Calm down guys this is a scientific discussion, not a religious discussion. i'm not dictating anything on what you should or should not do. i'm not telling you that youll rot in the firey depths of the sepulture if you dont give up your home reef, lol. its just to stimulate thinking, that is all. so please share your thoughts even if you think theyre only worth 2cents. at least, this is far more fun than talking about "How many watts of light should I put on a 55gallon tank?"
Can you name an invasive species that has appeared in the Great Lakes system due to the dumping or flushing of marine water from home aquariums? And if so what effect has it had on the system?
Yes i can.
Pterois volitans (lion fish) is non-native to the atlantic ocean. there are reports of sightings as far north as cape cod.
Condylactis gigantea (condy anenome) is also non-native to the atlantic. the clown fish is an extinct species in this biotope.
The EU has declared the mediterranean an ecological disaster because caulerpa has overgrown everything.
Closer to home...the dreissena polymorpha (zebra mussles) are filtering algae and sediment in the water of the great lakes effectively destroying the natural habitat of stizostedion vitreum (walleye). stizostedion vitreum is very light sensitive. the clean and clear water that dreissena polymorpha creates causes stizostedion vitreum to seek deeper and more remote waters seperating it from the schools of bait fish.
Neogobius melanostomus (round goby) has destroyed the schools of bait fish that once dominated the near shore waters of the great lakes.
Channa micropeltes (chinese snakehead) has been ravaging the waters of the inland lakes and ponds of the eastern us. this species is of particular importantance due to its ability to survive outside of water for up to 48hours.
In aquarium waste water there could be millions of species of bacteria and microscopic organisms. really...the average aquarist is playing a guessing game on exactly what the contents of the system really are. simple fact is we just dont know. yes, the instant pH drops or rises in water the organism goes bye bye. buuut what if they dont? what if out of the millions...something survives...
Weather these species ceom from the home aquarium or the ballasts of oceanbound vessels. theyre here and what are we going to do about it and what are we going to do to prevent it in the future?
Emprr_angl is concerned with marine aquarium enthusiast dumping a small amount of water into drains weekly when in reality the amounts of water brought in by ship ballasts is who knows how much greater and more dangerous to the Great Lakes.
right on. i've seen this with my own eyes. being a fisherman of the great lakes. i've never seen a coast gaurd patrolling the waters. its pretty much a free for all. i've seen 55gallon barrels of unknown contents being dumped overboard in saginaw bay, questioning my father why we dont do anything. dad says we dont want to get involved...and what are we going to do anyway?
The amount of damage we do is miniscule to the amount of damage farms and lawn companies do with pesticides, and fertilizers.
again right on.
does your lawn really need to be green green? hm, those signs that tell you not to walk on the grass after its been sprayed are scary. i know my animals (cats & dogs) have gotten sick from playing in the grass after a spray... beyond that, what purpose does it serve except to say to your neighbor, MMMY laaawn is greener than yours!
dont even get me started on golf courses...
it were up to the "environmentalists" we...
no need to get nasty. this is just conversation.
