Understanding the Impacts of the Chinese Fishery Moratorium

Wei Zhou, ocean campaigner at Greenpeace East Asia’s Beijing office, used Global Fishing Watch to understand the impact of recent changes to fisheries policy in China on the extent of fishing in the Chinese EEZ.  On September 16, 2017 at noon, over 10,000 fishing vessels based in Zhejiang and Fujian Provinces in China headed out to start [...]

New Study: Greenhouse Gas Emissions are Rising as Vessel Traffic Grows

Commercial fishing is an energy-intensive business, and not just for the fishers hauling in the catch. Fishing vessels burn a lot of fuel. In fact, according to Naya Olmer, Marine Program Associate at the International Council on Clean Transportation, industrial-sized commercial fishing vessels are responsible for more than 4 percent of the greenhouse gas emissions released [...]

The Missing Data to Help Protect Seamounts

Chris Kerry, a researcher at the University of Exeter in the UK, is using Global Fishing Watch gridded data to understand if seamounts are targeted by fishing vessels and if fishing activity is linked to any specific seamount characteristic. Seamounts, or undersea mountains that rise from the ocean floor, create an environment rich with biodiversity. Yet [...]

Is banning transshipment necessary to diminish illegal fishing?

Christopher Ewell was an undergraduate student at New York University when he authored a publication on transshipment with Global Fishing Watch’s report, The Global View of Transshipment: Preliminary Findings, as an important source. Is banning transshipment necessary to diminish illegal fishing? It is according to a recent publication in Marine Policy, titled Potential ecological [...]

Citizen MPA Monitoring Via Global Fishing Watch

John Marrone is a Tasmanian citizen and recreational fisherman who monitors local Marine Protected Areas via Global Fishing Watch. John Marrone, a Tasmanian recreational fisherman, first became interested in Global Fishing Watch after watching a clip of funder Leonardo DiCaprio on a local news network. Upon hearing DiCaprio speak about Global Fishing [...]

Global Fishing Watch and the Case of the IUU Hotspots

Dr. Gohar Petrossian of John Jay College of Criminal Justice studies crime at sea. She is using Global Fishing Watch data as part of her effort to understand Illegal, Unreported, and Unregulated (IUU) fishing.  When most people hear the term “criminology” they think Sherlock Holmes or CSI. Dr. Gohar Petrossian is a criminologist who studies something we [...]

MPA Survey Hints at Complexity of Marine Conservation

The no-take marine reserve Motu Maha surrounds the Aukland Islands. Marine protected areas (MPAs) are among the best tools we have for conserving biodiversity in the oceans, protecting vulnerable marine life, and providing places of refuge for fish stocks. But do they work? Can vast areas of ocean really be regulated? And if [...]

Identifying Transshipment From the Data

When two ships meet to transfer goods, it is called transshipment. In the fisheries industry, it is sometimes legal in ports, but usually illegal out at sea where the practice can’t be monitored. [You can read more about it here]. Transshipment can facilitate the mixing of illegal or unreported catch with legal catch, making it [...]

Exploring a New World of Data with Team Member Aaron Roan

If you’ve grown accustomed to the idea that everything in our world is traceable—from airplanes to cell phones to personal browsing history and purchasing habits—it may seem like a no-brainer that we can use publicly broadcast Automatic Identification System (AIS) signals from ships at sea to find out where they are and what they’re doing. But in [...]

Tracking Fish and Ships

Where do sharks and boats cross paths? What about sea turtles and whales? If we knew this, maybe we could reduce the number of vulnerable marine animals that end up entangled  or accidentally caught in fishing gear. After years of monitoring large pelagic sea life with remote tracking devices, researchers have started to build a [...]

Teaching Machines to Tell Us About Fishing

None of what we’re doing at Global Fishing Watch would be possible without the advancements in computing power that have occurred in recent years. The volume of data we work with would have been overwhelming in the past. In one random sample, we observed more than 127,000 vessels over a 24-hour period broadcasting the Automatic [...]

What Ports Can Tell Us

Ports provide an important source of information to help us combat Illegal fishing and understand the science and economics of global fisheries. “They serve as the interface between land and sea for fishing vessels,” says Wessley Merten, our data and fisheries analyst at Oceana. “Wherever there’s a port, there’s an interaction. Whether it be offloading [...]

When Vessels Report False Locations

Occasionally, the AIS messages transmitted from a ship provide a location that makes no sense, say, in the middle of the Antarctic or over a mountain range. In such cases, either the AIS transponder has malfunctioned, the data got scrambled in transmission, or the system has been tampered with in a deliberate attempt to disguise [...]

Diversity Expedition Update

Last week we reported on an expedition to survey diversity in the deep sea off the coast of Southern California. The goal of the expedition was to document on video the diversity of deep sea diversity in the area and demonstrate the need to close the waters of the Southern California Bight to bottom trawl fishing which destroys [...]
