I have heard that the Male Lake Trout that has been planted in a lake is basically un-fertile. THis inhibits the natural reproduction due to the unfertile male fertilizing eggs from a natural Lake Trout. Keeping the Natural fertile Male from depositing on the eggs.


Is this True? and is there something to back this up?

mmm... I never have heard of this. Lake trout are natural to begin with. Most hatcheries will "milt" the trout for eggs and grow them and plant them back into different environments. So you see, they really are not a hybrid. A hybrid would be the combination of 2 species and as far as I can find, most of these are fertile. Splake is a good example of this.

"Lake trout are the largest representatives of a group of fish known as char and are closely related to Dolly Varden, brook trout and arctic char.

The lake trout has been hybridized with the brook trout to produce a fertile hybrid called a “wendigo” or “splake”."

If you are asking if lake trout that have been raised in a hatchery from milted fish are infertile, I have never found anything to support this. Maybe someone else can chime in.

This has been studied by biologists but very hard to confirm. Here is a link to a paper (rough draft) of some studies and evidence of Reproduction at Lake Michigan’s Mid-Lake Reef Complex. After reading the paper, you are going to find why it is so difficult to study.
