The live food trade usually uses hook-and-line techniques, but the use of cyanide fishing is also known. [9] Data is limited, but it is thought the catch of live fish was around 200,000 kilograms (440,000 lb) in 1994 and 800,000 kilograms (1,800,000 lb) in 1997, of which 95% was exported, although this period also saw localized declines.
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 ...
Of fish ponds being leased from the government, the majority are leased by individuals with addresses in different locations to those of their fish ponds. Almost all freshwater fishponds are privately owned. [16] Fish pond land can be leased from the government for a minimum of 25 years and a maximum of 50 years under the Fisheries Code of 1998.
The capture of small pelagic fish plateaued after 1975, despite still-increasing fishing effort. [9]: 2 Capture effort for each municipal pelagic fish had already peaked in the 1950s. All fishing in the Lingayen Gulf peaked per unit effort in the late 1970s, after which it declined.
A basnig boat: a bangka equipped with lift nets. Commercial fishing boats are defined through the Philippine Fisheries Code of 1998 (RA 8550), [1] which defines fishing scale by boat size: 3.1 to 20 gross tonnes as small-scale, 20.1 to 150 gross tonnes as medium-scale, and anything larger as large-scale.

Cyanide fishing is a method to capture live fish for the international aquarium trade and, more recently, to supply restaurant demand for live reef fish. [11] This method involves spraying sodium cyanide into the targeted fish's habitat as a way to stun the fish without killing them. [12]
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
Global fish production peaked at about 171 million tonnes in 2016, with aquaculture representing 47 percent of the total and 53 percent if non-food uses (including reduction to fishmeal and fish oil) are excluded. With capture fishery production relatively static since the late 1980s, aquaculture has been responsible for the continuing growth ...
