Fishing and farming methods

Dynamite, cyanide en diving

Dynamite and cyanide

Dynamite and cyanide are catching methods that are often used around coral reefs to prevent damage from nets and other fishing gear. Dynamite and cyanide kill or stun fish, causing them to float to the surface. These methods of fishing are illegal but are still being used. It is a very effective method, but very damaging and also toxic.


Fishing by diving is often used to ‘catch’ vulnerable and expensive shellfish or crustaceans as they are collected by hand. Sometimes collection even takes place at great depths. The Dutch cockle fishery uses a kind of rake to collect the cockles. This is a labour-intensive activity but is very selective and does not damage the seabed.
