Interpretive Summary:

Technical Abstract: Interest in enclosed biosecure superintensive shrimp production systems has grown in response to disease problems, environmental concerns and an imperative to increase system productivity for increasingly competitive markets. The US Marine Shrimp Farming Program has maintained a long-term research and development focus on the design and operation of next generation systems for domestic shrimp production. The present report summarizes recent consortium accomplishments and explores the outlook for commercialization of these technologies. In Mississippi, simple raceway designs based on a central airline to maintain particulate suspension and dissolved oxygen levels have been evaluated. In a comparison of indoor systems (at low and high light levels) to an outdoor direct sunlight system, growth rates averaged 0.9, 1.0 and 1.5g/wk respectively. In South Carolina, pilot scale minimal exchange systems have been operated over the past few years based on a combination of blower, aspirator and paddlewheel aeration and circulation. These trials have demonstrated technologies for maintaining temperature year round. In recent direct stocked trials, production of up to 3 kg/ m2 was demonstrated with survival ranging from 55 to 71% and harvest size of 14.6 to 17.1 g in 137 days. Data on water quality and microbial communities in these highly eutrophic systems will be presented. In Hawaii, a raceway system using aspirator aeration and bead filtration to maintain a green water environment was developed. Three trials have been conducted with increasing stocking densities from 100 to 300/m2. In the most recent 85-day trial juvenile shrimp (2g) grew to a harvest weight of 19.9g with a growth rate of 1.47 g/wk. Productivity of the system reached 5.2kg/ m2 at a survival of 86.3%. All of these systems are based on high output, minimal water usage and enclosed raceway designs which assure biosecurity providing excellent potential for application in nontraditional and/or contaminated environments. The demonstration trials described in this presentation, along with supporting research on breeding, microbial dynamics, feeds, engineering, financial feasibility and marketing, have brought these technologies to the point of commercial implementation. Peri-urban application of these technologies in the United States could offer opportunities for development of integrated marketing initiatives to improve the outlook for financial viability.
