Google Earth Images Reveal Fisheries Are Catching More Than They’re Reporting
Don’t tell tall tales about your next fishing trip, because Google Earth might just grass you up. Every year the nations surrounding the Persian Gulf report how much fish they pull from their shores. In 2005, the reported total was 5,260 metric tons. But scientists at the University of British Columbia smelled something fishy, so they turned to a new research tool in the battle against bad reporting: Google Earth.
The fishermen in the Persian Gulf region use traps that are so huge, they’re visible from space. Called fishing weirs, the tidal traps catch marine life as the ocean level rises and falls. After inspecting thousands of miles of coastlines in Google Earth, the Canadian researchers counted 1,900 fishing weirs–far more than the number on record. The scientists now estimate the annual fish haul in 2005 was closer to 31,000 metric tons–six times what was reported to officials. They published a report on their findings in the ICES Journal of Marine Science.
Fishing weirs have been used to catch fish for thousands of years, but satellite technology is only now giving scientists a sense of how they interact with the environment. And the use of satellite technology to double check reported data about wildlife harvesting gives scientists a new tool for understanding and managing the environment.
“Because countries don’t provide reliable information on their fisheries’ catches, we need to expand our thinking and look at other sources of information and new technologies to tell us about what’s happening in our oceans,” explained the study’s co-author, Daniel Pauly.

Reef-World launch new toolkit in response to the current global coral bleaching event
The Reef-World Foundation – international coordinator of the UN Environment Programme’s Green Fins initiative – has launched a new coral bleaching toolkit in response to the 4th global coral bleaching event confirmed by the National Oceanic & Atmospheric Administration (NOAA) and International Coral Reef Initiative (ICRI) in April 2024.
The Green Fins Global Coral Bleaching Response Toolkit provides guidance to the marine tourism industry on how they can help manage and monitor the impacts of coral bleaching and get involved in recovery efforts. It features information about coral bleaching, including the causes, impacts and response strategies. The toolkit is compiled from a variety of readily available resources from multiple organizations and initiatives, such as ICRI, Coral Reef Alliance, Reef Check and NOAA, along with Green Fins materials, to ensure it is accessible to everyone. These resources cover methods for reducing local impacts, monitoring the reefs and engaging tourists and local communities.
The El Niño phenomenon has been present since February 2023, which has led to persistently warmer temperatures being experienced around the world and has affected the sea surface temperatures. Coral bleaching has been recorded in all ocean regions ever since. While this event is widespread and serious, there is still hope as bleached corals are not dead corals. Corals can survive bleaching events and thrive if they are given the time to adapt to the changing climate.
“Coral reefs are under a huge amount of stress every day and that reduces their chance of recovery from bleaching events,” said Chloe Harvey, Executive Director at The Reef-World Foundation. “However, this time around the scientists have been watching the data closely, so we’re prepared. We understand what it means and we know what we need to do to respond to it. This global event calls for global action to protect these vital ecosystems for generations to come.”
By equipping the industry with the necessary knowledge and tools, Reef-World hopes to empower these key stakeholders to play a crucial role in preserving the health and resilience of our precious coral reef ecosystems. Reef-World believes that with the right resources, the marine tourism industry can be a driving force in the fight against coral bleaching and contribute significantly to the long-term sustainability of marine environments.
With this momentum, other key players in the industry, such as PADI AWARE Foundation and NOAA, have gotten on board the campaign for more citizen scientists to help out in monitoring coral bleaching. With the toolkit available to all, The Reef-World Foundation is looking forward to more collaborative actions in the industry.
