It has long been thought that coral fish start life in a coastal nursery, such as mangrove or seagrass, before migrating to a coral reef. Fish use a variety of nursery habitats and may migrate very long distances from coastal wetlands across deep open water. This implies that it isn’t enough to protect adult habitat on coral reefs. Habitats that supply those reefs and the migration corridors that connect them also need protection.
The UK today ran out of fish from her own waters, and became dependent on imported fish for the rest of the year, according...
Bright yellow eyes distinguish the Midnight Snapper (Macolor macularis) from related species. You find it in the Western Pacific between 3 and 50 m,...
The mighty potato cod of Australia and the Pacific grows to 2 m long and can weigh 110 kg (242 lbs or over 17...
Intense exploitation over millennia has depleted Mediterranean Sea species from the large to the small. What would a ‘healthy’ Mediterranean rocky bottom look like? There are no pristine sites (i.e. undisturbed by humans) left in the Mediterranean against which to compare the health of current ecosystems. SCUBA divers surveyed the rocky reefs throughout the Med, from Morocco to Turkey.
Jobs, ecotourism and diving industries can benefit from having a diverse supply of weed-eating fish on the world’s coral reefs, scientists say. Despite their small size, relative to the sharks and whales that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, according to a study published this month in the journal Ecology.
The scorpionfish is one of the most venomous fish in the world. Its poison causes severe pain and paralysis. This scorpionfish is extermely well-camouflaged: it can change colour to match its background and has many "tassles" masking its outline.
For centuries, it has been believed that selective fishing that avoids young, rare and charismatic species and focuses on older and larger individuals, is key to increased harvest and reduced impacts on the environment. But this has serious evolutionary side effects. A new approach proposed by IUCN, called ‘balanced harvesting’, involves targeting more species and sizes.
New sensor system monitors fishing gear and can replace human observation of fishing activities. The system monitors key fishing gear and triggers a video cameras when it detects fishing activity.
The latest update of The IUCN Red List of Threatened Species reveals two species of Manta Ray are vulnerable, and the situation is particularly serious for tunas. Among the marine species classified as critically endangered – the most serious risk category – are staghorn and elkhorn coral, the hawksbill turtle and the Mediterranean Monk Seal. The marine realm though is very poorly covered in the IUCN Red List, comprising less than 5% of the species included.
