Overfishing. The vastness of the ocean provides the widest space for life to grow. Humans have been fishing and hunting since ancient times.
Today it has been replaced by large-scale industrial fishery production. Humanity is taking more and more from the ocean as it marches into the ocean. When human demands exceed the limits of what the ocean can carry, the ocean's fishery resources begin to shrink and eventually become extinct.
In recent years, with the rapid growth of the world's population, the development of world fishery production has been rapid, and the phenomenon of overfishing has occurred in many fishing areas.
China's Zhoushan Fishing Ground was once one of the world's famous fishing grounds until the 70s of this century. It is where the cold currents of the north meet the warm currents of the south, and there is an abundance of fish. However, due to overfishing by local fishermen, the yellow croaker that used to be abundant in the area has almost been extinct.
Whaling was once the worst human record of destruction of marine resources. Because whale oil can be eaten, whale meat is as delicious as veal, whale skin can be tanned, and whale liver can be made into cod liver oil, so before the rise of chemical industry with petroleum as raw material, whale has become an important industrial raw material. The boom in whaling at the beginning of this century brought about the destruction of the world's cetacean resources.
Early whaling ships were powered by sails, and hunters stabbed whales in the back with barbed spears. Then, let the whale struggle until it is exhausted. The whales are then tied to their tail fins with thick ropes and dragged aboard the boat for slaughter.
The invention of the whaling cannon allowed the whaling industry to flourish. The whaling fork was installed in front of the muzzle, and the shooter aimed at the whale as it breathed at the surface of the sea, and when the whaling fork pierced into the whale's body, the desperate cries of the cetaceans were heard. It takes a long half hour for these whales to die in agony.
Here, humanity becomes an inhuman executioner. At the initiative of people of good will, the international community has finally adopted an international convention for the protection of cetacean resources. However, some peoples who have a habit of eating whale meat are still engaged in illegal whaling**.

It is important for the growth and reproduction of sea bass, preventing its extinction and conserving natural resources.
A regular ban on fishing is to protect the reproduction and growth of fish. Spring is the breeding period, spawning period for fish. From February to June, fish are relatively clustered during this period.
A ban on fishing will be enforced and parents and juveniles of most fish will be protected. The imposition of a fishing ban will facilitate the breeding and protection of fish during the spawning period.
A closed period is a period during which the fishing of animals in the sea is prohibited or restricted. Its purpose is to protect the normal growth or reproduction of aquatic organisms and to ensure the continuous recovery and development of fish stocks.
Stipulating the fishing ban period is a fish resource protection system commonly practiced in all countries in the world, and China's fishery laws and regulations also clearly stipulate this system. In accordance with the provisions of China's "Fishery Law" and other laws and regulations, the fishing ban period shall be stipulated by the people's fishery administrative departments at or above the county level.

First of all, the most direct and dangerous thing about electrofishing is safety. Not only the safety of the fishermen themselves, but also passers-by passing through these waters, can become victims, and there was a case in the news that a farmer who caused the death of a passer-by due to electric fishing was sentenced to 10 months in prison for endangering public safety. Electrofishing is fatal to people and fish, whether it is the use of private wires or batteries.
Secondly, according to relevant experts, the taste of the fish caught by electrofishing has changed, which will have an impact on both people and fish, so there is a saying in the folk that "no household" fishing, because even if the fish that escaped through the net at that time often could not escape death, and the fish that had been electrocuted had their gonadal development damaged and basically lost their reproductive ability, resulting in "cutting off their offspring and grandchildren".
Again, electrofishing endangers the entire body of water. Now the electric fishing equipment is constantly upgrading, the output voltage can even reach thousands of volts, in addition to seriously endangering the reproduction of fish, but also to grow in the water of small fish shrimp, shell snails, microorganisms and other ecological environment or microbial environment to cause devastating damage, seriously affect the balance of fishery resources, seriously threaten the balance of human living environment.
