Biology and Species Information

Pangasius fish, also known as shark catfishes, are a genus of medium to very large freshwater fish native to South and Southeast Asia. The Pangasius genus is one of two extant genera in the family Pangasiidae, the other being Helicophagus.

Habitat and Distribution

Pangasius fish are found in large rivers and estuaries, including the Mekong River, Chaopraya River, and Chao Phraya. They are a traditional fish on the menu in countries such as Vietnam, Thailand, and Cambodia. Pangasius fish have been replaced by aquaculture in recent years, especially in Vietnam and to a lesser extent in Thailand and Cambodia.

Physical Characteristics

They have comparatively giant eyes and two pairs of barbels, higher shorter than the decrease. The fins are dark gray or black, and they have six branched dorsal-fin rays. They have gill rakers that are usually developed.

Life Cycle and Reproduction

Pangasius fish have a life cycle that includes spawning, fry, and maturity. Sexual maturity is reached at around two years of age. In captivity, pangasius fish can reach sexual maturity at a younger age. Pangasius fish are fecund, with females producing up to 1.5 million eggs per year.

Pangasius fish have adapted to the annual monsoon flood cycle by using upstream refuge and spawning habitats such as rapids and sandbanks. They are benthopelagic, meaning they live near the bottom of the water column.

Overall, Pangasius fish are a popular freshwater fish that are known for their silver, flat, skinless appearance. They are also commonly referred to as river cobbler, striped catfish, and iridescent shark.

Aquaculture and Environmental Impact

Farming Practices

Pangasius fish, also known as basa, tra, or swai, are farmed in the Mekong Delta region of Vietnam. The farming practices used to cultivate these fish have been a topic of concern due to their potential environmental impact. The siting, design, and construction of pangasius farms can have a negative impact on other users and the environment. However, the Aquaculture Stewardship Council (ASC) has developed global standards for sustainable pangasius farming that ensure responsible use of land and water resources.

To ensure the quality of the fish, farmers follow strict quality control measures, including monitoring pH levels, water temperature, and oxygen levels. The fish are raised in cages in the Mekong River, which provides an upstream refuge during the annual monsoon flood cycle. This allows the fish to thrive in their natural habitat while also protecting the environment.

Nutrition and Consumption

Pangasius fish are a good source of protein, iron, calcium, and omega-3 fatty acids. They have a delicate texture and mild taste, making them a popular choice for seafood lovers. Pangasius fish are also safe to eat and meet the food safety standards set by the ASC.

Consumers can find pangasius fish in supermarkets in the UK and Europe at an affordable price. This makes it a popular choice for those looking for a healthy and sustainable seafood option. However, there have been concerns about fish fraud and mislabelling of pangasius fish as more expensive fish, such as cod or patin. To combat this, packaging and labelling regulations have been put in place to ensure that consumers are getting what they pay for.

Market and Trade

The pangasius fish market has grown rapidly in recent years, with Vietnam being the largest exporter of pangasius fish in the world. The sustainability of the sector is important as it is threatened by the concomitant increased environmental pressure. The ASC has moved forward to ensure that environmental impacts of pangasius farming are minimized.

However, the growing cost of inputs and reduced farm-gate prices of the fish have put pressure on the industry. It is important for the industry to balance economic viability with environmental and social standards to ensure that pangasius fish remain a sustainable and affordable seafood option.

Environmental and Ethical Considerations

The environmental impact of pangasius farming has been a topic of concern due to its potential pollution of water resources and the use of fishmeal and antibiotics. However, the ASC has set standards to ensure that pangasius farming is sustainable and does not have a negative impact on the environment. The feed supply chain is identified as a hotspot for improving resource use efficiency.

In addition to environmental considerations, social standards are also important. The ASC ensures that pangasius farming meets social standards, including fair labor practices and worker safety. This ensures that the industry is not only sustainable but also ethical.

Overall, pangasius fish is a safe, healthy, and affordable seafood option that can be enjoyed without causing harm to the environment or compromising social standards.
