I ran across an article several months ago regarding Dr. Lawrence's process and found it to be very interesting, and it was developed right here in the Great State of Texas! Not only does it address the issue of a food source for the world, it will help in creating much needed jobs in this tough economy. Thanks to the folks at the NorthTexas e-News for tossing out the story once again, and we're looking to post new information about the SIRSFT process as it comes available.

Kudos to Dr. Lawrence and his staff and the folks over at the AgriLife facility at Texas A&M! Gig 'Em!!
The patent-pending technology, known as super-intensive stacked raceways, was created by Dr. Addison Lawrence at the Texas AgriLife Research Mariculture Laboratory at Port Aransas, who says the system is able to produce record-setting amounts of shrimp. "We're able to produce jumbo size shrimp, each weighing 1.1 ounces, known as U15 shrimp, which gives us world record production of up to 25 kilograms of shrimp per cubic meter of water using either zero water exchange and/or recirculating water," he said. At this rate of production, Lawrence said commercial shrimp producers will have the potential to vastly increase their profit margins.
Lawrence is convinced the indoor system will decrease this country's dependence on foreign shrimp and could even help alleviate world hunger. "Order a plate of shrimp at any U.S. restaurant, even along the coast, and chances are you'll be served shrimp farmed in Southeast Asia and frozen two to four times before it got to your table," Lawrence said. "That's because the U.S. imports about 90 percent of the shrimp it consumes, with a value of about $4 billion annually." In addition to contributing to a foreign trade deficit, imported shrimp also bring with them environmental and quality control issues, he said. "They are grown in open ponds and treated sometimes with antibiotics banned in this country, creating a negative impact on wetlands and human consumption," Lawrence said.
"Simplicity is the key here," said Lawrence. "Some of history's most creative, innovative inventions are based on very simple logic. Keep it simple." But the results of these simple tanks - the amount of shrimp that can be harvested - are astounding, Lawrence said.
"These tanks require stringent control and supervision, 24/7 monitoring with computers tracking the shrimp," he said. "But properly run, these systems can produce up to 1 million pounds of shrimp per acre of water, or two acres of land per year," he said "That's far superior to traditional shrimp farms in the U.S. that can produce only up to 20,000 pounds of shrimp per acre of water per year. In tropical countries that have year-round growing seasons, they can produce up to 60,000 pounds of shrimp per year." Developing the stacked raceway system is the culmination of Lawrence's 50-year career in aquaculture, he said. Along the way he's developed various components of the new system, including the patent-pending feed (co-inventor) for growing the shrimp, the closed water system using zero exchange and recirculating, a unique raceway bottom design and aeration system and other technologies. The vision for his creation includes stacked raceway facilities near major metropolitan areas throughout the country, producing live, fresh, never-frozen or fresh-frozen shrimp to be available every day of the year. "Most Americans have never tasted fresh shrimp," he said. "There is a huge demand for high-quality shrimp. At a nearby IGA supermarket, we test-marketed shrimp produced in these raceways and they sold out in a matter of hours. They would surely bring premium prices at supermarkets and restaurants in New York, Chicago, Las Vegas and other large cities. But more importantly, these systems could provide the protein that a booming world population desperately needs." Lawrence said that the world's population is expected to increase significantly in the next 20 to 30 years.
The world's first commercial application of Lawrence's stacked raceways will break ground just miles from his office in Port Aransas, according to Kemp.
Lawrence said based on high growth rates and high survival and production levels, economic data shows an estimated rate of return of 25 percent to 60 percent. "There are no disease problems; it's biosecure. So, with predictable high internal rates of return, the system is economically viable. But the best part is, it's totally organic with high-quality protein available every day of the year."
