A representative of the Trout River Fish Company in Jacksonville, Florida, shared a photo of a tiger shrimp they say is a foot long and weighed half a pound. It was caught Thursday in the St. Johns River.

Asian Tiger Shrimp  are two to three times the size of a typical white shrimp and are considered  a serious nuisance to the river.

In recent years, the southeast United States has become their breeding ground.  Female Asian Tiger Shrimp lay one million eggs over their 14-month lifespan, and northeast Florida's warm, sandy bottom is an attractive home.

We reported in 2013 about this threat to local shrimp.
