News from northern Florida
It's been brutal here. In the first part of January you may have
heard that it got cold here. Now it gets cold here every winter, and it even drops below freezing a few evenings each year, but we aren't prepared for it to keep on going for days and days, over a week! Granted, it got well above freezing each day, and no ice or anything ever formed on the pond, but it nailed a bunch of plants. Should be an interesting spring. One plant the cold didn't seem to bother is the duckweed. As a matter of fact, it even looks healthier, if that's possible. In any event, one of my "neighbors" said that next time he goes fishing he'll bring me a bunch of carp from the Suwannee. Seems they aren't very good game, though he swears they will clear my pond up right away, and he says he's done it before with another pond. Shoot, if they came from the Suwannee it doesn't seem like it would matter much if they wash back down there, and as long as they're free it won't bother me that much if I do wind up just feeding the otter. .. |

Our triploid grass carp keep local ponds totally clear of vegetation.
My koi and goldfish think duckweed is a great treat. Local carp could work well for you. A thought: Two can become more than two. Would one do? Jim |

A thought: Two can become more than two. Would one do? I need to make clear that what I know about fish could probably be inscribed on the head of a pin with plenty of room left over. I was under the impression that triploid grass carp were incapable of reproduction. But that's really neither here nor there, because I don't know whether they will be monoloid, diploid, triploid, quadloid, or whatever-loid. As a matter of fact, if someone held a bass in one hand and a carp in the other, I'd probably guess that they were two different kinds of trout or something. Whatever fish my "neighbor" gives me are going in the pond. (I put "neighbor" in quotes because while he does live next to me, his driveway is a good 1/4 mile away. I can't see his house, I only see him a few times a year, he's a trucker and is on the road most of the time anyway.) If two fish become more than two, I'll get some loaves to go with, feed the multitudes, change my name, and walk across the pond. .. |

Triploids are sterile. That is good. The Mississippi is in real
danger of being their conduit to the great lakes! Local carp will not be sterile. Two and become more. I don't know if that would be a problem. Jim |

I will admit that my last geography lesson was over 50 years ago, but does the Mississippi have a conduit into the Great Lakes? The head waters are in central Minn, can't be the Missouri, it heads west, the Ohio goes east. Does the now backward flowing Chicago river enter the Mississippi? Chip |

Does the now backward flowing Chicago river enter the
Mississippi? Point well taken. It has headwaters right next to the great lakes to the West, but the Great Lakes drain to the Atlantic rather than to the Gulf! I know the grass carp are working their way north and that folk are concerned about them getting into the Great Lakes. Maybe not by that conduit. I will have to take a look at the map again. Jim |

Wikipedia makes a remark...about the redirected flow. It does go to
the Mississippi, but that still does not connect the Mississippi to the Great Lakes. "The Chicago River is a river that runs 156 miles (251 km)[1] and flows through Chicago, including the downtown. Though not especially long, the river is notable for the 19th century civil engineering feats that directed its flow south, away from Lake Michigan, into which it previously emptied, and towards the Mississippi River basin."

Further data on the Mississippi, the Great Lakes and invasive species
A bit more reading suggests the Mississippi and the Great Lakes are
connected via Chicago and that there is discussion of re-serarating the systems to prevent the spread of invasive species Quite a learning venture. Here is what I found: Recently, researchers at the University of Illinois at Urbana- Champaign created a three-dimensional, hydrodynamic simulation of the Chicago River, which suggested that density currents are the cause of an observed bi-directional wintertime flow in the river. At the surface, the river flows east to west, away from Lake Michigan, as expected. But deep below, near the riverbed, water travels west to east, toward the lake.[8] All outflows from the Great Lakes Basin are regulated by the joint U.S.-Canadian Great Lakes Commission, and the outflow through the Chicago River is set under a U.S. Supreme Court decision (1967, modified 1980 and 1997). The city of Chicago is allowed to remove 3200 cubic feet per second (91 m³/s) of water from the Great Lakes system; about half of this, 1 billion US gallons a day (44 m³/s), is sent down the Chicago River, while the rest is used for drinking water.[9] In late 2005, the Chicago-based Alliance for the Great Lakes proposed re- separating the Great Lakes and Mississippi River basins to address such ecological concerns as the spread of invasive species.[10] |

===============
I may be wrong but duckweed grows in ponds and still waters, not rivers. If carp are from rivers, it wouldn't be part of their diet. Little shiny plastic lures aren't part of a trout's diet, yet they try to eat them. ;-) I'm sure any carp will taste most anything that plant-like (think lettuce or spinach some feed their koi) and go Yummy when they taste duck weed. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |
