The Telegraph over across the pond in the UK is reporting that Japanese scientists have been successful at breeding trout from salmon
. What is the ultimate goal of these piscatorial alchemists? They eventually
hope to turn mackerel
into tuna, thereby assuring a spicy tuna roll in every pot for years to come.
The embryos they produced developed into adult trout of both sexes, capable of producing either trout sperm or eggs. These were then combined to produce healthy trout offspring.
The scientists say the technique could be used to preserve threatened species if traditional methods such as reducing fishing, breeding in captivity or restoring their habitat fail.
However, the real target of the work is the bluefin tuna – an important ingredient in Japanese sushi and sashimi.
