Seeking to gain a high-tech edge over illegal fishers, the Government of Belize will use “eyes in the sky” to enforce fishing regulations in the biodiverse Glover’s Reef Marine Reserve and other reef systems in what is the first use of conservation drones to monitor marine protected areas.

Dredging activity near coral reefs can increase the frequency of diseases affecting corals. researchers say after a a world-first study. 'At dredging sites, we found more than twice as much coral disease than at our control sites,' says the lead author of the study. "Corals require both light and food to survive," researchers explain. "And unfortunately, dredging impacts corals on two fronts: increased turbidity means less light for photosynthesis, while increased levels of sediment falling onto the coral can interfere with their ability to feed."

A new report shows that no-take zones in Belize can not only help economically valuable species such as lobster, conch, and fish recover from overfishing, but may also help re-colonize nearby reef areas. According to past studies, the recovery of lobster, conch, and other exploited species within marine protected areas with no-take zones, or fully protected reserves, could take as little as 1-6 years. Full recovery of exploited species, however, could take decades.

The future health of the world’s coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat -— and to be flexible about the type of algae it cooperates with. In the first study of its kind, scientists discovered that corals -- tiny reef-forming animals that live symbiotically with algae -- are better able to recover from yearly bouts of heat stress, called "bleaching," when they keep large energy reserves -- mostly as fat -- socked away in their cells.

A new study on biological erosion of mesophotic tropical coral reefs, which are low energy reef environments between 30-150 meters deep, provides new insights into processes that affect the overall structure of these important ecosystems. The purpose of the study was to better understand how bioerosion rates and distribution of bioeroding organisms, such as fish, mollusks and sponges, differ between mesophotic reefs and their shallow-water counterparts and the implications of those variations on the sustainability of the reef structure.

Biologists have shown that inhabited coral islands that engage in commercial fishing dramatically alter their nearby reef ecosystems, disturbing the microbes, corals, algae and fish that call the reef home.

With only about one-sixth of the original coral cover left, most Caribbean coral reefs may disappear in the next 20 years, primarily due to the loss of grazers in the region, according to a new report. The results show that the Caribbean corals have declined by more than 50% since the 1970s.

Construction of two new fish-spawning reefs is about to begin in the St. Clair River northeast of Detroit, the latest chapter in a decade-plus effort to restore native species such as lake sturgeon, walleye and lake whitefish. The new reefs will be built this summer and fall at two locations on the St. Clair. The goal of the project is to boost fish populations by providing river-bottom rock structures suitable for spawning.
