Research continues in the global efforts to identify the cause of acute hepatopancreatic necrosis syndrome in farmed shrimp and find solutions to stop the major losses caused by its spread. 

Controlled by timers, automatic feeders should be placed in deeper areas of ponds and away from aerators. Overfeeding is rare during automatic feeding, and pond bottom quality is maintained through grow-out cycles. 

Since Taura syndrome virus was in the Americas when yellow head virus become pandemic in Asia, it is possible TSV prevented shrimp in the Western Hemisphere from infection by materials from Asia containing YHV. To test this idea, the authors evaluated the viral interactions in shrimp preinfected with TSV and then challenged with YHV. 

Authors evaluated how limiting dietary essential amino acids and long-chain polyunsaturated fatty acids would affect the growth performance of white shrimp raised in a zero-water-exchange biofloc system. The shrimp were fed diets with varied levels of fishmeal and fish oil and supplemented with soy products. 

Bangladesh shrimp farmers are adopting measures to improve quality to comply with international standards. A survey found that most farmers visually evaluated shrimp by checking size, weight and signs of disease before harvesting. 

In ongoing trials of greenhouse-enclosed intensive biofloc shrimp culture systems, the objectives of a 2012 study were to evaluate the performance of fast-growth shrimp fed a commercial diet formulated for high-density culture systems, and to further evaluate injector performance in the zero-exchange, super-intensive raceways. 

The final article in a series about a project in Brunei to develop technology for production of black tiger shrimp focuses on the development of advanced grow-out ponds and practices with enhanced systems for biosecurity, sludge removal, water reuse, energy efficiency, automatic feeding and mechanical harvesting. 

A large-scale integrated shrimp aquaculture park (iSHARP) project in Malaysia is approaching completion of its first phase. Biosecurity is a priority at iSHARP. The design of each unit allows individual modules or ponds to be “locked down” to prevent disease from spreading. 

Color can impact the price of shrimp, with dark red preferred in some markets. Research using colorimeters to quantify color in raw and cooked shrimp found that although shrimp raised on white or black substrates exhibited different coloration, total carotenoid levels were the same in all the animals. 

A cooperative project established to study the small-scale culture of the native shrimp Farfantepenaeus notialis in Cameroon aims to develop family- and community-level production in the region. 

Research at the Texas AgriLife Research Mariculture Laboratory is investigating ways to improve the economic viability of super-intensive raceways for shrimp production. 

The social and environmental improvements – in combination with job-generating foreign investment – have led to wide acceptance of shrimp farming in Bangladesh. 

Development of integrated aquaculture systems could assist in improving environmental quality and changing public perceptions of aquaculture. 

A study investigated the effects of storage temperature and duration on the quality of finished fishmeal fed to juvenile shrimp. Diets with 15 percent fishmeal were stored at 4 or 30 degrees-C for six months or 12 months. 

The quality of postlarvae supplied by a shrimp hatchery can vary considerably. Common myths, such as acceptance of low survival and insufficient concern for water quality, can contribute to lower animal quality.
