Description
Technical Field
The invention relates to the technical field of marine environment protection, in particular to a reliable and practical mechanical acanthopoda starfish killing device and an operation method.
Background
In the past several years, the number of corals located in the coastal areas of the Pacific ocean and the Indian ocean is greatly reduced, the corals are not only caused by climate change, seawater pollution, catching damage and the like, but also have strong regeneration capacity, even if the corals are torn and thrown into the sea, each fragment can grow into a complete new starfish again, the individual starfish is large, the diameter of the adult radiation is 250-350 mm, the maximum diameter is over 700mm, the main food is the corals, the food intake is astonishing, the corals on the surfaces of the corals eat, white coral bones are left, and on average one starfish can eat about 2m a day2Coral of (1); the breeding capability of acanthopoda starfish is very strong, one adult acanthopoda female starfish is bred into hundreds of thousands of eggs each year, once fertilized, the adult acanthopoda female starfish can grow into a larva after being fertilized for 24 hours, the larva grows into five-wrist small acanthopoda starfish after being dispersed in the sea area for one month, and the adult acanthopoda starfish with the breeding capability becomes the adult acanthopoda starfish after two years; acanthopanax japonicus has a very strong ability to regenerate, and even if it is torn into pieces and thrown into the sea, each piece can grow into an intact individual again. The main natural enemy of acanthopanax pulicatus is the large fadrox, and in the past years, mankind catches the large fadrox in large quantities and sells the large fadrox for viewing and eating, which causes the continuous decrease of the number of the large fadrox, the acanthopanax pulicatus loses the natural enemy, and the coral destruction is more unscrupulous. Most feasibly, acanthopanax starfish suddenly appears in millions due to climate or environmental changes and the like, a large sheet of coral reef is eaten within a few days, the ecology of the coral reef is seriously damaged, and one fifth of ravage of the area of the Australian large fort reef is suffered. Therefore, the pest killing device can kill the pests quickly, effectively and conveniently, is an important way for protecting coral, and the physical killing plate is used for killing acanthopanax starfish in a manual way and is mainly carried by divers during diving.
The commonly used methods for preventing acanthopoda starfish are as follows: (1) divers carry toxic reagents (relative to starfishes, such as formaldehyde or acetic acid) to inject during diving, so that the divers are killed, but the method often has a limited amount of starfish cleaning due to the limited amount of reagents carried at one time; (2) the diver uses a tool (such as a diving knife or a biting stick) carried with the diver to destroy the internal tissues of acantho starfish so as to kill the acantho starfish in the diving process, but the method is very time-consuming, labor-consuming and inefficient, and some starfishes in deeper positions are difficult to eliminate; (3) the diver uses a metal bar or a net bag to capture and collect acanthopoda starfish in the diving process, then the acanthopoda starfish is taken back to the water surface and put under the sunshine to be dried and dehydrated to death, but in the capturing process and the carrying process, the diver is often stabbed and poisoned due to the complex diving environment and toxic thorn cells of the acanthopoda starfish.
However, the traditional acanthocoronary star killing method is an injection type, and a diver uses a syringe to inject special "venom" into the starfish body so as to kill the starfish. This method requires very specialized chemical reagent preparation and syringe use, and the syringe needs to be protected deliberately under the diving environment to prevent damage or accidental injury to others, which is not favorable for the wide-range popularization of this killing method. And the traditional common syringe needle is inconvenient to carry, store, place and use under water, and cannot well adapt to the diving environment and the application requirement of removing acanthopanax starfish.
