If we catch too much fish, will be less and less fish in the world. I know a lot of people love eating fish, but we should eat less. Or if we keep catching a lot of fishes, there will be no fishes in the future. And it will damage the natural sea world. So I would suggest fisherman need to limit the amount of fished they catch every day. Or we can only catch fish seasonally or only on Monday, Wednesday and Friday in a week.
