Sustainability overview

Pangasius farmed to GlobalGap certified production standards is a better choice to make for this farmed species. The GlobalGap certification addresses a number of issues of environmental concern, the auditing of which requires farm inspections and standard enforcement. There are a number of issues of environmental concern associated with production, these include: habitat alteration; freshwater impacts; nutrient and organic pollution; escapes; interactions with local wildlife and enforcement of regulations. Pangasius is a an omnivore and as such is not heavily reliant on marine proteins and oils to form part of its diet, however the fish used to produce the feed is currently not certified as being responsibly managed or sustainable. It is only by sourcing certified pangasius that you can be assured that the issues of critical environmental concern are being addressed.

Feed Resources

Criterion Score: 1

Pangasius are a fed species, requiring a commercial diet containing fish and vegetable proteins and oils. Feed for GlobalGap certified Pangasius is traceable but it is not required to be certified as sustainable or responsibly sourced. Pangasius require a low amount of fishmeal and fish oil in their diet making them a net protein producers rather than consumers.

info

Environmental Impacts

Criterion Score: -4

Pangasius have a number of environmental issues associated with their production, many of which are mitigated by the GlobalGap certification standards. These include: freshwater impacts and use; habitat impacts; chemical use, escape risk and disease transfer risk. However there are still issues that need to improve - limits on discharges to the surrounding environment and the use of lethal predator control.

Fish Health and Welfare

Criterion Score: 1

GlobalGap standards include requirements for fish welfare and humane slaughter.

info

Management

Criterion Score: 2

Overall the management of pangasius production is evaluated to be only partially effective. There is no Strategic Environmental Planning in place in the area that incorporates pangasius farming, there are regulations and/or certification criteria in place to cover the environmental impacts of production although these are assessed to be only partially effective as farm discharges have no limits and lethal predator control is permissible.

Production method

Ponds

Farming in open net pens in river systems allows for interaction with the surrounding environment and, as such, has to be managed in such a way as to minimise negative environmental and ecological impacts.

Biology

The group of freshwater fish known as catfish are captured from the wild or farmed for food and displayed in public aquaria dependant on the species. This farmed species natural habitat is medium to large rivers in Asian countries such as Vietnam, where they can grow up to 44kg.There are omnivores, feeding on a diet of other fish, vegetable matter and crustacea. Pangasius bocourti is one of the most important farmed species in Vietnam.
