Farmed tiger prawn accounted for over 70% of the global consumption of the species in 2013. 99% of production comes from developing countries. Intensive prawn/shrimp farming is associated with a number of negative environmental impacts which are of concern, these include: Impacts on ecologically sensitive habitats; the risk of salinisation of freshwater bodies; discharge of organic matter and nutrients leading to environmental changes; the use of chemicals and therapeutics in production and the potential of disease transfer between farmed and wild prawns. Marine prawns are carnivorous requiring high protein inclusion on their diet, this is one of the most critical concerns regarding prawn farming as the supply of fishmeal and fish-oil being used is, in general not traceable to species level and is not certified sustainable particularly in SE Asia. However, there is a significant amount of International work being undertaken at present to address and improve feed production and sourcing. There are also concerns regarding the current regulatory framework and level of enforcement for aquaculture production in some countries. The rating provided applies at a country/regional level and MCS recognises there is a diversity of practices and producers of warmwater prawn, some of which may be working to improve their practices. In these exceptional cases MCS would encourage support of these producers provided, and only if, a commitment to improvement which ultimately leads to achieving a recognised production standard can be verified.
The tiger prawn belongs to the largest of the prawn and shrimp family, the Penaeidae. Its lifecycle may be divided into 6 stages or phases, from embryo to adult, which it completes in one year. The age of sexual maturity varies from 5 to 11 months. They can live up to 2 years in the wild although farmed prawns are usually harvested at 6 months.

Zero input systems
Farming prawn in low or zero-input production systems relies on the natural productivity of the surrounding environment to provide feed. Because of this stocking density of prawns remain low and there are far fewer negative impacts in comparison to other
