Sustainability overview

GlobalGap certification standards for the production of warm water prawns defines and enforces production standards to address many issues of concern. Intensive prawn/shrimp farming is associated with a number of negative environmental impacts which are of concern, these include: The use of unsustainable feed resources ; the risk of salinisation of freshwater bodies; discharge of organic matter and nutrients leading to environmental changes; 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. They are also concerns regarding the current regulatory framework and level of enforcement for aquaculture production in some areas.

Feed Resources

Criterion Score: 0

Feed ingredients, both marine and terrestrial for GlobalGap certified prawns are traceable and encouraged to be responsibly sourced although this is not a requirement.

info

Environmental Impacts

Criterion Score: -4

Whiteleg prawn have a number of environmental issues associated with their production, many of which are mitigated or limited by the GlobalGap certification standards. These include: freshwater impacts and use; habitat impacts; pond discharge, escape risk and disease outbreaks and predator control.

info

Fish Health and Welfare

Criterion Score: 0

Welfare standards are included within the GlobalGap criteria. Widespread disease outbreaks however are known for this species.

info

Management

Criterion Score: 2

Criteria for certification to the GlobalGap standard meets the requirements for regulation of production, overall they are effective however major disease outbreaks are still occurring.

info

Production method

Pond system

Prawn /shrimp are farmed in saline/brackish water ponds of various sizes and intensities in many countries, either in coastal areas or inland within or outside the intertidal zone.

Biology

The king prawn (or whiteleg prawn, white shrimp) belongs to the largest of the prawn and shrimp family, the Penaeidae. It is a native species of the Eastern Pacific coast. 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 7 months. They can live up to 2 years in the wild although farmed prawns are usually harvested at 6 months.
