As the saying goes in the countryside, "A pig weighs 300 Jin, and a fish is too big to weigh". Why are there so few "big fish" now?

In the past, rural elders often said, "A pig is 300 Jin big, and a fish is too big to weigh." In other words, farmers used to raise pigs to 300 Jin, and even bigger pigs were rare. But there are no biggest fish in nature, only big fish. Some fish are too big to be weighed with a weighing rod. This sentence is a bit exaggerated, but some fish are really big. The reason why big fish are less and less common now is that there are more people fishing and there are fewer and fewer big fish.

1. More and more people are fishing.

As we all know, fishermen's basic working tools are fishing boats and fishing nets, but they don't need too many tools. Different from aquaculture such as fishing, as long as there are fishing boats and fishing nets, you can live in natural waters without investment. Apart from fishing gear, fishing is a profitable industry without capital. As a result, more people began to fish. In natural water, there are fewer and fewer fish, not to mention big fish. As a result, few people catch big fish now.

2. Limitations of fishing skills

Because the fish in natural water are usually small, the fishing gear used by fishermen is only suitable for catching fish of ordinary size, and it is impossible to catch big fish. Fishing for big fish requires expensive fishing equipment and technology. So under normal circumstances, fishermen can't catch big fish.

The number of big fish in natural water is decreasing gradually.

In the ocean, many countries and fishermen illegally engage in professional fishing for big fish, and the number of these big fish is gradually decreasing. Big fish fishing is actually beneficial to the development of marine fishing. Because big fish are mainly fierce predators, eating weak fish and catching big fish are beneficial to the growth of ordinary small fish and a good way to increase fishermen's output.

Due to excessive access to fishery resources in natural waters, big fish are almost never seen again.
