> 2014 lobster value: $0.35 billion
> Pct. change in lobster export value (2013-2014): 43.5%
> Lobster as share of total state exports: 12.7%

While some of the most valuable exports in each state are unusual, it should surprise few that Maine’ is the lobster.

That was a significant increase from the $243 million worth of lobster exported by the state in 2013. One reason for the increased value of the exports may have been the skyrocketing price of lobster, which rose by nearly 80 cents a pound from 2013 to 2014.
