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.
Intelligence
The social and environmental improvements – in combination with job-generating foreign investment – have led to wide acceptance of shrimp farming in Bangladesh.
Health & Welfare
Development of integrated aquaculture systems could assist in improving environmental quality and changing public perceptions of aquaculture.
Aquafeeds
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.
Health & Welfare
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.
Innovation & Investment
Optical scanning and associated imaging software reduces stress and increases accuracy as compared to traditional techniques for shrimp measurements.
Responsibility
At higher stocking densities, the application of all feed via feed trays often results in feed being dropped outside and/or underneath the trays.
Health & Welfare
Researchers studied the nature of muscle necrosis in shrimp by sampling infected shrimp from local ponds and challenging healthy specimen with filtrates from the diseased shrimp.

Those charged with determining the underlying cause of a disease outbreak have a wide variety of detective tools at their disposal.
Health & Welfare
Shrimp survival, weight, yield and feed conversion were better in farm units that operated with settling chambers for solids removal than in units without.
Health & Welfare
Combining biofloc technology with bio-secure modular shrimp culture can make operations more sustainable and economically viable. For optimized biofloc production, lined ponds and reservoirs and high stocking densities are essential. Paddlewheel aerators keep dissolved-oxygen levels high.

One of the largest shrimp maturation operations in Ecuador is working with five major shrimp producers to improve growth rates.

The emerging disease Early Mortality Syndrome has caused large losses among shrimp farmers. EMS is characterized by mass mortalities during the first 30 days of culture.
