Sustainability overview

Farmed prawn accounted for over 40% of the global consumption of prawn in 2005. Tiger prawn is the most commonly farmed species in south-east Asia and 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: The conversion of ecologically sensitive habitats such as mangroves to pond areas; 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 South East Asia. 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.

Biology

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.

Production method

Pond system, semi intensive

Prawn /shrimp are farmed in saline/brackish water ponds of various sizes and intensities in many countries of SE Asia, either in coastal areas or inland within or outside the intertidal zone. Intensive pond farming has a higher stocking density of prawns
