Sustainability overview

Farmed tiger prawn accounted for over 70% of the global consumption of the species in 2013. 99% of production comes from developing countries .Prawn farming in Madagascar takes place within a small number of large scale producers that all farm Penaeus monodon (tiger prawn) which is native to that country. The regulation of prawn aquaculture in Madagascar is more effective that seen elsewhere in other prawn farming countries, and as such a number of the issues of environmental concern are addressed. In general intensive prawn/shrimp farming can be 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 prophylactic and unregulated 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. However there is a significant amount of work being undertaken to address and improve feed management at present.


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 parts of the world, either in coastal areas or inland within or outside the intertidal zone. Intensive pond farming has a higher stocking density of prawns and requires the use of inputs such as feed and therapeutants as opposed to traditional extensive systems.
