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 .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: 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 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.

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.
