Growth Rings May Determine Lobstersâ€™ Exact Age, Claims Study
A recent research showed how age of a lobster can be measured by counting its rings. Yes, a team led by Raouf Kilada, a research associate at the University of New Brunswick, is of the view that just like in the case of trees, lobsters age can be determined by tracking down the rings.
It is believed that lobsters and other crustaceans, such as crabs and shrimp, have a tendency to grow one ring per year in hidden-away internal spots. "Having the age information for any commercial species will definitely improve the stock assessment and ensure sustainability", said Raouf Kilada, at a scientific conference in Portland. He was among over 100 lobster scientists from the U. S., Canada and Europe, to attend the conference.
For the research, the team examined lobsters, snow crabs, northern shrimp and sculptured shrimp, and noticed growth rings in the eyestalk. Apart from there, rings were also found in the so-called "gastric mills," in case of lobsters and crabs.
It has always been believed that lobsters could live to 100 years old, and with this new technique in offing, there are chances of proving the same in near future. The research was published in this month's Canadian Journal of Fisheries and Aquatic Sciences.
