    Re: Triploid Trout - What is it?

    I was listening to Denis Pearse this AM on KNCO and he interviewed the woman who manages Englebright Lake. She said her pen raised trout that were bought in November from the Lassen Fishery have essentially tripled their size/wt. (2# to 6#) from Nov. to now. Must be triploids I expect... I fish that lake often since it's close to home but mostly just catch small planters which I return to the water. Would be great to hook up a decent size trout there.
    Thanks, Mark

    Normal trout suffer high rates of reproductive stress related mortality. It is the period after normal trout reach sexual maturity (3 or 4 years) that triploids out pace normal trout in growth potential. Triploids don’t waste energy on reproductive tissues (females don’t anyway) and can live longer and grow to awesome size if there is enough food. The best triploid lines are all female that never develop an interest in reproduction.

    Triploid kokanee that could reach 7 or 8 years (and huge size) were an experiment that did not pay off as far as I know. Too bad, just think of an eight pound kok on your line.

    Most of the manmade impoundments (reservoirs) have outlets that are screened off. This prevents any fish from migrating down stream. I would think that during an overflow, some might get down the river.

    I wonder how old a trout has to be before he looses interest in spawning. I've read that triploids can live for up to eight years.

    Yeah, triploid trout are sterile, but the brood stock maintained to produce them obviously are not sterile. Triploidy is induced by heat or pressure shocking the fertilized eggs.
