Speaking of greedy fish.
I was gone for a weekend, when I got back, there were 4 less fish in my
natives tank. All of my sunfish were gone. At first I blamed Mike as two of
my tanks looked as though he had dumped a whole can of flakes in. He swore
that he had not killed any of my beloved fish. The next day or so I kept
watch over them and noticed my smallmouth bass was being particularly
aggressive. I thought that it was unlikely that this 3.5" bass could swallow
the 1" sunfish, when my glassfish of the same size are still there. To test
this I got some big fat rosy minnows, approximately the same volume as one
of my former sunfish.
As I dumped them in, that SMB gulped one down! It was a gruesome death for
the rosies, I never figured that a fish's mouth could stretch so much! I'm
not mad at Mike anymore, but I still don't see how a little bass could eat
something the shape of a comparatively large sunfish.

U.S., Canada too late to halt invasive species
10/31/02

Fisherman on Lake Erie and around the Great Lakes have known for a decade
that invasive species are a serious threat, but government officials in the
U.S. and Canada finally got around to stating the obvious in concurrent
reports issued last week.
The agencies said not enough is being done to stop invasive species from
entering the Great Lakes. The lack of action over the past 17 years is
costing billions of dollars annually as sport and commercial fisheries
decline.

The Great Lakes Fishery Commission strongly agreed with the reports issued
by the Auditor General of Canada and the U.S. General Accounting Office.
Invasive species present a very real and significant economic and
environmental threat to the Great Lakes, said commission chair Bill Beamish.

To point out at this late date that not enough is being done to stop
invasive species is a slap in the face. Lake Erie angling already has
suffered greatly since the arrival of zebra mussels, quagga mussels, round
gobies, spiny water fleas, white perch, sea lampreys, fish hook fleas, ruffe
and a host of other visitors.
Fishermen have complained. No one ever seemed to listen.
Sportsmen also know that the barn door has been open for far too long.
Without the rigid controls needed to slam the door on the exotic organisms,
they have arrived and flourished.
No matter how many reports are issued, the invasive species are here to
stay. Removal is impossible. Like carp and sea lamprey, they will flourish
and impact native species of fish.
The floor of Lake Erie is blanketed with zebra and quagga mussels, the
latter blamed for this year's phosphate woes and the "dead zone" of the
lake. Waterfowl biologists theorize the surprising slump in the flocks of
scaup, or bluebills, is the result of the diving ducks eating the mussels,
which concentrate contaminants as they filter-feed Lake Erie's waters to
make them as crystal clear as a goblet of spring water.
Zebra mussells have escaped the Great Lakes as well. The major rivers such
as the Mississippi and lower Missouri have been introduced to the plague
of
zebra mussels, as have lakes both large and small.
Schools of small, round gobies have exploded in Lake Erie in the past
decade. The gobies feast on the exotic mussels, though they don't seem to
dent the population. The gobies are being blamed for a wave of diseased and
dying fish and birds in eastern Lake Erie, sickened by a virulent strain
of
type E botulism after feeding on gobies.
The most destructive of the non-native fish is the ruffe, which continues
its march to Lake Erie. First discovered in Duluth Harbor at the west end of
Lake Superior, the ruffe hopscotched to Lake Huron a few years ago and this
summer was discovered in Lake Michigan.
There is no doubt Lake Erie is next for the ruffe, an invasion that would
put the most vibrant population of yellow perch in the Great Lakes in
serious jeopardy. When the ruffe takes over, it pushes other fish, including
perch, out of the area. The shallow water of western Lake Erie is the
perfect habitat for the ruffe.
The invasive species continue to arrive from Europe in the ballast water
of
ocean freighters. The U.S. and Canadian reports say that measures to stop
the invasion, such as ballast-water monitoring and ballast-water exchange,
have not prevented the arrival of new aquatic organisms.
Even worse, the reports forecast it will take another 10 years to develop
and implement ballast-water management techniques that work.
A stumbling block is the economic impact of stringent ballast-water
standards that would result in a zero discharge of invasive species. In the
meantime, the losses keep piling up, the list of non-native organisms in
the
Great Lakes gets longer and the fishing continues to decline.

Todd, nice looking aquarium is this in your cubicle at work if I had an aquarium with me at work, I'd probably get nothing done of course, this would be really tough since I'm a house painter Harry Knaub

I must apologise for the following:

In all the malaya the has occured here in the past few weeks I have forgoten who sent me some tadpole madtoms! I feel terrible. Please come forward in an e-mail to me (bast_at_gis.net)

I will be posting photos of the tanks that several NANFA members have help with over the past couple of years. Advice and specimens have been invaluable. This group is made up of people that help to renew faith and hope in our own species.

Hi all,

Well it seems I was in for a little bit of a suprise. Not only is this blacknose dace (Rhinichthys atrarulus) a cool lil' fish... It seems to be picking at blackbrush algae (red hair algaes). Is this normal behavoir?

Are "dace" in general, good opportunists? Double bonus if so, as they're cool critters I had planned to keep anyway :)

It was a nice feeling to have a co-worker (also an aquarist) come in the cube yesterday and go "Wow! That fish was mostly plain... but now it's just plain cool!" as it's gotten more comfy and colored up quite a bit :)

You bet. They were opportunistic enough to swallow some of my smaller darters and also choke to death in the process.

Greedy little fish, they are.

Okay. So Least and Iowa Darters are out of the question. :)

Thanks Sajjad.

Here is an old joke, retold:

Two men are out on a froken lake ice fishing. One man had been out on the lake for over two hours and he hasn't gotten a single bite. The other man, just about a dozen feet away, had been on the lake for about half an hour, and he already had almost a bucket-full.

This disturbed the other man greatly, so he walked over to him and asked him, "Excuse me, sir, but I'd been out 'ere fer a mighty long time and I ain't caught nuthin'. How do you catch all them fish?"

The other man looked at him and said, "Mummmummhummmummhummhmummm."

"What did you say?"

"Mummhummmummhummmumnmunhumm," mumbled the busy fisherman.

"Sir, you got a speech impediment? I can't here a darn word yer saying!"

The fisherman pointed his finger up, indicating to wait a minute. He pulled and reeled in his line and pulled and reeled in, and he cuaght another fish.

"OK, darn it. Either tell me now or else," said the angry 'amateur'.

As the 'expert' removed the fish from the hook, he looked at the unfortuate man standing beside him. He put the fishing pole down and took a large wad of something out of his mouth.

"You have the keep the worms warm," he answered.
