Growing Bigger Trout Through Sterilization
Jim Brewer of the Daily Progress reports that fish hatcheries can save time and money by producing sterile trout that grow bigger faster. He also states the benefits of this manipulation.
An additional benefit is that there is no danger of a stocked species of trout establishing a population or crossbreeding with any wild trout. In numerous streams across Virginia we now have wild brook trout, wild rainbows and wild brown trout that are doing quite nicely. Stocking sterile fish in the streams holding wild populations would increase the recreational opportunities for anglers while reducing pressure on wild populations and with no threat to the wild trout fishery.

[...] Tom Remington recently wrote a blog entry on sterile fish and their potential to grow faster and perform better than fertile hatchery fish, which allocate a portion of their growth potential toward reproduction. The topic is a very interesting one, especially since sterile hatchery fish do not threaten wild populations with the potential for interbreeding and compromising genetic integrity. [...]
