There are 70,000 fry in the fish pond. Why are there fewer fish?

There must be a reason for raising 70,000 fry less. The owner of the fish pond did not clean the fish pond before releasing the fry, so he planted a curse. Let's take a look at the general process of this incident.

There is such a graphic message that netizens are concerned. You can see dozens of big catfish more than one meter long in a boat. Looking at these giant catfish reminds people of a bumper harvest, but as the owner of these catfish and fish ponds, he is not happy, even crying, because he raises silver carp, carp and grass carp instead of catfish.

In the early spring, the owner of the fish pond bought more than 70 thousand fry and put them in the fish pond, thinking that there should be a bumper harvest in autumn, but the more he raised them, the more he felt wrong. If these 70,000 fry grow normally, the fish pond will be particularly lively after reaching a certain level. However, the owner of the fish pond did not see such a scene for a long time, but felt that there were fewer and fewer fish in the fish pond.

At first, he thought that someone must be stealing fish, and he did see some people fishing. He drove away the fishermen and strengthened supervision, but he still felt that the fish were decreasing. Nobody fishes. Why are there fewer fish? If this reduction continues, I'm afraid all the fish in this fish pond will be gone, so the owner of the fish pond gritted his teeth and drained the fish pond. After draining the fish pond, it was found that there were dozens of large catfish more than one meter long at the bottom of the fish pond. These catfish ate all the fry, and all the big fish and small fish were food in the catfish's mouth.

It turned out that due to the carelessness of the owner of the fish pond, the situation was not clear when he took over the contract for this fish pond. A nest of catfish at the bottom of the fish pond is neglected, which makes the fry lose a lot

Catfish is an omnivore with strong viability and fierceness. Any fish smaller than catfish may become catfish food.

To sum up, there are fewer and fewer fish in the fish pond because the owner of the fish pond ignores the original catfish in the fish pond.
