So a large Carp will eat as much as say 4 small ones.... so having larger fish in the lake will cut down significantly on the amount of small fish that its able to support. |

any existing eggs, smaller fish would soon re establish themselves.

you are always going to have some small fish but if they are managed then its not a problem... i dont know how you would get rid of them all together as it was probably birds that carried eggs there in the first place and would probably do that again. |

Rusky wrote: What a load of crap. Going by your theory if you leave the big ones alone and they breed, then you have more smaller fish in the long run and your back to square one with the problem of juvenile fish. However, koi are sexually mature at a young age and they too also release many eggs, BUT not as much as say a Big carp. A 8kg carp may release say 8 times more eggs then a 1kg koi, no?
Eliminating the largest koi carp, then moving onto the smaller fish would be the right thing to do. |

NEVER be eliminated.
Now for the 64K question ..... Do you ALWAYS kill any koi landed, as
the law states you must ? |

yep and DoC know they missed the boat on that a LONG time ago, im surprised people think that they are doing their bit by killing Carp and its going to help out! :lol: its not so why bother. I think that answer just answered your last question.... |
sbeehre wrote: do you? its pretty common knowledge that Carp are only a problem if they are left to breed and breed and breed in an enclosed waterway! if they are managed accordingly the impacts are minimal. |
