The live fish trade can refer to the live food fish trade (for human consumption) or to the ornamental fish trade (for aquariums). The fish can come from many places, but most comes from Southeast Asia. The live food fish trade is a global system that links fishing communities with markets, primarily in Hong Kong and mainland China. Many of the fish are captured on coral reefs in Southeast Asia or the Pacific Island nations.

Within the live food trade there are certain types of fish demanded more often by consumers, particularly smaller and medium sized fish. According to the book While Stocks Last: The Live Reef Food Fish Trade consumer demand has caused the fish captured on coral reefs to be the most valued fish in the trade. Consumers are important because they are directly purchasing these fish species at restaurants and stores. In addition to these types of fishes, many juvenile fish are used for the live food trade. There are also cultural and regional preferences among consumers, for example, Chinese consumers often prefer their fish to be reddish in color believing the color to be auspicious. These preferences inevitably affect the biodiversity of marine life making certain fish species rarer to find. The life fish food trade is a lucrative business. According to University of Washington Professor Patrick Christie, live fish caught for food export earns approximately $6000 a ton. To help support themselves and their families, fishermen in Oceania and Southeast Asia sometimes use illegal fishing methods. Although many feel the fish are worth the cost, a typical dinner can cost up to one hundred dollars per kilogram. The wholesale value on these fish is anywhere from eleven US dollars to sixty three US dollars per kilogram, meaning there’s a large markup and resale value. (Hong Kong alone is estimated to be about four hundred million US dollars a year.) Because this trade frequently uses illegal methods of collecting (using cyanide), there is no way to know for sure how much money is being made each year on live fish trade, although estimates conclude probably over one billion US dollars each year. As is often the case, consumers are willing to pay large amounts of money on rare and fresh fish. One 500 pound, polka dot grouper, estimated to be more than a century old, was hacked into fillets by seven kitchen workers in about half an hour, the Economist reports. It was expected to bring about $15,000.

The center for the Live Food Fish Trade is located in Hong Kong the markets consumers contribute $400 million to the estimated $1 billion of the trades global value. Total imports flowing into Hong Kong included 10153 metric tons, of which 30 percent was re exported to mainland China. Other major markets include Singapore, mainland China, and Taiwan. The primary suppliers of wild caught fish are Indonesia (accounting for nearly 50 percent of Hong Kong's imports), Thailand, Malaysia, Australia, and Vietnam. In Southeast Asia, Singapore alone consumes 500 tons of live coral fish a year. Many whose livelihood once depended on fishing or agriculture are realizing it is more lucrative to participate in illegal fishing activities. Community members who are not a part of the trade are affected by the activities of these illegal fishers. The cyanide fishers profit by taking away from everyone else’s trade and food. ‘If people were using poison and my take dropped to only a little, I would accept it,’ Puah said. ‘But I feel heartsick I catch nothing at all. I have not caught a big fish in a month so there’s no point in going fishing this afternoon.’” The live fish trade is part of this alarming ecological trend caused by the popular use of cyanide which is injected into the coral reefs to stun inhabiting fish so they can be easily caught by nets. It is estimated that since the 1960s, more than one million kilograms of cyanide has been squirted into Philippine reefs alone, and since then the practice has spread throughout the South Pacific. Although Asian markets are the primary buyers of live reef fish for food, the recently created U. S. Coral Reef Task Force has concluded that the U. S. is the primary purchaser of live reef fish for aquariums as well as eclectic jewelry. The harm upon the reefs is coming full circle and having a social impact through the limited fish stocks. As fish are depleted from these fishing techniques, the fishermen are having a more difficult time feeding themselves. Additionally, the use of explosives may be used as a fishing technique in the live food fish trade. While the majority of these fish do not survive the blast of such explosions, the remaining fish that are only stunned are collected for the live food fish trade. The use of cyanide makes a stronger argument in that the more coral reef fish captured alive, the more lucrative the catch is for the fisherman. Live fish, according to the [WWF], fetch five times more than a dead fish.

In communities like those in the Philippines and Indonesia, people are participating in the live food fish trade because it is a source of income, or at least a source of temporary income. For some communities this is one of the few income generating opportunities. Along with the environmental, ecological, and economic consequences of this industry, there are serious health risks as well. Because of inadequate training and lack of quality equipment, divers, especially young men are in large risk of paralysis.

Because of the great profitability of this industry, there is a great incentive to identify sustainable practices. The Marine Aquarium Council (MAC) works to offer the hobbyist with a product that is certified as environmentally sound and sustainable. Additionally, the International Marinelife Alliance (IMA), The Nature Conservancy (TNC), and MAC are working with the Hong Kong Chamber of Seafood Merchants to develop standards for the live fish trade. The Hong Kong Seafood Merchants represent ninety percent of the buyers of live reef food fish in Hong Kong and have an extensive impact on collection practices.

In an effort to address the damage inflicted on coral reef eco systems and fish stocks, aquaculture is being utilized to reduce pressure on coral reefs. However, initial efforts to farm grouper have met with significant challenges. There are difficulties with fragile grouper seed that can make it more expensive than wild caught larvae, which can affect natural replenishment rates. Additionally, there are problems with finding suitable food, disease and cannibalism. Efforts are also being made in regards to the aquarium fish trade. Juvenile fish are being captured and raised specifically for the industry. However, there are debates as to whether this practice will affect replenishment rates. “The age of the juveniles is pivotal to the debate, harvesting of postlarvae from the water column is considered to have a much lower (negligible) impact on rates of replenishment than the removal of the larger juveniles from benthic habitats because the postlarvae have yet to undergo severe mortality”. If studies determine that the capture of juveniles is sustainable, it may help in mitigating the damage from cyanide fishing. Aquaculture production, specifically grouper rearing is rapidly expanding in Asia. From 1998 to 2001 the Indo Pacific countries involved in aquaculture; China, Indonesia, Republic of Korea, Kuwait, Malaysia, Philippines, Singapore, and Thailand witnessed a 119 percent increase in output. The explosion in this practice can most likely be attributed to the large profit margins that can be derived in very little time. It is estimated that the majority of farms after annual returns can be paid back in less than one year. In comparison to other species of fish such as the Milkfish, the Grouper, because of high demand is able to garner high rates of return, in order to earn 1,000 dollars a grouper farm would only have to raise 400 kilograms in contrast to 5,000 kilograms of Milkfish.
