William R. "Dickie" Odom has been raising shrimp in Greene County since 1999. His well is 650 feet deep and produces water with 5 parts per thousand salinity, as opposed to seawater, which has around 35 parts per thousand. The growing season for pond-raised shrimp in Alabama is anywhere from 120 to 150 days. Odom operates six ponds spread over two acres, and each pond produces between 7,000 to 8,000 pounds of shrimp a year. His average production is 35,000 pounds of shrimp annually. Harvesting usually starts in the first week of October.

 Odom said, "This year, we sold 26,000 pounds fresh shrimp to the public. In fact, some of the shrimp were still alive an hour before they were bought. The other pounds are sent off for processing. ...They are processed to be headless, or peeled and deveined. The shrimp are individually quick frozen."

"In each pound, there are 16 to 20 jumbo shrimp, and each one has an average length of six to eight inches."

"We harvest for four weeks, and during that we have three public sales. We sell our shrimp for $3 per pound. The business for fresh shrimp doubles every year, and we have to build into the future to meet that demand. ...Most of our customers have been primarily from Marengo, Greene, Sumter and Hale counties. ...One buyer...was a shrimp boat captain from Bayou LaBatre, Alabama."

Odom gets his shrimp from a hatchery in south Florida. "We get them specific pathogen free. The chance of them having the diseases from coastal regions is not impossible, but it is relatively slim to none," said Odom.

United States
Oregon--View Shrimp on a Treadmill Video



Dr. David Scholnick, a researcher at Pacific University, has invented and built an underwater treadmill to measure the activity of "jogging" shrimp for a set period of time at known speeds and oxygen levels. Scholnick says: "As far as I know this is the first time that shrimp have been tested on a treadmill and it was amazing to see how well they performed. ...Healthy shrimp [Penaeus vannamei] ran and swam at speeds of up to 20 meters per minute for hours with little indication of fatigue." To further challenge the healthy shrimp, Scholnick put a small "backpack" made of duct tape on the shrimp's back. With the extra weight and lowered oxygen, shrimp jogged for up to an hour. When sick shrimp were put on the treadmill, they showed elevated blood lactate levels after jogging. Lactate is produced during exercise as a by-product of metabolizing glucose. Infected shrimp are unable to remove it from their tissues efficiently and therefore did not recover from jogging as quickly as healthy shrimp.

Unbeknownst to Scholnick, Pacific University's director of online communications, Richard Sipe, spotted the film on the professor's faculty webpage. He uploaded it to Youtube.com, a popular video-sharing website, and before long the clip was enjoying incredible popularity. At last count, Scholnick's nimble crustacean had been viewed more than one million times and generated several spin-offs in which people added music or re-cut the footage to make it look as if the 5-inch-long shrimp is dancing.
