According to World Bank, aquaculture output in 2015 was around 106 million tons of several fish species, crustaceans, mollusks and aquatic plants

Among them, shrimp is one of the most valuable groups of species. Consolidated data from FAO show that in 2015 shrimp farming produced almost five million tons. Looking at the data recently released at GOAL 2017, growth rate from 2006 to 2012 was of 4.8 percent and 4.2 percent from 2015 over 2014. Global figures may lead to the conclusion that the industry is flourishing everywhere, but that is not completely true.

The scenario is quite heterogeneous. Steady growth rate in the last five years is only observed in few countries like India and Ecuador. In some other countries we have seen erratic growth curves or stable production volumes like in Vietnam, Indonesia, Malaysia, Philippines and Mexico or even declining production volumes like in China, Thailand, Bangladesh, Myanmar and Brazil.

One of the main reasons for this unstable performance on the shrimp industry in many countries is related to diseases, which have been causing strong outbreaks and devastating several ponds and, extremely, affecting the economy of entire regions or nations. Taking into account the diversity of causative agents and the way diseases can be spread, there is no another way for farmers than learning how to live with the pathogens as close neighbours and being able to avoid the diseases to express.

Several measures have been taken by farmers in order to mitigate the risk of diseases. Traditional farms (large ponds, with no aeration, high water exchange and direct PL seeding) have been adapted to more intensive farms provided with water treatment systems, with low water exchange, in order to enable better control of water quality parameters, pond management and to ensure the quality of inlet water.

Additionally, using nursery facilities to stock bigger and more resistant shrimps in grow out ponds, seeding SPF larvae and utilisation of probiotics to ensure a good environment are becoming more and more usual.

Understanding the full picture of a shrimp pond and how the main factors interact is key to master aquaculture systems in order to optimise shrimp output. Therefore, the French based NEOVIA group, a global leading player in animal nutrition and health, stakes its aquaculture strategy on a comprehensive view of the value chain.
