Mallards Stock lakes with their poop

[Moveon]

Asian carp will live in any water but can not multiply if it is not a current driven lake because their eggs have to stay afloat to hatch

How does a current in the lake make fish eggs float? The density of the eggs is what makes them sink or float. It's all about buoyancy.

Not only that but most lakes have small wind-driven currents in them. And if what you say is true then lakes without rivers running through them to give them a current would be devoid of Asian Carp. If you remember right they imported these Asian carp and raised them in ponds down south. They escaped the farm ponds when there was a big flood and have been making their way up the Mississippi River System ever since. And Eggs that float up to the surface are exposed to more sunlight and UV Light at the surface than they would if they were to sink to the bottom, even in shallow waters.

Where do you come up with this stuff? Do you have any sources?
