The commercial farming of shrimp first began in the 1970s, with the industry experiencing rapid growth in the time since to match the demands of the United States, Japan and Western Europe. Today farmed shrimp account for roughly 55 per cent of the shrimp produced globally, with annual production growing at around 10 percent. Together this makes it the most valuable traded marine product in the world, experiencing the highest growth rate of any aquacultural activity. Most shrimp aquaculture occurs in China, followed by Thailand, Indonesia, India, Vietnam, Brazil, Ecuador and Bangladesh. Being such a lucrative business, shrimp farming has had a positive impact on the economies of these developing countries. Furthermore, demand is set to continue its rise as the middle class rises globally. More recently, shrimp farming has experienced some shortfalls as an industry. Shrimp prices in 2015 plummeted by 15 to 20 percent in international trade compared with the first six months of 2014 as a result of disparities in supply and demand in the

USA, the EU and Japan. These conditions persisted until mid 2016, due to lower production in China as the result of disease. Now, shrimp prices remain low and relatively stable, fuelling demand in the EU and Japan, which could be good news for growth the coming year. As problems surrounding disease have become a prevalent concern for the shrimp farming industry, the following pieces aim to address this issue in discussing new products available on the market. The first discusses a new, concentrated form of organic selenium from Adisseo, which promises to deliver higher potential growth in shrimp whilst reducing the accumulation of sludge in the bottom of shrimp ponds. The second article directly addresses the issue of disease in discussing a natural health additive for shrimp feed that may decrease bacterial infection and increase survival rate in farming conditions.
