it comes down to more of the idea that you can only so much biomass in an area/pond and carp are prolific and adaptable and take overmeepster;1835759; said:

Carp and bass very much occupy the same habitat especially during the spawning season. Carp grubbing around and stirring up the substrate and water into a turbid mess also is not exactly good for Bass eggs. it smothers them and suffocates them. So yes there is a very good chance that in a small enclosed pond that Carp could very well wipe out Bass and sunfish populations.
I caught a small minnow about 5in long on a chartruse twistertail in a lake in SI. It looked JUST like the Rudd but it had Shiner colors. I wonder how many Shiners have died meaninglessly because of mistaken identity...
I always thought Round Gobies would make an AWESOME aquarium fish if they were legal. Check this out from Wikipedia, not all bad:
Invasive species
The species was accidentally introduced into the North American Great Lakes by way of ballast water transfer in cargo ships. First discovered in North America in the St. Clair River in 1990, the round goby is considered an invasive species with significant ecological and economic impact. An aggressive fish, the round goby outcompetes native species such as the sculpin and logperch for food (such as snails and mussels), shelter and nesting sites, substantially reducing their numbers. Round gobies are also voracious predators of eggs of native fish, many important to the angling industry. The goby's robust ability to survive in degraded environmental conditions has helped to increase its competitive advantage compared to native species. Many native predatory fish such as smallmouth bass, largemouth bass and walleye have begun to prey on round gobies. These game fish feed so heavily on the abundant gobies that a bait company, called Culprit, has created a soft plastic bait called the "Great Lakes Goby" to exploit this behavior. The incorporation of the round goby into native foodwebs, coupled with the goby's ability to consume large numbers of invasive mussels (zebra and quagga), may result in greater bioaccumulation of toxins such as PCBs higher in the food chain, since these mussels filter-feed and are known to accumulate persistent contaminants.
A smallmouth bass and a round goby put together for testing.
An unintended benefit of the round goby's introduction is that the Lake Erie Watersnake, an endangered species, has found it to be a tasty addition to its diet. A recent study found the introduced fish now accounts for up to 90% of the snake's diet. The new food supply means that the water snake is now staging a comeback. [1]
The round goby is also considered invasive in parts of Europe including the Gulf of Gdansk

This was clearly written before it was also found that the watersnakes have absorbed dangerous levels of heavy metal toxins from eating them.
(Round gobys feed on Zebra mussels which are toxin sponges) The affects of this bioaccumulation has actually reduced the fecundity of the snakes....
The snakehead is in the river closest to me, it is made fun of often by everyone there. Some Japanese guy bought them from a store to make soup for his sick wife. His wife got better and released them into the potomac river and they bred. I think that's what happened.
I was fish a damn in Clinton, KS two years ago. I was fishing for huge flathead catfish that are known to be at that damn. I usally use blue gill or whatever i can catch in a casting net to use for bait. So a few throws in i net a 8 pound big head carp. I remembered it from the bait store are a problem fish so i just threw it on side. I threw again and got a 5 pound and a 3 pound. I threw them on the side to. So i notice out of the corner of my eye this asian man running to his car and put his fishing gear up. I didnt think nothing of it. I look at him again and he's walking very awkardly toward me. I didnt think nothing of it. I look again, and he gone. I turn around and he grabbed the fish and was hauling tail to his car. He threw them in his station wagon and pelled out.
This guy stole them from me lol! He missed out thou cause my dad caught a 70 pounder and i caught a 35.

I don't know if it was mentiond before but in early December a few silver carp were caught in a commerical fishing net near La Crosse WI. It was the fist confirmed id of this species north of Clinton Iowa on the Mississippi River and the first id in any wisconsin waters.
how do we all tjink of invasive gobies? i love them and think they are cool but i kill them when i catch them up in the great lakes for obvious reasons
