Inland Shrimp ChallengesInland Shrimp Production System

Genetically Improved Shrimp

Critical research is being carried out to improve shrimp growth and survival at high stocking densities through the application of selective breeding techniques.

Specialty Feeds

The breeding program is integrated with studies of shrimp feed formulations, with the intent to minimize feed waste. Exogenously supplied feed requires special formulations, unique physical characteristics, and a novel delivery system, and must be pathogen free.

Beneficial Microbes

Research is being conducted to characterize microbial community structure in a successful zero-exchange system. System microbes can enhance shrimp performance by stimulating growth and improving the shrimp's immune system.

The inland facility is completely isolated from the external environment to assure pathogen exclusion, and there are strict controls on human access. The biosecure system uses only specific pathogen-free shrimp as seedstock.

Recirculating Water

In order to maintain biosecure protocols, water exchange is no longer considered an appropriate management option because water can serve as a potent vector for shrimp pathogens. Water recirculation is accomplished by using a bead filter that reduces suspended solids and minimizes toxic metabolites. Importantly, the bead filter allows sufficient microbes to pass through to promote a green water system.

Because water is recirculated, water need only be added to the system to replace evaporative loss and water lost through backflushing of the bead filter. This produces a small amount of effluent that may be used to grow commercially valuable halophytes (salt-tolerant crops such as broccoli.)

High Quality Product

Shrimp produced in the biosecure system are nutritious and flavorful and can be grown to any size that the market demands. These shrimp will be free of both shrimp and human pathogens.

An important system attribute is the ability to grow shrimp away from the coastal zone where competition for resources is extraordinarily high. By siting facilities inland, producers will be able to reap the economic benefits of being in closer proximiity to feed manufacturers and their markets.

Economically Competitive

Using biosecure shrimp production technologies, shrimp growers will be able to provide to the market a high-quality product at a competitive price. Importantly, shrimp grown in inland biosecure systems will not be exposed to the vagaries of wearher, so that a predictable product can be produced in a timely manner. An elaboration of the system is underway with commercial partners.

The success of this new technology is based on exploiting the synergistic interactions among system inputs (shrimp, feed, microbes) to maximize productivity and profitability. With this approach, shrimp farmers will be able to produce high quality shrimp products with minimal adverse environmental effects.
