Sea Lamprey don't feed on fish eggs. Native lamprey (Brook, Chesnut, etc.) might, though. |

It is the sea lamprey. There have been numerous stories about hem for years on Nat Geo and other channels like them. I know the lamprey has been in the Great Lakes since the opening of the locks to allow ships to get into Lake Erie. However, it seems like the last show I watched about them showed how they were neutering all the males they could catch and letting them go back into the wild. The idea being that they would be sterile and would lessen the reproduction rate. They were catching them in the streams and tributaries where they were feeding on pike fingerlings or something like that.
All I know is that they are destroying the fisheries up there...at least that is how it was presented on the programs I have seen.

Sea lampreys have been in the Great Lakes since the opening of the Ship canal around the Niagra Falls. I believe that is how Alewive gto there also. Sea Lampreys feed by boring a hole in the side o the host fish and sucking out the juices (blood) (vampires??). Pegsguy has it right on the efforts to control them. Never heard of neutering and releasing them to control them, I do know that the use of sterilized male mosquitos has helped in their population control. It works because a female mosquito only breeds once per cycle and if the he-bug is shooting blanks, she lays no eggs that time around (or the eggs are sterile).
Yes there are squawfish in the Colorado river but never so many as in the Columbia river system. They were the apex predator until other types of fish were brought west. The Colorado river system is long but tiny compared to the Columbia System, not even half the size of the Yakima. I think pretty much all of the native species of the lower river are endangered, whereas the dams and competition did not seem to bother the Columbia fish much, it has made things hard for all of the native fish of the lower Colorado. I have only seen a squawfish in the aquarium in the Cabelas in Glendale, AZ. |

Orange Texas Sea Lamprey are almost totally parasitic feeders. They only suck out other fish's blood and other fluids. Alewives, however, are big consumers of fish eggs, especially Lake Trout eggs, due to the locations that Lake Trout typically spawn. |

Guess it is because no one likes them either.
Cabelas probobly has the Coroado River Pike Minnow in the Aquarium 'cause that is the only way most of us will ever see this rare and endangered fish, which does have a sort of fpike like profile for its body. |

Were you joking? "Rare and endangered?" They are neither! And who wants to see them? They are ugly, gross fish. Come fish the Spokane river for 20 minutes then tell me they are rare! There are millions of them here. I still say kill em' all! |

Sorry CQ;
I guess that I must have hijacked it by including it with other invasive fish that should have a bounty on them.
Sorry,

Never having seen a Squawfish, I wouldn't recognize one if I caught it but CQ's pic doesn't look the least bit like a pike. At least the ones I have caught! Tom |

They do only a little Tom. Just because of their long body. But other than that no they don't. |

I think what he means is that Pike Minnows aren't that wide spread, although they cause problems where they live. I personally had never seen one until you brought up this topic. |

Like I said before, on the huge Columbia river system, they have obviously adapted well to the changes in the river system, the fish native to the Co;orado have not. Before dams created reservoirs, The Colorado river ran huge variations in flow. They river was usually relatively muddy and warm. Now the river has huge coldwater tailwater areas that are totally alien to the native species as well as a huge new set of predators; bass, catfish and stripers mainly. Every fish "native" to the lower Colorado River (and Arizona) is or has been on the endangered species list. This is totally different than the northern species to which you refer.
Fisherfanatic, you will probobly never see one unless you come west. I have spent very little time on the Columbia River system and didn't see any then, as I said, the only ones I have ever seen were the endangered "colorado River Pikeminnow" at the aquarium at the local Cabelas. Most people will never see one down here...Whole 'nother subject from CQ's area.
Always wondered why they were called "squawfish"? Squaw is algonquin ( I think) and means "woman". |

If it is the state rule to kill the invasive species on the spot, then one should just do so. Sure enough first time I've seen it done, I was sick to my stomach, but people were only following the rules. |

It is not the state rule to kill Squawfish. But there is a bounty in certain areas of WA and ID. They are destructive to other fish populations that are of recreational and commercial value. Squawfish really are just a nuisance. |
