How cold does it have to be before shrimp catches drop off in the winter?

Amy Hotz

According to the N.C. Shrimp Fishery Management Plan, winter water temperatures in North Carolina sometimes are lethal for white shrimp, which is the type of shrimp mostly found in waters of the southern area of the state.

White shrimp mortality has been reported at water temperatures of 46 degrees and lower, with total mortality occurring at 37 degrees or lower.

According to the National Weather Service’s Wilmington office, the gauge at Ocean Crest Pier gauge had water temperatures in early January hovering around 44 to 45 degrees for an extended period.

Most recently, it’s been about 46 to 47 degrees. Some inland waterways, including the Intracoastal Waterway, will have colder temperatures..
