#春日生活打卡季#
A few days ago, I went to Runquan Lake for a walk, and saw that there were countless densely crowded small fish in the lake by the lake.
At a glance, there are a lot of fish in the lake, and it feels like even people with dense phobia can't stand it.
There seemed to be thousands of small fish, all one or two inches long, and occasionally a half-foot-long fish swimming around in the water.
In the secluded place by the lake, there are also people who are secretly fishing with fishing rods, and there are no park management staff, probably because of the holiday.
Ask the younger brother why the fish are so dense? The younger brother said:
"I guess the water quality is worse now, and there are too many oxygen-rich organisms in the water, so there are many small fish. ”
Speaking of this, the younger brother remembered again and said:
"If there are green plants like toad skins floating on the water, or if there are dense aquatic plants, small fish can still live, but at least the big fish in the water will definitely not live.
When I think about the scene I saw in the reed pond next to the lakeside road, it was as if there was a large layer of toad-like dirt floating on the water, and no one managed and salvaged it.
"The density of small fish makes it feel like there can be twenty or thirty fish in a place as big as the palm of my hand. I said to my little brother.
At least it shows that the water quality in Runquan Lake Park has not been completely destroyed, and if it is damaged, small fish can still survive, but big fish will die. ”
The younger brother smiled and his voice came out of his phone.
Who would have thought that after chatting with my little brother, I didn't go to Runquan Lake for a walk for two or three days, and when I went again yesterday, I saw two or three grass carp more than half a foot long from time to time, which were already turning their white bellies on the water, and the small fish next to them were still swimming around intensively.
"What a pity!" I said.
"Yes, these management staff don't say that they will salvage the impurities at the water's edge, maybe the water quality of the lake is better, and these fish, ducks and all kinds of water birds are also surviving. The husband also said dissatisfied.
Thinking of what I saw when I walked last year, the water quality here has always been good, the birds frolicking, the scene of coming and going from the south to the north, like this year, I really don't know how to treat it to get better?
