I definately agree its territorial behavior while they are nesting; at a pond i Sequiota park here in sfld mo ive watched the same behavior by green sunfish attacking much larger carp who approached while they were nesting in the spring....but i had a conservation agent tell me once while i was fishing on the James that when fisherman catch the bass guarding their eggs on the nests the Carp/suckers etc will come in and eat the eggs, but that the eggs have a much higher success ratio of living if the bass defending the nests are not caught and there to defend them.

The bass killed a koi carp was due to territorial behavior...it has nothing do with the nesting at all. I've had territorial sunfish/bass in the past and they don't have even a nest they were being territorial that's all. I witnessed a bass tried protect the nest from a group of carps and I've seen a carp bulldozing into the sunfish colonies even the sunfish attack on him has no effect on the carp as it is eating the eggs.
Wow thats insane.....no wonder everyones trying to get rid of these asian carp that are spreading so fast here in the midwest, although Ive never seen that, I have no doubt that it happens.
Asian carp and common carp are not same fish. Common carp are more like tank while asian carps tends be pelagic. Also common carps have different effects on the ecosystems such as uprooting the bottoms while asian carps simply eating all plankton and out numbered other natives.
MN_Rebel is exactly right. We've been hearing quite a bit about them in the upper midwest as the asian carp make their way up the Mississippi. Big concern to the large gamefish population if they continue to spread.
Not completely true, Black head or "snail carp" is not a filter feeder and eats snails, clams, invertabrates, and crustaceans, heres the wikipedia article on them, " andThe nature of the black carp's diet has led to its use in the United States in the control of snails in aquaculture. Snails are obligate alternate hosts of trematode pests that can cause substantial losses to aquaculture crops. Some state aquaculture laws require the carp to be bred as triploids, to render them sterile, and thus minimize the potential for the fish to escape and create self-sustaining populations. However, the use of triploids does require the maintenance and use of fertile diploid brood stock at least at some location, for production of the triploids.
Black carp are considered to be a serious threat to mollusks native to the United States, many of which are critically endangered. In 2007, the black carp was listed as an "injurious species" under the Lacey Act.[4] "
Grass and silver carp can and do eat larval fish and eggs while eating vegetation or filter feeding, Heres and excellent article with lots of research;

Except the asian carps we talking about are usually silver and bighead. We don't usually lumping grass carp to the asian carps.
Another problem is that black carps are very rare in the wild and they don't made to the top news. We don't even if they are reproducing in the wild. So we usually don't really view black carps as Asian carp.
