Why do we have no fish to catch?

In Shenzhen, every time I go fishing with three or five friends, except for breeding ponds and fishing grounds, I find that I can't go wild fishing, or I can't find a fishing place. Many times, even if we go fishing on offshore rafts, we will find that the fish caught are getting smaller and smaller, or there is no fish to catch!

Fishing friends can't help but sigh! Why don't we have any fish to catch? Many times we go to the reservoir fishing ground. Besides tilapia, small fish are still small fish. Every time I come back, it is mostly the air force or turtle hunting, which has become the mantra of fishing friends! While wondering, we also know the problem!

Fishermen have almost no other hobbies except fishing. They don't eat, drink or gamble. They are single-minded. Fishing is also a sport beneficial to physical and mental health, and sea fishing in fishing is known as one of the four big noble sports. Fishermen seldom eat fish, but they usually let the big fish go. Many times when they catch fish, they will be released. They only care about the fishing process and the fun when the fish are hooked, and will not have any impact on fish resources! Then why do we still have no fish to catch? Tracing back to the source, there are several reasons: first, predatory acquisition of fish resources, second, environmental pollution, and third, invasion of alien species.

As the world's largest consumer of aquatic products, China's offshore fish resources are almost exhausted, and most of the fish caught by fishing boats are inedible small fish and miscellaneous fish-or "feed fish".

This is 20 16, 12, 17, Shidao, Shandong, a juvenile brown squid. Fall into a net. Brown dragon? Also known as "fake grouper", it is a common edible fish in the offshore, with tender meat and delicious taste. Brown calamus weighing more than 2? Can be sold to 30 yuan/Jin, and this brown calamus? When used as feed, the maximum price can only be 1 yuan 1 kg.

This kind of white strip was obtained by a fishing friend. It's not genetic mutation or environmental pollution. Fishing friends know at a glance that the fish has been deformed by electricity! Fish that have survived are caught again, and fishermen usually release them. Electric fish is another kind of destruction to fish resources. Fishermen all know that few fish can be caught in the electrified waters, and the electrified fish cannot lay eggs and breed.

There are many ways to obtain fish resources by predation, but the ultimate harm is the same. Will our descendants have no fish to catch in the future?

I remember that every time we go fishing, we will ask each other how the water quality there is and whether the fish can be eaten. Whether fish can be eaten is a problem. Factory sewage and human activities lead to eutrophication of water quality. We have been to Xiaogui many times, where red tides occur in summer. "The color of water is red. How can there be fish?" A fisherman shook his head and told us not to hunt turtles.

The greater harm of red tide is that it leads to the large-scale death of fish, and water pollution leads to no fish for us to eat! In fact, when we were young, there were a lot of fish and shrimp and the water was very clear. After all, environmental pollution was not caused in a day. How to break the infinite cycle of "pollution first and then treatment" in the future is also a long way to go.

Invasion of alien species, a fishing friend said that as long as tilapia is in the place, other fish can't eat anything. Isn't this a joke? Gradually, there are fewer and fewer local crucian carp, and we find that they are all African crucian carp. Luo Fei, tortoise, scavenger, eel, crocodile turtle and snail are animal terms that we rarely heard and saw when we were children, but now we have become accustomed to them in our lives, and fishermen talk about them the most. The invasion of alien species directly leads to the rapid extinction of local species and directly destroys the original ecological balance of the local area for thousands of years. This is an ecological disaster.

Predatory acquisition of fish resources, environmental pollution, invasion of alien species. These are the three major ecological problems that we have been unable to avoid, but as fishermen, we have more personal feelings. After all, we don't want to have no fish to fish and eat in the future. These three dilemmas will always accompany us. After all, on the one hand, our ecological awareness will become stronger and stronger. As fishermen, we will take responsibility, influence our families to care for the environment, break through all difficulties and tell the world that destroying the ecology is not the responsibility of one or two of us, but the interests of all of us!
