Coral reef fish

Coral reef fish is a term used for the often brightly coloured fish found in tropical or subtropical waters. Many are not commonly sold in Dutch shops and restaurants. Species in this category include parrotfish, snappers, lionfish and surgeonfish.

It is often difficult to determine how these fish were caught. In countries where these species occur, fisheries management is also often insufficient to monitor the stocks properly. Catches are poorly recorded and control of fishing techniques is limited. For example, fishing with explosives and cyanide sometimes takes place on and around coral reefs. This has disastrous ecological consequences for reefs, which are nurseries for the ocean.

Parrotfish

Parrotfish are often brightly coloured and have a mouth that looks like a parrot’s beak. Some species of parrotfish can grow to be 1 m in length but often stay smaller. Parrotfish show very social behaviour, living in small groups on coral reefs. They use their specialized beak and teeth to scrape algae from the corals. They consume the algae and excrete the indigestible parts. In fact most of the beautiful, white tropical beaches consist for a large part of parrotfish poop.

Final assessment

Explanation assessment

There is a lack of data on the fishery on parrotfish in this area. Although the family of parrotfishes are regarded as intermediately vulnerable to fishing pressure, the lack of data makes it unclear. The increased fishing pressure in the Philippines of the last 10-20 years has led to local extinctions of parrotfish.

The fishing with gillnetsGillnets:
A fishing technique whereby passing fish get caught in the meshes with their gills. The net stands vertically on the bottom or hangs on buoys in the water column. The by-catch of species such as porpoises and dolphins is a problem related to gillnets. is not selective and there is bycatch of many species, including sea turtles, sharks and dolphins. Parrotfish live on coral reefs, where they play a crucial role in the ecosystem. Also, the gillnets get tangled up with the branches of the coral and cause damage in this way.

There is little information on the management of this area.
