Does silver carp have fish roe?

I have seen silver carp eggs in natural waters, and they are a little green! The breeding conditions should be nothing more than temperature, water flow, environment, and appropriate weight! In addition, since silver carp and bighead carp eggs are not sticky, in general inland rivers and lakes, the eggs will sink to the bottom of the water because the flow rate cannot reach a certain level, causing the eggs to rot due to lack of oxygen. Therefore, the parents usually mate and lay eggs in the middle and upper reaches of the Yangtze River. Due to the water flow and drop, the eggs drift downstream in the middle layer of the water, and the rich oxygen...

Please analyze the ecological niche of the four major carps, silver carp, bighead carp, and black carp, which are mixed cultured in ponds. Thank you.

Due to their different living habits, the four major carps, silver carp, grass carp, bighead carp and black carp, are distributed in different water layers of the pond. This is a stratification phenomenon of aquatic animals and therefore reflects the vertical structure of the community.

Therefore, the answer is: b.
