Dynamite, cyanide en diving
Dynamite and cyanide
Dynamite and cyanide are catching methods often used at coral reefs. Cyanide is used to prevent damage to the coral reef. Dynamite and cyanide kill or stun fish, causing them to float to the surface. These methods of fishing are illegal, but are still practiced. It is a very effective method, but really damaging and also toxic.
Diving as fishing method is often used for vulnerable and expensive shellfish and crustaceans. The shellfish and crustaceans are collected by hand. Sometimes it is needed to dive very deep. The Dutch cockle fishery uses a kind of rake to collect the cockles. This is a labour intensive activity. This method is very selective and does not damage the seabed.
