Surrogate Parents for Endangered Trout

Using the work of Japanese scientists who wanted to boost the population of bluefin tuna, Idaho researchers will begin experimenting with “surrogate broodstocking” to see if they can use the techniqe to replenish stocks of sockeye salmon and other endangered salmonids. “The new method is ‘one of the best things that has happened in a long time in bringing something new into conservation biology,’ said University of Idaho zoology professor Joseph Cloud, who is leading the U.S. government-funded sockeye project.” Lauran Neergaard of the Associated Press.

    Someone needs to explain to me why this is a valid improvement for fish conservation. You stil need live sperm: it is not like greenback DNA taken from a museum sample, it requires a live fish. And if you have live sperm chances are you have access to live eggs, which means the species does exists alive. So why not just breed them? This is a cool trick and technique but arguing it is important for trout conservation is, to me, self serving self promotion that is not based on reality.
