The Jullien's golden carp (Probarbus jullieni) is a species of endangered freshwater ray-finned fish in the family Cyprinidae found in Southeast Asian river basins.

The Jullien's golden carp was named by French paleontologist, ichthyologist, and herpetologist Henri Émile Sauvage.

Some defining characteristics of fish in the Crypriniform order is that they are generally found in freshwater, are ray-finned, and lack proper spines.

Two common types of fish found in this family are carp and minnows, both of which are characterized by their convex dorsal and ventral surfaces, lack of adipose fin, and thin lips.

Adults migrate upstream during the dry season to form spawning communities in deep pools of low water.

[10] Habitat Historically, this fish was found in the Mekong, Irrawaddy, Chao Phraya, Meklong, Pahang, and Perak River Basins of Southeast Asia, specifically in Thailand, Laos, Cambodia, Vietnam, Myanmar, and Malaysia.

[12] As of 2012, this number has been greatly surpassed and there are now approximately 2.5 million metric tons of fish, including the Jullien's golden carp, being harvested per year.

This means that little effort is being made to preserve the endangered species of fish they are breeding, such as the Jullien's golden carp.

Due to its cost, the Jullien's golden carp is only commercially served in a select few restaurants in Southeast Asia, specifically in Malaysia and Myanmar.

This market encourages local fisherman to go into the red zone, an area of wildlife conservation where the public is only allowed to engage in small-scale fishing.

However, the Burmese government stated in March, 2014 that the Jullien's golden carp's special protection program makes fishing for them from February to April illegal.

Since the Irrawaddy River Basin is one of the last areas of refuge for the Jullien's golden carp, the recent creation of the Myitsone Dam in Myanmar is further threatening its existence.

Since the Jullien's golden carp has a relatively large population in the Mekong River, the consequences of this dam could be disastrous.

Thus, although in the short-term these dams will provide much economic stimulus, Lao PDR is estimated to obtain $2.5 billion a year in revenue.

Industries in Southeast Asian have expanded without proper water treatment facilities, causing its rivers to be oxygen-poor for much of the year.

Although the agriculture techniques in Southeast Asia are becoming more modern, this increase is cash crops is coming at the expense of the regions other large industry: fish.

[15] Many Southeast Asian countries have research groups that are creating their own studies to show the negative effects that dams have on the environment, specifically water and fish.

These research groups, including the one listed above may be regionally based, but they are part of the internal effort to stop environmental degradation.

This shows the increasing trend of regional research groups partnering with NGOs to gain more power and create more change.

[14] Regional and national efforts In Bandar Tenggara near Desaru in Johor, Malaysia, there is a project called Vita Tenggarra that centers around the breeding of threatened or nearly extinct fresh water fish found in the river basins of Southeast Asia.

Although the initial purpose of this conservation fishery will be to breed fish like the Jullien's golden carp simply to preserve them for future generations, the end goal of this project is to make food aquaculture an important economic activity in the region.

Thus, national efforts such as the Vita Tenggarra project may be economically motivated, but their end goal is to create both a sustainable industry and increased environmental policies.

Burma's President Thein Sein admitted on October 1, 2011, that he was establishing this commission and related study due to public pressure both internally and externally.

Also as of 2011, the Burmese government has halted usage of the US$3.6 billion Myitsone Dam project in the Irrawaddy River due to environmental concerns.
