Cyanide fishing is a specific method of collecting live fish, mainly for use in aquariums, which involves spraying a sodium cyanide mixture into a habitat in order to incapacitate the fish there. This practice affects not only the target population, it also has negative and damaging effects on many other marine organisms , including coral and ...
Cyanide fishing originated in the Philippines in the 1960s due to the growing market for aquarium fish in North America and Europe. [29] This method of fishing is done by squirting cyanide, a poison, directly into crevices of the coral reefs. The cyanide quickly stuns the fish, making the fishermen's job much easier when catching their targeted ...
The live fish trade for food sees the use of cyanide fishing to capture fish. [5] It has also had a direct impact on leopard coral grouper populations. This species is slow-growing, and its exploitation has been linked to localized decreases in average body size. [90] The ornamental fish trade also uses cyanide fishing to capture live fish. The ...
Cyanide fishing was thought to be used by perhaps 4,000 individuals as of 2013. [8]: 14 A USAID study estimated that LGUs lost 3,000-9,500 MT of fish to IUU activities each year. [8]: 16 The live fish trade for food sees the use of cyanide fishing to capture fish. [9] It has also had a direct impact on leopard coral grouper populations.
Divers without experience may come in direct contact with cyanide, causing death. Estimates show that since the 1960s, over a million kilograms of cyanide have been squirted into the coral reefs of the Philippines alone. [12] The harm upon the reefs is coming full circle and having a social impact through the limited fish stocks.
In the Philippines, where the practice has been well-documented, [2] blast fishing was known prior to World War I, as this activity is mentioned by Ernst Jünger in his book Storm of Steel. [3] One 1999 report estimated that some 70,000 fishermen (12% of the Philippines' total fishermen) engaged in the practice. [4]
It is estimated that 4,000 or more Filipino fish collectors have used over 1,000,000 kilograms (2,200,000 lb) of cyanide on Philippine reefs alone, about 150,000 kg per year. [16] A major catalyst of cyanide fishing is poverty within fishing communities. In countries like the Philippines that regularly employ cyanide, more than thirty percent ...
Dynamite fishing, cyanide fishing, and bottom trawling are fishing methods that cause extensive damage to coral reefs. [46] These practices are major threats to Philippine marine life and ecosystems. [46] Dynamite fishing, also known as blast fishing and fish bombing, was outlawed in 1932. [47]
